Reports on changes in terrestrial vertebrate communities from pre- to post-harvest in experimentally created buffer strips (20, 100, 200, and 800 m wide) in a boreal mixedwood forest in Alberta, Canada. Focus on the utility of forested buffer strips as reserves for forest species in managed landscapes; Observations on abundance of small mammals, amphibians, and forest-dependent bird species; Conclusion that 20?100 m buffers would not serve as reserves for forest songbirds in managed landscapes.
