Land Use Designation
Integrated Management Area, Zone III
Yukon public land and two VGFN S-sites (S-17A and S-19A)
Vuntut Gwitchin First Nation
2,071 km2 (3.4% of Region)
Biophysical Setting (LMU 5)
Remote, rugged mountainous unit with some of highest elevations in region.
North Ogilvie Mountains.
Taiga Wooded, Taiga Shrub and Alpine.
Extensive areas of high elevation sparsely vegetated, rock, herb and shrub; lower elevation valleys contain coniferous forest and shrub; some wetland and limited riparian.
Porcupine River (Bluefish River) and Yukon River (Salmon Fork River).
Extensive areas of high elevation, sparsely vegetated habitats are present in the Keele Range of LMU #5. (CWS photo)

*These are proportional to the size of the LMU, and correspond to table 3-2 of the Approved Plan. They are measured in the % of the LMU that can be disturbed (“Surface Disturbance”) and in km/km2 (“Linear Disturbance Density”).
**These are amounts that can be measured and apply to the whole LMU and would be more familiar to project proponents and regulators. They are measured in km2 of disturbance and in km of linear disturbance (e.g., roads, trails and cutlines).
***How much more disturbance can be added to existing disturbance before the cautionary threshold is reached.
Amount of disturbance relative to the cautionary theshold:
Caribou concentrated use in eastern portion of unit during three seasons - spring migration, fall migration and winter.
Significant habitats in all seasons. High quality habitat in Bluefish River, Bluefish Lake and Salmon Fork River corridors.
Moderate - high quality winter habitat in forested valleys and mountain slopes.
Sheep population (unconfirmed) near Mount Rover.
Potential over-wintering habitat in middle Bluefish River.
Significant furbearer habitat in northern portion of unit.
Wetlands and Lakes
Bluefish and Salmon Fork river corridors contain wetlands. Bluefish and Useful lakes are present.
Bluefish and Salmon Fork river valleys.
Major River Corridors
Heritage, Social and Cultural Resources
VGFN Heritage Routes and Sites
No identified VGFN heritage routes or sites.
Other Heritage and Historic Resources
High cultural values at Useful Lake, Bluefish Lake and Nest Mountain. One documented archaeological site near Bluefish Lake. Potential for caves to be present.
Current Community Use Areas
Bluefish and Useful lakes, and several winter trails.
Transportation and Access
No existing transportation infrastructure.
Winter trapping and subsistence harvesting.
Tourism and Recreation
Low interests and activity.
Oil and Gas Resources
Very low potential.
Aggregate (Gravel) Resources
No identified resources; river gravels or crushed rock offer potential sources.
Special Management Considerations
- High potential for discovery of heritage resources. Numerous limestone caves present.
- Arctic National Wildlife Refuge is adjacent to western border of unit (Yukon-Alaska border). North Yukon
