Abstract
Twenty-two stands in gadap area
southern sind were sampled quantitatively and soil samples were analysed physically and chemically . the leading dominant technique revealed the ecological affinities among the dominant species. Diversity analysis of leading dominant groups showed minimum diversity for cordia gharaf group and maximum for euphorbia caducifolia group. Species richness was mainly rresponsible for changes in general diversity whereas the equitability component was insignificant. Cover per acre (standing crop) and density per acre of perenntal species were found to be inversely related to diversity measures. Objective classification of vegetation disclosed three community types . community type l, confined to sandy plains, is dominated by pteropyrum olivieri, cordia gharaf and capparis decidua , and appears to be correlated with soils having moderate depth,
