The foundation of the recovery strategy for the Northern Spotted Owl is a network of owl conservation areas located on Federal lands, complemented by state, private and tribal lands. Use this interactive map to learn about the conservation efforts of the Northern Spotted Owl in Washington State and how landowners have been actively developing management plans to help conserve the Northern Spotted Owl. This special feature shows who manages the forestlands, where the spotted owls live, and how the spotted owls are protected across the landscape.

The Northern Spotted Owl was listed as “threatened” under the Endangered Species Act in 1990 due to over-harvesting of old growth habitat, and lack of regulations to stop the decline. On April 13, 1994, the Federal government adopted President Clinton’s Northwest Forest Plan (NWFP) as a strategy to recovery the owl, which sought to conserve the species on 24.5 million acres of Federal lands over 100 years’ time. The NW Forest Plan is not a “stand-alone” management plan. It amended 26 land and resource management plans (LRMPs) of the U.S. Forest Service and Bureau of Land Management (BLM), marking the first time that the Forest Service and BLM have worked together to preserve ecosystems across their boundaries. The NW Forest Plan developed a forest management strategy to protect more than 1,000 late-successional and old-growth dependent species across 19 National Forests and 7 Bureau of Land Management Districts throughout the three state range of the owl in Washington, Oregon and California. The NWFP established a system of late-successional forest and riparian reserves that would, in conjunction with Administratively withdrawn and Congressionally reserved areas, provide the foundation of protected “old growth” habitat that would benefit spotted owls, marbled murrelets, salmon and many other old growth associated species. Future timber harvesting activities on Federal lands within the range of the northern spotted owl were expected to occur primarily in Adaptive Management Areas and Federal lands determined to constitute the “matrix.” Scientists thought it could take up to 50 years to recover the owl.
The Northwest Forest Plan has been working at slowing the “precipitous decline” of the spotted owl. The Wildlife Society states that this strongly suggests that the recovery plan should continue to be based on the NWFP. The #1 success of the Northwest Forest Plan is protection of old growth habitat. In the first ten years of the plan, older forest on federally managed land appears to have met or exceeded the Northwest Forest Plan expectations of growing 600,000 acres per decade. In the first ten years of the plan, older forest grew twice the rate, at 1.2-1.5 million acres, outpacing losses from all sources. Since 1994, federal timber harvest levels have been reduced 98% in Washington State and 80% across the three-state range.
On the other hand, the NWFP has not been fully implemented as it was envisioned. Lack of active management in the adaptive management areas has caused serious setbacks in learning about the spotted owl’s use of prey and barred owl-spotted owl interactions. The plan reduced harvest levels by 80% and only a third of the new harvest level has ever been achieved. This resulted in a range-wide harvest reduction of 94%. Other factors that have increased the risk to spotted owl recovery include, lack of active management of fire-frequent, insect prone sites proscribed by the NWFP. Scientific review has shown that failure to fully implement the Northwest Forest Plan on federal lands has increased the risk to spotted owl recovery.
While close cousins, one of the differences between the Barred Owl and Northern Spotted Owl are the number of notes in their calls. The barred owl typically has an 8-note hoot, and Northern Spotted Owl, has a 4-note hoot. If they breed, the Sparred Owl (Barred Owl / Spotted Owl hybrid) has a distinctive 5-6 note hoot.
Recently, scientists say the larger and more aggressive Barred Owl is the most important threat currently facing the Northern Spotted Owl. The range of the Barred Owl now completely overlaps and extends beyond that of the Northern Spotted Owl. The presence of the Barred Owl negatively affects the spotted owl by competing for prey and habitat. Significant effects on reproduction, survival, displacement from nest sites, and the likelihood that spotted owls will not call or hoot during standard survey methods, is making it difficult to detect whether spotted owls are actually there. In the Olympic National Park, barred owls have taken over nearly two-thirds of the spotted owl sites. The Barred Owl range and numbers are expanding rapidly, moving west from the eastern United States, through Canada, and now into the Pacific Northwest. This cousin species lives in similar types of habitat as the spotted owl and eats the same type of prey. Barred Owls are also less susceptible to diseases such as West Nile Virus, and have been known to attack the spotted owl. The USFWS is now conducting sophisticated modeling to analyze various habitat networks across the range, including the barred owl impact. Early modeling results show the spotted owl will not recovery in 10 of the 11 modeling areas without addressing the barred owl invasion, despite the amount of habitat set aside. The USFWS acknowledges that securing habitat alone will not recover the spotted owl and the barred owl threat requires immediate action.
At first glance, the hybrid resembles both the spotted owl, a threatened species that primarily inhabits older forests of the Northwest, and the barred owl, a cousin common to much of North America.
On closer inspection, however, the sparred owl exhibits physical markings, calls and other characteristics that combine the traits of the two parent species.
‘The tail feathers are like a barred owl and the breast feathers are like a spotted owl. The characteristics are intermediate,’ said Eric Forsman, a research biologist for the U.S. Forest Service in Corvallis, Ore.
Both hybrids were males found roosting with female barred owls. The first, originally thought to be a spotted owl, was identified as a cross-breed last month near Mount Baker in the northern Cascades range of Washington.

Every individual owl is protected from harm under the Endangered Species Act.
Federal lands play the primary role in achieving recovery of the spotted owl. The NW Forest Plan serves as the basis for federal forest management. The NWFP explicitly acknowledges that nonfederal lands are not guided by the Plan’s federal standard and guidelines, it encourages agencies to work with nonfederal landowners to seek voluntary contributions to owl conservation through mechanisms such as Habitat Conservation Plans, 4(d) Rules, and Safe Harbor agreements. Washington State’s comprehensive forest practices regulations complement the federal vision for recovery of the spotted owl, implementing a rule developed in collaboration with environmental groups, federal, state and county officials, and forest landowners. In fact, the state’s forest practices rules far exceed the federal expectations for nonfederal contribution to owl conservation. See how spotted owls are protected in the interactive map of Washington State.
In June 2023, the Forest Service established a Federal Advisory Committee (FAC) of 22 private citizens, including representatives from the forest industry, to develop recommendations for amending the Northwest Forest Plan (NWFP). From September 2023 to April 2024, the Committee explored topics like Tribal Inclusion, Economic Opportunities, Fire Resilience, Climate Impacts, and Forest Stewardship. Key recommendations include conserving unprotected old forests, promoting ecological forestry, accelerating restoration in dry forests, and supporting Tribal cultural uses. The recommendations were presented to USDA Secretary Tom Vilsack and Forest Service Chief Randy Moore in July 2024, with hopes to influence the NWFP’s amendment by winter 2024-2025, potentially increasing timber supply and management opportunities across the Pacific Northwest.

The NSOIT focused on several key conservation actions. These included coordinating with federal agencies on Barred Owl control experiments, developing voluntary incentive programs for landowners to engage in Northern Spotted Owl conservation, and promoting outreach to landowners with critical owl habitats. The team also convened a technical group to assess the spatial and temporal allocation of conservation efforts on nonfederal lands using the best available science. Additionally, the NSOIT supported pilot projects for forest thinning to enhance owl habitat and explored innovative conservation funding mechanisms, such as conservation banks, easements, and federal assurances for landowners.
The NSOIT made progress in advancing Northern Spotted Owl conservation. The team successfully developed incentive-based recommendations for landowners and secured participation from various stakeholders in voluntary conservation efforts. The NSOIT played a critical role in promoting research and pilot projects aimed at improving owl habitat, despite challenges in securing consistent funding. Key achievements include progress on Barred Owl control experiments, ongoing technical assessments of conservation scenarios, and collaborative efforts with federal, state, and private partners. The efforts of the NSOIT to create incentives for voluntary conservation manifested in teh 2023 legislative session, where the Governor signed SB 5390 into law July 23, 2023, authorizing the state Dept. of Natural Resouces to enter into a voluntary opt-in Programmatic Safe Harbor Agreement with the U.S. Fish and Wildlife Service to enhance the conservation of northern spotted owl habitat.
