A Vegetative Model for Restoration, Conservation, and Habitat Enhancement on Beneficial-Use Dredge Sediments, GMP project #MX974606

Being Conducted for the Bartaria/Terrebonne National Estuary Program by Mike Materne, LSU Ag Center

About this Project

The goal of this project is to develop baseline information on environmental parameters affecting the selection, establishment, and growth of plant species for dredge-restored sites. The specific objectives of the study are 1) to implement a comprehensive program of dredge materials/plant species research; 2) to initiate steps which reduce the time required for the establishment of productive plant communities on dredge materials; 3) to develop a methodology to re-vegetate and manage dredge materials that will support a more increased plant species-rich habitat than is currently being realized; 4) to identify the physical, chemical, and biological factors which control the success or failure of dredge material vegetative plantings; and 5) to provide planners, designers and builders with management strategies that incorporate an ecological and environmental perspective into dredge-material engineering.
