Abstract
ABSTRACT
The present investigation entitled “Floristic composition and rate of carbon sequestration
potential of plantation forest ecosystem mid-hills of Himachal Pradesh” were carried out at the
different sites in and nearby vicinity of Dr. Y.S. Parmar University of Horticulture and Forestry,
Nauni, Solan located at 30° 50’ 30” to 30° 52’ 0” N latitude and the longitude 77° 8’ 30” and 77° 11’
30” E in Himachal Pradesh lying at an elevation of about 900-1300 a.m.s.l. The area falls under
Champion and Seth’s forest type 9C1- Lower Himalayan Chir Pine Forests. For conducting the
experiment under plantation ecosystem, different plantation were selected as treatments, which
included; Quercus leucotrichophora, Pinus roxburghii, Acacia catechu, Acacia mollisima, Albizia
procera, Alnus nitida, Eucalyptus tereticornis and Ulmus villosa plantation. Biomass allocated by
different vegetation type was estimated by using non-distructive method of sampling. The result of
experiment reveals that Lantana camara was the dominating shrubs species while Bidens pilosa was
the dominant herb in almost all the plantation forest ecosystem. Moreover, the Acacia catechu had the
highest positive impact on the soil physico-chemical properties. The maximum biomass (305.43 Mg
ha-1) recorded in Ulmus villosa. Vegetation carbon density in plantation forest ecosystem followed
the order; Ulmus villosa> Albizia procera> Eucalyptus tereticornis> Quercus leucotrichophora>
Alnus nitida > Pinus roxburghii> Acacia mollisima>Acacia catechu. Rate of carbon sequestration
and carbon mitigation follow the similar trend: Ulmus villosa> Albizia procera> Quercus
leucotrichophora> Alnus nitida > Acacia mollisima> Pinus roxburghii> Acacia catechu >Eucalyptus
tereticornis.
