Marsh Restoration

Salt marsh - USFWS.

Restoration to back-barrier salt marsh habitats from currently degraded open water conditions will rely on re-building dunes, restoring edaphic factors, hydrological and salinity regimes needed to support the natural recolonization of smooth saltmarsh grasses in Unit II and parts of Unit III.

  • Prescribed Burning - A Success!

    Prescribed Burning Promo2

    Prime Hook National Wildlife Refuge, in partnership with the U.S. Fish and Wildlife Service’s Zone Fire Staff from the Blackwater National Wildlife Refuge in Cambridge, Maryland, local fire departments, and the Delaware Forest Service, successfully burned 90 acres of successional field habitat on April 11, 2014. Prescribed burning sets back succession to early stages to benefit grassland dwelling birds, counteracts against undesired plant species and removes accumulated wildland hazardous fuels as planned in the refuge’s Comprehensive Conservation Plan. The use of prescribed fire is an effective and cost efficient method to accomplish these objectives.

  • Tree Planting - A Success!
