ECOLOGICAL SIGNIFICANCE OF FORESTS AND ECONOMIC DEPENDENCE ON IT IN THE NARMADA FOREST DIVISION OF SURAT FOREST CIRCLE OF GUJARAT, INDIA
Abstract
The present research is comprised of seven chapters ie. Introduction, Literature review, Study area, Materials and Methods, Data analysis, Results and Discussions and Conclusions, This study was done for knowing the ecological and economic significance of the Narmada Forest Division (NFD). Forest is the significance for surviving living organisms because it provides all benefits free of cost forest provides all kind of ecosystem services like Carbon sequestration, Soil conservation, Purification of water, Maintain local climate and Biodiversity support etc. The most valuable product from the forest is wood, which has a huge diversity of applications and purposes, such as building purpose, furniture, Fuel wood purpose, NTFPs (Non Timber Forest Products), Medicinal plants etc. Total carbon sequestration and biodiversity support in the division was studied by using available literatures. Total 90 soil samples were taken from various forest type, density classes and topography. Status of following parameters viz. Soil Organic Carbon (SOC), Total Nitrogen (TN), Carbon Nitrogen ratio and pH in the forest division was found out by using proper methods. For present study primary and secondary data collection process was done. Households’ survey was done to find out the ethnobotanical uses of plants, the total economic value of forest resources and dependence on it. Further, all collected data was analyzed using simple statistics. NFD supports about 668 angiosperms including 145 native trees species belongs to 44 families, 76 species of climbers of 15 families, 324 varieties of herbs belongs to the 65 families, 56 species of shrubs belonging 27 to families, 67 kinds of grass of poaceae. Total estimated biomass of the NFD is 1719616.0 Metric tons per annum which has the potentiality of total of 113854.8 Metric tons of carbon per annum. Narmada Forest division has feasible for groundwater extraction. The soil of NFD was slightly acidic to neutral in DDF and MDF while RF soil is slightly acidic to basic in nature. First layer of soil showed high Soil Organic Carbon and Total Nitrogen. C/N ratio is in the range of good forest soil. A total 38.7 % population of the total population of the district is depending on forests for their livelihood. Total Economic value in NFD is 26.76 Cr. INR from various sectors i.e. Fuel wood (14.55 Cr.INR), NTFPs (7.7 Cr.INR), Fodder (3.6 Cr.INR) and Timber (0.91 Cr.INR) in Narmada Forest Division. Total 20 plant species of 15 families, belonging to 20 genera were recorded in NFD which is used as ethnobotanical and medicinal purposes.
