Abstract

Change in ecosystem balance is increasing rapidly by means of humanly devised over and above natural activities to be precise land use change, deforestation, species invasion, and even the lack of sustainable management within and beyond protected area. Invasion of woody perennials and invasive alien species, human intervention together with improper management practices possibly generated substantial impacts on all major ecosystems of Shuklaphanta grassland. To acquire baseline information and understand ecosystem invasion, random line transects of 1000m were taken to get quadrats of 1m2, 25 m2 and 100 m2 in four different habitats within Shuklaphanta grassland. The result showed that the importance value index (IVI) and prominence value (PV) of woody perennials were high coupled with significant PV of invasive species. Ecosystem services change was prevalent in the study area and high possibility to change into forest vegetation. Invasive species, shrubs, and large trees encroachment consequently invited alteration challenge on preferable habitats formed on assemblage of major grass species. The disrupted ecosystem services amplified pressure on both prey and prey base species including swamp deer, antelope, one-horned rhinoceros, Asiatic elephant, royal Bengal tiger, Bengal florican and other threatened species.
