However

The Hunter Becomes the Hunted
  • With governments assistance, freelancers/wolfers
    are paid to hunt wolves.
  • 1869-1880 five wolf sightings in Yellowstone
  • 1914 1,000,000.00 (18 M today) in wolf
    bounties
  • the value of their hides and their easy
    slaughter with strychnine-poisoned carcasses have
    nearly lead to their extermination."
  • Yellowstone Superintendant Philetus
    Walter Norris in 1880

12
Lacy Act of 1894
  • Various animals all across the nation, such as
    the passenger pigeon, were on the brink of
    extinction.
  • The Lacy Act of 1894 (passed in 1900) was created
    to protect wildlife from this threat. This
    cracked down on the killing, transporting, and
    selling of deceased animals.
  • Wolves "a decided menace to the herds of elk,
    deer, mountain sheep and the pronghorn.every
    effort will be madeto exterminate the wolf.
  • - Colonel Lloyd Brett, 1915 State
    of the Park Address

Process of Elimination
Being shot by park rangers and freelance
wolfers Eating carcases that have been covered
with strychnine or cyanide poison Killed while
trying to rescue a captured pup

Some Much Needed Comic Relief

Where da Wolves???
  • 1914-1926 136 Yellowstone wolves eliminated
  • 1923 last Yellowstone wolf nest is destroyed
  • 1926 two lone pups become the last intentionally
    killed wolves in Yellowstone.
  • 1926 last confirmed wolf sighting at Yellowstone
    until reintroduction

16
YellowstoneWe Have a Problem
  • Around the 1930s, many people realized that
    eradicating wolves from the Yellowstone area may
    have been a mistake.

1. Morality issues playing God, murder. 2.
Negative impact on the ecosystem. Ex Elk
populations of the northern elk winter range
doubled from 1914 1932. Larger
Population - overgrazing - damage to vegetation
erosion Starting in 1935, the park began
controlling the number of elk, pronghorn, and
even bison via shooting and trapping.
Survival of the Fittest
17
Improvements w/ Room for Improvement
  • Fish and Wildlife Coordination Act of 1934.
    Congress demanded that federal agencies ponder
    the effects of their actions on wildlife
    populations and develop a wildlife conservation
    program.

Class Discussion
  • Do you have a fear of wolves? If so, why?
  • Do you believe that wolves should be reintroduced
    to Yellowstone National Park?
  • Assuming reintroduction takes place, do you
    believe that nearby ranchers should be
    compensated for livestock lost due to wolves?
  • Would your answers to the previous questions
    remain the same even if you lived right next to
    Yellowstone and possibly owned livestock?

Reintroduction Introduction
  • 1944 Wolf reintroduction to Yellowstone becomes
    a dream for biologist Aldo Leopold.
  • 1975 Search for remaining wolves in Yellowstone
    ends in failure.
  • 1987 Northern Rocky Mountain Wolf Recovery Team
    is created by the U.S. Fish and Wildlife Service.
  • 1987-1989 Environmental Impact Statement for
    Yellowstone wolf reintroduction.
  • over 130 meetings spanning the entire
    nation people from every single US state as
    well as 40 additional countries comment on the
    situation
  • more than 160,000 comments shatter the EIS
    remark record

21
Time for Some Action
  • January 12, 1995. Eight wolves are brought down
    to Yellowstone from Canada. Six days later,
    eight more wolves follow.
  • Before being released into the park, they are
    kept in one-acre enclosures to prevent them from
    trying to return to Canada.
  • March 21 the wolves are released into the park.

22
Time Time for Some Time for Some Action
  • Population of wolves ranged from 9 months to five
    years of age. Breeders were specifically
    included.
  • 1996 Seventeen additional wolves become the last
    imported Yellowstone wolves to date.
  • Radio collars were attached to enable tracking.

23
Responding to Ranchers
  • Prediction 12 cows and 40-50 sheep per year
  • Actual 139 sheep and 19 cattle for 1995-2000
  • Defenders of Wildlife compensates ranchers who
    lose animals to wolves
  • Big, bad wolves can legally be harassed and even
    shot under certain circumstances

24
Success Story
  • The 31 imported wolves were sufficient to produce
    a Yellowstone-size population.
  • Even though more than 300 wolves populate
    Yellowstone today, less than 100 have died since
    the reintroduction. Of these deaths, more than
    half were due to illegal shootings.
  • Various other benefits (survival of the fittest,
    supplier of food, biodiversity, healthier
    vegetation and earth).

Sixty Years Later
  • "I have watched the face of many a newly
    wolfless mountain, and seen the south- facing
    slopes wrinkle with a maze of new deer trails. I
    have seen every edible bush and seedling
    browsedI have seen every edible tree defoliated
    to the height of a saddlehorn... I now suspect
    that just as a deer herd lives in mortal fear of
    its wolves, so does a mountain live in mortal
    fear of its deer. And perhaps with better cause,
    for while a buck pulled down by wolves can be
    replaced in two or three years, a range pulled
    down by too many deer may fail of replacement in
    as many decades." - Aldo Leopold
