Designation:
Area:
Image Rolling mountains interspersed with valleys carpeted with shrubs and scattered trees characterize much of LMU 10. (CWS photo)
Land Status Non-Settlement Land, TG Yukon Land (R-07FS)
Objectives
  • Wilderness character is maintained.
  • Community cultural activities practiced without significant disturbance.
  • Unfettered movement and habitat use of Porcupine caribou herds, Dall’s sheep, and other large mammals.
  • Wilderness tourism activities within their carrying-capacity.
  • Archaeological, palaeontological and other heritage resources are identified and studied.
Rationale for Designation
  • Concentrated or moderate use by the Porcupine caribou herd in recent decades over much of the unit.
  • Important N-S migration route for the Porcupine caribou herd.
  • A small and isolated population of Dall’s sheep that may be at risk of decline.
  • Rare and/or endemic plants and high number of species of nesting bird of conservation concern.
  • The Peel River Watershed Advisory Committee and the Gwich’in Interim Land Use Planning Board concluded that the Richardson Mountains should be a candidate for protection.
  • High concentration of VG and TG archaeological sites.
  • No oil and gas potential, low-moderate mineral potential, and few quartz claims.
Biophysical Setting
Setting Unglaciated, sparsely forested mountains lying north of Aberdeen Canyon, and separating Eagle Plains to the west from the Peel Plateau to the east.
Ecoregions British Richardson Mountains
Bioclimate Zones Alpine, Taiga Shrub and Taiga Wooded
Ecological Resources
Significant Wildlife and Fish Habitats
Caribou Extensive concentrated and general use areas for Porcupine herd for fall and winter seasons, despite low predicted habitat potential for the Porcupine herd. Exposed slopes are important foraging areas, especially in high snow years.
Moose Generally poor late winter habitat, though ribbons of high value habitat follow creeks.
Marten Generally poor winter habitat suitability, except for extensive high value winter habitat on lower slopes to the south of the unit.
Sheep Large areas of highly suitable winter habitat with documented (TK, scientific) habitat use. However, the population is small and isolated and is at risk of decline.
Fish
Grizzly Bear Moderate to high habitat suitability, especially high in riparian zones.
Peregrine Falcon
Birds (General) Pockets of high value waterbird habitat and in riparian areas; moderate breeding species richness and high concentration of species of conservation concern.
Vegetation High endemism/rarity index. Low – mid elev. shrub and conifer forest, subalpine shrub and alpine exposed rock.
Wetlands, Lakes and Riparian Areas A few scattered wetlands. Forms the upper watersheds of Doll Creek, Trail, and Caribou Rivers.
Permafrost Continuous permafrost is predicted.
Special Features Several documented wildlife passes and possible pass.
Heritage, Social and Cultural Resources
Heritage Resources High concentration of VG and TG archaeological sites. Several TG culturally important places. Travel route from Caribou River to lower Peel River.
Palaeontological Resources
Economic Development
Transportation and Access
Traditional Economy TG seasonal land use and traditional harvesting and wildlife areas; TH fish harvest on Trail River.
Recreation and Tourism
Forestry Little potential for forestry.
Big Game Outfitters and Trapping No registered concessions.
Oil and Gas Resources No potential.
Mineral Resources Approximately 260 quartz claims; low to moderate general mineral potential.
