Abstract
Provision of suitable sites for red-cockaded woodpecker (Picotdes borealis) cavity excavation is essential for successful management of the woodpecker. To evaluate internal characteristics of pines used by the woodpecker, we increment-cored longleaf pines (Pinus palustris) to determine heartwood diameter, sapwood thickness, and presence of fungal heartwood decay at 1.3, 6.0, 9.0, and 12.0 m aboveground in 53 red-cockaded woodpecker cavity trees and 53 similar control pines in eastern Texas. Red-cockaded woodpecker cavity trees had thinner sapwood and greater heartwood diameter at all heights than did control trees (P 100 years and did not occur with any regularity until pines were >120 years.
