Climate and Land Use science is essential to improve understanding of past and present change; develop relevant forecasts; and identify those lands, resources, and communities most vulnerable to Earth system change processes.Our Science Strategy
Sediment deposition serves an important role in the long-term maintenance of coastal marshes. USGS investigates the mechanisms of coastal marsh elevation regulation to help predict marsh sediment requirements under various sea level rise scenarios. ...
Marine reserves and protected areas in the U.S. Virgin Islands and Puerto Rico encompass a variety of tropical ecosystems, including coral reefs, mangroves, and seagrass beds, but questions remain regarding how effective these areas are at preserving and protecting the habitats and species they encompass. USGS and collaborators address this question by examining the biodiversity and food web...
Dongting Lake, one of the wetlands that make up the floodplains of China's Yangtze River, is important habitat for migratory waterfowl and other wildlife. However, the re-engineering of the water way and the intensification of agricultural practices has contributed to changes in hydrology and sedimentation. USGS and partners from China are assessing the potential impact of these...
The Striped Newt is a small salamander found in xeric habitats (e.g., scrub, sandhill, dry flatwoods) of the lower coastal plain and northern peninsular Florida. Though once considered "common," they are currently a candidate species for federal listing. ...
The State of Florida, along with much of the southeast United States, lies along latitudes of deserts.

Advancing the international exchange of Earth data
American pikas – small herbivores that typically live in rocky slopes, known as talus, across many mountain ranges in the American West – are disappearing from some locations across the West due to climate change, according to a study by the U.S. Geological Survey and some of its partners.
Sentinel 2A's coverage shows it can be a great complement to Landsat imagery.

“From the mountains to the coast, the southeastern U.S. contains ecosystems that harbor incredible biodiversity. Many of those ecosystems are already highly at risk from urbanization and other human land-use change. Identifying the ecosystems at risk from climate change will help inform conservation and management to ensure we don’t lose that biodiversity.” (Jennifer Constanza, report author)
Natural and cultural areas that will remain similar to what they are today -- despite climate change -- need to be identified, managed and conserved as “refugia” for at-risk species, according to a study published today in PLOS One. The study sets out, for the first time, specific steps to help identify and manage these more resilient and climate-stable havens for plants, animals and fishes.
U.S. Geological Survey scientists will present their research at the Ecological Society of America meeting from Aug. 7-12, 2016, in Fort Lauderdale, Florida. The theme is "Novel Ecosystems in the Anthropocene."
