Estimating road age and traffic volume for disturbance assessments in Wyoming
In 2021, the Fort Collins Science Center initiated a research effort to estimate road age and annual traffic volumes across the majority of roads in Wyoming for assessing impacts to wildlife. Data on roads often focus on the ‘where’ (for example, spatial features) but neglect the ‘when’ (for example, road age) or ‘how much’ (for example, traffic volume). Knowing these characteristics is critical...
Prioritizing restoration and conservation of sagebrush ecosystems in northwestern Colorado
We are working with Colorado Parks and Wildlife (CPW) to pilot an expansion of the Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET; Duchardt et al. 2021) across northwestern Colorado. We are in the initial phase of a two-phase project where we are leveraging existing data resources to provide customized scenarios that directly guide landscape-scale conservation delivery by CPW. This...
Assessing the Proliferation, Connectivity, and Consequences of Invasive Fine Fuels on the Sagebrush Biome
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)...
New Tools for Modern Land Management Decisions
In an era of rapid land use changes and shifting climates, it is imperative that land managers and policymakers have actionable and current information available for decision processes. In this work, we seek to meet these needs through new data products and decision support tools built on digital soil mapping, new vegetation cover maps, agency inventory and monitoring data sets, and cutting-edge...
Synthesis and Forecasts of Piñon-Juniper Woodland Die-off
Drought, hotter temperatures, and insect outbreaks are affecting dryland ecosystems across the globe. Pinon-juniper (PJ) woodlands are a widespread vegetation type common to drylands of North America, which have been hit particularly hard by a warming climate. Specifically, mass tree die-off events are transforming PJ woodland structure, composition, and distributions. This project aims to...
Prioritizing sagebrush protection and restoration within the upper Colorado River Basin
Arid shrublands of western North America face growing threats from disturbances such as wildfire, drought, and invasive species. These threats are increasingly altering the sagebrush ( Artemisia species) biome and degrading habitat for species of conservation concern such as greater sage-grouse ( Centrocercus urophasianus ). Effective management and restoration are needed to slow or reverse these...
Prioritizing conifer removal for multi-species outcomes
Wildlife management is frequently conducted to benefit a single species, despite evidence that suggests such an approach often fails to adequately address the needs of other species within a region. Managing for multiple species’ habitat requirements is even more critical when large scale habitat management efforts change vegetation conditions at the landscape scale, or when management occurs at...
Predicting risk of annual grass invasion following fire in sagebrush steppe and rangeland ecosystems
This project analyzes on-the-ground plant monitoring data across sagebrush and rangeland ecosystems to examine how fire, climate, topography, and plant communities influence the success of invasive annual grasses after fires.
Soil-climate for Managing Sagebrush Ecosystems
Soil-climate describes the temperature and moisture conditions important for plant growth and function. Soil condition patterns determine which vegetation is most abundant, thus controlling which habitats, invasive species, fuels, and economic activities are present in a region. Here, we use a model to simulate the vertical movement of water in a soil profile to provide insights into landscape...
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...
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...
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...
