Use selective harvesting/logging instead of clearcutting Bird Conservation

A replicated study in deciduous forest in 1998 in Algonquin Provincial Park, Ontario, Canada (Jobes et al. 2004), found that white-throated sparrow Zonotrichia albicollis, chestnut-sided warbler Dendroica pensylvanica, and mourning warbler Oporornis philadelphia were significantly more abundant in stands recently (1-5 years previously) subject to single-tree selection harvest than in other treatments (logging 15-20 years previously or controls). Ovenbird abundance was approximately 50% lower in stands logged either recently or 15-20 years previously than in controls. Management was designed to mimic natural small-scale disturbances that create forest gaps. In June-August 1998, birds were surveyed in: 24, 1-5 years post-harvest stands; 23, 15-20 years post-harvest stands; and 24 stands subject to no harvest for over 30 years. Shrub and slash cover was highest in recently logged stands and appeared important in influencing bird species composition.
