ارزيابي توان اكولوژيك دو رويشگاه طبيعي سرخدار در شمال ايران

Ecological capability evaluation of two natural sites of Taxus baccata in the north of Iran.

In this research ecological capabilities (collection of environmental characteristics such as soil, aspect, slope, microclimate and elevation that shows potential of forest area) of Iranian conifersʹ forests were evaluated. "Taxus baccata", in Vaz and Afratakhteh sites forests were studied. Study in three parts of trees, natural regeneration and vegetation was performed. Inventory was performed in 2500 m2 random plots. For analysis of dataʹs, basal area, treeʹs distribution in diameter classes, number of trees in per hectare and height curve were prepared. For vegetation, biodiversity common indices were studied. The results show. Vaz site has better situation in treeʹs distribution in diameter classes, basal area, regeneration, HD index and height curve and it has more amount of biodiversity index.
