Mountain beaver (Aplodontia rufa rufa and Aplodontia rufa rainieri)

WHA planning objectives

Maintain known colonies.

Wildlife habitat area

Establish a WHA around currently occupied colonies. WHAs should include the colony plus 50 m.

GWM management objectives

Protect existing burrows and denning animals.
Ensure integrity of burrow system.
Maintain soil and drainage characteristics suitable for burrowing.
Maintain coarse woody debris.

General wildlife measures

These measures must be applied within a WHA approved for the species.

Access

  • Do not construct roads, skid trails or landings unless variance is approved by the district manager and regional fish and wildlife manager. Consult MELP when road maintenance, deactivation or rehabilitation activities on existing roads are required to ensure species requirements are adequately addressed.
  • If skidding is unavoidable, lay out trails before snowfall when burrows are visible.

Silviculture

  • Do not use harvest methods that cause damage to burrows.
  • Do not use mechanical site preparation techniques that will cause damage to burrows.
  • Do not slash burn unless variance is approved by the district manager and regional fish and wildlife manager.
  • Avoid the use of pesticides. Spot treatments with herbicides may be used in exceptional circumstances (e.g., noxious weeds) where it can be demonstrated that the herbicide will not be harmful to the species or habitat being managed.

Landscape unit planning considerations (not mandatory)

Riparian connectivity is expected to provide the principal dispersal avenue, and for A. r. rainieri, retention of forested habitat, regardless of successional stage, may be adequate to preserve populations. For A. r. rufa, threatened by the loss of large blocks of habitat to urbanization, managers should consider the limited dispersal distances noted for the species to date, and ensure that WHAs are not isolated within extensive areas (>500 m) of little or no cover.

Vancouver Island marmot (Marmota vancouverensis)

WHA planning objectives

Maintain occupied habitat.

Wildlife habitat area

Establish a WHA over colonies. The WHA should include a core delineated by the outer perimeter of the colony and a buffer area of a width sufficient to maintain the microclimatic regime of the colony area. Consult the Vancouver Island Marmot Recovery Team to determine this width.

GWM management objectives

Complete protection of existing burrows and denning animals.

Ensure integrity of burrow systems.

Maintain soil and drainage characteristics suitable for burrowing.

General wildlife measures

These measures must be applied within a WHA approved for the species.

Access

  • Do not construct roads or landings. Consult MELP when road maintenance, deactivation or rehabilitation activities are required to ensure species requirements are adequately addressed.

Silviculture

  • Do not harvest or salvage in core area.
  • Single tree or group selection systems may be appropriate in the buffer. The district manager in consultation with the regional fish and wildlife manager will determine whether or not these systems are suitable.
  • Where timber harvesting with ground-based equipment is approved, it should only be conducted with low ground pressure equipment, to avoid causing damage to burrows.
  • Do not use mechanical site preparation techniques that will cause damage to burrows.
