Exploring the Atlantic Wild Horse Trail with Bonnie Gruenberg
The wild horses of Assateague Island National Seashore are bold. Too bold. They brazenly wander into the campsites in search of good grazing and any tidbits that they can beg from obliging humans. They walk under clotheslines and step on beach towels. They sniff and sometimes sample food cooking inches from open fires, and excavate scraps from the cooling coals. Itchy foals view most human contraptions as potential scratching posts, from barbecue grills to truck bumpers. They tear large holes in screen houses and walk on in, even if there is nothing inside. Campers shoo them away with the loud clanging of a spoon against a pot. It does not frighten them, but signals the animals that they are not welcome and should take their activities elsewhere.
Many visitors cannot understand that these friendly, curious animals pose any threat to them. Although the ponies are largely unafraid of people, they are not tamed or trained. Bites and kicks are commonplace. Often, the perpetrator was a horse who was standing docilely moments before the scene turned ugly. Signs and pamphlets warning of danger do not stop naive visitors from seeking close contact with them. Some feed the horses from their cars and, in effect, train them to stand in the road waiting for handouts. Horses are killed by drivers who did not expect to see them on the pavement. Additionally, rangers impose fines of $175 per incident upon visitors caught feeding, petting, or approaching within 10 feet of horses or other wildlife,
Some believe that the original Assateague horses swam to shore from the wreck of a Spanish galleon, but there is no clear evidence to support this theory. Most likely, free-
In 1968, the National Park Service took possession of Assateague, acquiring the holdings of landowner Paul Bradley and the 21 ponies that grazed it. These foundation animals—nine stallions and 12 mares—became the nucleus of the Maryland resident herd. All the horses on the Maryland end of the island descend from this population, and no outside horses have been introduced since the National Park Service took over its management.
Every organization that manages wild horses must decide how much human intervention is appropriate. Management options run the gamut from keeping hands off, as with the herd at Cumberland Island NS, to providing food, shelter, reproduction assistance, and health care, as with the herd on Ocracoke, North Carolina. With the most intensive management, they are indistinguishable from domestic horses, trading off freedom for better health and security. Managing a herd with minimal intervention allows greater freedom, but greater exposure to disease, parasites, weather extremes, and inbreeding.
The National Park Service has targeted a herd size of 80–100 animals for Assateague. It manages the horses of the Maryland portion of Assateague as wildlife. Horses have no predators and roam the park as protected and brazen and self-
When their numbers increase beyond the targeted population range, environmental damage can occur, and horses may consume or destroy resources needed by other species, some of them endangered. In 1993 the Park Service began to use immuncontraceptive vaccines to decrease the birth rate for Assateague horses. Each mare was allowed to deliver one foal, then was vaccinated against pregnancy for the rest of her life. Unburdened of the demands of repeated pregnancy and lactation, contracepted mares live an average of 9 years longer than mares allowed to reproduce at will.
Currently, the Assateague herd is genetically healthy, and the Park Service maintains records of their lineage. In the future, horses may be added to the Maryland herd if the gene pool shrinks or if disease or disaster decimates the population. These additions would be chosen from other East Coast barrier island populations. The horses from these herds are genetically similar to the Assateague horses, yet different enough to revitalize the gene pool. They are also well adapted to life on a barrier island, and so are likely to survive in the new environment.
Until the early 1900s, Assateague was part of a long peninsula passing through Maryland into Delaware. The Great Hurricane of 1933 opened Ocean City Inlet, and thereafter Assateague has been an island. Littoral currents, produced by waves that hit the beach at an angle, have since attempted to fill it with sand, but dredging and painstakingly maintained jetties maintain the waterway.
In the 1930s, Assateague was surveyed as a potential site for a national seashore, but the plan never coalesced. In the 1950s, Leon Ackerman and a group of investors bought and surveyed 15 miles of Assateague oceanfront property north of the Virginia line and laid out more than 2,000 residential and commercial lots. Builders erected more than 200 structures, and paved a road, Baltimore Boulevard, to the Virginia state line. They dug deep channels for marinas and for mosquito control. When revenue was insufficient to fund a bridge to the mainland, the developers strategically donated a sizable tract of land to the state of Maryland to create Assateague State Park, and the state funded the Verrazano bridge. Assateague was on its way to becoming another bustling resort city—until the Ash Wednesday storm of 1962.
This powerful nor'easter destroyed almost every home on the island. Sheets of seawater literally picked up houses and dumped them in the marsh. Two new inlets cut across the island. Baltimore Blvd. was ripped apart. (Large broken chunks of roadway remain along the "Life of the Dunes" nature trail in the seashore.)
After this reality check, developers and home owners alike wondered if perhaps the barrier island was too unstable to support a resort community. Ideas to turn the whole island into a national seashore revived, and the seashore took shape in 1965.
Assateague Island National Seashore presents a unique opportunity to observe the activities of horses in the wild. The visitor center has excellent programs, exhibits, and educational materials available to familiarize visitors with the complex social behavior of these fascinating animals.
