- Observation Thirteen woody species were recorded in the study area.
- Observation Smilax excelsa had the highest presence in the sample plots, at 39%.
- Observation Rhamnus sp. had the lowest presence in the sample plots, at 0.04%.
- Observation Acer campestre and Viburnum lantana were observed as two index species of the Arasbaran region.
- Observation Viburnum lantana was often found on the western aspect.
- Observation Acer campestre was often found on the eastern aspect.
- Association Slope had no significant main effect on the Taxa, Simpson, Shannon-Weiner and Margaleff indicators.
- Association Aspect had a significant main effect on the taxa index.
- Association Aspect had a significant main effect on the other diversity indicators.
- Association The average of all diversity indicators was higher in the western aspect than in the other aspects.
- Observation Clustering of vegetation composition confirmed the site comparison of diversity indices.
- Recommendation The authors recommend using these diversity indicators in future studies and in monitoring vegetation change.
