Due to the lapse in federal appropriations, this website will not be updated until further notice.

Any entry onto Refuge System property during this period of federal government shutdown is at the visitor's sole risk. Please read this important updated message about the closure of National Wildlife Refuge System facilities during the shutdown, and refer to alerts posted on individual refuge websites for the status of visitor facilities and previously scheduled events that may still occur during the shutdown.

Delmarva Fox Squirrel Sightings

Delmarva Fox Squirrel

Have you seen one of these? We are mapping the sightings of the Delmarva fox squirrel. The Delmarva fox squirrel has recently been delisted and is no longer classified as a Federally endangered or threatened species. However, monitoring of this species will continue for 10 years to insure it is still doing well. We are mapping the distribution of this animal and are looking for photos or observations you may have made while visiting the refuge. If you have seen a fox squirrel please print the attached sighting report and turn it into the Visitor Contact Station located at 11978 Turkle Pond Road, Milton, DE. 19968, or call 302-684-8419 if you have any questions.

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.
