Abstract


Ecosystem a geographical area where biotic and abioticlive together and make a bubble of life. Riparian riverinevegetation in restoring the stability of slopes becomeshighly demanded specially to solve the problem of soil oferosion, shallow slope failure in both natural and man-made slopes. Planting or preserving vegetation in areasvulnerable to erosion is therefore considered to be a veryeffective soil erosion control measure. Plants roots may stillbe present underground and play an important role inprotecting the topsoil from being eroded. The load requiredto remove the root system of selected plant speciesvertically from the soil was used as a measure of soilbinding capacity. We have observed maximum and
minimum uprooting. We found highest "soil binding factor.Selected plant species will have maximum soil binding
capacity. The additional shear strength imposed by thegrass roots was observed maximum for tree species andminimum was observed for grasses species. Root systemslead to an increase in soil strength through an increase incohesion brought about by their binding action in thefibre/soil composite. From this study, it has proven thatgrasses, shrubs and tree species are effective for erosioncontrol, providing a complete ground cover and grass rootshave a mechanical effect in increasing soil strength. Thesoil tensile values are used to rank species according totheir potential to reinforce the soil The frameworkpresented highlights that the importance of riverine habitatsmay be quite variable in species having directional
dispersal networks across the fluvial landscape inmountainous areas of India. Results from this frameworkcan serve as the basis to apply a mechanisticunderstanding to managing and protecting native populationsthrough regional restoration actions. A very high species diversityof tree species with individuals were recorded within the of areasampled. Among major species, Albizia lebbeck, Ziziphus, Beutiamonosperma, mauritiana, Bambusa arundinacea,  Dalbergialanceolaria,Wrightia tinctoria, Tamarindus indica, Tectonagrandis, Pongami apinnata, Ailanthus excelsa and Syzygiumcumini were the predominant tree species estimated top tenranking order of Important Value Index (IVI). Fabaceae,Moraceae, Euphoraceae, Anacardiaceae, Meliaceae,Mimosaceae and Rubiaceae were the seven dominant familiesreported maximum species richness ranged from eight to fourspecies. and dominance of a species, selected species of top 20ranked IVI value were recommended for restoring the riverine ecosystem.
