Abstract

The present study was undertaken to understand the community behaviour of Nardostachys jatamansi in three different sub sites viz., maximum, moderate and minimum density levels in the alpine areas of Kedarnath region of Rudraprayag district in Uttarakhand. The results reveal that the density was highest in the maximum sub site followed by in the moderate and minimum sub sites. Analysis of vegetation revealed that between different densities the community composition did not vary much. Although between various sub sites the density varied significantly between maximum, moderate and minimum categories, comparison of mean density of the area.  Maximum density was represented by a total of fifteen plant species, while moderate and minimum densities showed twelve and thirteen plant species respectively.
