Potential Impact of the Southern Pine Beetle on Red-Cockaded Woodpecker Colonies in the Georgia Piedmont
Thirty-four red-cockaded woodpecker colonies were studied in the Georgia Piedmont to (1) determine the stand, site, and tree characteristics associated with active colonies, (2) rate the susceptibility of colony stands to southern pine beetle attack, and (3) estimate the probability of beetle attack (risk) and potential for spot spread (hazard) over a projected 30-year period. The colony stands contain mature and overmature trees of predominately loblolly pine sawtimber on soils and sites favorable for tree growth. The susceptibility of these stands to beetle attack is generally low. Estimated timber losses resulting from the probability of attack and potential spot spread are also low. Predicted number of trees killed is strongly influenced by combinations of risk, hazard, and size of southern pine beetle populations. Mature stands can be managed to reduce southern pine beetle damage and establish forest conditions favorable to the red-cockaded woodpecker. South. J. Appl. For. 12(3): 194-199.
