Relationships Among Forest Management and Spruce Grouse (Falcipennis canadensis) Patch Occupancy and Abundance in Commercially-Managed Forests
Problem Addressed: Decline of spruce grouse populations
Goal(s)/Objective(s): To determine how the maturity, structure, and composition of the commercial forest affect spruce grouse occupancy and abundance.
Key Findings: Forest harvest practices that maintain and promote conifer regeneration should be implemented in both current, and historically, conifer-dominated stands.

Spruce grouse (Falcipennis canadensis) populations are rare or declining across much of the contiguous United States, especially the Northeast region. Despite this fact, the species has no official protection status in Maine other than a closed hunting season. Because commercially managed forests represent > 2 million hectares in Maine, forest harvest practices are likely to influence spruce grouse habitat. We studied patch occupancy patterns of spruce grouse across different forest harvest treatments during the breeding season (May-June) in northern Maine from 2012-2014.
