Ecosystem Restoration

Encompassing over 175 million acres, America’s “Sagebrush Sea” is the largest terrestrial ecosystem in the lower 48 states. A predominately shrubland system, this landscape ranges over deserts, valleys, mountains, and mesas from the Canadian border to our southwestern deserts. The sagebrush ecosystem – the ancestral homeland of many Tribal Nations – supports critical agricultural and recreation...

Invasive annual grasses are spreading across the sagebrush ecosystem, threatening the survival of native plant species and the wildlife habitats they support. Researchers from the U.S. Geological Survey, Colorado State University, University of Wyoming, the Bureau of Land Management, National Park Service, and the U.S. Fish and Wildlife Service are collaboratively investigating the factors that...

Invasive annual grasses can replace native vegetation and alter fire behavior, impacting a range of habitats and species. A team of researchers from the U.S. Geological Survey, Colorado State University, the Bureau of Land Management, and the U.S. Fish and Wildlife Service are working to identify factors that influence changes in the distribution and abundance of invasive annual grasses (IAGs)...

Bureaus within the Department of the Interior are working together to build a framework to assess restoration outcomes. USGS is leading this effort that will inform landscape-level resource management and increase benefits from restoration investments.

The Conservation Efforts Database (CED) is a secure online data repository that collects, stores, and retrieves spatially explicit, spatially obscure, and non-spatial information on species and habitat conservation and management actions. The CED is designed to allow data collection from all interested partners including federal, state, local, non-government organizations, universities, private...

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 researchers are using remote-sensing and other broadscale datasets to study and predict recovery of sagebrush across the sage-grouse range, assessing influence of disturbance, restoration treatments, soil moisture, and other ecological conditions on trends in sagebrush cover. The results will be used to inform conservation prioritization models, economic analyses, projections of future...

Land managers face tremendous challenges in the future as drought and climate change alter the abundance, distribution, and interactions of plant species. These challenges will be especially daunting in the southwestern US, which is already experiencing elevated temperatures and prolonged droughts, resulting in reduced soil moisture in an already water-limited environment.
