Abstract
Carbon sequestration is one of the main ecosystem services in today’s condition. Estimation of above ground tree biomass and carbon stock is important as it gives ecological and economic benefits to the local people. This study was conducted in the Hasantar Community Forest (HCF) of Nagarjun Municipality, Kathmandu. Concentric circular plots of 12.62m radius were established in five different blocks of HCF for the study of tree species. The main objective of this study was to find out the Important Value Index (IVI), Above Ground Tree Biomass (AGTB) and carbon stocks tree species of HCF. This forest comprises the tree species of families like fagacaeae, moraceae, myrtaceae, fabaceae etc in dominant numbers. Schima wallichii was found ecologically most significant tree species as it possess highest IVI value. The carbon stock of this plant was found as 206.865 t/ha which comprises 27 % of total carbon in HCF. The total above ground tree carbon stock of HCF (55.4 ha.) was found 144.795 t/ha.

Highlights
Community forestry is a participatory forest management system in Nepal that was started in the late 1970s. Glimour and Fisher (1991) defined community forestry as the control, protection and management of forest resources by rural communities for whom trees and forests are an integral part of their farming system
According to Hasantar Community Forest User Group (HCFUG), this forest is in pole stage where maximum plants have diameter 10cm to 29.9 cm
Diameter at breast height (DBH) Class of the Trees The largest number of tree species in HCF was found in 2130 cm DBH class. 31% of total trees were found in the DBH class 21-30 cm and only 1% of the trees were in DBH class
Summary
Community forestry is a participatory forest management system in Nepal that was started in the late 1970s. Glimour and Fisher (1991) defined community forestry as the control, protection and management of forest resources by rural communities for whom trees and forests are an integral part of their farming system. According to Forest Act 1993, community forest is a part or parts of National forest area handed over to a user groups for its development, conservation and utilization for collective benefit of the community. It is an institutional innovation of empowering local communities in managing forest resources for their benefit in co-ordination with government. It was established in 2051 according to the Forest Act 2049. It lies about 3.5 Km north from Kalanki, Kathmandu.
