USGS researchers assessed how climate change can affect land cover and flow in river systems, examining a variety of resolutions for detecting and projecting the conditions of aquatic habitats and species.

The Southeastern United States spans a broad range of physiographic settings and maintains exceptionally high levels of faunal diversity. Unfortunately, many of these ecosystems are increasingly under threat due to rapid human development, and management agencies are increasingly aware of the potential effects that climate change will have on these ecosystems. Natural resource managers...

To develop effective adaptive management plans, conservation and natural resource managers need to know how climate change will affect the species and ecosystems they manage. This project provides managers with information about potential climate change effects on species and managed areas in the Pacific Northwest. We evaluated projected changes in climate, vegetation, and species...

Climate change has emerged as a key environmental concern of the 21st century and a major challenge for land and wildlife managers. Although scientists have made tremendous progress in predicting the impact of climate change on a regional and global scale, drilling down such projections to a locally applicable form has been difficult. A major project of the US Geological Survey's (USGS)...

This project built on an existing regional conservation partnership to use the most recent downscaled climate model projections to forecast the likely impacts of climate change to species and ecosystems in the Lower Mississippi Valley (LMV). The objective of this work was to develop and test ecological and biological models to facilitate regional adaptive management of wildlife resources...

Florida is home to 50 endangered species, 23 National Wildlife Refuges, 9 national parks, and 119 state parks. Straddling both temperate and sub-tropical zones, the state is also unique in that it is a long and narrow peninsula, surrounded on three sides by warm water, creating a dynamic environment. The impacts of climate change, such as sea-level rise and severe storms, threaten the...

If current climate change trends continue, rising sea levels could inundate low-lying islands across the globe. The Northwestern Hawaiian Islands (NWHI) is a group of islands of great conservation importance that is threatened by sea-level rise. Stretching 2,000 km beyond the main Hawaiian Islands, the NWHI are a World Heritage Site and part of the Papahānaumokuākea Marine National...

The San Francisco Bay estuary contains the largest remaining expanse of tidal salt marshes in the western U.S. These marshes are home to a variety of federal and state protected species, such as the California clapper rail, California black rail, and the salt marsh harvest mouse. The estuary is also located on the Pacific Flyway, and is an important site for migrating and wintering birds...
