Coastal Ecosystems

WARC Researchers are comparing tree and root growth, soil CO2 flux, and surface elevation change between fertilized and unfertilized mangrove forests to assess the potential impact of increased nutrient loading and to help rate mangrove stand vulnerability.

WARC's wetland carbon cycle science team is working to improve model parameterizations and formulations and reduce forecast uncertainty in ecosystem modeling.

The USGS and partners are studying how mangrove forests in the Federated States of Micronesia may respond to sea-level rise over the coming century. Their projections will help Micronesian communities plan for the future.

Using an iterative qualitative coding process, WARC researchers are identifying objectives, stressors, and management priorities to support the implementation of adaptive management in restoration programs across the Gulf of Mexico.

USGS is collaborating with Mississippi State University to investigate the effects of fire on Gulf of Mexico marshes. The project will include mapping high marsh and monitoring black rail, yellow rail, and mottled duck responses to prescribed fire application.

WARC researchers will estimate the density and distribution of bobcats in relation to environmental variables through the development of spatially explicit capture-recapture and occupancy models.

The National Oceanic and Atmospheric Administration (NOAA) and USGS will jointly lead the development of foundational components for Gulf region-wide monitoring.

The State of Louisiana's Barrier Island Comprehensive Monitoring (BICM) program has partnered with USGS to developed two habitat classifications schemes for monitoring barrier island habitats and habitats in beach-dune systems along the mainland. These schemes builds upon previous BICM habitat mapping efforts.

Joint Ecosystem Modeling (JEM) provides ecological models tailored to address specific management issues, for example, the Western Everglades Restoration Project.

USGS scientists develop decision support tools to help inform management and restoration of the Greater Everglades Ecosystem.

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.

In November 2018, USGS researchers joined partners in South Florida where they sampled freshwater bodies for non-native fishes. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native fishes.
