Disturbance

Land managers require clear, forward-looking information about where and how vegetation treatments may make the greatest difference for drought resilience in sagebrush and woodland ecosystems. We are using soil moisture and vegetation data from SageSTEP-- a long-term ecological study on fuel treatments in the Great Basin-- to analyze soil moisture dynamics and vegetation responses after common...

We are investigating ecosystem transitions and thresholds in the sagebrush steppe, studying factors influencing the shift from native to invaded plant communities after disturbances like fire. Our research tests region-wide resistance and resilience models, focusing on real-world recovery patterns, pre-fire conditions, plant succession, and land management treatments.

Wildfires are increasingly destroying wildlife habitat in sagebrush ( Artemisia species) ecosystems, and managers need approaches to scope the pace and degree to which post-fire restoration actions can re-create habitat in dynamic landscapes. Sagebrush recovery takes a long time, and it can be difficult to anticipate restoration outcomes over large, diverse landscapes that have experienced decades...

Increased wildfire-induced loss of sagebrush in North American shrublands are outpacing natural recovery and leading to substantial habitat loss for sagebrush-obligate species like sage-grouse. Transplanting sagebrush ( Artemisia species) is a possible strategy for revegetating burned areas, but little is known about sage-grouse or other wildlife responses to restoration strategies.

We are studying how herbicides sprayed onto soil to prevent the establishment of exotic annual grasses such as cheatgrass may impact the health, growth resources and microbiota of soils in sagebrush-steppe, where herbicide use is an important and common tool. Our findings will help make herbicide applications more successful.

Management partners have identified a major need to understand the short and long-term consequences of altered wildfire patterns, vegetation change, climate change, and management actions for the carbon cycle. This project aims to quantify carbon storage and greenhouse gas emissions in sagebrush rangelands. Researchers will link findings to the Sagebrush Conservation Design Framework and provide...

The USGS is leading a multi-disciplinary team with members from government, academia, non-profits, and industry, to generate science to inform resolution of wildlife-related issues that can impede development and operations of wind and solar energy facilities.

Wildlife issues drive many federal and state land management decisions, either because of litigation or mandates to protect habitat and limit extinction risks. We conduct applied research to meet this need, particularly related to the effects of natural (disease, predation) and anthropogenic (habitat loss, invasive species) stressors on wildlife populations and communities. Research on the effects...

Conifer forests in the Pacific Northwest are biologically and economically important, are intensively managed for multiple uses, and represent a large area in public domain. Therefore, understanding how management of conifer forests affects biodiversity across a range of spatial and temporal scales is critical for land management agencies.
