About Oregon's state forests

ODF manages approximately 745,000 acres of forestlands across Oregon. These state forestlands are actively managed under forest management plans to provide economic, environmental, and social benefits to Oregonians. Timber sales on these forests produce jobs and revenue that funds counties, local districts, and schools throughout the state. These forests also offer recreation and educational opportunities, and provide essential wildlife habitat and clean water.

ODF is currently developing a Habitat Conservation Plan and companion Forest Management Plan for about 640,000 acres of ODF-managed forests west of the Cascades. Visit those pages to learn more about these processes and how you can stay informed and involved.

State forests

Before the 1930s, nearly all of the land that is today part of the Clatsop State Forest was in private ownership. Logging camps, railroads, and lumber mills were prevalent in Clatsop County due to the demand for lumber during World War I.

As tracts of timber were cut, the logged land were given to the counties in exchange for paying taxes. In 1936, Clatsop County became the first county in Oregon to deed its forestlands to the state to manage in exchange for part of the revenue generated from timber sales.

The Forest Acquisition Act, passed in 1939, further encouraged counties to deed the foreclosed lands to the Oregon Department of Forestry, giving rise to the state forest system we have today. By 1957, Clatsop County had transferred 141,000 acres to the state.

In 1973, the Oregon Board of Forestry formally dedicated 154,000 acres of forestland as the Clatsop State Forest. Today, the forest provides timber products important to local economies, wildlife habitat, and a place for people to enjoy.​

Nestled in the Coast Range, the Tillamook State Forest sits in the northwest corner of Oregon, between Portland and the coast. Whatever your interest, the Tillamook State forest holds an abundance of opportunities for discovery, exploration, and learning.

The Tillamook State Forest encompasses the same area as the historic Tillamook Burn, the series of large fires that began in 1933 and struck at six-year intervals through 1951, burning a combined total of 355,000 acres. The fires had profound environmental, economic and social repercussions for the coastal counties of northwest Oregon.

In the years since the fires, foresters, professional tree planters and volunteers have worked to reestablish the forest and its many resources. Oregon voters passed a constitutional amendment in 1948 authorizing $12 million in bonds to rehabilitate the land. In total, helping hands planted 72 million seedlings giving the burned-over landscape a new start. The Tillamook Burn was officially renamed the Tillamook State Forest by Oregon Governor Tom McCall on July 18, 1973.​

Today, this hand-made forest is a healthy, productive, and sustainable ecosystem that provides a full range of social, economic and environmental benefits to Oregonians. The forest is managed by the Oregon Department of Forestry out of two district offices, one in Forest Grove and one in Tillamook, with an additional field office in Columbia City. The Tillamook Forest Center offers fascinating exhibits, outdoor trails, progr​ams for families and students, along with recreational information for forest visitors.

Private timber companies harvested most of the forest in the Santiam Canyon between 1880 and 1930. By the 1930’s and 1940’s with the land either logged over or burned by wildfire, many of the timber companies which owned the land saw little value in the forest. Many landowners let their land return to the counties for delinquent taxes while others sold it to the county for a minimal amount. The Forest Acquisition Act, passed in 1939, encouraged counties to deed the foreclosed lands to the Oregon Department of Forestry in exchange for a share of future timber harvest revenues. 

By the time the state took ownership, much of the forest already was naturally restocked with a native mix of seedlings. The only part of the Santiam State Forest that was planted by the Department of Forestry was the area burned by the 1951 Sardine Creek Fire, which burned approximately 21,400 acres northeast of Mehama. ​

Today, the forest is divided into several large blocks of land and numerous smaller parcels along Highway 22, approximately 20 miles from Salem. The Santiam State Forest encompasses more than 47,000 acres in the foothills of the Cascades, and is managed by the North Cascade District, within three counties: Clackamas, Marion, and Linn. ​​​​

About 16,000 acres of the Santiam was damaged in the 2020 Labor Day fires, and some of these areas are re-opening as safety hazards are cleared and, in limited areas, post-fire harvest has occurred. Learn about damage to the forest, restoration plans, and status of popular recreation sites.

The Gilchrist State Forest is Oregon's newest state forest. Formally dedicated in 2010, the forest consists of more than 72,000 acres located in northern Klamath County about 35 miles south of Bend near the communities of Gilchrist and Crescent.  

The Gilchrist forest tract, and the town of Gilchrist, was established in 1938. The current Gilchrist State Forest was part of larger timber holdings owned by the Gilchrist Timber Company for most of the 20th century. The community of Gilchrist was among Oregon’s last operating “company towns,” serving as the site of the company sawmill and home to many of its workers.  

The Gilchrist family sold the property and mill in 1991 to Crown Pacific, which liquidated the forest to pay debt and eventually entered bankruptcy in 2003. The land, which once supported expanses of large Ponderosa pine trees, was heavily harvested in the early 1990s, following the Gilchrist Timber Company sale. The area was replanted as required by Oregon’s Forest Practices Act; as a result, most of the trees in the Gilchrist forest are about 20 years old. 

The State of Oregon purchased the property in March 2010 from Fidelity National Timber Resources, which had owned it since 2006. The purchase was financed by bond sales, to be repaid over 20 years using proceeds from the Oregon Lottery. ​​

Formally dedicated in 1979, the Sun Pass State Forest is located in Klamath County approximately 90 miles north of Klamath Falls and just southeast of Crater Lake National Park. This 21,300-acre state forest is comprised of beautiful pine and fir forests and mountain meadows, and is managed by ODF's Klamath-Lake District. 

The State of Oregon purchased the original 14,450 acres of Sun Pass State Forest from Yawkey, Woodson, Ourbacker, and Algoma Lumber Company in 1943. In 1944, Klamath County deeded an additional 480 acres to the Board of Forestry to expand the Sun Pass unit. In 1947 and 1948, the Oregon Board of Forestry bought two more parcels of private land which were added to Sun Pass. In the 1970s and 1980s, the State of Oregon and the Winema National Forest (now the Fremont-Winema National Forests) agreed on a series of forest land exchanges to expand the contiguous area of Sun Pass. The state gave up a number of small outlying parcels in exchange for 4,401 acres of United States Forest Service land adjacent to the main area of Sun Pass. These exchanges completed the expansion and consolidation of Sun Pass State Forest.​​

ODF also owns and manages other smaller parcels of forestland on the West Oregon, Western Lane, and Southwest Oregon districts, located primarily in the Coast Range near Corvallis, Eugene and south to the California border. These forestlands are managed for a range of benefits and values -- which by statute we call "Greatest Permanent Value" -- including economic, environmental and social benefits.​

Management & planning

​​​State forests contain many resources such as streams, recreation sites, and unique wildlife habitat that are managed and protected under state forests’ policies and forest management plans. These areas are highlighted through the “Forestland Management Classification System” (OAR 629-035-0055​) adopted by the Board of Forestry in 1998 to ensure a range of benefits would result from an area’s management emphasis. The current FLMCS has been applied to approximately 800,000 acres of state forestland through four land management classifications, which include:

  1. High value conservation areas: A​reas managed specifically for conservation, emphasizing protection of old growth trees, endangered species and habitat, rare plants, and water quality, among other emphases. HVCAs comprise approximately 120,000 acres of total state forestland.

  2. Special use areas: Areas managed for heritage sites and cultural resources, utility rights of way, and rock quarries, among others. Special use areas comprise nearly 80,000 acres of total state forestland.

  3. Focused stewardship: Forestland managed for a specific purpose or resource, including recreation, streams and rivers, steep slope areas, and timber production, among other uses. Focused stewardship areas approximately 510,000 acres of state forestland.

  4. General stewardship: Forestland that does not fit into one of the other three categories and can be managed for a variety of emphases. General stewardship areas more than 150,000 acres of total state forestland.

The land classifications can overlap, so an area classified because it is a recreation site, may also be classified because it is a riparian zone and it contains a heritage site. Land classification areas receive a complete evaluation during each major revision of ODF district implementation plans. In addition, interim changes can be made to FLMCS through District Annual Operations Plans.

Please note that this state forest classification system is different from the forestland classification process related to wildfire risk in the urban interface that conducted by the Fire Protection Program.

​Long-range forest management plans provides overall direction for managing the state forests in the planning area. It takes a broad, integrated resource management approach to planning. These plans presents goals and strategies for managing resources found on state forest lands. Further, it advances a specific set of strategies designed to integrate the management of several key resources (timber, fish and wildlife, and forest health). It is based on the premise that these are not mutually exclusive resources that must be traded off against each other; these are interrelated resources that can be managed in an integrated manner to achieve multiple benefits.​

Each district in the planning area develops an implementation plan, which describes in more detail how the management strategies described in the forest management plan will be applied on that district. These plans describe forest management activities such as timber harvest, road construction and maintenance, reforestation and young stand management, recreation, aquatic habitat restoration, and protection strategies for species of concern. These plans will be revised at least every ten years or sooner, if new technical information or changing conditions may call for updates to individual district implementation plans.

Implementation Plan (IP) Revisions for the Astoria, Forest Grove, North Cascade, Tillamook, West Oregon, and Western Lane District (Southwest and Veneta Units) were recently approved through June 30, 2025. These approved Implementation Plans can be found below.

ODF held a 30-day public comment period from Feb. 3, 2023 through March 6, 2023 and a public information workshop was held on Feb. 2. Below is a link to the information workshop presentation and a summary of comments and responses:​

​Approved Implementation Plans:

​​​​​​​​​​​​​​​Each district prepares annual operations plans that are designed to achieve the goals and objectives identified in the district implementation plans. These annual plans show the location and nature of forest management activities and projects that are proposed for a given fiscal year and are the most detailed level of planning conducted by the Oregon Department of Forestry.

State forests by law must provide economic, environmental and social benefits to Oregonians. To achieve the legal mandate, these lands are managed to create healthy productive forests, high-quality habitat for native fish and wildlife, clean water, benefits and revenues to rural communities and timber-related economies, as well as recreation and educational opportunities. Overall management policies and management goals are established in long-range Forest Management Plans and Implementation Plans (which are available via the links above). Annual Operations Plans describe activities to achieve the policies and goals laid out in the longer-range plans.

Common topics included in an Annual Operations Plan include:

  • Timber harvest operations
  • Recreation improvement and maintenance projects
  • Forest road construction, maintenance, and improvements
  • Reforestation/replanting and young stand management activities
  • Habitat improvement for native species
  • Invasive species management

ODF accepted public comment on proposed fiscal year Annual Operations Plans for Fiscal Year 2025 for 45 days starting April 3. The agency received 1,061 written comments. Each comment received was reviewed and the feedback considered through the lens of aligning with State Forests current plans and policies. Comments received that resulted in edits to specific timber sales that are detailed in each of the district Summary Documents. 

In addition to the sale specific updates, the following is a high-level summary of the comments received highlighting the major themes, topics, and the agency responses. 

Conservation & restoration

State forests are managed to produce sustainable harvests to maintain forest health, develop habitat and generate predictable revenue. 

On westside forests, a technical approach called structure based management is being used.  Structure-based management uses harvesting techniques – thinnings and well-planned clearcuts – to help forests more quickly evolve into older stages. This type of active management accelerates the natural maturing process of a forest. Structure is trees, both small and large, standing dead trees (snags), down wood (decaying logs) and other vegetation such as shrubs. All these components are important to wildlife. 

Most of the Eastern Oregon Region’s state forests have an “uneven-aged” structure with trees of many species, sizes and ages. Selective harvesting is used to maintain or improve uneven-aged stand structure. The harvesting reduces the density of the stand, alters tree types and creates openings for new seedlings. It favors healthy trees of desirable species. Uneven-aged management results in high timber production, a visually pleasing forest cover, lower reforestation costs, and a biodiversity of wildlife habitat. ​​

​​State forest management plans (FMPs) include an Aquatic and Riparian Strategy for implementing habitat restoration projects. The FMPs establish several principles that guide habitat restoration activities and priorities. Restoration projects are tracked regularly and accomplish​ments are reported below.

All state forests

Watershed analysis is another landscape strategy and a key piece in determining current conditions of riparian and aquatic habitats and in guiding management to address limiting factors. ODF conducts watershed analysis projects in five watersheds containing large percentages of state forest land. These projects evaluated the interactions between management and a watershed’s physical and biological processes. Information provided by completed watershed analyses is used to inform district implementation plans. 

​​Aquatic, riparian areas and wetlands are protected on state forests with a combination of site specific and landscape strategies. These strategies is to maintain or restore the key ecological functions of aquatic, riparian, and upland areas that directly influence freshwater habitat of aquatic species within the context of the natural disturbance regimes that created habitat for these species.

Site specific strategies are designed to maintain and restore aquatic-riparian functions while the landscape strategies address larger watershed scale functions. This blended approach seeks to emulate disturbance patterns in both upslope and riparian areas.​

Riparian management areas are established immediately adjacent to waterways to protect aquatic resources. Within these areas, special management considerations and operational restrictions apply. Landscape strategies are also used and include:

  • Managing thirty to fifty percent of the forest landscape for complex structure
  • Applying best-management-practices when constructing, managing, and hauling on roads
  • A risk-based approach to landslide processes​

In addition to the site-specific and landscape strategies described above, northwest and southwest Oregon state forest management plans implement a set of species of concern strategies to further maintain and enhance habitat for species of concern. The list of species and associated strategies vary throughout the state and reflects newly listed threatened, endangered, or sensitive species as designated by ODFW, the U.S. Fish and Wildlife Service, and the National Oceanic and Atmospheric Administration (NOAA).

State Lists: 

State forests provide habitat for hundreds of species of fish and wildlife in addition to meeting our scenic and economic benefits. 

On Oregon state forests, a 'take-avoidance' policy is in place to meet the requirements of the federal Endangered Species Act to reduce the potential for harming threatened or endangered species.    

The streams, rivers and lakes provide habitats for a variety of fish species. The federal government has listed some populations of coho salmon, Chinook salmon, chum salmon, steelhead trout and the Oregon chub as threatened or endangered species. 

Listing status for fish and wildlife can be found here on the ODF&W website​
