Edge effects and predation in artificial nests.

Abstract

Creation of edges within continuous forest often results in higher rates of predation closer to forest edges than within forest interior. We tested the generality of this pattern using artificial nests created at five sites in Cheboygan County, northern Michigan. Each site contained nine nests, placed 5m, 15m, and 30m from a defined edge. Tracking stations were used to detect tracks of predators. We discovered no relationship between predation and distance from forest edge.
