Transcript of The Pros and Cons of Wolfs being reintroduced

PRO or CON?
There can be many prime reasons why the reintroduction of the wolf may be a good or bad idea.
Since their return wolves
have benefited their ecosystem by regulating prey numbers
and movements allowing stream bank habitats to recover,
reducing densities of coyotes, and providing food for
scavengers.
THE PROS
Why Reintroduction is a Good Choice.
Wolves play a vital role in maintaining the health and
sustainability of the landscape in the Yellowstone
region and our western lands.
Ecological Benefits
Without fear of wolves, elk over browsed the vegetation inhibiting the growth of
new trees. Since the reintroduction of wolves in Yellowstone, elk spend
more time in the safety of thick cover or on the move.
THE CONS
The Reintroduction of Wolves.
Since the reintroduction of wolves, farmers everywhere have noticed a reduction in their yearly revenue, due to the fact of wolves attacking their livestock.
In the absence of wolves, coyotes became a top predator in the
ecosystem, but they are not large enough to regulate elk, deer,
and moose populations.
The Next Predator
Wolves and Scavengers
Scavengers, such as ravens, eagles, and bears, also benefit heavily from the
return of wolves. Wolf kills provide scavengers with an important source of
protein, particularly in winter.
Animals Who Benefit

Yellowstone cutthroat trout and other native fish
Moose
Waterfowl (ducks, geese, trumpeter swans)
Songbirds (such as warblers, wrens, and thrushes)
Small mammals (such as beavers, muskrats,
and other rodents)
Insects, amphibians, and countless other species
Conclusion
By regulating wildlife herds and reducing the
prevalence of diseases, revitalizing riparian areas, reducing coyote densities,
providing food for scavengers, and indirectly improving conditions for a host
of other species, wolves play an essential role in maintaining the ecological
health and integrity of the landscape.
