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.

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.

Halodule (shoal grass) along the north side. Thalassia, although
historically present, has not occurred here since the early 1970s.
