"The long-term survival of free-ranging animal populations requires that a certain amount of optimum habitat be available. Recommendations regarding the type and amount of habitat are based in part on the premise that an animal will "prefer" habitats that fulfill its life requisites." P. 316
"…fishers did not use cover types in proportion to their availability…The mixed hardwoods with conifer closure greater than 50% and the open/brush cover type contributed the most…" p. 323
It is implied that "fishers prefer habitats with trees greater than 27 cm dbh. The percent tree canopy closure selection function increased with increasing canopy closure, exceeding 1.0 at 47%. Fishers were also found to prefer an over-story tree canopy with deciduous closure between 14 and 76%." P. 325
Pages 322 and 324 have graphs indicating the use and suitability of different habitat types for fishers.
