Distribution of cavity trees in midwestern old-growth and second-growth forests

Abstract: Abstract:We used classification and regression tree analysis to determine the primary variables associated with the occurrence of cavity trees and the hierarchical structure among those variables. We applied that information to develop logistic models predicting cavity tree probability as a function of diameter, species group, and decay class. Inventories of cavity abundance in old-growth hardwood forests in Missouri, Illinois, and Indiana found that 8-11% of snags had at least one visible cavity (as visually … Show more

“…Dead trees may contain significantly more cavities per tree than occur in live trees (Fan et al 2003), thereby providing habitat features for foraging, nesting, roosting, hunting perches, and cavity excavation for wildlife, from primary colonizers such as insects, bacteria, and fungi to birds, mammals, and reptiles. Most cavity nesting birds are insectivores, which help to control insect populations.…”

“…They are twice as likely to be cavity trees as living trees (Fan et al 2003). But not all standing dead trees are large enough to support larger nesting species.…”

“…Other softwood species groups contained the largest total number of standing dead trees, predominately ponderosa pine, but cottonwood and aspen species groups had the highest density of standing dead trees on South Dakota's forest land. Compared to the number of live trees, the number of standing dead trees is relatively small, but they typically contain significantly more nest cavities per tree than occur in live trees (Fan et al 2003). Standing dead trees provide areas for foraging, nesting, roosting, hunting perches, and cavity excavation for wildlife, from primary colonizers such as insects, bacteria, and fungi to birds, mammals, and reptiles.…”
