This number has remained unchanged since 1953. Figure 2. A recently harvested and replanted forest stand near Oakland, OR (Christine Buhl, ODF). For over a decade, Oregon has been the #1 timber producer in the U.S., accounting for 18% of the nation’s total softwood production at about 5.2 billion board feet annually. Oregon supplies 30% of the nation’s plywood with 2.5 billion board feet annually and hosts 25% of the engineered wood (glulam, I-joist, laminated veneer, cross-laminated timber) facilities in the U.S. In 2019, forest timber products brought in over $10 billion in revenue and supplied about 3% of total statewide employment. Additionally, 25% of U.S. Forest Service (USFS) and 50% of Bureau of Land Management (BLM) timber revenues help fund education, road construction, libraries, fire and police protection across the state. Oregon’s forests cover approximately 30 million acres and consist of federal (60%), private (35%), state (3%), tribal (1%), and other public (1%) ownerships. Timber production is not the primary objective across the state. The Forest Practices Act (OAR 629) guides private landowners on how best to manage their forestlands to promote ecosystem functioning and sustainability while utilizing this renewable resource. There are certification processes (Sustainability Forestry Initiative, American Tree Farm System, Forest Stewardship Council) in place to help consumers identify products grown and harvested under specific standards.

Proportion of acres owned (outer ring) and acres harvested in 2019 (inner ring) by landowner type. 2 FOREST HEALTH SUMMARY Insects, diseases and abiotic disturbance agents cause significant tree mortality, growth loss, and damage in Oregon forests each year. Large outbreaks and invasive exotic species can affect the function and resilience of forest ecosystems and may contribute to hazardous forest fire conditions. However, these agents also play a critical role in maintaining healthy, functioning forests by contributing to decomposition, nutrient

  • Habitat Description--White Fir (WFR)
    California Wildlife Habitat Relationships System California Department of Fish and Game California Interagency Wildlife Task Group White Fir Karen Shimamoto Vegetation Structure-- The White Fir (WFR) habitat is characterized by nearly monotypic even- aged overstory (Cheatham and Haller 1975, Paysen et al, 1980, Riegel 1982, Rundel et al. 1977). Overlapping crowns that cast deep shade are characteristic, although open stands are common (Cheatham and Haller 1975, Eyre 1980, Riegel 1982). Northern California specimens grow to about 70 m (230 ft) in height. Southern California specimens grow to about 30 m (100 ft) (Cheatham and Haller 1975). The understory may consist of sparsely scattered grasses, forbs, and shrubs, or white fir seedlings and saplings (Cheatham and Haller 1975, Eyre 1980, Paysen et al. 1980). However, on moist swales or drainage bottoms, herbaceous cover may approach 100 percent (Rundel et al. 1977). Downed material usually consists of logs, branches and needle litter (Cheatham and Haller 1975). Fire influences the white fir habitat by causing a mosaic of even-aged stands in different successional stages. Composition-- Mature white fir stands, normally monotypic, with more than 80 percent occurring as white fir, are found throughout California; from the Klamath Mountains along the north coast to the south coast mountain ranges, and in interior ranges from the Warner Mountains in the Great Basin to the Clark, Kingston, and New York mountain ranges in interior southern California (Rundel et al. 1977, Parker and Matyas 1981). Shade and downed woody material tend to inhibit understory species (Parker and Matyas 1981). In the Klamath Mountains, for example, canyon live oak and chinquapin are the predominant understory species and open stands usually include squawcarpet and barberry.

  • Modoc National Wildlife Refuge
    U.S. Fish & Wildlife Service Modoc National Wildlife Refuge Final Comprehensive Conservation Plan and Environmental Assessment December 2009 Vision Statement “Located near the confluence of the north and south forks of the Pit River, Modoc National Wildlife Refuge will conserve, restore, protect, and manage a mosaic of seasonal wetlands, semi- permanent wetlands, wet meadows, riparian, and sagebrush-steppe habitats. These habitats will provide important resting, feeding, and nesting areas for ducks, geese, and other migratory birds. Modoc Refuge’s high- quality habitat will play a key role in the long-term recovery of Central Valley greater sandhill cranes. As an integral part of the surrounding community, Modoc Refuge will provide high quality wildlife-dependent recreation including hunting, fishing, wildlife observation, photography, and interpretation. The Refuge will continue to be known for its high-quality environmental education program offered to generations of students. Visitors will develop a greater understanding and appreciation for the mission of the National Wildlife Refuge System and refuge management programs and for the importance of protecting lands for wildlife conservation.” Disclaimer CCPs provide long term guidance for management decisions and set forth goals, objectives, and strategies needed to accomplish refuge purposes and identify the Service’s best estimate of future needs. These plans detail program planning levels that are sometimes substantially above current budget allocations and, as such, are primarily for Service strategic planning and program prioritization purposes. The plans do not constitute a commitment for staffing increases, operational and maintenance increases, or funding for future land acquisition.

In the valley, coveys of quail trickle across the quiet streets in little towns. At twilight, herds of mule deer join cattle and sheep in the green fields. There are no stoplights, no traffic, and no sirens. This is where the paved road ends. This place, Surprise Valley, is so removed, so distinct from the rest of California, that you, like others, may come to find that it is the Golden State’s best kept secret.

Elk, or Wapiti, meaning “ghost kings” as named by the Shawnee Indians due to the animals’ elusive behavior are coming back from a precipitous population decline. The Department of Fish and Wildlife is proud to present this adaptive, scientifically based management plan that considers the many challenges facing elk in the most populous state in the nation. We’ve come a long way.
