The invasion by non-native
species in to an ecosystem threatens the biodiversity, human and animal health,
and can even have economic impacts in a region. The development of transportation has created a global world
in which organisms are offered an opportunity to reach parts they would never
exist in naturally. We are
beginning to understand how fragile the balance of native species in an eco system
is after witnessing havoc created by non-native species.
One
of the only invasive mammals found in the Adirondack Park is hard to define as
non-native because it essentially escaped from our own backyards. Popular TV shows such as American
Hoggers and Hogs Gone Wild focus on the wild hog issue in the south but many
New Yorkers and New Englanders aren’t aware of their presence in the North
East. The hogs terrorizing
farmland in the Champlain Valley are escaped livestock, domestic pet pigs, or
Eurasian boars, which escaped from hunting reserves (adkinvasives.com). Populations have increased due to the
pigs ability to begin reproducing at 6 months and bearing litters of up to 10
offspring (Foderaro). As shown in
the TV shows on A&E and Discovery the pigs can often be aggressive towards
humans, and develop sharp tusks.
The pigs have become pests to local farmers because of their large
appetites which they are known for.
Feral pigs will eat almost anything including native vegetation and
crops, fawns and domestic livestock, as well as low nesting birds and reptiles
(Foderaro).
Farmers
and state officials are eager to eradicate the feral pig population that
threatens the already fragile agriculture of the Adirondacks. The state originally permitted open
season for any hunter with a small game license in the state of New York
(Foderaro). The open season policy
actually elevated the issue of feral pigs as the pigs were learning from failed
trappings of herds and never returning to trap sights again. The act of hunting the pigs actually
further dispersed the population as one or two pigs were being taken down and
others were escaping (Foderaro).
The pigs intelligence has forced the DEC and New York State to prohibit
feral pig hunting so that they can “ensure maximum effectiveness of DEC’s
statewide eradication efforts” (Adirondack Almanac). While it is a very serious threat to viability of
agriculture in New York State, it is hard not to chuckle at the thought of pink
pigs running around wreaking havoc and outsmarting hunters and farmers alike in
the Adirondack region.

This is insane! I have never heard of this before. Do you know if they cause problems with disease in addition to demolishing crops?
