Abstract :

Protection of biodiversity is considered one of the global concerns and it needs to manage forest as a complex ecosystem and its vital role in conserving biodiversity have been widely acknowledged. The microhabitats of tree habitats were accurately determined based on the scale lines in a selective manner and the method selected by Lario et al. The measurement parameters including slope, height, moisture content, temperature, light, and soil texture were measured and consequently the environmental factors affecting micro-habitats were investigated using Pc-ordwin software version 4.5 and multivariate analysis (CCA) test. The results showed that in the control parcel, temperature was directly related to light, slope, height, and soil texture, and the average of light, height, soil and positive correlation in this parcel is more than managed parcel, while in the managed parcel it is opposite. The tree microhabitats in the managed and unmanaged parcels have been created under different environmental conditions. According to the results of the CCA and depending on the type of management measures, the forest can be directed towards the type of management by increasing or decreasing the mentioned environmental factors.
