Wildlife Fundamentals Approaches to Wildlife Management: 1) Preservation (“hands off”) 2) Conservation (“use wisely”) 3) Management (“manipulate”)

Wildlife Fundamentals Goals of management: 1) population increase 2) population decrease 3) maintain population

Wildlife Fundamentals Goals of management: 1) population increase 2) population decrease 3) maintain population 4) harvest population on sustained yield basis

Wildlife Fundamentals • Single-species vs. Ecosystem Mgt • Coarse-filter vs. Fine-filter adaptive resource management: given current scientific understanding, 1) implement mgt. strategy, but 2) monitor effects and adjust

Habitat • Habitat from an evolutionary perspective • Species distribution relative to habitat dist’n

Habitat • Habitat from an evolutionary perspective • Species distribution relative to habitat dist’n • Climatic events • Pleistocene Epoch & dist’n of modern species • Evolutionary underpinnings • Adaptation & Evolution for habitat

Concept of Habitat Selection • Wildlife perceiving correct configuration of habitat needed for survival

Concept of Habitat Selection • Wildlife perceiving correct configuration of habitat needed for survival – differences based on age/experience/chance? – hierarchy to decision process • Niche concept (time/place/functional role) & habitat selection
