Composition, Structure of Mangroves in Gamui Estuary, Chudamani, Orissa, India

Authors: G. M. Narasimha Rao, P. Prayaga Murty

Mangroves and halophytic vegetation of Chudamani region and Dhamara mouth region of Gamui estuary, Orissa was studied by using the transect with 4x4m quadrate. In each station, 5 transect samples were collected and total samples analyzed for getting relative density, relative dominance and relative frequency of individual species in the studied area. Maximum Important Value Index (IVI) was obtained for the species Suaeda maritima and minimum value for Sonneratia apetala. A total of 11 plant species were reported, out of them 3 were true mangroves species, remaining 8 were halophytes. Along with data on plant populations hydrographical and sediment analysis was gathered to correlate with distribution and abundance of mangrove species. Maximum density was reported Suaeda maritima and minimum density for Prosophis juliflora. Maximum height of forest is only 2 to M 2.5 meters with diameter of plant species is not more than 26cm. Sediment analysis and low input of fresh water may be responsible for degraded mangroves with stunted growth.
