Western Ecological Research Center (WERC)
The Western Ecological Research Center (WERC) is a USGS Ecosystems Mission Area operation serving primarily California and Nevada. WERC scientists work closely with Federal, State, academic, and other collaborators to address a diverse array of high-profile topics. Topics include research on effects of wildfire, sea level rise, drought, energy development and more on federal Trust species.

Effects of harmful algal blooms on amphibians and reptiles are under-reported and under-represented
Harmful algal blooms (HABs) are a persistent and increasing problem globally, yet we still have limited knowledge about how they affect wildlife. Although semi-aquatic and aquatic amphibians and reptiles have experienced large declines and occupy environments where HABs are increasingly problematic, their vulnerability to HABs remains unclear. To inform monitoring, management, and future research,
Rangewide occupancy of a flagship species, the Coastal California Gnatcatcher (Polioptila californica californica) in southern California: Habitat associations and recovery from wildfire
The Coastal California Gnatcatcher (Polioptila californica californica), a federally threatened species, is a flagship species for regional conservation planning in southern California (USA). An inhabitant of coastal sage scrub vegetation, the gnatcatcher has declined in response to habitat loss and fragmentation, exacerbated by catastrophic wildfires. We documented the status of gnatcatchers thro
Geographic principles applied to population dynamics: A spatially interpolated integrated population model
A major impediment to wildlife conservation and management, from a quantitative perspective, is dealing with high degrees of uncertainty associated with population estimates. Integrated population models (IPMs) can help alleviate that challenge, but they are often limited to narrow spatial or temporal windows owing to the financial and logistical burdens of acquiring requisite datasets. To expand

Estimating Methylmercury Injury to Birds—“The Bird Mercury Tool”
U.S. Geological Survey (USGS) scientists have developed a tool that can be used by practitioners to help interpret injury to birds caused by methylmercury contamination. This tool was developed from a comprehensive review of 168 studies and summarizing data on the effects of methylmercury on birds.
Developing a Decision Support Tool to Assess Carbon Sequestration on Natural Resource Conservation Service’s Wetland Reserve Easements in Kentucky and Tennessee
USGS is developing a decision support tool to help managers quantify the impact of wetland restoration on carbon sequestration in wetland reserve easements in Kentucky and Tennessee.
Characterizing Post-Fire Burn Severity And Vegetation Recovery At High Spatial And Temporal Resolutions Using Basal Area Measurements
USGS scientists are studying the effects of wildfires on forests and developing models to predict forest recovery potential after fires. They have collected and analyzed data from several recent California wildfires, including the Dixie, Caldor, KNP Complex, Carr, and Mosquito fires. Researchers are using the data to analyze changes in basal area (the cross-sectional area of tree trunks) to...
