Growing Healthy Forests Throughout Washington
- Forest Health Hazard Warning
- Forest Stewardship Program
- Urban and Community Forestry Program
- Cost-Share Programs
- Washington State University Extension
DNR works with local fire districts, conservation districts, counties, and extension programs to help Washington residents benefit from the Firewise Communities/USA. Administered through the National Fire Protection Association, the Firewise Program encourages homeowners and communities to prepare for wildfire.
Former Commissioner Goldmark issued a Forest Health Hazard Warning for portions of Ferry, Klickitat, Okanogan, and Yakima counties under the authority of Washington State Law RCW76.06 to notify residents of forest threats and prompt action to mitigate those risks.
The Forest Stewardship Program provides land management advice and assistance to forest owners. The program helps assess resource conditions and forest health, identify problems and opportunities, and identify management practices to achieve objectives. The program is administered by the Small Forest Landowner Office.
The Urban and Community Forestry Program provides technical, educational and financial assistance to Washington’s cities and towns, counties, tribal governments, non-profit organizations, and educational institutions. The UCF program seeks to educate citizens and decision-makers about the economic, environmental, social and aesthetic benefits that healthy community trees provide. The program's mission is to help communities develop self-sustaining urban forestry programs that enhance the health and functionality of urban trees and forests to maximize those benefits.
Information and applications for DNR administered cost share programs to reduce wildfire risk can also be found on the Forest Stewardship Program site. Other programs through the Forest Stewardship Program are available to provide assistance with activities such as stewardship plan creation and implementing conservation practices.
Washington State University Extension Forestry provides education and information about forest management to forest owners. The extension offers classes, workshops, field days, and publications. Additional forestry resources - such as coached planning sessions, publications, and videos - can be found at the WSU Extension website.

Climate Change and Forest Health
- If climate change results in more frequent and intense droughts we can expect to see more mortality from insect outbreaks and root diseases due to increased tree stress. However, these pests will still require their range of suitable hosts to maintain outbreaks.
- In a warmer climate, insects can reduce their development time. For some bark beetle species, this may shorten the length of generation time or allow them to occupy ranges farther north in latitude or at higher elevations. In recent years, mountain pine beetle has been documented killing pines outside of its historic range in northern Canada. For some defoliators, the outcome of shorter development time may be more uncertain because they rely heavily on synchrony in time with their hosts.
- Unseasonable extremes in temperatures can effect forest insects, but in various ways. Warmer winters could lead to greater survival of some bark beetles, with the greatest effect at higher latitudes and elevations where extreme cold has excluded them in the past. Early spring warmups could influence some insects to emerge out of synchrony with their hosts or expose larval stage defoliators to late freeze events. Sustained temperatures above or below an insect’s developmental thresholds may slow activity and delay development, possibly exposing them to natural controls longer.

State Lands Forest Health
The State Lands Strategy identifies key values, goals, and objectives that will guide DNR’s forest health program to success. This strategy will help inform operational and tactical decision-making through implementation and prioritization of forest health treatments on State Lands. The goal of this strategy is to create and maintain a landscape of healthy and resilient forested State Lands that supports the trust beneficiaries, the public, and a sustainable forest products market.
Wood Energy and Biomass Utilization
- Serving on the advisory committee of the Northwest Advances Renewables Alliance (NARA), which completed a demonstration flight in November, 2016, with Alaska Airlines using jet fuel made from slash piles.
- WA State Forest Biomass Coordination Group, coordinated by the DNR, WA Dept. of Commerce and WSU Extension Energy Program, provides an opportunity for all stakeholders to collaborate, share information and provide guidance for forest biomass and wood energy efforts in the state.
- $1.35 million in grants from the USDA Forest Service have been given to the DNR for work on wood energy and biomass utilization projects.

Aerial Survey Information
Survey of Personnel Involved in the Cooperative Collection and Use of Aerial Detection Survey (ADS) Data
This important multiagency survey is being conducted by the Aerial Survey Working Group (ASWG) for the purpose of Evaluating Services and Products from Forest Health Protection (FHP). The survey is open from Sept. 1 through Oct. 15.
The following are encouraged to participate in the survey: personnel involved with aerial survey data collection and use including resource managers, silviculturists, planners, pesticide use coordinators, foresters/entomologists/pathologists, technical experts and other users and partners including tribes, academics and nongovernmental consumers of FHP products and services. To participate, please follow this link: https://www.surveymonkey.com/r/ZDD8WWB. Thank you in advance for taking time to share your needs and opinions.
Systematic aerial surveys are conducted to collect and report on forest insects, diseases, and other disturbances across federal, state, tribal and private lands. These surveys have been conducted annually since 1947 in the Pacific Northwest by USDA Forest Service (USFS) with the cooperation of State and private partners since 1948. Aerial surveys have proven to be an efficient and economical way to detect and monitor forest change events over large forested areas. Statewide aerial surveys are conducted each year to assess forest health in Washington State. They capture mortality and discoloration caused by insects, diseases and abiotic disturbances. This relatively low cost remote sensing method gives a coarse, landscape-level overview of forest conditions. The data collected are then used with other remote sensing and ground sampling techniques to further enhance the data accuracy of significant forest health events and changes.
An interactive web service for the Forest Health Aerial Survey data can be here. This is the place where the most current Annual and Cumulative Aerial Survey data are displayed. Users can create their own PDF, JPG, and PNG maps of the field of view by clicking on the printer icon in the upper right corner. Note: The Cumulative Aerial Survey data set contains several million polygons, so to speed up the loading process, the user may want to zoom in until “15 Year Mortality Indicator 2001-2015” title on the left switches from grey to black.
