Abstract


The present study encloses the analyzement of vegetation type, its richness and studies of surface and sub-surface soil samples of two active and two presently passive landslide prone areas of Sikkim. The identification of dominant, origin and effective plant species is done in each four landslide areas. The process will be helpful in studying the mitigate measures in controlling the soil erosion in hill region. The study on Physico-chemical parameters of soils of these four landslide areas has shown, more acidic the soil, active the landslide in the region. The categorized two active landslides Beto and Namli along with one passive landslide of Ganeshtok were confined of high acidic value. The vegetation cover of these landslide area is highly been effected by its ill-nutrient contentment. The dominance of particular plant Biodiversity is not always supportive for managing the chemical nutrient like N2. The study emphasizes on these by studying the pattern of vegetation cover. All the landslide prone areas were confined mainly of Nitrogen fixing plant species like Alnus. The diverse species with dense vegetation is examined to be more efficient. High slopes are not only the reason of Landslide eruptions but other soil parameters factors also held such eruption The study has endowed to new beginning clarifying the culturing of preferable and landslide mitigating efficient plant species in landslide areas of Himalayas.
