Blackwater National Wildlife Refuge Restoration

Project Sheet

Project Type(s): Habitat restoration

Project Description: This demonstration project was conducted for ecosystem restoration purposes in an area with a history of wetland loss. A thin layer of fine grained material was sprayed in 2, 1-2 acre sites and placed hydraulically. Hydroseeding was attempted by adding seeds to the dredged material spray. The material was placed in 2 lifts of small thickness which allowed the sites to become revegetated in a short period of time. Post placement monitoring indicated revegetation occurred immediately within the refuge and outside of the treatment area as well. The total project cost was $300,000.
