Orman Ekolojisinde Odunsu Vejetasyonun Sınıflandırmasına Yönelik Bir Çalışma (Isparta-Yenişarbademli Örneği)

Abstract

This study was carried out to classify woody vegetation in Yenişarbademli forest areas. The vegetation classification is important to biological diversity conservation and sustainability. In the study, 103 sample plots 20 x 20 m size were taken for inventory. In the study area, woody plant species and environmental factors were recorded in the inventory. Cluster analysis and two way indicator species analysis (TWINSPAN) were performed to distinguish vegetation groups in the study. While cluster analysis and two way indicator species analysis were carried out, present/ absence values of plant species were used. By using the cluster analysis distinctions, a relationship analysis between qualities was also applied. Multi-response permutation procedures (MRPP) analysis was applied to the cluster analysis and TWINSPAN results to determine which groups would use the resulting analyzes. The results obtained from MRPP analysis showed that the best option was provided with TWINSPAN used five indicatory species. As a result of TWINSPAN used five indicatory species, THYSAM, CIRARV, BERVUL, JUNOXY and EUPSPP species were identified as discriminating species. The first group represented 51 and the second group represented 52 sample plots. Discriminating species were determined to be species located in high elevation of the study area. As a result of the analysis, the species in the first group is positive indicators while in the second group is negative indicators. As a result, elevation is the most important variable when discriminating species group and indicator species are identified.
