Designation:
Area:
Image The rounded Ogilvie Mountains and broad sparsely forested valleys characterize LMU 3. (YG photo)
Land Status Non-Settlement Land, VG Settlement Land (S-56A/D, S-44A)
Objectives
  • Ecological integrity is maintained.
  • Sustainable economic development that supports the local economies.
  • Land use activity does not significantly impact movement and habitats of caribou.
Rationale for Designation
  • Adjacency to the Dempster Highway may allow development to occur more readily with less access-related impacts.
  • Limited wilderness tourism activity reduces potential conflict between industrial and tourism sectors.
  • Landscape characteristics make cumulative effects monitoring more effective in limiting impacts on habitat.
  • Moderate mineral potential with good access.
  • Portion of the Kandik oil and gas basin.
  • The high value of this unit for the Porcupine caribou herd, Dall’s sheep, and the people that hunt them calls for a limited scale of industrial development, thus meriting a Zone III designation.
Biophysical Setting
Setting An area of tundra-like plains and mountains lying between the Blackstone Watershed to the east and Upper Ogilvie Watershed to the west.
Ecoregions North Ogilvie Mountains and corner of Eagle Plains.
Bioclimate Zones Taiga Wooded, Taiga Shrub and Alpine.
Ecological Resources
Significant Wildlife and Fish Habitats
Caribou High value winter habitat of the Porcupine and Hart River herds. Extensive concentrated and general use areas for the Porcupine herd.
Moose Narrow bands of high habitat suitability along valley bottoms and smaller tributaries; generally low late winter habitat suitability elsewhere.
Marten Variable winter habitat quality, with significant pockets of moderate-high value habitat.
Sheep Areas of highly suitable winter habitat with documented (TK, big game outfitters, scientific) habitat use.
Fish Fish presence likely in lower gradient streams and main rivers; some known fish occupancy and spawning sites. Winter overflow, open water and surface groundwater indicate good overwintering potential.
Grizzly Bear Mostly moderate habitat suitability in low to mid elevations; high in riparian areas and subalpine zones. TK of a good denning area.
Peregrine Falcon High potential for peregrine falcon foraging and nesting near Ogilvie River.
Birds (General) High value waterbird habitat in riparian areas; low to moderate breeding bird species richness; high number of species of conservation concern.
Vegetation Edge of a national hotspot for plant endemism. Alpine plants, low-mid elevation dry herb, shrub, and coniferous forests, mid-subalpine shrub, riparian communities.
Wetlands, Lakes and Riparian Areas Broad swath of oxbows and riparian habitat along Ogilvie River.
Permafrost Extensive high water content permafrost expected for flatter pediments/plateaus.
Special Features Some mineral licks. Several possible wildlife passes.
Heritage, Social and Cultural Resources
Heritage Resources Cabins (TH). Culturally important places for TGFN, TH, and VGFN. North-South TH heritage routes.
Palaeontological Resources The Bouvette Formation; Road River Group: Ogilvie Formation and Michelle Formation sedimentary rocks in this area have known fossil localities and high potential for further discoveries.
Economic Development
Transportation and Access The Dempster Highway lies at the eastern boundary. Some old unclassified trails; a few airstrips of unknown status.
Traditional Economy TH traditional harvesting and wildlife area, and big game/fur-bearing locations.
Recreation and Tourism Near the Dempster Highway there may be some unusual front-country tourism opportunities. Little tourism potential beyond the Dempster Highway Corridor.
Forestry Little potential for forestry.
Big Game Outfitters and Trapping Reynolds Outfitting Ltd. and Blackstone Outfitting Ltd.; some high value hunting.
Oil and Gas Resources Part of the Kandik basin is within this unit. This basin is considered to have low development potential.
Mineral Resources Approximately 40 quartz claims; some moderate zinc-lead potential; moderate general mineral potential.
Special Management Considerations
  1. The proposed right-of-way for the Dempster Highway lateral pipeline runs along the eastern boundary.
  2. Major River Corridor management directions apply along the Ogilvie River.
  3. Subsequent Dempster Highway sub-regional land use plan may apply to the eastern part of the unit – Dempster Corridor to be managed consistent with IMA Zone III objectives.
