Patchy environments and species survival: Chipmunks in an agricultural mosaic

Chipmunks were studied in woods separated by farmland and connected by fencerows. Local extinctions of chipmunks from individual woods were readily recolonised by animals from other patches. Fencerows formed critical connections among woods. A minimum area for considering population survival include...

Description
Summary:Chipmunks were studied in woods separated by farmland and connected by fencerows. Local extinctions of chipmunks from individual woods were readily recolonised by animals from other patches. Fencerows formed critical connections among woods. A minimum area for considering population survival includes several woods and interconnecting fencerows. Such landscape mosaics should be the elementary units in much conservation planning and management.
