Phylum: Craniata

Class: Aves

Order: Passeriformes

Family: Parulidae

Scientific: Setophaga virens

• Mature and old growth mixed wood forest (aspen and deciduous with some conifer component (white spruce/spruce) and good canopy closure) with lush herbaceous layer, free mid canopy space and dense low shrubby understory; key forb/herb species (baneberry, rose, highbush, cranberry, fireweed, mosses, kinnikinnick, peavine and bunchberry).
• Mature mixed wood forested adjacent to riparian reserves.
• Mature and old deciduous-leading forest patch sizes >2 ha.

• Minimize disturbance during the breeding season.
• Maintain nesting habitat throughout all seasons.
• Maintain desired plant communities and key habitat features.

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.

 

• Where an application area is within a NEBC WHA for Black-throated Green Warbler, please refer to the EIMS summary for that Order. Proponents are required to adhere to the guidance provided in that summary, including any relevant timing considerations.
