A feral horse is a free-roaming horse of domesticated stock. As such, a
feral horse is not a wild animal in the sense of an animal without
domesticated ancestors. However, some populations of feral horses are
managed as wildlife, and these horses often are popularly called "wild"
horses. Feral horses are descended from domestic horses that strayed,
escaped, or were deliberately released into the wild and remained to survive
and reproduce there. Away from humans, over time, these animals' patterns of
behavior revert to behavior more closely resembling that of wild horses.
Some horses that live in a feral condition but may be occasionally handled
or managed by humans, particularly if privately owned, are referred to as
"semi-feral".
Feral horses live in groups called a band, herd, harem, or mob. Feral horse
herds, like those of wild horses, are usually made up of small bands led by
a dominant mare, containing additional mares, their foals, and immature
horses of both sexes. There is usually one herd stallion, though
occasionally a few less-dominant males may remain with the group. Horse
"herds" in the wild are best described as groups of several small bands who
share a common territory. Bands are usually on the small side, as few as
three to five animals, but sometimes over a dozen. The makeup of bands
shifts over time as young animals are driven out of the band they were born
into and join other bands, or as young stallions challenge older males for
dominance. However, in a given closed ecosystem (such as the isolated
refuges in which most feral horses live today), to maintain genetic
diversity, the minimum size for a sustainable free-roaming horse or burro
population is 150–200 animals. semi-feral horses 1 semi-feral horses
Feral horse populations
Horses which live in an untamed state but have ancestors who have been
domesticated are not true "wild" horses; they are feral horses. There are no
known truly wild horses in existence today. The best-known examples of feral
horses are the "wild" horses of the American west. When Europeans
reintroduced the horse to the Americas, beginning with the arrival of the
Conquistadors in the 15th century, some horses escaped and formed feral
herds known today as Mustangs.
Australia has the largest population of feral horses in the world, with in
excess of 400,000 feral horses. semi-feral horses 2 semi-feral horses The
Australian name equivalent to the 'Mustang' is the Brumby, feral descendants
of horses brought to Australia by English settlers. semi-feral horses 3

In Portugal, there are two populations of free-ranging feral horses, known
as Sorraia in the southern plains and Garrano in the northern mountain
chains. There are also isolated populations of feral horses in a number of
other places, including Sable Island off the coast of Nova Scotia,
Assateague Island off the coast of Virginia and Maryland, Cumberland Island,
Georgia, and Vieques island off the coast of Puerto Rico. Some of these
horses are said to be the descendants of horses who managed to swim to land
when they were shipwrecked. Others may have been deliberately brought to
various islands by settlers and either left to reproduce freely or abandoned
when assorted human settlements failed.
More than 400 feral horses live in the foothills of Cincar mountain, between
Livno and Kupres, Bosnia and Herzegovina, in an area of approximately 145
square kilometres (56 sq mi). These animals, which descend from horses set
free by their owners in the 1950s, enjoy a protected status since 2010.

A modern feral horse population (Janghali ghura) is found in the
Dibru-Saikhowa National Park and Biosphere reserve of Assam, in north-east
India, and is a herd of approximately 79 feral horses descended from animals
that escaped army camps during World War II. semi-feral horses 6 semi-feral

In North America, feral horses are descendants of horses that were
domesticated in Europe, although many ancient, prehistoric subspecies now
extinct did evolve in North America. While there are similarities shown in
certain genes of both modern and fossil North American horses, they are not
believed to be members of the same species. semi-feral horses 7 semi-feral
horses In the western United States, certain bands of horses and burros are
protected under the Wild and Free-Roaming Horses and Burros Act of 1971.
Modern feral horses
Modern types of feral horses that have a significant percentage of their
number living in a feral state, even though there may be some domesticated
representatives, include the following types, landraces, and breeds:

In the United Kingdom, herds of free-roaming ponies live in apparently wild
conditions in various areas, notably Dartmoor, Exmoor, and the New Forest.
Similar horse and pony populations exist elsewhere on the European
continent. These animals, however, are not truly feral, as all of them are
privately owned, and roam out on the moors and forests under common grazing
rights belonging to their owners. A proportion of them are halter-broken,
and a smaller proportion broken to ride but simply turned out for a while
for any of a number of reasons (e.g., a break in training to allow them to
grow on, a break from working to allow them to breed under natural
conditions, or retirement). In other cases, the animals may be
government-owned and closely managed on controlled reserves.

Population impacts
Feral populations are usually controversial, with livestock producers often
at odds with horse aficionados and other animal welfare advocates. Different
habitats are impacted in different ways by feral horses. Where feral horses
had wild ancestors indigenous to a region, a controlled population may have
minimal environmental impact, particularly when their primary territory is
one where they do not compete with domesticated livestock to any significant
degree. However, in areas where they are an introduced species, such as
Australia, or if the population is allowed to exceed available range, there
can be significant impacts on soil, vegetation (including overgrazing), and
animals that are native species. semi-feral horses 3 semi-feral horses
If a feral population lives close to civilization, their behavior can lead
them to damage human-built livestock fencing and related structures.

compete with domestic livestock, particularly on public lands where multiple
uses are permitted, such as in the Western United States, there is
considerable controversy over which species is most responsible for
degradation of rangeland, with commercial interests often advocating for the
removal of the feral horse population to allow more grazing for cattle or
sheep, and advocates for feral horses recommending reduction in the numbers
of domestic livestock allowed to graze on public lands.
Certain populations have considerable historic or sentimental value, such as
the Chincoteague pony that lives on Assateague Island, a national seashore
with a delicate coastal ecosystem, or the Misaki pony of Japan that lives on
a small refuge within the municipal boundaries of Kushima. These populations
manage to thrive with careful management that includes using the animals to
promote tourism to support the local economy. Most sustained feral
populations are managed by various forms of culling, which, depending on the
nation and other local conditions, may include capturing excess animals for
adoption or sale. In some nations, management may include the
often-controversial practice of selling captured animals for slaughter or
simply shooting them. semi-feral horses 13 semi-feral horses Fertility
control is also sometimes used, though it is expensive and has to be
repeated on a regular basis. semi-feral horses 14 semi-feral horses
