Rare Plant Inventory at Assateague Island National Seashore 2023 - Open Format Dataset

The unique environmental conditions found on Assateague Island National Seashore (ASIS) are reflected in the dynamic continuum of habitats stretching from ocean to bay, including beaches, dunes, grass and shrublands, freshwater wetlands, maritime forests, and salt marshes. The diverse barrier island landscape provides habitat for a multitude of specialized plant species, at least 46 of which have been classified as rare, threatened, or endangered (RTE). To identify the current locations of RTE species in these areas, surveys were conducted during spring and fall 2023. Timed meander surveys were conducted along roadways and parking lots, and along access roads and around dwellings where demolition is proposed. Recommendations include fencing to protect the most vulnerable species from disturbance during construction and demolition activities, and flagging populations of more abundant species to increase visibility and minimize disturbance during construction. Future monitoring is recommended.
