Integrated monitoring of ecological conditions in wetland-upland landscapes

Résumé fourni par la source

Landscapes of interwoven wetlands and uplands offer a rich set of ecosystem goods and services, including fresh water, food, fiber, fuel, habitat for biodiversity, genetic reserves, groundwater recharge, pollution control, flood control, sediment retention, biogeochemical cycling, recreation, aesthetics, and climate regulation.Climate and land use can alter the processes that produce these goods and services and reduce the benefits people derive from them.Managing lands to maximize ecosystem services requires information that distinguishes change caused by local actions from broaderscale shifts in climate, land use, and other forms of global change.Satellite and airborne sensors collect valuable data for this purpose, especially when the data are analyzed along with data collected from ground-based sensors.The U.S. Geological Survey is using remote sensing technology in this way as part of the Terrestrial Wetland Global Change Research Network (TWGCRN; http://www.umesc.usgs.gov/ twgcrn.html).This network of partners and research sites was created to assess effects of climate change interacting with land-use change and other potential stressors along
