Restoration Activities
Case: Dixon Bay, LA
Project Description
A crevasse was constructed through the Mississippi River levee in the
"Birdfoot" Delta to create 21 acres of emergent estuarine wetlands. This
restoration effort will replace marsh that was injured by oiling, provide
wildlife and estuarine nursery habitat, and promote storm and erosion
protection.
Project Details
In February 1996, Chevron dredged a crevasse in a levee to create a freshwater
diversion into the Delta National Wildlife Refuge, which is managed by the U.S.
Fish and Wildlife Service (FWS). Dominant plant species are Scirpus spp.
and Sagittaria spp., and monitoring is in progress. Freshwater
diversion projects have become instrumental in countering the high rate of
subsidence and land loss in the delta by providing sediments needed for land
accretion and marsh creation.
