| description | Large water reservoir ponds and dams such as those made for various purposes; It is known that the region changes the climate by affecting the climate factors and provides a different climate structure to the region. Therefore, dams and lakes also affect the growth of trees. Uluborlu dam was chosen as the study area for this effect. This study was carried out in Uluborlu watershed dam located in Isparta-Turkey. Uluborlu dam was established during 1977-1984 and water deposition started in 1985. The purpose of this study was to investigate the local climate effects on diameter increments resulted by Uluborlu Dam Lake on the distributed Black pine (Pinus nigra Arn.) forests. Therefore, sampling areas were chosen from two different places namely as dam effect area and control area. Increment cores were taken from 30 Pinus nigra trees using increment borer at breast height (1.30 m) in each sample plots and two increment cores were taken from each tree. Double ocular microscope was used on the measurement and determination of annual diameter increment. Annual diameter increment of trees in dam effect area and control area were compared with independent t test using SPSS 22.0 statistical program. The relationships between annual diameter increment and climatic factors such as temperature and precipitation were evaluated using Pearson correlation analysis. According to results, there is a statistically significant difference between average annual diameter increment in dam effect area and control area and dam influenced forest areas positively with respect to annual diameter increment. The values of the mean annual diameter increment of the trees in dam effect area are greatly higher than trees in the control area. |
