Wildlife Values
  • Wildlife is often viewed as a bonus
  • Usually not primary reason for management
  • There is an increasing interest in biodiversity
  • Sum of all species in an ecosystem as well as the
    sum of their function in the ecosystem
  • Wildlife represents two types of inherent value
  • Consumptive value
  • Appreciative value

5
Wildlife Values
  • Consumptive Value
  • Hunting
  • Fishing
  • Fur Trapping
  • These types of recreation are critical to
    wildlife management!
  • Why?

6
Wildlife Values
  • Consumptive Value
  • What do you get from consuming/ harvesting
    wildlife?
  • Food
  • Recreation
  • Life lessons
  • Income
  • Management
  • outcomes

7
Wildlife Values
  • Appreciative Value
  • Non-consumptive
  • Nature viewing
  • Bird watching
  • Nature hikes
  • Outdoor recreation

8
Wildlife Values
  • Consumptive vs. Appreciative
  • Hunting and fishing license sales drive wildlife
    management in the U.S.
  • Not just for game species!
  • Ex. Waterfowl permits help to protect all species
    of waterfowl, not just hunted species
  • Pittman-Robertson Act provides a continuous flow
    of funds for wildlife management and research.
  • Funded by tax on hunting supplies, fishing
    supplies, and gas at marinas

9
Wildlife Values
  • Biodiversity Value
  • Level at which ecosystem is intact
  • All species are important
  • Biomedical value and possible medications
  • How do you place a value on less charismatic
    species in the ecosystem?
  • Determine their value in terms of ecosystem
    services
  • Ex. Beavers as ecosystem engineers
  • How do you put a monetary value on this service?
  • They act as keystone species that produce habitat
    for a variety of lesser organisms

11
Ecological Interactions
  • What does wildlife do for forest ecosystems?
  • Seed dispersal
  • Aids in succession
  • Predation
  • Insect and disease management
  • Management of forest carrying capacity
  • Herbivory
  • Acts as a disturbance and aids in regeneration
  • Soil cycling
  • Earthworms and burrowing rodents

13
Wildlife as Components of Forest Ecosystems
  • Early successional species
  • Groups of plants and animals are specifically
    associated with each successional stage
  • These species are adapted to a specific
    successional stage
  • Ex. White tailed deer browsing on
  • new growth following a low impact fire

14
Wildlife as Components of Forest Ecosystems
  • Mixed-age forest species
  • Some species require a mixed age forest to suit
    their habitat and food needs
  • Allows for various food and habitat types at
    different times of the year
  • Ex. Rocky Mountain elk migrating
  • to lower elevations to escape the
  • winter food shortage in their summer
  • range

15
Wildlife as Components of Forest Ecosystems
  • Old growth forest species
  • These forest species require a unique habitat
    only provided by old growth forests
  • Usually, these species only have a very small
    niche
  • Ex. Northern spotted owl
  • responsible for redirecting the forest
  • management of the Pacific Northwest

16
Wildlife as Components of Forest Ecosystems
  • Edge Habitat Species
  • Species that utilize edge habitat have the
    advantage of a food source and cover habitat in
    close proximity
  • Edge habitat often leads to a congregation of
    predators
  • Ex. Bob-white quail use fields for a
  • food source and the edge for
  • nesting protection

17
Wildlife as Components of Forest Ecosystems
  • Riparian zone species
  • Def Riparian Zones are areas of vegetation that
    immediately surrounds a body of water
  • These areas are usually highly productive due to
    unlimited water and nutrients
  • Ex. Waterfowl use riparian
  • zones for nesting

19
Forest Management and Wildlife
  • Fire suppression and prescribed burning
  • Fires role in forest management is controversial
  • Remember, fire is a natural disturbance that may
    be necessary for some species
  • Fire could be bad or good for a species depending
    on its needs
  • Ex Old growth species would not respond well to
    fire while early successional species would have
    a positive response

20
Forest Management and Wildlife
  • Timber Harvest
  • Timber harvest can benefit early successional
    species
  • Timber harvest can replace fire as a disturbance
  • Forest Fragmentation
  • Usually lowers species diversity / biodiversity
  • Detrimental to species that require contiguous
    old growth forests
  • Ex Northern spotted owl / black bear

21
Forest Management and Wildlife
  • Use of pesticides and herbicides
  • Harmful to many wildlife species
  • Bioaccumulation increases up the food chain
  • Ex led shot used for waterfowl hunting
    bioaccumulated in bald eagles, leading to their
    death
  • Ban of DDT has lead to a resurgence in the raptor
    populations
  • Killing of insects leads to a lack of food for
    predators

23
Wildlife Considerations in Ecosystem Management
  • Managing for biodiversity
  • Threatened and endangered species
  • Regulating habitat loss
  • Maintaining existing habitat
  • Some species require very intricate management
    ideas that involve multiple trophic levels
  • Value of downed woody debris
  • Coarse woody debris increases species diversity
  • This is characteristic of an old growth forest
  • Creating woody debris can help to increase
    biodiversity

24
Wildlife Considerations in Ecosystem Management
  • Ecosystem structure and function
  • Streamside protection
  • Buffer (riparian) zones are created to insure the
    quality of the watershed
  • Protection of stream crossings from logging
    practices (usually skidders) help to keep
    sediment out of the watershed
  • Habitat manipulation
  • Prescribed burns help to regenerate understory
  • Food plots help to increase game species
