5 Reasons to save the Delmarva Fox Squirrel

This week’s endangered species is the Delmarva Fox Squirrel (Sciurus niger cinereus)(photo from  For those folks not in the Chesapeake Bay watershed, “Delmarva” is the peninsula that runs along the eastern shore of the Chesapeake Bay;  the Delmarva fox squirrel was historically found all along the Delmarva peninsula.  According to the species recovery plan, it’s now down to just 10% of its historical population (it was listed as federally endangered in 1967).  It is currently found in eight counties on the Eastern Shore of Maryland (all but Cecil) and Sussex County, Delaware and Accomack County, Virginia (from U.S. FWS Species Profile).  What’s causing the decline of this species?  I know I’m sounding like a broken record in these endangered species posts, but once again, the main culprit seems to be habitat fragmentation and loss.

Here are 5 reasons to save the Delmarva Fox Squirrel:

1)  By preserving the forests on which these squirrels depend, we’re also helping many other, less charismatic but equally important, species

2)  The Delmarva fox squirrel population seems to be responding positively to reintroduction attempts (see MD DNR update) – there’s hope!

3)  Species such as the Delmarva fox squirrel, that move and eat seeds and nuts, help to maintain forest ecosystem health and reproduction

4)  Research indicates that these squirrels can survive in a landscape managed for agriculture and sustainable timber harvest

5)  Oh my gosh, how cute are these little guys?
