Area:
Image explanation LMU #2 is a diverse unit. Pictured is the confluence of Bluefish and Porcupine rivers. Second Mountain, part of the Old Crow Range, can be seen in the background.
Land Status VGFN Settlement Land (VG R-01A, R-10A, R-11A, and many S-sites) and Yukon public land.
Biophysical Setting
Setting Diverse unit includes rolling hills, low mountains, and extensive pediments.
Ecoregions Old Crow Basin, Old Crow Flats, Davidson Mountains, and North Ogilvie Mountains.
Bioclimate Zones Taiga Wooded, Taiga Shrub, and Alpine.
Habitat Types Low–mid elevation coniferous forest, shrub and wet herb; high elevation sparsely vegetated, herb, shrub and rock; significant wetland (LMU #2C) and riparian (Porcupine).
Watersheds Porcupine River (Bluefish and Old Crow rivers, and Caribou Bar, David Lord, and Big Joe creeks).
Ecological Resources
Significant Wildlife and Fish Habitats
Porcupine Caribou Caribou concentrated use in four seasons – summer, fall migration, rutting, and spring migration. Calving occurs infrequently.
Moose Significant habitats in all seasons. Porcupine River and Upper Caribou Bar Creek most significant areas.
Marten Low – moderate quality winter habitat.
Sheep No known sheep populations.
Fish Identified over-wintering habitat in Porcupine River; potential over-wintering habitat in Old Crow River.
Other Species Spring and fall waterbird staging on Porcupine River.
Wetlands and Lakes Few wetlands and lakes outside of major river corridors. Upper Caribou Creek and Bluefish River confluence most significant wetland areas.
Riparian Areas Porcupine and Old Crow rivers; Caribou Bar Creek.
Major River Corridors Porcupine and Old Crow rivers.
Heritage, Social and Cultural Resources
VGFN Heritage Routes and Sites Many routes and sites (see Map 2, Appendix 1).
Other Heritage and Historic Resources Many documented heritage and archaeological sites. Rampart House Yukon Historic Site designation pending.
Current Community Use Areas Most areas used for subsistence harvesting and travel, focused on Porcupine River corridor.
Economic Development
Transportation and Access Crow Mountain gravel quarry access road.
Traditional Economy All seasons and activities, including forest harvesting. LMU #2 receives the highest level of community use in the North Yukon Planning Region.
Tourism and Recreation High values and interests; low activity levels. Area around Old Crow and Rampart are the most important resources.
Oil and Gas Resources Overall low potential; portion of unit is in the Old Crow oil and gas basin.
Mineral Resources High potential; highest potential in Old Crow Range.
Aggregate (Gravel) Resources Few identified resources; river gravels and crushed rock offer potential sources.
Forest Resources Large stands of riparian spruce limited to the Porcupine River corridor and some tributary streams. Important fuel-wood resource for Old Crow.
Special Management Considerations
  1. North Yukon Land Withdrawal prohibits land disposition and resource exploration activities.
  2. Important caribou concentrated use area during multiple seasons; Porcupine caribou cross Porcupine River at this unit during fall and spring migration.
  3. Maintain opportunities for community use and subsistence harvesting.
  4. Old Crow Community Area noted for community infrastructure requirements.
