Abstract

Species composition and diversity of tree species were analysed in 10 respresentative forest sites occurring in Sagar District (Madhya Pradesh). As per values of IVI (Importance Value Index) six forest communities were identified. In general the forest vegetation of the district is either teak ( Tectona grandis ) dominating or teak associated. Species richness and species richness index ranged from 18 to 50 and 1.120 to 2.343 respectively. Shannon-Wiener diversity index ranged between 2.22-3.66 and Beta diversity ranged between 0.69-1.83. The values of concentration of dominance were generally low at all study sites indicating the dominance is shared by more than one and/or many species. Dominance-diversity curves showed log-normal distribution, also indicative of shared resources pattern by a number of species and mixed nature of vegetation.
