Ecological Scale and Forest Development: Squirrels, Dietary Fungi, and Vascular Plants in Managed and Unmanaged Forests

By Andrew B. Carey, Janet Kershner, Brian Biswell, Laura Domínguez de Toledo

Summary: Understandingecological tactics and their spatial scales is vital to handling ecosystems for
biodiversity, particularly for species linked to late-seral woodland. We concerned about 2 species of squirrel (Sci-
uridae: northern flying squirrel, Glaucomys sabrinus, and Townsend's chipmunk,Tamias townsendii) in a
cross-sectional survey of controlled and naturalstandsin southwestern Oregon in the course of 1985-89.

We measured plants and abundances of squirrelsat >2,000 pointsin 19 stands in three seral stages.We defined the diets of the squirrels within the stands. We analyzed information at aspect, stand, and degree scales to spot key methods contributing to biodiversity and scales at which emergent houses (synergistic results) appeared.
