YEAR 2003 - CRP Project #2007 (Gulf of Mexico)

Project #2007
Restoration of Fish Habitat

Gulf Islands National Seashore, Mississippi

Project staff and volunteer monitor seagrass being grown in the Gulf
Coast Research Laboratory. The seagrass will be used to restore
shallow areas in the water around Horn Island.

Grantee: Gulf Coast Research Laboratory
Project location: Horn Island, Mississippi
Grant period: March 1, 2021 - Sept 30, 2021 (extended to Dec 31, 2020)
Grant amount: $75,000
Land Ownership: US National Park Service
Lat/Long: N 30.25, W 88.8

Species Benefitting From Restoration:
  • marine fish
  • shrimp, crabs and other invertebrate species
Project Goals:
  • Plant sea grass Thalassia thestudinum (turtle grass)
  • Determine shoot density, light and current velocity requirements of sea beds (through monitoring)
  • Increase community awareness of importance of sea grass to fish habitat
  • Determine potential success of sea grass restoration
  • Benefit marine species by providing habitat
  • Reduce erosion to barrier island

Project History:

Low salinity levels caused by release of a spillway into the Mississippi River, plus excess rainfall, reduced sea grass species from six to two. Thalassia thestudinum (turtle grass) no longer present in area since early 1970s. Nearest source where light and salinity are similar is Big Lagoon, Florida (60 miles away). This species grows up to 3 feet long and exhibits thick leaves. Thalassia forms extensive beds that effectively reduce wave action and serve as excellent habitat for fish and finfish.

Thalassia thestudinum has been planted at the Horn Island project site. The plant was present until the 1970s when low salinity levels killed it out.
