The assessment of carbon storage potential has been difficult due to the lack of information on biomass compartmentation and carbon allocation in different species. For most of the species used for afforestation/reforestation, only the above ground biomass potentials are known but to have a picture of carbon storage potential species, the below ground biomass pattern are equally important.

An evaluation was made on the performance of three tree species viz. Alnus nepalenis D. Don. Melia azadirachta A. Juss. and Gmelina arborea Roxb. and their interactive effects on crop yield during establishment period. The seedlings of all tree species survived better under cropped than un-cropped plots.

Agroforestry has high potential for simultaneously satisfying three important objectives viz., protecting and stabilizing the ecosystems; producing a high level of output of economic goods; and improving income and basic materials to rural population. Besides, agroforestry is capable to conserve natural resources through various systems under different agroclimatic regions.
