Faculty: Stephen The HARLS-CS provides valuable exploratory capabilities in the area of pre-visual detection of southern pine beetle infestations across pine forests in the South. Opportunities for control of this insect pest (the most serious killer of trees in southern pine forests) are currently limited by aerial detection failures of developing infestations. Infestations become visible as pine foliage in trees newly killed by southern pine beetle fades from green to yellow to a reddish color coincident with increasing moisture stress. If early detection of new infestations becomes possible, environmentally sound control alternatives become possible (Stephen et al. 1997; Stephen and Browne, 2000). Current research on a devastating pest of oak trees in the Ozark Mountains of Arkansas and Missouri, the red oak borer, benefits from the HARLS-CS equipment. Creating hazard models of forest sites and stand at highest risk will be more completely implemented with these image classification methods.
