“Home range size appears directly related to habitat quality.” p. 1

“National Forests will be contributing to the maintenance of viable populations. It may not be possible for a forest to sustain a population by itself. Therefore, the maintenance of old growth and mature habitat management areas will be coordinated between adjacent forests and other land manageent agencies to provide connection of suitable habitat in areas to ensure interaction between individuals and maintain viability throughout their range.” p. 2

Fisher Habitat:
“Preferred habitat is characterized by dense (60 - 100% canopy) multi-storied, multi-species late seral stage coniferous forests with a high number of larger (> 30 inch dbh) snags and downed logs. These areas also include close proximity to dense riparian corridors and saddles between major drainages or other landscape linkage patterns used as adult and juvenile dispersal corridors, and an interspersion of small (<2a.) opening with good ground cover used for foraging . Numerous and heavily travelled roads are not desirable to avoid habitat disruption and/or animal mortality. Occasional one or two lane forest roads with moderate levels of traffic should not limit marten and fisher movements.” p. 2

In high quality habitat, 6,000 acres would be the size of year round home range where 70-80% of the stand structure is mature closed conifer. Riparian areas would be < 1/4 — 1/2 mile from the denning habitat and live tree snags for dens would be >6 per acre and >44dbh. [This information and more is in the table on Pages 4&5]

Marten Habitat:
“Preferred habitat is characterized by dense (60-100% canopy), multi-storied, multi-species late seral coniferous forests with a high number of large (>24 inch dbh) snags and downed logs. These areas also include close proximity to dense riparian corridors used as travelways, and an interspersion of small (<1 a.) openings with good ground cover used for foraging. Numerous and heavily travelled roads are not desirable to avoid habitat disruption and/or animal mortality. Occasional one and two lane forest roads with moderate levels of traffic should not limit marten and fisher movements.” p. 6

In high quality habitat, 1400 acres would be the size of year round home range where >50% of the stand structure is mature. Riparian areas would be <1/4 mile from closed canopy stands. [This information and more is in the table on Pages 7&8.]
