Abstract

The work reported in the thesis with the title, CONTRIBUTION TO THE FLORISTICS AND PHYTOSOCIOLOGY OF BANNI REGION, KACHCHH DISTRICT, GUJARAT - INDIA has been described as under. newlineIt is very imperative to know the floristic and Phytosociology of an area mainly to know the Structure and composition of plant community. It is an important aspect of ecological estimation of vegetation dynamics which reveals the structural arrangement of various components in plant community and helps to understand the community structure and diversity. The present investigation was carried out the floristic enumeration and composition of vegetation in the Banni Region (BR) of Kachchh district, Gujarat. Through, the present ecological and ethnobotanical study in the Banni areas (2011-13), able to list a total 219 plant species. In which, 165 species were dicots and the remaning (54) were monocots. All the species belonged to 51 families and 158 genera. Poaceae was the most dominant family represented by 45 species followed by Asteraceae, Amaranthaceae, Cucurbitaceae and Euphorbiaceae. Cyperus and Eragrostic were the dominat genera of Banni region and Indigofera, Ipomoea, Sporobulus, Cassia, Cenchrus, Convolvuulus, Corchorus, Euphorbia, Ficus and Solanum are also dominant genera of the Banni region. Among the total number of plant species 175 were common, 31 not common, 4 not frequent and 9 species were recorded as a locally rare. newlineIn addition, out of the total recorded 19 threatened plants of Kachchh, only two were reported from the Banni regions which are Ammannia desertorum Blatt. and Hall. and Citrullus colocynthis (L.) Soland. During the intensive floristic inventory, a total of 12 species were reported as new to Banni region, which are Elyonurus royleanus, Manisurus granularis, Anisomeles indica, Ipomoea nil, Merremia gangetica, Psoralea plicata, Rivea hypocrateriformis, Setaria verticillata, Typha angustata, Zornia gibbosa, Salvadora persica Var. indica and Convolvulus auricomus.
