In Aydıncık, the number of trees per sampling plot varied from 28 to 86 with a
mean value of 57.4 (±21SD). The average tree height and diameter in the whole
Aydıncık sampling area were 586.7 (±368.8 SD) and 14.9 cm (±12.6 SD),
respectively. There were significant differences in average diameter and height of
trees between sampling plots (Table 3). While the highest averages were in the
sampling plot M7, the lowest ones were in the M8. On the other hand, correlations
of symptom incidences with tree size (Table 4) were not significant, with the
exception of the negative correlation between tree diameter and foliage symptoms.
The highest canker incidence was in the M5 plot (52.3%), followed by the M8,
M4, M9, M3 plots (range approximately 40-50%). The canker incidence (7.7%) as
well as the other assessed symptoms had the lowest values in the M6 plot. The
highest incidence of top dieback, crown dieback, resin exudation, and foliage
symptoms was in the M9 (23.5%), M4 (18.1%), M8 (66.2%) and M10 plots
(51.0%), respectively. Insect damage was the most frequent in the M8 plot (53.8%)
and occasional in the M1 plot (3.6%).
