Home range size of Black-backed Woodpeckers in burned forests of southwestern Idaho


Dudley, Jonathan G.; Saab, Victoria A. 2007. Home range size of Black-backed Woodpeckers in burned forests of southwestern Idaho. Western North American Naturalist. 67(4): 593-600.

We examined home range size of Black-backed Woodpeckers (Picoides arcticus) in burned ponderosa pine (Pinus ponderosa) / Douglas-fir (Pseudotsuga menziesii) forests of southwestern Idaho during 2000 and 2002 (6 and 8 years following fire). Home range size for 4 adult males during the post-fledging period was 115.6-420.9 ha using the 95% fixed-kernel method, and 150.4-766.1 ha using the 100% minimum convex polygon method. Smoothed bootstrap estimates (95%) were 130.0-521.9 ha. Home range sizes were significantly smaller 6 years after fire than 8 years after fire. Each male had from 2 to 8 areas of concentrated use within his home range. We provide recommendations for estimating area requirements of Black-backed Woodpeckers in post-fire ponderosa pine / Douglas-fir forests.
