  • Phylum: Craniata

The grizzly bear (Ursus arctos horribilis), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. 

General Information

Key Habitat Features

Closed forest sites near higher quality forage areas, used for security habitat (females and cubs) and day bedding.

Avalanche chutes, subalpine meadows, marsh and swamps are important for forage.

High elevation areas with sloped, dry and stable soil conditions which remain frozen in the winter are used for denning sites in the interior of BC. Commonly north facing slopes.

Dens not often reused but bears come to the same area to dig a new den.

Coastal bears den under large old trees or within large tree cavities. 

Objectives

Minimize disturbance and maintain habitat so dens continue to be readily used.

Maintain physical integrity of dens and potential denning habitat for future use by bears.

Maintain desired plant communities and key habitat features.

Planning and Operational Measures

All Activities

Identify key habitat features using appropriate measures (i.e. QP direction, desktop review, field confirmation, etc) and plan activities within the operating area accordingly.

Time works such that they occur outside of the critical timing window.

Apply the appropriate survey and setback requirements for WHFs within identified habitat. (Refer to section 1.9 of the EPMG for additional guidance on WHFs).

All Activities

Undertake construction and operation of oil and gas activities in a manner that minimizes impacts to desired plant communities and key habitat features.

 

Timing considerations when working within identified habitat:

 

Avoid disturbance and/or clearing activities during the critical timing window from November 1 to April 15.

 

Linear Features

All

Upon completion of the activity, undertake the following measures to encourage re-establishment of the pre-disturbance ecological trajectory:

deactivate unnecessary access corridors,

undertake measures to control access,

promote natural or assisted regeneration.
