چکیده مقاله:

Habitat needs of woody species in terms of distribution is necessary for natural resources management (Modification, Development, Regeneration, conservation, and protection of forests). Data were collected from 96 sample plot using the systematic-random method. The size of the sampling plot was 20 m× 50 m for the tree and layers. In each plot, topographical factors (elevation, slope, aspect) and percent cover of herbaceous and the crown cover of tree species were recorded. Multivariate analysis methods were used to classify and determine the relationship between species composition and environmental factors. The result of the TWINSPAN analysis showed that eight ecological groups were recognized. Amygdalus scoparia and eight herbaceous are indicators of the first group. The ordination results (HRDA) indicated that the topography factors had an influence on the establishment of Amygdalus scoparia species were a slope, elevation, aspect, respectively. In this study, the best range for growth of Amygdalus scoparia species, NorthEast, elevation 1050-1250 meter and slope of 0-60 percent were identified. So, Topographical factors were one of the limiting factors of the growth, presence, and absence of Amygdalus scoparia species
