These findings demonstrate the importance of testing widely accepted ecological classifications and the need to view landscape ecology from the perspective of non-forest wildlife. Thus, management for these declining species should involve providing large patches and minimizing edges. The key implication of this result is that small or irregular patches, dominated by edge, are unlikely to provide suitable habitat for shrubland birds.
#Ecotone edge effects landscape Patch
All 17 species tested had higher abundances in patch centers than along edges, and edge effects were significant for 8 of 17 species. The meta-analysis clearly showed that shrubland birds avoid edges. We analyzed data for 17 species from seven studies that compared the abundances of birds in the interiors and edges of regenerating clearcuts surrounded by mature forest. We used a meta-analysis to test how edges affect the abundance of shrubland birds in early- successional habitats. With populations of shrubland birds declining throughout the eastern United States, the question of whether or not these birds really prefer edge habitats has important conservation implications. Because these birds are assumed to thrive in fragmented, edge-dominated areas, their landscape ecology has received little attention from ecologists. In studies of forest fragmentation, birds of scrubby, early-successional habitats are considered edge specialists.
