PRINCIPLES OF WILDLIFE MANAGEMENT

Benefits of Wildlife Landscaping

There are many benefits for wildlife landscaping at schools such as:

  • 4-H Wildlife Stewards School
    4-H Wildlife Stewards School
    Environmental Middle School
    Outdoor learning laboratory
  • Fosters student participation in solving local environmental issues
  • Improves habitat for local wildlife
  • Increases diversity/pest control

Key concepts:

  1. Four basic needs of wildlife
  2. Limiting factor
  3. Carrying capacity
  4. Succession
  5. Fragmentation
  6. Diversity
  7. Arrangement

First concept: The four basic needs of wildlife

  • Food
  • Water
  • Cover
  • Space

    Food for Wildlife

    • Plants provide natural food sources
    • Native plants are recommended
    • Provide sources of food year round
    • Supplement with bird feeders if desired

    Water for Wildlife

    • Water features for wildlifeMost important habitat feature
    • Provide sources of water year round
    • Bird baths, ponds, creeks, wetlands are good examples

    Cover is a habitat requirement that prevents waste of energy

Space

    • Home range is the area used by an animal for all its activities
    • Territory is defined as all or part of a home range defended to exclude competitors
Swallow Bluebird

Tree swallows are tolerant of other birds nesting nearby
and will often nest in loose colonies.

Western Bluebirds defend large areas for nesting. They like to be at least 300 yards from other cavity nesting birds.

Second concept: Limiting factor

  • This is the habitat requirement that is in shortest supply
  • The limiting factor prevents the wildlife population from growing
  • Food, water, and cover can usually be increased
  • Space usually cannot be increased

Third concept: Carrying capacity

  • This is the number of a given species that a habitat can sustain
  • Carrying capacity can be increased by managing for a limiting factor
  • Long-term improvements include planting natural sources of food and shelter

Fourth concept: Succession

  • Succession is the replacement of one biological community with another
  • Different species of wildlife occur at all stages of succession
  • You can increase wildlife diversity by providing multiple stages of succession

Fifth concept: Fragmented landscapes

Edge Habitat
Edge Habitat
Corridor

Two considerations:

  • Edges
  • Corridors

Edges

    • Habitat edges or ecotones are the transition zones between two or more plant communities
    • Many species use edges

Corridors

    • Habitat connecting other isolated patches of habitat
    • Provides for movement of organisms
    • Larger corridors provide habitat for more species

     

Sixth concept: Habitat diversity

Diversity can be classified in two ways:

  • Species – different plant species and ages
  • Structural – vertical, horizontal, and unique features

    Increase structural diversity

    • Vertically – layering herbs, shrubs, trees
    • Horizontally – create a variety of habitat types using successional stages
    • Unique features – snags, logs, rock walls, and brush piles

Seventh concept: Arrangement

  • Arrangement is providing food, cover, and water in close proximity to one another
  • Go for the natural look- avoid planting in rows
  • Consider direction of prevailing winds

Key things to remember

  • Wildlife need food, water, cover, and space
  • Diversity creates habitat
  • Remove invasive species
  • Plant natives
  • Have fun
