Understanding Avian Habitat Availability and Use After Barrier Island Restoration in Coastal Louisiana

Using ecological and geographical data, WARC researchers and their partners are analyzing avian and benthic sampling on Whiskey Island and Caminda Headland to compare pre- and post-restoration aspects of habitat occupancy, habitat availability, habitat use, and kernal density estimation.

Impacts of coastal and watershed changes on upper estuaries: causes and implications of wetland ecosystem transitions along the US Atlantic and Gulf Coasts

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...

Geospatially Enabled, Web-based Habitat Reporting Tool to Support Monitoring and Assessment along the Louisiana Shore

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.
