The Lake Tahoe basin is a prime example of a landscape in which high-value ecological and social outcomes hang in the balance as climate changes over the next century.

Hot, dry air conditions fuel more intense wildfires, while cool, moist air conditions can make fires easier to manage.

Armillaria root diseases are a major cause of mortality and reduced growth of trees in forests worldwide. Trees stressed by drought, high temperatures, and other environmental stressors may be predisposed to Armillaria infection.

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 management after wildfire.

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. This study provides an applied example of a quasi-experimental approach to quantify the effects of a natural disturbance for which experimental settings are unavailable.

As the frequency and size of wildfires increase, accurate assessment of burn severity is essential to understanding fire effects and evaluating those effects on postfire vegetation. Remotely sensed imagery allows for rapid assessment of burn severity, but it needs to be field validated.

A newly revised toolbox in ArcGIS enables users to project nutrition and habitat use for elk across 11 million hectares of western Oregon and Washington. Wildlife biologists and forest planners can also use the toolbox to evaluate how management alternatives will likely affect elk habitat.

Sport hunting of deer, elk, and other wild ungulates is a popular recreational activity on federal lands.

Native pollinators are critical to healthy ecosystems, including rangelands, but pollinators are in decline.

Pollinators—any species that moves pollen on a plant and supports plant fertilization—are essential to ecosystems worldwide. Despite their critical importance, pollinators are largely undervalued and understudied.
