Invasive Species


Six exotic organisms are present within the area and are impacting or have the potential to impact refuge lands. 

They are the feral horse (Equus caballus); feral hog (Sus scrofa); Asian clam (Corbicula fluminea); common carp (Cyprinus carpio); nutria (Myocaster coypus); and the gypsy moth (Lymantria dispar). Exotic plants that threaten refuge resources include the common reed (Phragmites australis) and alligatorweed (Alternanthera philoxeroides).


The feral horse presence on Currituck National Wildlife Refuge is a controversial issue due to the impact they have on habitat and resources protected for birds.
