Species diversity under different management systems- a case study in Amlachati Range of Midnapore West Forest Division

摘要

In the present communication, the impact of different management systems on biodiversity conservation in Amlachati ofWest Midnapore Forest Division has been assessed.Vegetation survey of plant communities and distribution pattern were conducted through Important Value Index (IVI) in three types of forest communities, such as FPC managed forest, plantation stand managed by State Forest Department and degraded forest. The survey covered four major seasons viz. summer, monsoon, post monsoon and winter in this region.The highest number of species was found during post monsoon in all the communities and lowest during pre-monsoon period. Comparing different phytosociological parameters, FPC managed forests were found to have more diversity in species structure irrespective of seasonal variations.The study indicates that involvement of forest fringe people in protecting the forest through JFM can increase the forest cover. The results also indicate that the nutrient status was higher in FPC managed forestsoil than that of the other two sites.
