SudhakarPattanaikChiranjibi BrahmamM. 2200712Phytosociological study was carried out in tropical dry deciduous forest of Boudh district, Eastern Ghats of Orissa, India. We inventoried a total of 187 species (trees 91, shrubs 10, climbers 12 and herbs 74) with in a four hectare sampled area. The predominant tree species are Shorea robusta, Madhuca indica, Buchanania lanzan, Cleistanthus collinus and Diospyros melanoxylon. Study area shows species rarity (those represented by ≤2 individuals) of 18%. The Shannon-Weiner index (H') is 4.51, with Simpsons value 0.92 infer that tropical dry deciduous forests are also species diverse systems. Mean stand density was 591 ha-1 and mean basal area was 25.50 m2 ha-1. Stand density and species richness have consistently decreased with increasing girth class of tree species. Girth class having <30 cm gbh contributed to about 68.13% of species richness. The present study can serve as baseline information for monitoring and sustaining the phytodiversity of tropical dry deciduous forests in the State of Orissa.]]>Abdulhadi, R., E. Mirmanto and K.A.
