N2  - This study was conducted in Atabey Anatolian black pine forestation site affiliated to Isparta Forestry Directorate from 2014 to 2015 in order to reveal the impact of pine processionary moth (PPM), Thaumetopoea wilkinsoni Tams on increment. The study area was exposed to PPM in 2007, while the amounts of increment from 2007 to 2014 were compared. This enabled us to explore the increment losses in trees and their recovery process following the epidemic for normal increment. Increment cores were taken at breast height from 30 individual black pine trees with similar diameter, height, age and density at 2 spots within the study site to represent the whole site while the annual ring widths were measured in micrometer through stereo microscope at the laboratory. The annual increment decreased by 34,6% in the 1st spot and 39,7% in the 2nd spot in 2007 according to the overall average when the epidemic took place, whereas it decreased by 58,3% and 43,1%, respectively, in the following year. Considering that annual precipitation and drought might have had an impact on the increment of trees, the data obtained regarding the increment were compared with the meteorological data, and interpreted. By the end of the study, it was concluded that the increment loses were completely associated with the insect damage, whereas precipitation and drought did not have an impact.
