Relationships between stand structure and bird species richness in the Isparta-Golcük Nature Park forest
2015
Osmanoglu, T.
This study aimed to explore the relationships between bird species richness, accepted as an important indicator of biodiversity, and stand structural characteristics. In the 25 sample plot chosen in the Golcuk Natural Park, six forest stand characteristics were determined including Mean tree height, Gini coefficient, Shannon index, Mixing index, Dominance index, Aggregation index. Bird species richness was calculated using a point counting method by visiting 10 times the plots. The relationships between these structural indices and bird species richness were determined by spearman correlation analyses. No relationship was found as a result of the analyses. Therefore, it was concluded that in addition to stand diversity, the sizes and geographic distribution of forest stands should take into consideration for estimating bird species richness. In the study, stand characteristics were also divided into three categories based on the index values. Then, the relationships were determined between three categories and each bird species. Some bird species depending on their habitat requirements were associated with some diversity categories.
