6 HABITAT TYPE VS. HABITAT? Habitat Type: the type of vegetation association in an area or to the potential of vegetation to reach a specified climax stage. (Daubenmire, 1968) 6

8 HABITAT Habitat Type: the type of vegetation association in an area or to the potential of vegetation to reach a specified climax stage. (Daubenmire, 1968) Habitat: the resources and conditions present in an area that produce occupancy including survival and reproduction by a given organism. (Hall et al., 1997) 8
