Geologists working to step up tsunami mapping
Washington faces the second highest risk from earthquakes, and one of the highest for tsunamis in the nation, yet remains the only west coast state that does not have an inventory of the seismic hazard for critical infrastructure.
Thanks to the state Legislature this year, DNR has more resources to address that gap. We received funding in the supplemental state budget to identify geologic hazards and produce information you and our communities can use to be ready.
DNR received $1.2 million to study the seismic stability of 220 schools and five fire stations, and to work with engineers from the University of Washington and private firms to help provide plans to make those critical buildings more stable during seismic events.
We also received an appropriation for $367,000 to hire more geologists to study and map tsunami hazards along the Washington coast, which is currently only about half-mapped.
All this will help communities be more resilient for the next tsunami, whether that’s from a Cascadia subduction event or less famous faults.
DNR holds scenarios developed to show how seismic forces could impact all of Washington’s communities, from Aberdeen to Zillah.
Our geologists just published new maps to show the tsunami risks to southwest Washington from a 2,500-year Cascadia subduction zone earthquake so people along the coast can identify evacuation routes before the quake and tsunami hits.
The first tip is to be ready. Have plans for what to do when earthquakes or tsunamis happen.
In addition to developing plans to prepare for natural disasters like our friends at Washington Emergency Management advise, you can know more about what these geologic hazards likely mean for your neighborhood, thanks to the hard work of our geologists.
You can view scenarios for the different seismic hazards Washington faces on our seismic hazard catalog.
You can find out more about the risks Washington’s active geology present to you and your loved ones with the scenario catalog or by the hundreds of reports on Washington geology filed in the Washington Geology Library. Those reports can also be accessed online through our new publications catalog.
Yuo can learn more by talking with our geologists and our colleagues at EMD, the National Weather Service, the University of Washington and local emergency management officials at our Tsunami Roadshow April 10-13.
Public presentations will be:
- 1 p.m., Tuesday, April 10 at Raymond Timberland Library,507 Duryea St. in Raymond
- 7 p.m., Tuesday, April 10, Columbia Pacific Heritage Museum 115 Lake Street SE, in Ilwaco.
- 12 p.m., Wednesday, April 11 at the Ocosta Junior-Senior High School Library, 2580 Montesano St, Westport;
- 6 p.m., Wednesday, April 11 at the Ocean Shores Convention Center, 120 W. Chance a La Mer NW, Ocean Shores.
- 11 a.m., Friday, April 13 at the J-47 Pirate Union Building (PUB) on Peninsula College, 1502 E Lauridsen Blvd, Port Angeles
- 6:30 p.m., Friday, April 13 at Chimacum High School auditorium, 91 West Valley Rd., Chimacum.
Lessons from the 1964 Alaska Earthquake and Tsunami
Fifty-four years ago today, at 5:36 pm, a powerful magnitude 9.2 earthquake shook the coast of Alaska southeast of Anchorage. It was one of the two strongest earthquakes ever recorded anywhere. The shaking lasted almost 4.5 minutes! The quake killed many people in Alaska, but what may be surprising is that 16 people died in Oregon and California, more than 1,300 miles away. How did this happen?

The Alaska earthquake unleashed a massive tsunami that rushed across the Pacific, reaching the Washington coast in fewer than four hours. The waves reached heights of up to twelve feet in Seaview. People on the beach were unprepared for the tsunami. In those days we did not yet have a good tsunami warning system for alerting people living on the coast of imminent danger.
Washington is gearing up for ‘the big one’, a great Cascadia subduction zone earthquake predicted to strike right off…

Natural features that define our state
How would you go about inventorying the species and ecosystems in Washington state? Or determining conservation priorities?
At the DNR Natural Heritage Program, working with our citizen advisors on the Washington State Natural Heritage Advisory Council, we’ve been documenting the location of rare species and high quality ecosystems since 1977. Educators, local governments, state and federal agencies, and many others rely on this information for their work.
The just-released 2018 State of Washington Natural Heritage Plan offers an opportunity to reflect on the natural features that define our state. Flipping through the short 30-page plan, you’ll begin to see Washington through the eyes of the many species with which we share the state, and learn about the framework created by the Washington State Legislature
The 2018 Natural Heritage Planto achieve conservation, both successfully and efficiently.
Commissioner of Public Lands Hilary Franz released the plan with encouragement for everyone:
We invite you to help us build on this conservation legacy. We seek partnerships with agencies and land trusts to fill the gaps that exist in knowledge and conservation action. We encourage school districts and individual teachers who are interested in providing outdoor learning experiences to contact us.
Get outside this spring, and share our rich natural heritage with future generations of Washingtonians!
On the Move: How Mobile Technology is Changing the Way DNR Collects Spatial Data
When the iPhone came out in 2007, we had never seen the like: a smart phone with a large, relatively simple LCD screen you could operate by touch that would bring web pages to life in vivid color right there in your hand. Suddenly, smart phones were cool. Mainstream. We had to have one. Ten years later, most of us do.
Who could have guessed that devices tailor-made to deliver soup recipes, memes, and polarizing opinions in 140 characters or fewer would become the future of spatial data collection at a large land management agency such as DNR?
And yet, here we are.
Change is comingManaging more than two million acres of public lands for everything from timber harvest to wheat farm leases technically does not require reams of spatial data. But it definitely helps.
Spatial data indicates where something is in relation to something else. Fed into a geographic information system (GIS), spatial data helps DNR locate, track, analyze, map, and ultimately manage the lands and resources in our care.
Figure 1. Trimble data collector.Currently, DNR field staff collect spatial data using global position system (GPS) receivers and data collectors, which are hand-held devices for entering data. The most common brand used at DNR is Trimble (Figure 1). Foresters use these devices to map streams or timber sale boundaries. Biologists use them to survey nest trees. Geologists use them to map potentially unstable areas. If their jobs are mostly reconnaissance, field staff may opt for a Garmin GPS, which is more limited in terms of data collection.
Trimble and Garmin collection devices have been solid workhorses at DNR for nearly a dozen years. But there are issues. First, Trimble data collectors run on a Windows Mobile operating system that has not been supported since 2008. Second, ESRI’s ArcPad, the software used to collect data on the Trimble devices, also is headed to extinction. (ESRI is the supplier of widely used mapping and geographic software.)
DNR will continue to use and support Trimble and Garmin collection devices as long as feasible, but when they fail, they will not be replaced. Why would they? Aside from the software issues, it is time for DNR’s technology to evolve. Tasks done on Trimble and Garmin collection devices now can be done on the ubiquitous smart phone or its larger cousin, the smart tablet. That is where ESRI is headed. That is where most everything is headed. Why? Because so many of us are using these small, portable devices, and because today’s smart phones and smart tablets can be as powerful as a desktop computer.
“New code is mostly being developed for smart devices. They are considered the most current tech platform,” says George Jenkins, an IT specialist in DNR’s South Puget Sound (SPS) Region headquartered in Enumclaw. “Private industry is already on board with using smart devices,” he added.
Avenza Maps and ESRI CollectorHow can smart devices replace DNR’s Trimble and Garmin collection devices? One way is through Avenza Maps, which is software designed to read a georeferenced PDF map. “Georeferenced” means the PDF has location coordinates that relate the map to a location in physical space.
Figure 2. Avenza Maps on a smart phone. The blue dot indicates where you are. Shown here is a georeferenced briefing map for the Chelan Complex fire.One useful feature of Avenza Maps is its ability to show users where they are in relation to the map. Because the smart device is pulling in a GPS signal or triangulating location from cell towers, users will see a blue dot on the screen for their current location (Figure 2). That dot should move when they do. “No matter where you go, there you are” takes on new meaning with these maps.
These maps work whether users have cellular coverage or not because maps can be cached to their smart devices before they leave cellular coverage. Maps are available in the Avenza Maps online store, or users can make their own using GIS.
Avenza Maps also can be used to collect data. For example, a DNR biologist can set a point on the map for a marbled murrelet platform tree, enter descriptive information, and even take a photo linked to that point. The biologist can record the route he or she took to reach that tree. And the points, lines, and polygons collected with Avenza Maps can be saved as shape files and brought into a GIS program like ESRI’s ArcGIS.
One enthusiastic user of Avenza Maps is Alan Mainwaring, a biologist with DNR’s South Puget Sound Region. Alan was an early adopter of mobile technology; his first smart phone was a Blackberry, with its tiny screen and rows of little buttons. The modern smart phone “is like having a file cabinet full of information that is always with you,” he said.
For field work, Alan points out that with a georeferenced PDF “you can easily find your way to places you have never been.” Such maps proved highly useful at the Chelan Complex fire in 2015 (Figure 2). He also notes that a georeferenced PDF can make it easier for users to direct someone to their location in the event of an emergency.
Avenza Maps is a good choice for many of DNR’s programs. It is inexpensive, easy to use, and has data collection capabilities sufficient for many tasks. Its appeal is reflected in its use: DNR IT specialist Jeffrey Holden estimates that at least 500 DNR staff are using it already. However, DNR also needs a way to collect more complex information, particularly on projects that involve multiple team members. For that, DNR selected ESRI’s Collector, or Collector for short.
Collector is an example of “mobile GIS,” which means (as it sounds) taking GIS out of the office and into the field. Collector enables users in the field to view and collect spatial data on a smart phone or tablet and upload (sync) that data directly into a geodatabase, which is a database capable of holding spatial data.
Similar to Avenza, Collector can be used without cellular coverage. Everything needed can be saved to a smart device before users leaves for the field, and the data collected can be synced when they return to coverage.
Because Collector is designed for those with little or no GIS experience, it is simple to use. Assuming they have Collector installed, users can log onto ArcGIS online (ESRI’s cloud server) and download a “web map” to their devices (Figure 3). (Downloading is not necessary if users will be working in an area with coverage; they can simply open the map from the Collector application and start using it.)
Figure 3. Web maps available on ArcGIS Online (Tablet shown). Figure 4. A web map with a base map and data layers. The user clicked on the red polygon to bring up its attributes.Designed to view and collect data, the web map likely will contain a base map for reference, a number of map layers, and tables with related, non-spatial information (“attribute tables”) (Figure 4). If the web map was designed for information and navigation only, most of those layers and attribute tables likely will be locked to prevent editing. If the web map was designed for collecting specific types of data, it may contain a number of empty map layers for collecting new points, lines, or polygons.
To begin collecting data, users tap on the new feature tab (Figure 5) and then select the layer for the type of point, line, or polygon they wish to collect.
Figure 5. Layers for collecting a new feature.If the new feature is a point, Collector can add a point to the map right where they are standing. Or they can tap the map where they wish the point to be. If the new feature is a line or polygon, they can draw it on the map or ask Collector to drop points on the map at intervals as they walk. They also can enter non-spatial information into the attribute table (Figure 6) and even take a photo and attach it to the table.
Collector also can be configured to open a custom-built form in an ESRI application called “Survey 123.” (Users must have Survey 123 loaded on their smart device for this to work). Survey 123 can be used to enter information that is too complex for the simple attribute tables in Collector (Figure 7).
Figure 6. Simple table for entering non-spatial data.Once collected, spatial and non-spatial data can be synced to the geodatabase with one tap of a button. If users do not have cell coverage where they are, the data will be stored on their device to sync later, as mentioned previously.
Once the data is synced, anyone with access to the geodatabase can view it. The advantages of that are many. Say a project involves multiple people fanning out into different areas to collect data. Periodically, those people could return to an area with coverage and upload what they collected. The project manager can review it on the spot and provide feedback. That might save a trip back out to the field later to correct something. Someone in the office working on the database who notices a problem or needs to make an update can do so, and if they have cellular coverage, the people in the field will have those updates before they climb back in the truck.
Figure 7: Form created with Survey 123The alternative is for DNR staff to continue using Trimble collection devices as they do now: finish collecting, drive back to the office, transfer the data from the device to the network, and then post-process the data. That takes time. How much time? Well, consider the Pacific Cascades Region, headquartered in Castle Rock. Region foresters “put up anywhere from 40 to 60 timber sales per year, and work on three years’ worth of timber sales at once,” says Shawn. Time spent on repetitive layout tasks can add up. With Collector, field staff possibly can spend more time doing what they typically want to do: work in the woods, not in the office.
What about the position accuracy of smart devices? Currently, the GPS in smart devices typically ranks toward the bottom of the scale in terms of accuracy.
No problem, explains Shawn. Smart devices can be linked with small, wireless Global Navigation Satellite System (GNSS) receivers (Figure 8) to boost position accuracy. Just like GPS, GNSS receivers pull signals from satellites to determine a position on the globe. But whereas a GPS device pulls in signals from a US-controlled satellite constellation, a GNSS device receives signals from multiple satellite constellations controlled by multiple countries. A GNSS receiver is more accurate than a GPS receiver because it has access to more satellites.
Figure 8. GNSS receiver. Photo courtesy of Compass Tools, Inc.Also, smart device technology is improving all the time. As George points out, in 2018 or 2019 GNSS receivers may be integrated into smart devices via a new computer chip. That chip could give smart devices accuracy down to the centimeter. This type of accuracy is where the smart device industry is headed, thanks to consumer demand.
Next StepsThe transition to smart devices at DNR has begun, but it will take time. DNR IT specialists are developing and documenting workflows for using the new equipment and software, producing georeferenced maps for Avenza and base maps for Collector, and developing instructions and other information. In the meantime, DNR staff will continue to use older devices (Figure 9).
Figure 9. Jeffrey Holden and all of the devices currently in use at DNR.So how does the future look? It might involve viewing and picking up projects from fellow employees using a shared geodatabase updated through Collector. It might require fewer trips from the field to the office. It might even involve topping a truck with an antenna and cell phone booster, a small device that can make it easier to pick up a cellular signal in a remote area.
Regardless, it is clear that the future is here. And it involves a smart device.

Fire Districts: grants open March 9 for Volunteer Fire Assistance Phase 1
Several factors affect the impact of wildfire in Washington, including the capacity of rural fire districts to respond to wildfires.
That’s where DNR’s Fire District Assistance Program can help. We administer grants to help local fire districts and departments obtain more resources.
The Phase I grant program allows eligible districts to order personal protective equipment and other fire equipment at 50 percent cost through the DNR fire cache starting March 9, 2018. USDA Forest Service Volunteer Fire Assistance grant funding covers the remaining 50 percent cost. Districts apply online using the Phase I Order, an online shopping cart that allows districts to submit orders directly to DNR. This grant funding helps eligible rural fire districts across Washington state buy new fire and safety equipment.
Districts and departments can place orders through the online shopping cart until April 27, 2018 or until grant funding is expended, whichever occurs first.
Interested? Learn more at the DNR Fire District Assistance webpage for eligibility requirements and ordering process.
Nisqually quake lessons live on 17 years later
It’s been a 17 years since Washington felt its last damaging earthquake.
At 10:54 a.m. on Feb. 28, 2001 a magnitude 6.8 earthquake struck near Anderson Island. Known as the Nisqually Earthquake, the temblor shook the Pacific Northwest, with shaking being felt around Puget Sound, in Vancouver, B.C., Portland, Ore., and as far east as Montana. The Nisqually earthquake produced some $2 billion in damages and injured about 400 people.
Damage could have been much worse, according to reports prepared by the Washington Geological Survey. This quake stemmed from the Benioff zone, meaning it came from deep underground (more than 32 miles underground.) The depth of the epicenter meant much of its force was buffered by layers of earth.
But on the plus side, the Nisqually quake was responsible for a new set of preparedness measures and research into Washington’s tectonics.
Boosted efforts to map, research faultsIn the last 15 years, the number of seismic monitors has more than tripled across the northwest ; GPS units have been deployed for faster earthquake detection; mapping efforts have been boosted by the use of LiDAR, which has led to the detection of new faults in the Puget Sound area.
This map shows areas of seismic risk from high (red) to low (grayish-green) and is from a 2007 report on the seismic design categories in Washington.DNR has used much of that research to produce the Washington State Seismic Scenario Portal, which shows estimates of damage from future quakes of differing magnitude on our state’s many faults. We’ve also worked to document damages from Washington’s historic temblors.
DNR worked with the Washington Emergency Management Division and federal agencies to publish estimates of the potential losses from a magnitude 7.2 earthquake on the Nisqually fault zone. The fault runs beneath Pierce and Thurston counties but 15 other counties would feel this impact, including King County, which would suffer significant damage along with Pierce and Thurston counties.
Working to further knowledgeDNR is working to secure funding from the legislature to identify and map more faults and tsunami risks so communities will have the information they need to mitigate potential damages in advance.
Falling debris like these bricks that fell off the Washington Federal Bank in Olympia during the 2001 Nisqually earthquake are one of the top causes of injuries during an earthquake. Photo by Steve Bloom, The Olympian.DNR hazards seismologists have also worked on projects to determine how earthquake waves move through soils around schools so they can be strengthened to better withstand future quakes.
When an earthquake happens, there will not be time to Google what you are supposed to do (Drop! Cover! Hold On!). After the earthquake, the internet might not work at all.
For now, you can turn to DNR’s Emergency Preparedness page to find out what you can do in advance of the next big one.
The need to improve our earthquake and tsunami response
Washington faces the second highest risk from earthquakes, and one of
our nation’s highest risks for tsunamis, yet we remain the only west coast
state that does not have a seismic hazard inventory for critical infrastructure.
That’s not all: many communities along our coast have either outdated tsunami
inundation maps — or no maps at all.
The stakes are huge. A Cascadia subduction zone earthquake and tsunami would cause more than $50 billion in damages and more than 10,000 deaths in Washington
state – and those are 2010 estimates.
That’s why I’ve asked the Legislature to provide DNR with $543,200 for FY2019 and an ongoing appropriation of $493,200 to hire two geologists and one IT technician to identify and map earthquake and tsunami hazards.
With this additional staff on board DNR will be able to produce:
- Tsunami and earthquake hazard maps;
- An inventory of the geologic risks to critical infrastructure like
ports, schools and hospitals; (this will take 10 years of only one staff member is added and will not happen if no funding is appropriated); - Critical information for emergency responders to build quick
response plans; - Reliable data for city and county planners to use in zoning
determinations; - Tsunami evacuation maps for all coastal communities; and
- Public education tools for geologic hazards.
We don’t know when the next Cascadia subduction zone earthquake and tsunami will occur but one thing is certain: it will happen again. For a modest investment now, we can help the people of Washington become far better prepared for the next major disaster.

Public Lands Commissioner Hilary Franz on Safeguarding the Public from Landslide Risk
Washington faces one of the highest landslide risks in the nation. In 2017, we had 155 reported landslides, most of which passed without notice or concern. But this year we only have to look at Rattlesnake Ridge to see the danger that landslides pose to people and property. I’m calling on Governor Inslee and the state Legislature to fund critical services and provide the tools we need to minimize the risks landslides pose to public safety. Namely:
I’m asking for $460,000 for engineers to help ensure that logging roads are built safely and won’t trigger unstable slopes. We’ve seen a 10-fold increase in road applications around potentially unstable slopes over the last 6 years. My agency, The Department of Natural Resources, seeks more engineers to properly review each application and ensure public safety.
I’m asking for $1.6 million to study the SR 530 corridor, allowing us to determine the cause of the Oso landslide. More than 3 years after the slide, the cause of the Oso landslide remains unknown. This funding will put geologists on the ground, where they will map and drill into the earth to further analyze this 50-square mile corridor. By studying the SR 530 corridor, we will gain insights into how Oso and other glacial deep-seated landslides occur, improving our ability to anticipate landslides throughout the state. Counties with similar geology include King, Pierce, Thurston, Okanogan, Douglas, Chelan, Ferry, Stevens, Pend Oreille, Clallam, Whatcom, Skagit, Snohomish, Mason, Kitsap, Island, Jefferson and San Juan.
I put forth these funding requests in the Washington State Department of Natural Resource’s original October supplemental budget request to the legislature. Today, we know from a recent Climate Risk Assessment that more frequent periods of heavy rainfall during Washington’s rainy seasons will lead to an increasing amount of landslides. Please know that I continue to work on this with Governor Inslee and the state Legislature.

Getting an early jump on fire season
Last week I got the opportunity to speak to 150 fire commissioners and fire chiefs, the brave men and women who make up our local fire districts. Our partnership is a critical part of DNR’s wildfire response; together we’re able to protect people, communities and resources from wildfire. We’ll be coming together again this spring, when we’ll lead an inter-agency training for nearly 1,000 firefighters.
Time together before we face the challenges of wildfire season is critical. I shared with them my vision for managing vegetation and fuels, protecting communities, reducing human caused wildfires and safely and effectively responding to wildfires.
As we now work together with our local state and federal partners to develop my 20-Year Forest Health Strategic Plan for Eastern Washington, I emphasized how the change we’re seeking in the health of our forests won’t happen immediately. We need to continue to do all we can to protect people, communities and our natural resources from the threat of wildfire. Part of that will come with additional funding, which is why I’m requesting $1.7 million from the legislature this year to train more firefighters, increase fire response and readiness in Western Washington, and improve systems for wildfire data, finance, forest health and firefighting resources.
I want to thank the fire personnel who joined me this week and to all who continue to persevere in making our communities and resources more resilient.

More Ponderosa Pines Killed by Western Pine Beetle
The western pine beetle is a native bark beetle found in eastern Washington that can kill ponderosa pine, its only host in the state. In typical years, they hang around in low populations attacking weakened, diseased or older ponderosa pines. They are frequently found in trees weakened by root diseases, such as armillaria. When trees experience severe drought stress, as they did in 2015, the western pine beetle can more easily overcome the resin flow defenses of water-stressed trees.
High numbers of stressed trees produce more beetle offspring and can lead to large outbreak populations. Aerial surveys in Washington recorded 12,900 acres with western pine beetle-caused mortality in 2016, more than double the amount in 2015, and the highest level since 2008. Typically, there is a year-long delay between beetle attack and visible crown symptoms. Drought damage can also have lasting effects on tree vigor and western pine beetle populations may continue to build, so mortality is likely to increase. The most recent large outbreak in Washington was 2003-2004, with over 120,000 acres affected each year.
The pattern left on the landscape is patchy groups of orange or red ponderosa pines. This “group kill” is a result of pheromones used by the beetles to coordinate mass-attacks and concentrate beetles from the surrounding area.
Female western pine beetles that make it past bark and resin will lay eggs in the sugary phloem layer of the inner bark in the main bole of the tree. Hundreds of their larval offspring mine in the phloem, disrupting the vital flow of sugars and girdle the tree.
PHOTO 1: Western pine beetles can introduce bluestain fungi that grow into the sapwood, eventually causing tree death. Photo: US Forest Service.Western pine beetle also introduces bluestain fungi (See Photo 1) that grow into the sapwood and interrupt flow of water in the xylem layer, hastening tree death. In addition to copious resin flow that might fend off bark beetle attacks, healthy trees are induced by attacks to actively produce high levels of terpenes which can be toxic to bark beetle larvae. This response is reduced in weakened or stressed trees, resulting in higher beetle reproductive success and a larger “brood.” To make matters worse for the trees, western pine beetle can produce up to two overlapping generations per year in Washington.
There are three other species of bark beetles that may aggressively attack and damage ponderosa pine. Mountain pine beetle occupy the same niche as western pine beetle in the main bole, but mountain pine beetle outbreaks in ponderosa pine are more likely to occur in higher elevation areas near lodgepole pine, its preferred host. The red turpentine beetle prefers to attack the lower eight feet of the main bole and ips pine engravers can attack smaller diameter tops and branches. It is possible to find all three species in the same tree. These double- or triple-whammies will certainly decrease chances of tree survival.
PHOTO 2: Western pine beetle egg galleries. Photo: William M. Ciesla, Bugwood.orgSuccessful western pine beetle attacks are easy to identify and differentiate from the other bark beetle species. Since western pine beetle is the only one that pupates in the outer bark, their larvae, pupae, and newly developed adults are easily accessible for predators, such as woodpeckers. Look for patches of bright orange bark where woodpeckers have flaked off the darker outer bark, a tell-tale sign of western pine beetle activity. Popcorn-sized pitch tubes may be visible on the bark surface, but these are less common than with mountain pine beetle. The surest way to confirm western pine beetle is to remove a patch of bark and look for the winding, serpentine egg galleries in the layer between bark and sapwood that do not change in width (Photo 2). When new brood adults emerge from the tree, they leave behind perfectly round exit holes a few millimeters across.
What Can Landowner Owners Do?Orange crowns will certainly get the attention of landowners who will want to take action to manage the problem. Keep in mind that the crown often dries out the season after beetles killed it, so they may have already moved on. If exit holes are present and numerous, nothing will be gained (in terms of managing beetle numbers) by tree removal. Trees with green crowns that have woodpecker activity or pitch tubes with no exit holes may still contain beetles. Removal of these “green attacked” trees may help reduce beetle populations. During an outbreak, this approach is likely a losing battle since beetles can fly in from nearby areas. The best management practice for bark beetles is to control competing vegetation and increase vigor and resilience of the healthiest trees in a stand.
Direct control methods such as pesticides can be effective in preventing attacks to high value trees but will do nothing to save a tree that’s already infested. There is a commercially available pheromone called verbenone that is marketed as a pine bark beetle repellant. Verbenone can be effective with mountain pine beetle in some situations, but for western pine beetle and ips pine engravers, the current formulation hasn’t worked well in field testing.
Ponderosa pine mortality from western pine beetle may be high in some areas, but keep in mind that due to the patchy attack pattern, landscape level effects will be lower than with mountain pine beetle. Eventually outbreaks will collapse as drought conditions improve and beetles have fewer weak trees to support high populations. In addition, more beetles start dying as they try to survive in healthier hosts.
If you would like assistance with bark beetle identification or ideas for their management, please contact the Washington Department of Natural Resources Forest Health Program at 360-902-1300 or forest_health@dnr.wa.gov.

More work to do on 318th Anniversary of Cascadia quake
It was 318 years ago today when the earth last served Northwesterners a catastrophic reminder that it is always in motion.
On Jan. 26, 1700, the Cascadia subduction zone produced a Magnitude 9 megathrust earthquake that ripped a 1,000 km tear just off the North American coast, shaking and flooding land from British Columbia to California.
Oral traditions from the Quileute and Hoh tribes described the night the Thunderbird and Whale fought, shaking mountains, uprooting trees and covering the land with ocean water.
DNR Geologist Tim Walsh explains to a National Geographic documentary crew how these red cedars were killed by a flood of seawater more than 300 years ago after the Cascadia Subduction Zone magnitude 9 earthquake of 1700.Geologists say the event was the result of the Juan de Fuca tectonic plate pushing under the larger North American plate. The violent subduction resulted in the quake that dropped the coast as much as 6 feet and produced a tsunami that reached almost 1,000 feet inland.
But it was the Cascadia quake’s impacts some 4,700 miles across the Pacific Ocean that allowed scientists to properly date and time the geologic event to around 9 p.m. Jan. 26, 1700.
Records in Japan told of the Orphan Tsunami of 1700. That documented tsunami, combined with analysis of red cedar trunks by scientists like Brian Atwater of the United States Geologic Survey revealed land subsidence and seawater inundation that submerged coastal forests.
What about the next one?
So that’s how we know the damage produced by the last Cascadia quake. But what about the next one? The geologic record shows the Cascadia subduction zone produces megathrust quakes every 300 to 600 years, after all.
The first tip is to be ready. Have plans for what to do when earthquakes or tsunamis happen.
In addition to developing plans to prepare for natural disasters like our friends at Washington Emergency Management advise, you can know more about what these geologic hazards likely mean for your neighborhood, thanks to the hard work of our geologists.
Levels of probable earthquake damage in Washington and Oregon are shown in red, orange and yellow. Image: USGS.DNR holds scenarios developed to show how seismic forces could impact all of Washington’s communities, from Aberdeen to Zillah. One of those scenarios shows the toll another Magnitude 9 Cascadia quake could inflict.
Shades of red indicate the number of buildings that could be damaged in the Grays Harbor area from another M9 Cascadia subduction zone earthquake.
You can view that scenario, and 19 others on our seismic hazard catalog.
More work to do
And although a lot of work has been done to identify and locate areas that could be impacted by earthquakes and tsunamis, there’s a lot more to do.
Washington faces the second highest risk from earthquakes, and one of the highest for tsunamis in the nation, yet remains the only west coast state that does not have an inventory of the seismic hazard for critical infrastructure. In addition, many communities along the coast have either outdated tsunami inundation maps – or no maps at all.
That’s why DNR is asking the legislature this year for a funding package that will allow us to produce a robust set of tsunami inundation maps; inventory critical infrastructure; provide maps and data for emergency responders, city planners and our fellow geologists; and – most importantly – identify, map and mark evacuation routes in communities that might impacted by the next tsunami, whether that’s from a Cascadia subduction event or more remote earthquakes like this week’s M7.9 strike slip quake at the convergence of the Pacific and North American plates southeast of Alaska’s Kodiak Island.
You can find out more about the risks Washington’s active geology present to you and your loved ones with the scenario catalog or by the hundreds of reports on Washington geology filed in the Washington Geology Library. Those reports can also be accessed online through our new publications catalog.

Select the right place to plant your tree: tips to avoid tree-planter’s remorse
Is your yard a bit bare and lacking character? Trees to the rescue!
Early spring is a good time to plant new trees, and now is a good time to plan for them.
Whether you decide to plant a tree for aesthetics, to increase your property value, to save energy through shading, or to provide food and shelter for the birds, it is important to plan for your planting.
The first step is to think critically about where you’d like to plant your tree, The conditions of your desired planting site can help you determine what type of tree might be the most successful in that location, that is assuming your desired location can actually support a tree.
Considerations when evaluating your site include:
- Are there underground utilities? Call 1-800-424-5555 two working days before you dig a hole. A utility location service will mark the pathways of underground utilities on your property, including water, electric, gas and sewer, so you can avoid costly and dangerous line damage.
- Is there enough space for the tree? Visualize the tree 50 years from now and plant so that it will not interfere with nearby structures, or overhead utilities (see photo). A large-statured, long-lived tree will need more space than one that matures at a small height. Only small-growing trees (less than 30’ at maturity) should be planted under overhead power lines. Consider how wide the base of the tree will be at maturity, and plant to avoid damage to sidewalks, and infrastructure.
- What are the environmental conditions? Some trees are tolerant of partial or full shade; others need full sunlight to survive. Some trees tolerate well-drained, dry soils while others need and thrive in consistently moist soils.
- Do you need a permit? Know your community’s regulations regarding tree planting on public and private property.
It might help to take photos and record notes about your site, including distances to buildings, sidewalks, driveways, and utilities. This information will help the staff at your local nursery point you toward a few tree choices that are well-matched to your planting site.

Washington’s kelp forests rely on cool weather and water to thrive
Washington’s kelp forests rely on cool weather and cold water to grow, and are sensitive to changes in climate processes, according to a recent study of the iconic seaweed that grows along the saltwater shorelines of Puget Sound and the outer Pacific coast.
Like coral reefs and rain forests, kelp is a foundation species that supports a unique and diverse community of animals.
That’s why Helen Berry, a scientist with the Washington Department of Natural Resources, teamed up with Dr. Cathy Pfister of the University of Chicago and Dr. Tom Mumford, Marine Agronomics (retired WDNR) to look at the health of kelp forests along Washington’s shores and study the factors that influence their growth or decline.
Photo credit: Cathy PfisterUsing climate data, historical kelp surveys and DNR’s unique 26 year monitoring data set, the research team explored the dynamics of kelp forests along the Strait of Juan de Fuca and the Pacific coast.
The research has just been published in the Journal of Ecology.
Looking through the historic lens
The team’s study found kelp forests were most abundant and persistent along the western Strait of Juan de Fuca and the outer coast, remaining stable when compared to historical kelp surveys done in 1911- 1912. Meanwhile, kelp forests declined in the eastern Strait over that same time. The proximity of kelp forests to human population centers and their distance from the influence of cooler oceanic waters may explain this century-scale decline. Worldwide, kelp dynamics vary greatly – extreme losses were recorded recently in Tasmania and northern California, while other areas show stability or gains.
In contrast to the outer coast and western strait, scientists are concerned about declines in kelp forests within Puget Sound. DNR scientists are currently completing a study that examines changes in South Sound over the last century.
- Abundance and persistence of giant kelp (Macrocystis) and bull kelp (Nereocystis) canopies between 1989 and 2015. The symbol shape depicts species. The size depicts abundance. The color indicates how consistent in abundance each population has been over the last 26 year – more red colors are more consistent through time. (Figure 1 in Journal of Ecology publication.)
Conditions more important than competition
Along Washington’s shoreline, some kelp beds persist over decades, others fluctuate greatly year-to-year. The long-term data set allowed the researchers to detect climate signals in the dynamics of kelp forests. Throughout state waters, kelp cover was strongly related to large scale climate indices. Increased kelp cover occurred when the Pacific Decadal Oscillation and the Oceanic Niño Index were negative and the North Pacific Gyre Oscillation was positive, conditions where seawater is colder and more nitrogen rich.
Macrocystis Photo Credit: Brooke Wiegel Nereocystis Photo Credit: Brooke WiegelThe 2 species that compose kelp beds, the annual bull kelp Nereocystis luetkeana and the perennial giant kelp Macrocystis pyrifera have positively correlated dynamics: a good year for one species is also good for the other. This suggests that environmental conditions are more important than competition between species.
How will kelp forests will be affected as our oceans change?
The climate index correlations showed lower kelp forest abundance during warmer water phases. Additionally, a 93-year temperature record in the region revealed a 0.72-degree Celsius increase over this period. The responsiveness of kelp to climate indices, coupled with increasing temperature and increasing human population, suggests a need for wise management to protect this iconic resource.

Pros and cons of small trees
Small trees have skyrocketed in popularity, most importantly thanks to utility companies. Trees no taller than 25-35 feet will not grow up into overhead power lines, which reduces tree-related outages and the need for heavy pruning to achieve clearance.
Smaller trees require less space above and below ground than larger trees do, which generally (but not always) results in fewer and less severe conflicts with infrastructure. Highly urbanized planting sites are often too cramped for large trees, whereas small trees can more easily be tucked into tight spaces.
Small trees are no less prone to storm damage than larger trees. Yet, shorter trees with small diameter wood are inherently less likely to cause serious harm when they break.
In spring, dogwoods, crabapples, cherries and other small trees push prolific, show-stopping blooms that few shade trees can match.
In spite of these benefits however, there are some serious short-comings to small trees.
Cons
Thanks to ecological adaptations in their native environments, small trees may have short but very wide canopies, multiple stems or trunks, low branching, and irregularly shaped crowns.
These growth forms are generally not appropriate along streets, in parking lots or in commercial districts.
Can you imagine a vine maple in a sidewalk cut out or a parking lot island? You would constantly be hacking up the tree to provide the clearance and visibility you need in those settings.
Small trees are perhaps the worst trees to plant for sign visibility. Pruning up the low branches almost never achieves good line-of-sight with signage, and cutting off the top of the tree…well, we all know how bad that is.
Many small trees, including Cherries, Plums, Pears, Crabapples, Hawthorns and Serviceberries, are susceptible to a battery of insect and disease problems, which can reduce tree health, increase mortality and drive up maintenance costs. Some orchardists are concerned that pests and diseases harbored by ornamentals may inadvertently threaten local fruit crops as well.
Environmentally, small trees are dwarfed by larger ones. A small tree casts less shade, buffers fewer winds and conserves less energy. Small trees also intercept less stormwater, scrub fewer particulates from the air, and capture less carbon than large trees will. The relatively shorter lifespans of most small trees means what benefits they do provide won’t last as long.
A small tree is beautiful in bloom, however, few small trees can achieve such architectural feats as framing and softening the visual appearance of large buildings, delivering the much-coveted tunnel-effect on tree-lined streets or providing a more comfortable sense of human scale in pedestrian areas.
Sometimes a small tree is the best option, such as when power lines are overhead, but small trees aren’t a panacea. Planting the right tree in the right place should always include an analysis of the pros and the cons. And in fact, knowing the cons may be more valuable.
Forest Health & the Hungry Hungry Caterpillar
The life of a Douglas-fir tussock moth is not an easy one. The females can’t fly, and food is often scarce, not to mention viruses that make them explode. What’s more difficult than being a tussock moth, is having those moths in your forest.
Every ten years or so, the tussock moth population skyrockets in some areas of eastern Washington, well beyond what the forest can support. When that happens, these insects can eat so much that they literally kill the fir trees they feed on, sometimes up to 40 percent in a single stand. If a tree is lucky enough to survive the infestation, they’ll then be much more vulnerable to disease, pests and wildfire.
Often when we talk about species that destroy forests, those species are invasive. They didn’t come from the areas they’re killing. The tussock moth is actually a native species here in Washington, so what causes their once-in-ten-year eating rampage? We know that historically, the event happens approximately every ten years, but with a potentially disastrous ecological hazard, being as precise as possible is very important.
The male tussock moth has one goal in life – to mate. The Washington State Department of Natural Resources knows that this is the case, and so we use it to our advantage. Every year, we set out hundreds of traps for the male moths, baited with female pheromones.
One of the goals of the new 20-Year Forest Health Strategic Plan for eastern Washington is to produce and share better forest health data:
Tussock moth tracking is one of the tools that entomologists use to assess forest health. In 2016, the Department of Natural Resources and other agencies placed traps in 260 areas throughout eastern Washington, hoping to gather a large enough sample to measure the general population. With enough traps, we can get a good picture of how many moths are out there, and how many there are likely to be in the near future. A trap in a typical year will catch around two or three moths. But in a year proceeding the “swarm,” the trap will catch upwards of forty moths. If we can predict next year’s population, landowners can better prepare their trees. In a more big-picture sense, however, we can also prioritize which sections of our forests to modify.
The Department of Natural Resources also conducts aerial surveys of eastern Washington forests in cooperation with the U.S. Forest Service. Some of those surveys are looking for what’s called “defoliation” (trees with discolored or fewer leaves and needles). This is an excellent indicator of forest health, and it’s a good way to measure the effects of a tussock moth outbreak. Combined with trapping, we get a good idea for what’s going on across millions of acres of Washington forestlands.
Why are moth population explosions such a hazard to the health of our forests? It’s a native species, so why is there an imbalance?
Historically, wildfires were an important part of the ecosystem. These wildfires would burn through forests on a regular basis and clean the landscape of branches, smaller (less fire resistant) trees, and underbrush. Since western settlers came to this part of the state, those natural fires have been prevented. The result of this has been unnaturally dense parts of the forest with more fir trees, and it is in these dense stands that the Tussock moth thrives and spreads. In natural, spread-out stands of trees, it is much more difficult for the moth to travel and nest.
Washington State Department of Natural Resources entomologist Glenn Kohler shares forest health concerns and demonstrates tracking methods for KOMO TV.This is why the 20-Year Forest Health Strategic Plan: Eastern Washington calls for thinning or treating 1.25 million acres of overstocked forests. The Department of Natural Resources looks to lead statewide efforts to move forests to more resilient conditions. Not only will this help manage moth outbreaks, but it will also make our land much less susceptible to catastrophic wildfire. Through mechanical thinning and prescribed burns, (more on that here) we hope to regain balance and a healthier outlook for the eastern half of the state.
Moth traps and aerial surveys are two methods the Department of Natural Resources can use to help update forest inventory data on a regular basis to reflect changes in forest conditions – including fuel conditions – from insects. One of the plan’s strategies is to, by 2020, have comprehensive maps of current forest structure and fuel conditions available for eastern. The plan also identified several other data needs: wildland-urban interface areas, areas where forest health treatments have occurred and trends in wildfire risk. This data will help us to be efficient and better understand which approaches are most effective.
Monitoring and progress reports will require collaboration and continued support of existing partnerships between the Department of Natural Resources, Department of Fish and Wildlife, USDA Forest Service, Bureau of Land Management, Natural Resource Conservation Service, tribes and private landowners.
Achieving this goal may not be much easier than the life of a Douglas-fir tussock moth. Yet, by working collaboratively, it is possible. Together, we can monitor and track our progress toward healthier, safer forests.

New Year’s resolutions for you and our community’s trees
With a new year starting, many of us will take a hard look at our habits and behaviors and set new goals.
How about investing energy in New Year’s resolutions that make a difference to trees in your community? Completing these resolutions might bring you and your community benefits too.
Suggested tree resolutions for 2018
- Take a child to a local park, forest or natural area with a tree identification book to explore the environment.
- Attend at least one urban forestry event to better understand how your community supports forestry activities.
- Arrange a friendly chat with a local developer, business owner, homeowner association president or other stakeholders in community forestry.
- Write articles, blogs or letters that educate or champion the importance of trees in your community.
- Donate to or volunteer for an organization that supports healthy community trees and forests.
- Plant a new tree every month or the equivalent (12 trees during 2018).
As a tree fan, it is important to remember that trees need to be healthy to provide the many great benefits we expect of them. Trees growing in urban areas need particular care and management throughout their lifetime. Older and larger trees tend to provide the greatest benefits, but they also tend to have more and greater defects that can impact public safety (see Timely Tree Tips in the Tree Link Newsletter for more on this topic). If we do not care for young trees, they will not live to be old trees, and if we do not care for old trees, then we undercut a lifetime of investment in their success.
DNR’s urban forestry staff are available to assist with efforts in your city. Give us a call for ideas on how you can advance the planning, care and management of the trees in your community.

Taking Kindling From the Forests to the Classroom for Forest Health
New Building Materials
This video is remarkable. First of all the speed with which they’re building this elementary school classroom is incredible. In one day, they have most of the structure in place. Second, they’re helping to prevent catastrophic northwest wildfires while they do it.
The secret is in the pre-assembled panels they’re using. Local cross-laminated timber technology is one of many new possibilities outlined in Washington’s 20-Year Forest Health Strategic Plan. Yet, what does building gorgeous new classrooms for kids have to do with wildfires?
The Problem
If you’ve been following the news, you may have noticed the increasing severity of the wildfires around our state. In 2014 and 2015 we had two consecutive years of record-breaking wildfires.
Why are the fires getting worse? Part of the problem is densely wooded land. Fire is a natural, important part of the ecosystem in many of our eastern forests. However, past forest and wildfire management practices have resulted in uncharacteristically overstocked and crowded forests. Too much vulnerable underbrush. Too many skinny, small-diameter trees competing for water, nutrients and sunlight. Fires in these densely packed forests often burn with uncharacteristic severity and duration.
Think of it, if you will, as removing kindling from a fire.
When you’re building a fire, you can’t get it burning if you start with the big logs. You need to surround those logs with smaller branches before it really gets going. Wildfires in the forest work in much the same way. If there are enough branches and vegetation to act as kindling, a fire can quickly ignite the big trees and grow out of control. Take away the smaller-sized and dense vegetation, though, and the fire stays along the ground and leaves most of the big trees unscathed – maybe even improved. This is why the new forest health strategic plan for eastern Washington calls for increased amounts of mechanical thinning – so when wildfires begin, they will be more manageable, less severe, and cause little damage to larger, older trees.
See how The Nature Conservancy is using mechanical thinning treatments to reduce fuel in the Cascades.One of the obstacles to removing small-diameter wood and brush has been that it may not pay for itself in the way that traditional logging does. Up until recently, mills haven’t had the technology to produce useful products from an excess of smaller wood.
As part of its project to build the classrooms seen above, the state had to use Oregon-manufactured cross-laminated timber. But imagine the impact of being able to produce our own cross-laminated timber here in Washington. Imagine the boost to our rural economies. Imagine urban construction sustainability benefits. Your imaginings may become reality. Two cross-laminated timber manufactuers are slated to open in eastern Washington in 2018.
(Use photo of Hilary at Seattle unveiling. Caption: Commissioner Franz admires a Seattle classroom, a cross-laminated timber demonstration project designed to spur demand.
It’s the promise of solutions like this that drives one of the key goals in the new 20-Year Forest Health Strategic Plan: Eastern Washington:
The plan, just released by Public Lands Commissioner Hilary Franz and the Washington State Department of Natural Resources that she leads, points to how forest health, wildfire risk, and rural economic development are inextricably linked in eastern Washington. Oregon produced a cost-benefit study in 2012 indicating that for every $1 million spent on forest restoration, there is approximately $5.7 million in economic benefit and return.
Well-managed, resilient forest ecosystems can provide natural resource jobs, recreation jobs, and timber products. The 33 agencies and organizations that collaborated with the Department to create the plan emphasized that cross-laminated timber and other emerging technologies can help build Washington’s economy.
The Solutions
Using locally-sourced, renewable materials would mean that our buildings are made sustainably, and responsibly. And of course, not importing our wood from far away states, (or Canada) means that we’re cutting down on harmful emissions. To that end, the organizations who collaborated on the forest health plan proposed a “local wood” marketing campaign, to emphasize the importance of buying locally. Often, when we hear someone telling us to buy local, it’s in the context of food. But it is equally important to keep our timber supply close to home.
Part of the plan to support local economies, is to increase the amount of timber that’s selectively harvested from overstocked forests. Not only does this help the health of our forests, (removing competition so trees can grow large and resilient) but the generated revenue can help cover the cost of some of our other long-term treatment options. Logging and forest products infrastructure are needed to support many of the treatment plans, which can help keep local mills in business too.
We can also help realize this goal by supporting wood energy systems at appropriate and meaningful scales, such as support for the Washington Department of Ecology’s Wood Stove Change-Out Program to get outdated stoves replaced with clean-burning wood and pellet stoves. Pellet stoves burn compressed wood to create source heat for residential and sometimes industrial spaces. Today’s systems, fueled with renewable wood pellets, can reach an efficiency factor of more than 90 percent. Expanded use of such technologies can improve air quality, provide another market for forest restoration by-products and stimulate local economic development.

Eastern Washington’s 20-Year Forest Health Strategic Plan and the Jolly Mountain Fire: A Retrospective Look at Efforts to Reduce Risk
A mile long and 200 yards wide. Just this spring Washington State Department of Natural Resources forestry staff installed the Lick Creek shaded fuel break in the Teanaway Community Forest between densely overgrown forestlands to the north and the Wagon Wheel community and Teanaway Valley to the south. It would play a critical role just a few weeks after its completion when, on August 11, 2017, lighting give rise to the Jolly
The Jolly Mountain Fire as it approached Teanaway Valley outside of Cle Elum in August of 2017.Mountain Fire.
Predictions say that compared to last century we can expect to see four times more acres per year burned later this century. Washington will continue to see wildfires. Yet, strategically focused forest health treatments, particularly around neighborhoods, can reduce uncharacteristic, high-severity wildfires, increase forest resilience and reduce damage. That’s why Public Lands Commissioner Hilary S. Franz and the Washington State Department of Natural Resources are promoting Washington’s new 20-Year Forest Health Strategic Plan for eastern Washington. It identifies reducing the risk of wildfire in populated areas as a key goal.
As the Jolly Mountain Fire grew, it ultimately became the nation’s second-highest priority. This meant that fire responders were able to get good access to limited resources. Eventually up to 828 personnel were assigned to the fire. With this support, wildland firefighters were able to work on fire line operations while contractors worked to prepare structures by removing vegetation with brush chippers and chainsaws. As the fire approached, structure firefighters from across the state arrived in time to provide backup protection to area homes. This allowed wildland firefighters to focus their efforts on managing the fire itself. This isn’t always the case.
Wildland firefighters are often diverted from their work to stop an advancing fire to instead focus on defensive tactics designed to protect lives and structures. This can reduce their effectiveness, increase the effort’s complexity and result in more expensive suppression costs. The cost of the Jolly Mountain Fire has reached about $25 million – and expenses are still being tallied.
Last summer’s Jolly Mountain Fire threatened many populated areas. But one, the Wagon Wheel community, had a couple things going in its favor.
Wagon Wheel became a Fire Wise USA community in 2010. Though the 51 homeowners at one time had invested $96,000 toward reducing their wildfire risk, diligence varied over the years. As the Jolly Mountain Fire began to look like a threat to this community, firefighters had time to assess how well they would be able to defend each home. One lot with dense vegetation can pose a serious risk to surrounding properties. If that home and nearby trees catch fire, countless sparks will cascade down upon neighboring homes. It became clear that more work would have to be done in Wagon Wheel.
One of the strategies within the new forest health strategic plan is to better support landowner assistance programs that help reduce risk – such as creating Community Wildfire Protection Plans and defensible space around homes. Firewise USA is such a program. Last year Firewise USA saw more new communities join from Washington than any other state. Yet, communities have to maintain vigilance and repeatedly address ever-growing vegetation.
At the same time, Washington population is ever-growing too. Development is
A wildland–urban interface (WUI) is where houses meet or intermingle with undeveloped wildlands. WUI areas are ripe for human-environment conflict, such as wildfire damage, habitat fragmentation, introduction of exotic species and declining biodiversity.fragmenting Washington forests and new homes built in wildland areas increases risk.
Retroactively, one might acknowledge that the Teanaway Valley is a difficult place for a neighborhood. The 20-Year Forest Health Strategic Plan: Eastern Washington itself recognizes this particular watershed as one of the many higher priority areas across the state due, in part, to its fire risk.
Forty years ago, when home construction began here, our climate was not changing the way it is today and people were less aware that developing in wild areas like this would increase wildfire suppression challenges. Our state has learned hard lessons since then.
The new 20-Year Forest Health Strategic Plan for eastern Washington calls for ways to keep forestlands for converting to non-forest uses – such as subdivision development in wildland-urban interface areas. In fact, one of the motivating factors for purchasing the Teanaway Community Forest, which surrounds the Wagon Wheel community, was to prevent further encroachment into these forestlands. But you can’t turn back the clock and plenty of Washington communities just like Wagon Wheel already exist.
To reduce risks to these many existing communities the forest health strategic plan proposes more mechanical treatments and controlled burns in wildland-urban interface areas. This brings us to the second thing that the Wagon Wheel community had going for it.
The state has not owned nor managed the Teanaway Community Forest for long – the legislature purchased it in 2013 – and there are many competing funding needs. However, the Tenaway Community Forest Advisory Committee concurred with staff from DNR and WDFW that completing the $185,000 Lick Creek shaded fuel break was a high priority. They recognized that this fuel break could help protect the state’s $100-million community forest investment, important wildlife habitat, nearby communities and critical waterways – nearly 400 miles of free-flowing streams and rivers crisscross the area and form the Teanaway River.
The Lick Creek mechanical thinning project followed along the Lick Creek Tie Rd. and other old roadbeds. These roads provided good access for machinery to trim low-hanging branches and cut back brush. Crews left larger trees in clumps and gaps resembling the kinds of tree stands historically found in this watershed. The road itself was expected to serve as a fuel break in the event of a wildfire – as it did on September 2, 2017.
As the fire initially grew, firefighters had come through the shaded fuel break and decided that they would attempt to stop this edge of the fire’s progression here. The reduced fuel levels would lessen the intensity of the fire and it was the first place where they would be able to safely position firefighters. In additions, those roads could provide a means of escape. Crews then cleaned up areas in need of additional attention and extended the fuel break miles in either direction.
Along the northern end of the Lick Creek shaded fuel break as crews used back-burns to meet the Jolly Mountain Fire.Over several nights firefighters back burned into the fire. (The strategy was to light the back-burns as ambient temperatures lowered and humidity recovered slightly – to reduce the intensity of the back-burns.) Conditions were challenging – nearly record breaking heat and dryness. Today you can see evidence of multiple places where firefighters had to put out fire that “slopped” or “spotted” across the line.
Shaded fuel breaks, Fire Wise preparedness, fuel reduction projects and forest health treatments offer no guarantees. Had the wind blown differently, this may have been a very different story. For Commissioner Franz, the near-miss was emotional experience.
“The tension we all shared was just incredible – I could feel it in the air,” said Franz. “We knew we were all doing everything we could, but we also know that it was very serious situation. My heart was just aching for what these communities were having to endure.”
Fortunatley, this time, the line held. About 10 percent of the Teanaway Community Forest was severely damaged, but no structures or lives were lost.
Today, plants in the less severely burned areas are returning. The tall trees – and even a few of the smaller ones – have survived. But there is more work to do.
A full expression of the 20-Year Forest Health Strategic Plan: Eastern Washington across this landscape would have forest health treatments extend through the entire watershed, rather than cut through as a single line. Under this plan’s vision, you would see treatments extended past property lines so that Teanaway Community Forest, Natural Resources trust lands, Wagon Wheel private properties, U.S. Forest Service, Nature Conservancy, and other neighboring forestlands are equally resilient and prepared.
The fire would not have had to be stopped at any specific point, such as the Lick Creek fuel break, but could have been addressed anywhere within the forest based on other relevant considerations – safety, threatened species wildlife habitat, proximity to homes, risk to infrastructure, or even operational expenses.
Ambitious? Yes. Will it take time? Yes. Yet Commissioner Franz believes she, her
Hilary Franz, Washington State Commissioner of Public Lands.Department, and all of Washington, are up to the task.
“We’re motivated. Everyone understands the issue and people are beginning to understand that we have a strong start to a solution,” said Franz. “As we successfully implement such efforts, our state and communities will begin to benefit from reduced high-severity wildfires.”
