The evaluation of wood products for site classes of calabrian pine: A case study for Antalya regional directorate of forestry

The main purpose of this study was to evaluate the wood products of Antalya Regional Directorate of Forestry Calabrian Pines (Pinus brutia Ten.) in pure and natural stands with the site classes. For determining the sample plots some parameters such as age, site class and density (9 age classes, 3 site classes, 3 density rate and 3 replications) were used. Two sample trees were cut down in 216 sample plots and totally 432 trees were examined. Regression analysis was used for investigation of relationships between product variety and diameter at breast height for each site class. As a result of evaluation it was found on 95% between diameter at breast height and timber ratio and standard error was found 5,884. Also, for I., II. and III. site class, this relationship were found 95%, 93% and 92%, and their standard errors were 5,052, 6,990 and 6,759 respectively. An evaluation of pit prop products ratio, the relation between diameter at breast height and pit prop ratio were found 77% and standard error was 0,494; for I., II. and III. site classes these relationships are, 79%, 84% and 85% level, their standard errors were determined to 0,515, 0,385 and 0,418 respectively. There is general evaluation for industrial wood ratio and the result shows that the relation between diameter at breast height and mine pole is 93% and standard error is 2,361; for I., II. and III. site index classes, industrial wood ratio relations are 87%, 71% and 82% level, their standard errors were determined to 0,357, 5,256 and 0,296, respectively.
