Abstract

Resin flow and tree moisture stress, frequently used as indicators of pine susceptibility to pine bark beetle (Dendroctonus frontalis Zimm.) attack, were measured in loblolly (Pinus taeda L.) and shortleaf (P. echinata Mill.) pines red-cockaded woodpecker [Picoides boreal& (Vieillot)] cavity trees in the Angelina and Davy Crockett National Forests in eastern Texas. No differences in moisture stress were found, whereas resin flow between different types of cavity trees and control or potential trees varied by site and species. It was concluded that effects of red-cockaded woodpecker activity on host tree susceptibility to southern pine beetle will vary by site, tree species, and host tree condition. Forest management activities and general forest health are much more important for the bird’s long-term survival.
