Survival analysis of a critical resource for cavity-nesting communities: Patterns of tree cavity longevity

Edworthy, Amanda; Wiebe, Karen L.; Martin, Kathy


Tree cavities are a vital multi-annual resource used by cavity-nesting birds and mammals for nesting and shelter. The abundance of this resource will be influenced by the rates at which cavities are created and destroyed. We applied the demographic concepts of survival and longevity to populations of tree holes to investigate rates of loss for cavities in three tree species, as well as how characteristics of nest trees, habitat type, and species of excavator affected the persistence of tree...[Show more]
