Designation:
Area:
Image explanation Ahvee Mountain is a significant Porcupine caribou herd habitat.
Land Status Yukon public land
Biophysical Setting
Setting Mountainous unit separating Eagle Plains and Old Crow Basin.
Ecoregions North Ogilvie Mountains, Eagle Plains, and Old Crow Basin.
Bioclimate Zones Taiga Wooded, Taiga Shrub, and Alpine (minor).
Habitat Types High-elevation sparsely vegetated areas of herb, shrub, and rock; low-elevation coniferous forest and shrub; minor wetland and riparian.
Watersheds Porcupine River (headwaters of Johnson, Pine, David Lord, and Cody creeks, and Bluefish River).
Ecological Resources
Significant Wildlife and Fish Habitats
Porcupine Caribou Caribou concentrated use in four seasons – fall migration, rutting, winter, and spring migration.
Moose Significant habitats in all seasons. High-quality habitat in upper David Lord, Johnson, and Pine Creek corridors.
Marten Moderate – high quality habitat in forested valleys.
Sheep No known sheep populations.
Fish Identified over-wintering habitat in Porcupine River.
Other Species Significant bear habitat at headwaters of David Lord Creek.
Wetlands and Lakes David Lord and Johnson/Pine Creek corridors contain wetlands.
Riparian Areas David Lord, Johnson, and Pine Creek valleys.
Major River Corridors Porcupine River.
Heritage, Social and Cultural Resources
VGFN Heritage Routes and Sites Old Crow to Whitestone Village and Old Crow to Johnson Creek Village, via White Snow Mountain.
Other Heritage and Historic Resources Significant heritage resource values. Documented archaeological sites.
Current Community Use Areas Sharp Mountain, Lone Mountain, and Johnson Creek.
Economic Development
Transportation and Access Old Crow winter road runs along Johnson Creek valley.
Traditional Economy Winter subsistence harvesting.
Tourism and Recreation Low interests and activity (outside of Porcupine River corridor).
Oil and Gas Resources Overall low – moderate potential; northern margin of unit is in Eagle Plain oil and gas basin.
Mineral Resources High potential in western portion of unit.
Aggregate (Gravel) Resources No identified resources.
Special Management Considerations
  1. Important caribou concentrated use area during several seasons. In the western portion of the unit, Ahvee, Veeshridlah, and Nest (Chii Too Choo) mountains are among the most intensively used areas in the region. Most significant habitats are high–mid elevation, non-forested areas.
  2. Southern boundary is adjacent to Ni’iinlii’njik (Fishing Branch Wilderness Preserve).
  3. Maintain opportunities for community use and subsistence harvesting (winter season).
  4. Existing routing of Old Crow winter road should be maintained.
