  1. Habitat Management

  2. Habitat Selection? • Based on instinct • Evolution limits to certain area • Animals make choices based on “range of tolerance” • Wildlife Managers take advantage of these choices

  3. Edge • Contact area between two types of habitat

  4. Types of Edge • Inherent Edge- • Occurs without management • Induced Edge- • Controlled by management

  5. Edge Effect (Aldo Leopold) • Edges have greater: • Diversity of life • Number of organisms • Important for game management

  6. Ecotone • Transition area where two different habitats blend together

  7. Types of Habitat Destruction • Perforation • Dissection • Fragmentation • Shrinkage • Attrition

  8. Effects of Habitat Destruction • Increased: • Isolation • Number of “generalist” species • Decreased: • Biodiversity • “Specialist” species • Large range species

  9. Species With Increased Extinction Risk • “Specialists” • Large space requirements • Low reproductive rate • Economic value • Found in few areas
