Impact of Weed Managements and Anthropogenic Stress on Quantitative Attributes of Plant Community Composition in Gopegarh Ecopark, Paschim Medinipur, West Bengal, India

Eco-parks are generally set up worldwide for serving both recreational and conservation purposes of local biodiversity through limited maintenance. Gopegarh Eco Park was set by the Forest Department, Government of West Bengal in highlands bank of Kangsabati  Kansai) river with a heritage ‘Garh’ area with remnants of Khan Raja’s establishment in Midnapore, West Bengal. This park was a place to study for its rich resources of indigenous vegetation, insects and birds for students and researchers. Increased development for amusements including picnic shades and human accessibility, intense weeding and mud ovens are set up. This study to measure quantitative characteristics of plant communities by quardrat method in low, moderate and severely disturbed zones revealed gradual decrease in indigenous flora with time; specially, herbaceous vegetation. The vegetation is gradually turning towards a monodominant tree community of Acacia auriculiformis, in low and moderate disturbed sites and Anacardium occidentale in severely disturbed sites; both planted earlier. Species frequency, diversity and density are decreasing with stress. The frequent cutting and weeding is affecting intensely on the ecosystem; decreasing soil moisture, organic carbon and changes in pH. This practice may affect propagule formation, dispersal and establishment of herbs, shrub and tree species. The park may gradually lose the indigenous flora and the flora dependant fauna and its utility as in situ sustainable maintenance of biodiversity and a resource place for practical study by students and researchers.
