Habitat Conservation & Restoration Team (HCRT) of the Gulf of Mexico Alliance (GOMA) Governor’s Action Plan II Action Item: H-3, Technology Development
Sea-level rise Affecting Marsh Model (SLAMM) Runs and Conservation Planning Data Platform Development
The HCRT partnered with The Nature Conservancy (TNC) in 2008 to assess potential impacts to coastal habitat as a result of sea level rise (SLR). TNC’s expertise and work with ecosystem assessment made them a logical choice to lead the project.
The Sea Level Affecting Marshes Model (SLAMM) model, the most widely used model for this purpose, was applied for all sites. Since all models are limited by the availability of sufficient data, the HCRT set minimum data criteria to guide site selection and to improve results.
Key stakeholders were consulted throughout the modeling process to ensure local knowledge was incorporated. The report for Galveston Bay, Texas supplied baseline data for an ecosystem services project which assessed the benefits to humans that marshes provide along with snapshots of how those could change under potential SLR scenarios. Maps can be viewed online at SLAMM View. An offline Data Platform with all the data can be requested from email@example.com. Click here to view a webinar on the project tools and products. The project yielded three kinds of reports:
Conservation Analysis: Potential impacts to ecological and human communities
SLAMM Analysis: Technical report on SLR modeling and results
Storm Surge Analysis: Technical report on storm surge modeling and results
