The most famous, and perhaps the most popular, of Sable
Island's fauna are the wild horses. Although access to the island is
restricted - both by location and by regulations - the horses are
well-known, and are of great interest, culturally and scientifically.
The Sable Island horses have been featured in several documentaries and
numerous books and magazine articles, and they were the subject of an
exhibition at the Equine Museum of Japan in Yokohama (1994), and a
photography exhibition in New York City (Roberto Dutesco, 2002). This
population of horses has been the topic of doctoral research (Welsh
1975), and long-term studies have been underway since the mid-1980s
(e.g. Lucas et al. 1991).
The romantic notion that Sable Island horses are
descended from shipwreck survivors persists. The present-day horses,
however, are descendants of animals brought to Sable Island during the
late 1700s. Introductions of small numbers of domestic horses occurred
sporadically during the 1800s and early 1900s. A thorough account of the
history of the Sable Island horses is provided by Barbara Christie
(1995).
There are a number of other populations of free-ranging
horses found throughout the world, some on islands, some in inland
regions. Other island horses include those on the barrier islands of
Assateague and Shackleford, both off the east coast of the USA. Most
populations of wild horses consist of feral animals (i.e. domesticated
animals that have returned to the wild). Such horses are wild in the
sense that they are generally free to roam as they please, to form
various social organizations, to reproduce, and to forage for their own
food and water, and to survive or succumb to disease, weather and
predators. However, many of these free-ranging populations are exposed
to some form of interference by people - fertility control, culling,
round-ups, adoption programs etc. The Sable Island horses are among the
few wild horse populations that are entirely unmanaged: they are not
subject to any kind of interference. Since 1961, the Sable Island horses
have had legal protection under the Sable Island Regulations of the
Canada Shipping Act.
The number of horses on Sable Island generally ranges
between 200 to 350. There have been occasional calls for control or
removal of the horses. Indeed, the protection now provided by the Sable
Island Regulations was a response to heated controversy arising in 1960
when the federal government announced that the horses were to be taken
off the island. Since then, the few advocates of control or removal of
the horses typically cite "humanitarian" concerns, or complain that the
horses, being an `introduced species' must be having a negative impact
on the island. Thus far, however, such arguments for control or removal
of the horses have been fraught with serious misconceptions and lack of
information.
Although the horses are presently protected by the
Sable Island Regulations, this protection exists only so long as the
horses and their island habitat are effectively monitored. Since 1801,
when the life-saving stations were established, there has been a
continuous government presence on Sable Island. Now the future of Sable
Island and the Station is in question, and the Government of Canada is
considering various options - one of which is to close the Station, thus
ending 200 years of full-time human presence and stewardship. This
option would put not only the horses, but all the island's flora and
fauna at serious risk.
