Large, stand-replacing wildfires are expected to become increasingly common due to climate change, but there are limited scientific data available to help managers evaluate options for forest manag

As wildfires increase in size and frequency throughout the western United States, and interest in carbon accounting grows, accurate and efficient methods for measuring carbon flux are critical.

Sport hunting of deer, elk, and other wild ungulates is a popular recreational activity on federal lands.
Willows planted to improve riparian habitat for fish also provide an important early-season foraging resource for native bees. Photo courtesy of Scott Mitchell.
Native pollinators are critical to healthy ecosystems, including rangelands, but pollinators are in decline.
Stage 0 restoration on the South Fork McKenzie River, Oregon, used earth-moving machinery to fill incised channels and place thousands of logs to ultimately benefit fish and restore floodplains. USDA Forest Service photo by Steve Wondzell.
Stage 0 restoration is a new approach that essentially resets a flood plain.

Fruit- and nut-producing shrubs such as huckleberries (Vaccinium sp.) and California hazel (Corylus cornuta) are key components of many ecosystems in the Pacific Northwest.
