Description |
In the present study an attempt has been made to investigate the ?Effect of Forest Fire on Microbial biomass, Storage and Sequestration of Carbon in a Tropical Deciduous Forest of Chhattisgarh? at Bhoramdeo Wildlife Sanctuary of Kawardha Forest Division in Kabirdham district during the year 2011?2013. The study was conducted in four fire regimes viz., High, Medium, Low and No fire zones of tropical deciduous forest. The variation in species structure, composition, diversity, biomass, C storage, litterfall, net primary productivity, C sequestration, C stock, soil characteristics and soil microbial biomass in all the fire regimes were quantified. The observations of the study in the different fire regimes at surrounding areas of Bhoramdeo Wildlife Sanctuary indicated that the agriculture is at subsistence level and tribal people?s dependency on these forest resources for the livelihood in all the respective sites. In all the fire regimes human settlement was mostly dependent more or less on similar types of resources. In these sites, fires are ignited intentionally from February to April to facilitate the collection of Tendu leaves and Mahua flowers and also for honey collection. The chief source of energy and one of the resources used in the entire site is fuelwood collection from the forest areas throughout the year. The animal grazing is another heavy pressure in the study areas. Collection of non-timber forest products (NTFPs) including leaf collection for making the plates (Dona), medicinal plants and other minor forest produce by the human population is the regular process in the area. These are the very important resource types recognized for their high economic value to the people. The present dry deciduous forest is characterized by poor species content. Non linear inverse relationship between density vs. girth showed small structure with only 1.58- 2.18% individuals occurring in girth class >50 cm. In the present forests a total of 380 trees ha-1 were encountered in high fire zone, 490 trees ha-1 in the medium fire zone, 610 trees ha-1 in low fire zone and 880 tree ha-1 in the no fire zone. The basal area of the tree species across the fire zone ranged from 11.13-33.54 m2 ha-1 lowest in high fire zone and highest under no fire zone, respectively. Among the fire regimes the no fire zone exhibited highest proportion of saplings and trees density, and seedlings after the low fire zone. The total biomass varied from 116.03 to 358.36 t ha-1 for tree, 6.82 to 15.71 t ha-1 for shrubs 0.37 to 0.88 t ha-1 for herb, 6.58 to19.16 t ha-1 for fine root and 2.00 to 3.65 t ha-1 for litter mass. The above ground biomass was 111.99- 323.37 t ha-1 and below ground was 23.68-65.17 t ha-1. The total carbon storage across the forest fire |
