USGS research into environmental stressors (e.g., climate, drought, floods, wildland fire) and anthropogenic stressors (e.g., energy production, urban encroachment, water abatement) provides managers with information to reduce or eliminate impacts from stressors to fish and wildlife populations and advances our understanding of the efficacy of conservation and adaptation actions to mitigate land-use and climate change impacts on sensitive species.
