1 Because aspen and birch are typically too small for pileated woodpeckers and barred owls, no focus<br />
species associated with snags, cavity trees, and downed woody material were assigned to this type.<br />
However, because aspen and birch are prone to internal decay, they are valuable but short-lasting<br />
cavity trees for the many species that utilize smaller trees.<br />

Marten and fisher benefit from a variety of structures that provide cover for small mammals that are<br />
their prey, including downed logs, brush, stumps, root tip-up mounds, and other features.<br />
