Ecological Stressors

Critical information predicting condition changes in manatee habitat resulting from the alteration of freshwater flows to estuaries is needed to develop the PSRP Detailed Design and PSRP Operations Plan components and complete consultation under the Endangered Species Act.

Significant damage to coastal communities and surrounding wetlands of the north Atlantic states was caused by Hurricane Sandy in late October 2012, mostly tied to an associated storm surge of record extent and impact.

Freshwater wetlands provide critical habitat for a diverse array of organisms, including many amphibians. Yet, under the threat of climate change, these habitats are among the most imperiled ecosystems on Earth.

USGS is committed to meeting the science needs of four Native American Tribes impacted by Hurricane Sandy in New England and New York: the Wampanoag Tribe of Gay Head - Aquinnah on Martha’s Vineyard, MA; the Mashpee Wampanoag Tribe on Cape Cod, MA; the Narragansett Indian Tribe near Charlestown, RI; and the Shinnecock Indian Nation on Long Island.

This project will create a Climate Change Adaptation Plan for the Chitimacha Tribe of Louisiana (Chitimacha), serving as an implementable plan for coastal community adaptation to climate change that can be used as a model in other small communities.

Using historic maps and contemporary imagery, we will quantify and synthesize existing data on the distribution and abundance of shorebirds in North Carolina and changes in habitats related to storms, such as Hurricane Sandy; coastal development, such as the Intracoastal Waterway; inlet modifications; and shoreline erosion to give us a better understanding of historic trends for shorebirds and...

While the historic focus of vegetation condition is the bulk live and dead compositions, these variables provide no information on the structure of vegetation (density and orientation). Canopy structure information is critical for monitoring status and trends, and essential in climate, weather, and ecological studies.

Storm surge waves and tides of hurricanes have the propensity to wash up marsh detritus of dead reeds and leaf debris along with plastic trash and lumber, commonly referred to as wrack, from overwashed beaches, marshes, forests, streets, and lawns.

Support tasks performed by the WARC Advanced Applications Team for Hurricane Sandy-related projects include aerial imagery capture and processing, standards-compliant data formatting and transformation, metadata creation, and visualization of data in a spatial context.

As custodians of ecological goods and services valued by society, coastal National Wildlife Refuges (NWRs) have an especially important role to play in helping socio-ecological systems adapt to global-change processes.

The Joint Ecosystem Modeling team is developing and applying ecological models and other decision support tools for Greater Everglades restoration project planning.

Prescriptions in the forest habitat management plan for Tensas River National Wildlife Refuge are designed to produce a forest once represented in the Tensas Basin. There are several problems with reconstructing original forests. In most areas, conditions have changed since these forests were cut; particularly, hydrology, soils, and climatic conditions.
