Introduction:The study was conducted in Mudumalai Tiger Reserve,in the Western Ghats to understand the effect of a single fire event on tree diversity and regeneration *** forest patches were selected which were unburned,2-year-old burn,5-year-old burn,and 15-year-old *** 0.1 ha square plots were laid randomly in all four patches and analyzed for tree diversity,stand structure,and regeneration of tree ***:A total of 4129 individuals of tree species were recorded in field surveys,comprising 3474 seedlings,121 saplings,and 534 ***,40 tree species were recorded in study plots,from which 28 species were seedlings,16 species were saplings,and 37 species were at tree ***:Tree diversity decreased in 2-year-old and 5-year-old burnt plots and was reached to the level of unburnt plots in 15 years of *** of small size classes started increasing after the *** density increased linearly in subsequent years after fire but sapling and tree density recorded less than control in B2 but was higher in B5 and *** overall fire affected diversity,but regeneration showed a positive trend.

Anthropogenic disturbances and status of forest and wildlife in the dry deciduous forests of Chhattisgarh state in India

Journal of forestry Research 2012年第1期23卷 45-52页

The advent of modem forces and the changes in socio- economic patterns of forest dwellers have increased the pressures on the forests. In order to mitigate such pressures and also to protect the forests and wildlife the model of protected areas networks has shifted and en- hanced such pressures in the unprotected natural forests due to several reasons. Being a low profile category of protected status and continuous human settlements, the present study highlights the case of dry deciduous forests of Sarguja district of Chhattisgarh state of India. The major objec- tives of this study were to quantify the status of forests and wildlife and also to determine the extent of anthropogenic disturbances faced by the dry deciduous forests of central India. Transect and silent drive count methods were used for sampling wildlife and quadrat method was used for sampling vegetation. Besides, the local uses of various forest pro- duces were also studied in view of understanding the people dependency on forests. The forest vegetation, in the study area, was pre-dominated by Shorea robusta, which had Madhuca indica, Diospyrus melanoxylon and Buchnania lanzan as the major companion species. The forest had either the high girth class mature tree species or the saplings. The low vegeta- tion cover and density were due to the high anthropogenic pressures mainly in the form of heavy livestock grazing and collection of etlmo- botanically important species. The study though reveals that the area is not rich in wildlife and the forest is fragmented, the area still supports some important species, which include many rare and endangered plants and animals. The findings of this study have been discussed in view of the management and conservation of the forest and wildlife in the dry deciduous forests.
