Regional Ecosystems Research

Managing wildland fuels and post-fire environments are key strategies to reduce the risk and negative impacts of wildfire, and can even promote beneficial effects of wildfire. Researchers from the U.S. Geological Survey are reviewing, summarizing, and analyzing what is currently known about fuel treatment and post-fire treatment effectiveness in the United States. Monitoring and evaluating the...

This web-based mapping tool, released in 2024, enables users to identify which threats are driving the current status of Sagebrush Ecological Integrity (SEI), assess if SEI and associated threats, such as invasive annual grass, conifer encroachment, human modification - have changed over time, and visualize spatial trends in SEI and threats. The Sagebrush Ecosystem Trends Module supports managers...

The CED Gunnison Sage-grouse Recovery Module was released in 2020 and is designed to capture any effort designed to benefit Gunnison sage-grouse recovery. This includes habitat restoration and any activities that contribute to the recovery of Gunnison sage-grouse, a federally listed threatened species. While similar to the Sagebrush Module, The Gunnison Sage-Grouse Recovery module contains fields...

The CED Cutthroat Module, released in 2024, is our latest module and is designed to capture any action related to the conservation, enhancement, restoration, or recovery of native, inland cutthroat trout or the habitats and waters that they depend on. The first iteration of this module was designed specifically for the Lahontan cutthroat trout. However, we are currently working on expanding the...

The CED Sagebrush Module, first released in 2014, captures any conservation effort, enhancement, restoration, plan, or action related to the sagebrush landscape or activities that benefit sagebrush-dependent species. The CED was originally focused only on greater sage-grouse and thus, most of the records currently in our database are related to this species, but, starting in 2019, we expanded our...

USGS is investigating the impact of the annual grass-fire cycle-- and restoration land treatments aimed at slowing that cycle-- on carbon storage in dryland soils.

USGS is identifying, testing, and verifying rapid methods for rangeland assessment and restoration monitoring. Our methods complement existing monitoring frameworks, providing land management agencies with timely information that can be used to determine if restoration investments are successful, and why. Standardization, validation, repeatability, data management, and training are at the core of...

Using thermal cameras, we are determining the population size and cave occupancy of the Mariana swiftlet and Pacific sheath-tailed bat. Both species face extirpation from the Northern Mariana Islands and are listed as endangered. Understanding the species' population status can assist in planning recovery efforts for both species.

Climate change and invasive species are transforming ecosystems. The Resist-Accept-Direct (RAD) framework organizes management objectives into those that seek to Resist change and maintain historical ecological communities, those that Accept some or all aspects of ecological transformation, and those that Direct an ecological community to a preferred state. We are evaluating risks posed by climate...

City of Rocks National Reserve and Craters of the Moon National Monument and Preserve are lands managed by the National Park Service that contain ecologically valuable stands of sagebrush and unique forest communities that are at risk due to wildfire and invasion by exotic annual grasses. We are working to determine the extent of invasion and to provide park managers with wildfire risk assessments...

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...

The Sagebrush Steppe Treatment Evaluation Project--or SageSTEP-- is a regional experiment taking place across six states in the Great Basin. A multidisciplinary team of scientists are evaluating methods of sagebrush steppe restoration to inform land managers working to protect one of the most threatened land types in North America. SageSTEP is the longest running and largest replicated ecological...
