Assateague Island National Seashore Wild Horse Update – September 2019

Berlin, MD - The National Park Service has completed its September 2019 population census of the wild horses in Assateague Island National Seashore.  There are 76 horses in the Maryland herd, including 22 stallions and 54 mares.  One death was documented and there were no births.

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 purpose of the census is to monitor the overall population dynamics of the horse herd in support of the long term fertility control program that was initiated in 1994.
