Document Summary
Cant do good conservation unless you understand the behaviors and activity"s of the species. Home range: the area an individual animal uses for obtaining resources: food, mates, and ability to care for its young. Whats the area/habitat they need to survive in. Estimating and understanding a home range barn owl example: movement paths- how it uses area and when goes back to nest, land use types (pasture, farmland) alalfa fields or pastures. Repeatedly locating an animal and circumscribing the area it uses . Body weight and trophic level: bigger animals have bigger home ranges because more resources. If that"s what you feed on then have to have bigger home range: the higher you feed on trophic level the larger home range cause food more rare. Ex- columbia spotted frog, salamander, bighorn sheep, oystercatcher. Mongolian gazelles (grass is not predictable fires and rain) Everything/all year long-tigers in nepal-don"t touch other females areas.
