GIS Support and Spatial Analysis Support for the Louisiana Division of Administration, State Land Office

The Wetland and Aquatic Research Center (WARC) first implemented geographic information systems (GIS) in 1980 to assist in monitoring the nature and extent of wetland habitat changes. The geospatial capabilities at the Coastal Restoration Assessment Branch (CRAB), in part, grew out of that initial effort and now use GIS, remote sensing, and other computer based technologies to address a wide...

Mangrove Migration Network

At the poleward marsh-mangrove ecotone, mangrove abundance and coverage is winter temperature-sensitive in that it oscillates in response to the frequency, duration, and/or intensity of extreme winter temperatures. Future winter climate change is expected to facilitate poleward mangrove range expansion at the expense of salt marshes in Texas, Louisiana, and parts of Florida.
