Riparian Vegetation Response to Dam Removal
Dam removal is an approach to river restoration that is becoming increasingly common. In most cases, dam removal is driven by considerations other than river restoration like dam safety, but how dam removal affects aquatic and riparian systems is of great interest in many dam removals. Scientists work in this area has had two areas of focus thus far: 1) studies of vegetation and geomorphic change...
Energy Development and Changing Land Uses
Applied research and integrated regional assessments emphasize spatially explicit analyses of ecosystem components affected by energy development and land-use change in the western United States. Topics include sagebrush-steppe ecology; sagebrush habitat assessments; the effects of human activities (including energy development, transportation, and recreation) on habitats and wildlife behavior...
Wyoming Landscape Conservation Initiative: Inventory and Long-Term Monitoring
The Wyoming Landscape Conservation Initiative (WLCI) addresses effects of land-use and habitat changes on Southwest Wyoming’s natural resources. In partnership with twelve Federal, State, and local natural resource agencies, and non-governmental organizations– FORT and ten other USGS centers are conducting dozens of integrated science projects to assess the status of Southwest Wyoming’s natural...
Wyoming Landscape Conservation Initiative: Mechanistic Studies of Wildlife
The Wyoming Landscape Conservation Initiative (WLCI) addresses effects of land-use and habitat changes on Southwest Wyoming’s natural resources. In partnership with twelve Federal, State, and local natural resource agencies, and non-governmental organizations– FORT and ten other USGS centers are conducting dozens of integrated science projects to assess the status of Southwest Wyoming’s natural...
Wyoming Landscape Conservation Initiative: Baseline Synthesis
The Wyoming Landscape Conservation Initiative (WLCI) addresses effects of land-use and habitat changes on Southwest Wyoming’s natural resources. In partnership with twelve Federal, State, and local natural resource agencies, and non-governmental organizations– FORT and ten other USGS centers are conducting dozens of integrated science projects to assess the status of Southwest Wyoming’s natural...
Wyoming Landscape Conservation Initiative: Effectiveness Monitoring
The Wyoming Landscape Conservation Initiative (WLCI) addresses effects of land-use and habitat changes on Southwest Wyoming’s natural resources. In partnership with twelve Federal, State, and local natural resource agencies, and non-governmental organizations– FORT and ten other USGS centers are conducting dozens of integrated science projects to assess the status of Southwest Wyoming’s natural...
Landscape and Habitat Assessment
A central focus of this program is to conduct multi-scale assessments in order to develop related geospatial decision-support tools and methods. The program includes synthesizing broad-scale datasets and developing innovative approaches to assess the vulnerability and resilience of wildlife habitats and ecosystems, relative to land management decisions and ecosystem stressors on Department of the...
The Western Mountain Initiative (WMI)
Western Mountain Initiative (WMI) is a long-term collaboration between FORT, WERC, NOROCK, USFS, NPS, LANL, and universities worldwide to address changes in montane forests and watersheds due to climate change. Current emphases include altered forest disturbance regimes (fire, die-off, insect outbreaks) and hydrology; interactions between plants, water, snow, nutrient cycles, and climate; and...
Tree Mortality Patterns and Processes
Episodic droughts have long been known to trigger accelerated tree mortality in forests worldwide, including in the Southwest U.S. Scientific understanding of the process drivers and spatial patterns of tree mortality is surprisingly limited, constraining our ability to model forest responses to projected increases in drought. The onset of regional drought since the late 1990s has resulted in...
Post-fire Recovery Patterns in Southwestern Forests
High-severity crown fires in Southwestern dry-conifer forests — resulting from fire suppression, fuel buildups, and drought — are creating large treeless areas that are historically unprecedented in size. These recent stand-replacing fires have reset extensive portions of Southwest forest landscapes, fostering post-fire successional vegetation that can alter ecological recovery trajectories away...

Ecological Flows
This research examines how water flows affect populations, communities, ecosystems, and hydroscapes. Studies elucidate the interactions among hydrologic, geomorphologic, biogeochemical, biological, and anthropogenic processes. Scientists identify and quantify the spatial and temporal attributes of water flow for ecological needs. Flow alternations by humans are a primary contributor to the...
