Mark's and Jack's Island Natural Area Preserve
Mark's and Jack's Island Natural Area Preserve is a Natural Area Preserve located in Accomack County, Virginia. Both islands support Chesapeake Bay beach habitat, as well as various types of marsh, shrub, and forest vegetation. Many species of birds can be found in the preserve's wetlands, and numerous plant species live in the marsh. Loblolly pine and black cherry may be seen along the tops of some old dunes. The beaches provide a home for the northeastern beach tiger beetle.
