Wildlife Society
  • This course deals with wild animals and their
    relationships with humans
  • Wildlife Any animals living in a wild state
    and by consensus include birds, mammals,
    reptiles, and amphibians (vertebrates except for
    fish)

8
Different views of Wildlife
  • Wildlife means different things to different
    people
  • Traditional view Species that are hunted or
    trapped, game
  • In last 25 years other vertebrate species,
    non-game

9
Changing Reasons for Wildlife Management
10
Definition of Wildlife Management
Wildlife management is the application of
ecological knowledge to populations of
vertebrate animals and their plant and animal
associates in a manner that strikes a balance
between the needs of those populations and the
needs of people (Robinson and Bolen 1999)
11
Wildlife management (or conservation) involves
three basic management approaches
  • Preservation by allowing nature to take its
    course without human intervention.
  • Direct manipulation of animal populations by
    trapping, shooting, poisoning, and stocking.
  • Indirect manipulation of animal populations by
    altering the vegetation or water that is present.

Goals of Wildlife Conservation
  • Information Needs for Wildlife
  • Conservation
  • Animal and habitat considerations
  • Assessment of past and current populations
  • Reproductive success
  • Determine major limiting factors
  • How to manage the population(s)

14
  • Era of Abundance 1600-1849
  • Native wildlife abundant-especially- bison,
    grizzly bear, elk, pronghorn, waterfowl,
    passenger pigeon
  • Animals associated with early succession were far
    less common than now (e.g. deer, quail)
  • Humans did not believe animal populations could
    disappear

15
Era of Abundance (1600-1849) (continued)
  • Predator control began
  • First closed season on wildlife (deer)

Grizzly hides

16
  • Era of Overexploitation 1850-1899
  • Coincided with accelerated human settlement of
    North America
  • Increased technological developments (weapons,
    railroad)
  • Market hunting flourished
  • Loss of bison, prairie chickens, eastern grizzly,
    wolves, passenger pigeon

17
Era of Overexploitation 1850-1899 (continued)
  • Yellowstone Nat. Park established
  • First bag limits established
  • Supreme Court case Geer vs Connecticut
    established public ownership of wildlife

18
  • Era of protection 1900-1929
  • Drastic declines of wildlife and other resources
    alarmed the public
  • Legal protection was the primary tool of wildlife
    conservation
  • State game and fish departments established
  • Still a negative attitude toward predators

19
Era of protection 1900-1929 (continued)
  • Lacey Act passed in 1900
  • Federal control over migratory birds (treaty
    perogative)
  • First national wildlife refuge established (by
    executive order)

20
  • Era of game management 1930-1965
  • Recognized that we needed to know more about
    ecology and biology of animals
  • Wildlife conservation oriented toward game
    animals
  • Contributions of Aldo Leopold --Game Management

21
Era of game management 1930-1965
Increased public funding of conservation efforts
Example of Ding Darlings cartoons on the plight
of wildlife in the 1930s.
Current (1930s) practices
22
Era of game management 1930-1965 (continued)
  • Duck stamps authorized by Congress to raise funds
    for wetland preservation.
  • First North American Wildlife Conference held
  • Federal government plays major role in wildlife
    conservation

23
Quote from first issue of the Journal of Wildlife
Management (1936) The policy of the Wildlife
Society embraces the practical ecology of all
vertebrates and their plant and animal
associates and while emphasis may often be
placed on species with special economic
importance, wildlife management along sound
biological lines is also a part of the greater
movement for conservation of our entire native
fauna and flora.
24
Early Examples of Exploitation
  • Pleistocene Overkill Hypothesis
  • Early humans killed relatively large numbers of
    large mammals mammoths, mastadons

25
Early Examples of Exploitation
  • American Bison once numbered over 60 million in
    North America.
  • By 1890, there were only about 300 left

26
Early Examples of Exploitation
  • There may have been as many as 2.2 billion
    Passenger Pigeons in North America
  • By 1900, they were extinct as a wild species.

27
Early Examples of Exploitation
  • Various species of wildlife have become extinct
    or extirpated in the past 200 years in North
    America
  • Examples Plains Grizzly, Carolina Parakeet,
    Heath Hen, Eastern Elk.

28
Early Examples of Exploitation
  • Problem of excess harvesting- for example, market
    hunting

29
Examples of Exploitation
  • Predator control a major problem from 1700s to
    mid-20th century.
  • Wildlife managers considered native predators
    bad - bounty on coyotes

30
Examples of Exploitation
  • A growing problem is that of exotic animals and
    plants.
  • Big problem on islands

31
  • Era of Environmental management
  • 1966-present
  • Many landmark laws passed
  • NEPA, CEQ, EPA, ESA
  • Recognition that we need to look at the
    environment from a more holistic approach
  • Prominence of endangered species conservation

32
Era of Environmental management 1966-present
(continued)
  • Endangered Species Act (ESA) passed (3 versions
    1966,1969,1973)
  • More interest in ecosystem approaches
  • Clinton NW Forest Plan adopted
  • Habitat Conservation Plans (HCPs)

33
Examples of Success in Wildlife Conservation
  • American Bison
  • From the surviving 150 individuals, there are now
    over 30,000 bison in many different herds.

34
Examples of Success in Wildlife Conservation
  • Whooping Crane
  • In 1941, there were only 23 birds left.
  • In 2000, there were 190.

35
Examples of Success in Wildlife Conservation
  • Wood Duck
  • Once a common, hunted species, but because of
    over harvesting and loss of cavity-nest sites, it
    became rare.
  • Provided artificial nest sites (boxes) and
    protection. Now common again.

36
Examples of Success in Wildlife Conservation
  • The Wild Turkey- a very large bird that suffered
    from over harvesting and loss of habitat.
  • Habitat restoration control of hunting has
    resulted in many recovered populations.

37
Examples of Success in Wildlife Conservation
  • The Trumpeter Swan- a very large bird that
    suffered from over harvesting and loss of
    habitat.
  • Total protection has resulted in many recovered
    populations.

38
Examples of Success in Wildlife Conservation
  • The white-tailed (Eastern U.S.) and mule deer
    (W. of Cascades to Dakotas) suffered from over
    harvesting and loss of habitat.
  • Habitat restoration better protection has
    resulted in many recovered populations.

39
Maybe too successful?
  • Buck white-tailed

White-tailed doe and fawns
40
Examples of Success in Wildlife Conservation
  • The elk (wapiti) suffered from over harvesting
    and loss of habitat.
  • Habitat restoration better protection has
    resulted in many recovered populations.

41
Examples of Success in Wildlife Conservation
  • The gray wolf has been persecuted for centuries
  • Change of attitudes has made restoration efforts
    possible (e.g. Yellowstone NP)
  • Success remains to be seen but depends on human
    attitudes
