Comparison of woody plants diversity in protected and non-protected areas of Arasbaran forests
Using species richness, Shannon-Wiener diversity and Simpson indices, diversity of woody species in protected and non protected areas of Arasbaran forests were studied and compared in this research. Two forest stands with similar floristic and physiognomic situation were selected by using of aerial...

Then tree species were recorded in 92 transects, each with 30 meter lengths, which was established in 150×300 m grid in the forest stands of the protected area and in a similar way in the non protected area.
