| Land Status | Yukon public land |
| Biophysical Setting | |
| Setting | Remote mountainous unit with sub-arctic conditions. |
| Ecoregions | British Richardson Mountains. |
| Bioclimate Zones | Taiga Shrub, Alpine, and Tundra (minor). |
| Habitat Types | High elevation sparsely vegetated, herb, shrub, and rock; low elevation coniferous forest and shrub; minor wetland and riparian. |
| Watersheds | Porcupine River (Bell, Little Bell, and Waters rivers, headwaters of Driftwood River). |
| Ecological Resources | |
| Significant Wildlife and Fish Habitats | |
| Porcupine Caribou | One of the most significant caribou concentrated use areas in the region. Porcupine herd may be present in at least five seasons, including summer, fall migration, rutting, winter, and spring migration. Calving occurs infrequently in the northern portion of the unit. |
| Moose | Significant seasonal habitats along river corridors. Bell River corridor supports some of the highest winter moose densities in Yukon. |
| Marten | Low–moderate winter habitat. |
| Sheep | Status uncertain; significant sheep habitats identified in adjacent LMU #4C. |
| Fish | Potential over-wintering habitat in Bell and Waters Rivers. |
| Other Species | Muskoxen can be found in the area; significant bear habitat. |
| Wetlands and Lakes | Very few. |
| Riparian Areas | Bell and Waters rivers, and several large tributary streams. |
| Major River Corridors | None |
| Heritage, Social and Cultural Resources | |
| VGFN Heritage Routes and Sites | No identified VGFN routes or sites. Traditional use and culturally significant area for Gwich’in First Nations. |
| Other Heritage and Historic Resources | Documented archaeological sites. |
| Current Community Use Areas | Limited use; most activities occur in lower Bell River corridor (LMU #4C). |
| Economic Development | |
| Transportation and Access | No existing transportation infrastructure. A conceptual access route has been identified in this unit1. |
| Traditional Economy | Limited activities. |
| Tourism and Recreation | Low interests and activity. |
| Oil and Gas Resources | Low or no potential; northern margin of the Eagle Plain oil and gas basin. |
| Mineral Resources | Low or moderate potential. |
| Aggregate (Gravel) Resources | No identified resources; river gravels or crushed rock offer potential sources. |
| Special Management Considerations | |
