Description A Thesis titled “Vegetation composition, structure and biomass estimation of selected forest areas in Chamoli district of Garhwal Himalayas” was submitted in partial fulfillment of the requirement for the award of the degree of Doctor of Philosophy in Forestry by Vijaya Rawat.
The study entitled “Vegetative composition, structure and biomass estimation of selected forest
areas in Chamoli district of Garhwal Himalaya” was conducted at Chamoli district of Garhwal
Himalaya during 2012.The study was carried out in eight different forest of Chamoli District at
the height elevation of 1000 – 3000m amsl with northern and southern aspects of each
elevation.The study was conducted to find out the phytosociological structure and biomass
estimation of these forests.
The IVI was recorded maximum in tree species in F1- forest Boehmeria rugulosa, in F2-forest
Bombax ceiba, in F3-forest Cedrus deodara, in F4 – forest Lyonia ovalifolia, in F5 – forest
Machilus odoratissima, in F6- forest Ficus palmata, in F7- forest Quercus leucotrichophora and
in F8 –forest Acer oblongum. The dominance index (Simpson index) of tree species was highest
in forest - F5 (0.794). The value of (SD) in tree species was highest in Forest – F5 (1.622). The
value of tree species equitability was highest in forest – F5 (0.124). Tree species richness was
recorded maximum in forest – F2 (0.109) Beta diversity was recorded maximum in forest – F7
(10.300).
The standing volume of eight forest sites were taken and the maximum standing volume was
recorded in forest F3 (198.260 m3/ha) followed by forest F4 (186.290 m3/ha) at elevation of 1500-
2000m amsl. Similarly the least volume was found in forest F2 (134.490m3/ha) followed by
forest F1 (150.120m3/ha) at elevation of 1000-1500m amsl.
The socio economic status of eight villages with a total of 521 households surveyed during the
study, including 2820 members in different groups and community. The average family size was
reported to be 5.41 members per family. During the survey of villages, it was found that the adult
literacy rate in male was 51.19% as compared to female literacy rate 48.80% respectively. In
livestock status of the eight villages the various categories of livestock the buffaloes were the
maximum 57.82% followed by sheep/goat 26.30%.
The average daily fuel wood consumption pattern during summer and winter in different
villages varied from 83.41 kg/day/village to 535.40 kg/day/village in summer and 150.70
kg/day/village to 757.05 kg/day/village in winter which are supplemented by existing
agroforestry up to considerable extent. The utilization of tree fodder varied from 301.05
kg/day/village to 1009.15 kg/day/village in the summer and 650.50 kg/day/village to 2011.50
kg/day/village in the winter season which is also supplemented by traditional agroforestry trees
in a sizeable limit. The land holding size ranged from 0.03 to 5.6 ha per family with 77.9 %
families under marginal category, 19.05 % under small category and -3.04 % families
comparised of medium- large landholding size.
