Assessing invasive annual grass treatment efficacy across the sagebrush biome
We are using existing datasets that span broad spatial and temporal extents to model the efficacy of invasive annual grass treatments across the sagebrush biome and the influence of environmental factors on their success. The models we develop will be used to generate maps of predicted treatment efficacy across the biome, which will be integrated into the Land Treatment Exploration Tool for land...
Creating range-wide predictive maps of Greater Sage-Grouse seasonal habitats
Through a collaborative effort with multiple state and federal agencies, university researchers, and individual stakeholders, we are producing a set of predictive seasonal habitat maps for greater sage-grouse ( Centrocercus urophasianus ) spanning the entirety of the species’ U.S. distribution. This is the largest habitat modeling effort of its kind for the species and uses a large, compiled...
Predicting Recovery of Sagebrush Ecosystems Across the Sage-grouse Range from Remotely Sensed Vegetation Data
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, climate change projections...
Understanding Population Trends for the Gunnison Sage-Grouse to Inform Adaptive Management
In partnership with the Bureau of Land Management and Colorado Parks and Wildlife, scientists from USGS Fort Collins Science Center and Western Ecological Research Center are applying a hierarchical monitoring framework to Gunnison sage-grouse ( Centrocercus minimus ) to evaluate population trends and inform adaptive management.
Wild horse and livestock influences on vegetation and wildlife in sagebrush ecosystems: Implications for refining and validating Appropriate Management Level (AML)
USGS researchers are conducting a comprehensive study of wild horse and livestock records across the greater sage-grouse range to investigate impacts on vegetation and wildlife (specifically, sage-grouse and songbirds). Researchers will use these results to evaluate Appropriate Management Levels for wild horse and burros, and projections of vegetation productivity under a changing climate.
Using simulation models to project and evaluate post-fire success in restoring sage-grouse habitat over large landscapes
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...
Simulating the influence of sagebrush restoration on post-fire sage-grouse population recovery
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.
Linking post-fire sagebrush restoration and sage-grouse habitat recovery
Many revegetation projects are intended to benefit focal wildlife species. Yet, few scope the ability of revegetation efforts to yield habitat. To investigate the ability of alternative sagebrush ( Artemisia species) planting strategies to recover habitat conditions for the greater sage-grouse ( Centrocercus urophasianus ), USGS and Colorado State University scientists developed a spatial...
Economic assessment of addressing annual invasive grasses across the sagebrush biome
This interdisciplinary project combines expert judgment on treatment costs with spatially explicit ecological modeling to estimate the financial resources needed to address the threat of invasive annual grass across the entire sagebrush biome. Results of the assessment will provide economic insights that can inform cost-effective resource allocation to efficiently achieve sagebrush conservation...
Modeling Songbird Density-Habitat Relationships to Predict Population Responses to Environmental Change Within Pinyon-juniper and Sagebrush Ecosystems
Within areas of overlapping sagebrush and pinyon-juniper ecosystems, wildlife populations are declining due to habitat fragmentation and degradation, changing climate, and human development. However, management to bolster species associated with one ecosystem may result in negative consequences for species associated with the other. Thus, land managers are challenged with balancing which system to...
Developing habitat models for rare plants to inform decision making on multiple-use public lands
Public lands provide important habitat for many rare plants. However, public lands often need to accommodate many other uses, including traditional and renewable energy development, in addition to conservation. We are working with the Bureau of Land Management to coproduce ensemble habitat suitability models that can inform agency planning and permitting decisions that may impact rare plants.
Long-term, Place-based, Science and Ecological Monitoring
For over 30 years we have monitored the ecosystem dynamics of the mesas and mountains of northern New Mexico, co-located with mangers. We use a place-based science approach, defined as “science that is founded on long-term, repeated, field data and observations, as well as traditional knowledges, and regularly engages local managers and community members.” This approach enables us to provide land...
