Project Title: Sea-level rise Affecting Marsh Model (SLAMM) Analyses for GOM National Wildlife Refuges

Individual reports on sea level rise model results have been produced for each of five study areas:

• Great White Heron NWR, Florida
• Ten Thousand Islands NWR, Florida
• Lower Suwannee NWR, Florida
• Mississippi Sandhill Crane NWR, Mississippi
• San Bernard & Big Boggy NWRs, Texas

These sites were selected from a list of 21 refuges that the U.S. Fish & Wildlife Service had proposed modeling for but that had not been funded.

Proposed sites for which available data did not meet HCRT minimum data requirements (see pdf link below) were trimmed from that list. In the HCRT’s first foray into sea level rise modeling, data requirements were developed in the interest of improving the reliability of results and thereby make the best use of project funding. The final reports contain a lot of technical information but also graphical depictions of the changes projected under the various scenarios and up through 2100.
