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.

Retain unfragmented mature forest patches >2 ha, within identified Black-throated Green Warbler habitat.

Within identified habitat, avoid activity within riparian areas consisting of mature coniferous or mixed wood forest.

Avoid sensitive areas such as nest sites and foraging habitat.

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

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 June 1 to July 31.
