The present study assessed the vegetation dynamics and plant diversity along the stream bars during post-monsoon in the Kempty Watershed of Uttarakhand, India. A phytosociological survey of the riparian zones was conducted for trees, shrubs, and herb species. Vegetation sampling was done using the quadrat method and 20 quadrats of 10 x 10 m, 3 x 3 m and 1 x 1 m for trees, shrubs and herbs were laid in five different sites for studying vegetation composition and structure. Density (Ind/ha) and basal area were also calculated for each species. A total of 9 species of trees, 8 species of shrubs, and 20 species of herbs and grasses were encountered across and along the waterbody. The most common plant species among shrubs and herbs was Ilex dipyrena (IVI 16.7) and Oplismenus burmannii (IVI 27.7). Quercus leucotrichophora (IVI was 30.5) was the dominant tree species, followed by Daphniphyllum himalayense (IVI was 15.1) in the study area. Cluster analysis revealed the association between different plant species. Ilex dipyrena is a leading dominant shrub species along the stream of the study area. Thus, the study provides information to understand the current status, ecology, and spatial distribution of vegetation on stream bars and riparian zones and the potential habitat of different species for required conservation efforts.
