Area:
Image Deciduous forests, and steep escarpments are found along the upper Vittrekwa River in the eastern portion (top). Gentle mountains interspersed with valleys carpeted with alpine vegetation characterize the western portion (bottom). (CWS photos)
Land Status Non-Settlement Land
Objectives
  • Wilderness character is maintained.
  • Archaeological resources are protected and integrity of First Nation cultural practices is maintained.
  • Unfettered movement and habitat use of Porcupine caribou herd, Dall’s sheep and other large mammals.
  • Habitats are maintained for water birds and fish, along with the watershed and hydrological functions upon which they depend.
  • Wilderness tourism activities linked the Dempster Highway that are consistent with the objectives above and don’t require significant infrastructure.
Rationale for Designation
  • Borders a Conservation Area in the Gwich’in Land Use Plan.
  • Porcupine caribou herd uses this area for habitat and as an important migration route.
  • Extensive wilderness hiking opportunities within a short distance from the Dempster Highway.
  • Includes a Yukon Key Wetland complex.
  • Several traditional travel routes traverse the unit. Other culturally important places also exist.
  • A small and isolated population of Dall’s sheep that may be at risk of decline is found here.
  • A regionally unique and culturally important Dolly Varden spawning runs up the Vittrekwa River to spawn.
  • The steep escarpments that overlook the Vittrekwa and adjacent Road rivers are underlain with permafrost and therefore are especially susceptible to surface disturbance. This susceptibility is predicted to increase as a result of climate change. Resulting slope failures could result in hydrological changes catastrophic to the Vittrekwa River wetlands.
  • Low to moderate mineral potential, with no current claims. Part of the Peel Plateau and Plain basin with lower oil and gas potential.
Biophysical Setting
Setting Unglaciated, sparsely forested mountains and foothills dividing Eagle Plains from the Peel Plateau giving way to perched wetlands and an adjacent riparian strip on the NWT border west of the Peel River.
Ecoregions British Richardson Mountains and Peel River Plateau
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 generally low predicted habitat potential for the Porcupine herd. Exposed slopes are important foraging areas, especially in high snow years.
Moose High habitat use and quality along creeks and around wetlands.
Marten Concentrated moderate to high winter habitat suitability around wetlands and 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 Fish likely present on lower gradient streams; some winter open water areas, one known sea-run fish spawning site on Vittrekwa River.
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 Low – mid elev. shrub and conifer forest, subalpine shrub and alpine exposed rock.
Wetlands, Lakes and Riparian Areas Several large lakes and wetland complexes and hundreds of scattered wetlands; key wetland area (YG) around Vittrekwa River and Lakes. Forms the upper watersheds of Vittrekwa, and Road Rivers.
Permafrost Extensive high water content permafrost expected. Wetlands perched above incised valleys and stable slopes rely on intact permafrost.
Special Features One documented wildlife pass and one possible pass.
Heritage, Social and Cultural Resources
Heritage Resources High concentration of VG and TG archaeological sites. Several TG culturally important places. Travel route through Road River from Kit Creek; route along unnamed creek from Dempster to Peel River.
Palaeontological Resources
Economic Development
Transportation and Access One old winter roads; a conceptual access route has been identified in this unit from Dempster Hwy to Road River. Several seismic lines or trails.
Traditional Economy TG seasonal land use and traditional harvesting and wildlife areas.
Recreation and Tourism High value hiking in with access from Dempster Highway. Snowmobiling and wildlife viewing.
Forestry Little potential for forestry.
Big Game Outfitters and Trapping No registered concessions.
Oil and Gas Resources Peel Plateau and Plain basin with low potential in the flatter eastern portion of unit.
Mineral Resources Generally low mineral potential.
Special Management Considerations
  1. Dempster Corridor management directions apply near the Dempster Highway.
  2. Subsequent Dempster Highway land use plan may apply near the Dempster Highway.
