Phanersphyte
Study of floristic diversity of Labpur and surrounding other two blocks
Bolpur-Shantiniketan and Sainthia was carried out in 13 selected study sites
having uniform composition. A total number of 438 species of angiosperms were
encountered during the sampling of vegetation. Showing the diversity of flora.
They belonges to 87 families including 78 of dicotyledons and 09 of monocotyledons.
Based on species contributions. Papilionaceae (30), Cyperaceae
(30),Poaceae (25),Asteraceae (24),Solanaceae (20) were found as dominant
families. The phanersphytic and chamaepphytic life form was comparatively
higher in these areas. All specimens are preserved in herbaria of Botany
department of Sambhu Nath College, Labpur.

Species and diversity of tree species were analysed in 10 respresentative
forest sites occurring in Sagar District (Madhya Pradesh). 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.
