Abstract
ABSTRACT
The present investigation entitled “Studies on Woody Species Diversity in Bhaba
Valley of Himachal Pradesh” was carried out in Bhaba valley of Kinnaur district in Himchal
Pradesh to study the diversity and phytosociological studies of woody species. The complete
study area was divided into three altitudinal zones viz., lower (1500 -2500 m), middle (2500-
3500 m) and top zone (3500-4500m). Three sites were taken from each zone and in each site
three quadrates were further laid on the basis of species area curve for measuring species
diversity and phytosociological parameters. A total of 73 woody species were recorded of
which 31 were trees and 42 were shrubs. The maximum species 56 were recorded in lower
zone with 23 tree species and 33 shrub species followed by 36 species in middle zone with
12 tree species and 24 shrub species whereas minimum species 18 were recorded in top zone
with 8 tree species and 10 shrub species, respectively. In the present study, it was observed
that in total there were 73 woody species belonging to 48 genera and 27 families out of which
31 were tree species and 42 shrub species characterizing moist alpine shrub vegetation in the
study area. It was further observed that Pinus wallichiana and Prunus cornuta were present
in the entire valley area showing wide adaptability of these two species. The present study
revealed that the dominant, co-dominant and associated species were Prunus cornuta, Betula
utilis and Rhododendron companulatum in site Taudor; Betula utilis, Rhododendron
companulatum and Sorbus microphyla in site Nigul; Abies spectablis, Betula utilis and Acer
caesium in site Goldas; Acer caesium, Berberis lycium and Abies pindrow in site Muling;
Abies spectabilis, Acer caesium and Betula utilis in site Anyar; Pinus wallichiana, Picea
smithiana and Corylus jacquemontii in site Homti; Picea smithiana, Corylus colurna and
Pinus wallichiana in site Kangarang; Abies pindrow, Pinus wallichiana and Picea smithiana
in site Kafnu; Cedrus deodara, Pinus wallichiana and Pinus roxburghii in site Bai,
respectively.
