Exclusion and not using of rangeland in the long term affects the composition and homogeneity of vegetation and consequently leads to the improvement of plants status. In this study, the characteristics and structural changes of the rangeland of Gonbad, Hamadan province, Iran, in 2014 (after 20 years of enclosure) were evaluated using Braun-Blanquet plot, Phytosociology and multivariate analysi...

Abstract Context Land-cover class definitions are scale-dependent. Up-scaling categorical data must account for that dependence, but most decision rules aggregating do not produce scale-specific definitions. However, non-hierarchical, empirically derived classification systems common in phytosociology define classes using species co-occurrence patterns. Objectives Evaluate tradeoffs precision a...
