Fair Hill has managed fields to provide nesting habitat for meadow species like Bobolink, Grasshopper Sparrow, and Eastern Meadowlark.

Fair Hill is a 5,656 acre Natural Resources Management Area, where multiple management practices are employed for the maximum use and protection of Maryland's natural resources. Bordered by Pennsylvania to the north and less than one half mile west of Delaware, Fair Hill is known for its pristine fields, woodlands and natural beauty. At one time one of the largest private land holdings in the east, Fair Hill was formerly owned by William duPont, Jr., an avid equestrian rider who acquired the farmland as a means to enjoy riding as well as fox chasing. Fair Hill was purchased by the state in 1975 from Mr. duPont's estate.
