WARC researchers sampled anuran populations at sites within Big Thicket National Preserve to explore saltwater intrusion on these populations.

Estuaries and their surrounding wetlands are coastal transition zones where freshwater rivers meet tidal seawater. As sea levels rise, tidal forces move saltier water farther upstream, extending into freshwater wetland areas. Human changes to the surrounding landscape may amplify the effects of this tidal extension, impacting the resiliency and function of the upper estuarine wetlands. One visible...

South Florida's pine rockland ecosystem represents less than 3% of its original extent. This project will evaluate habitat conditions for two pine rockland snake species to develop future habitat condition scenarios for Species Status Assessments.

A USGS forecasting tool helps Everglades natural resource managers identify management actions that can benefit one or more species while quantifying the potential costs to others.

The Louisiana Coastal Protection and Restoration Authority’s Coastal Master Plan is a blueprint for responding to environmental changes. As part of the agency’s continued engagement, USGS supports model developments and improvements for the 2023 Coastal Master Plan.

National Wildlife Refuges provide habitat for important fish and wildlife species and services that benefit coastal communities, like storm-surge protection. USGS scientists are helping coastal refuges plan for and adapt to sea-level rise.

Relict forests (i.e., forests unable to reestablish after disturbance) may develop in the southeastern U.S. in future predicted extreme climates of temperature, flooding, and drought, according to the International Panel on Climate Change.

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.

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.

In Central America, “tropical dry wetlands” provide numerous ecosystem goods and services. The mosaic of wetlands within and around Palo Verde National Park (a Ramsar Wetland of International Importance) is one of the largest complexes in the region.

Barrier island resource managers within the northern Gulf of Mexico have the opportunity to more directly incorporate scientific uncertainties and technological challenges inherent with large-scale barrier island restoration projects, and as such, commit to developing robust long-term monitoring programs and applying adaptive management.

The science of dating growth rings and history of live and fossil wood samples is called dendrochronology. This technique is valuable for conducting climate reconstructions where meteorological data is lacking and for detecting past disturbance events such as tropical storms and hurricanes.
