How It Effects The Ecosystem
Importance
of Wolves!
Facts
Killing wolves affects the entire ecosystem. All species
depend on the ecosystem for their survival. When
the wolves are taken away, other animal
populations increase.
When deer and elk become to large for the habitat,
they overgraze and destroy the plant base, make
the habitat not suitable for other species.
Wolves pose no threat and play a precious role by
maintaining natural balance.
Wolves help keep the coyote population in check,
along with by preying on young or elderly, sick or
injured, weak or unfit.
Wolves also have an hierarchy in their own pack. The
omega eats the left over from the other wolves. This
also helps thin out the weaker ones for hunting and
increases the stronger ones for survival.

Yellowstone
Park
Scientist Smith, Peterson, and Houston claimed
that wolves need to be restored because
“every species that was in the park when the
white men first came to the region is still
there, except one (the wolf) {2003}. If wolves
are to become extinct someday, it should be
by the hand of Mother Nature and not by
the hand of humanity.
