Assateague wild horses
The National Park Service has completed its March 2019 population census of the wild horses on Assateague Island.

The total population of the Maryland herd is currently 76 horses (21 stallions and 55 mares). There were no births or deaths documented during this census.

The National Park Service completes a full census of the horse population in Maryland six times per year, in February, March, May, July, September, and November. Managed as a wildlife population, the Assateague horses are free to roam over approximately 27 miles of the barrier island and can be difficult to find at times.

During each census, horses are identified by their distinguishing characteristics, mapped, and counted. Individual horses that are not observed during multiple census periods are presumed dead. The census’ purpose is to monitor the herd’s overall population dynamics in support of the long-term fertility control program initiated in 1994.
