Threats identified within this subunit include wildfire and wildfire suppression; climate change; tree mortality from drought, disease, and insect infestation; vegetation management; exposure to toxicants;
potential for effects associated with small population size; disease and predation; and vehicle collisions.
Special management considerations or protection measures to reduce or alleviate the threats may include: 1
Implementing forest management practices, especially the use of prescribed fire, that reduce the risk of catastrophic wildfire and improve habitat resiliency in and adjacent to fisher habitat; 2 minimizing habitat disturbance, fragmentation, and destruction at the stand scale, homerange scale, and landscape scale from vegetation management activities through the use of conservation measures; 3 preventing, locating, and remediating trespass marijuana grow sites and other sources of toxicants; and 4 improving the efficacy of existing road-crossing structures and installing new wildlife road crossings on major roadways. Federal lands in this subunit are managed under the Sierra Nevada Forest Plan Amendment USFS 2004, entire, the Giant Sequoia National Monument Management Plan USFS
2012, entire, and the Sequoia and Kings Canyon National Parks General Management Plan NPS 2012, entire.
Subunit 3B: Homes Nose-Paradise Peak Subunit 3B consists of 9,369 ac 3,791
ha of lands in the Sierra Nevada mountains in Tulare County, California.
This subunit is located north and west of Homes Nose, east of Case Mountain, and south of Paradise Peak, and it crosses the East Fork Kaweah River.
Lands within this subunit include approximately 9,283 ac 3,757 ha; 99
percent managed by NPS Sequoia and Kings Canyon National Parks and 86 ac 35 ha; 1 percent managed by BLM.
General land use within this subunit includes forest management e.g., timber harvest, fuels reduction, hazard tree management, forest restoration, prescribed fire, grazing, recreation, and management for protection of natural resources.
Subunit 3B is occupied by the fisher and contains the physical and biological feature essential to the conservation of the species. This subunit has high predicted habitat value due to mature forest conditions and numerous giant sequoia groves and other mixed-

Subunit 3C: Muir Grove Subunit 3C consists of 88,082 ac 35,645 ha of lands in the Sierra Nevada mountains in Tulare and Fresno Counties, California. This subunit lies north of Paradise Peak, extending northwest across the North Fork Kaweah River to the Kings River Canyon. A sinuous arm of the unit extends east along the southern edge of the Kings River Canyon to approximately Cedar Grove. Lands within this subunit include approximately 44,793 ac 18,127 ha; 51
percent managed by USFS Giant Sequoia National Monument, Sequoia National Forest, and Sierra National Forest and 40,733 ac 16,484 ha; 46
percent managed by NPS Sequoia and Kings Canyon National Parks. Also, there are 386 ac 156 ha; less than 1
percent in State ownership State Lands Commission and 2,170 ac 878 ha; 2
percent in private ownership. General land use within this subunit includes forest management e.g., timber harvest, fuels reduction, hazard tree management, forest restoration,

Subunit 3C is occupied by the fisher and contains the physical and biological feature essential to the conservation of the species. This subunit supports high fisher occupancy rates Tucker 2020, pers. comm., suggesting it supports relatively high population densities Spencer et al. 2015, p. 46 compared to other areas within its range, which provides resiliency for the DPS.
