Title

INVESTIGATION THE VEGETATION BIODIVERSITY IN THE MANAGEMENT AND UNMANAGEMENT HEAPS OF PARROTIO–CARPINETUM IN THE NORTH OF IRAN (THE CASE STUDY: SERIES 5 BEHSARA)

Pages

Abstract

 In this research the vegetation BIODIVERSITY of the management and unmanagement heaps of PARROTIO–CARPINETUM has been studied and compared from the viewpoint of species RICHNESS, EVENNESS and SPECIES DIVERSITY indexes in golband forestry project, series 5 BEHSARA. For doing this research sampling was accomplished in the management (under exploitation) and unmanagement (witness) sample parcels which were similar in the habitat condition and vegetation structure. At first, by the use of data collection system with 100 and 150 m dimensions 60 sample plots with 20 and 20 dimensions for studying woody species and 5 one and one microplots in four corners and the center of every plot for studying grassy species were randomly–systematically sampled. After collecting data they were analyzed by past and spss software and independent–samples T test. The results show that the RICHNESS of dendroid and grassy species is in order 10 and 36 in the unmanagement heap and 11 and 50 in the management one, so the RICHNESS, EVENNESS and diversity in dendroid species have no significant difference with each other. In grassy species the significant difference is %99 from the viewpoint of species RICHNESS and shanoon SPECIES DIVERSITY and the sympson SPECIES DIVERSITY and the difference is not significant from the viewpoint of shanoon EVENNESS.
