Abstract

The Royal Bardia National Park (RBNP) of Nepal has 35% land as riverine forest.Vegetation composition and biomass production in Evergreen Riverine Forest (ERF), and Deciduous Riverine Forest (DFW) of the RBNP were studied by lying quadrats of 25 m x 25 m. The ERF was mainly dominated by Syzygium cumini, MalIotus philippensis, Ficus racemosa, Bombax ceiba and Adina  cordifolia, whereas, DRF was dominated by A. catechu and Dalbergia sissoo. Syzygium cumini possessed higher density and basal area in ERE; whereas Acacia catechu had higher density and basal area in DRF. Density diameter distribution curves of stems showed that most of the stems were between 10-25 cm in diameter. The aboveground biomass was 459.74 t hi-1 in ERF and 150.65 t ha-1 in DRF.
