摘要：There is an imperative interrelationship between people and forests however forests loss is continued which causes several complexities. This research was objectively done to show the effects of carbon stock on species ranking in collaborative forests (CFMs). The randomized block design (RBD) was set and stratified random sampling was applied to collect the biophysical data. Total 33, 32 and 31 samples were collected from Banke- Maraha, Tuteshwarnath and Gadhanta- Bardibash CFMs respectively; establishing 20*25m2 plot for trees using GPS coordinates. The height and diameter of plants were measured. Additionally, frequency and density of plant species were also recorded. Latter biomass was calculated using equation by Chave et al. and importance value index (IVI) was also calculated to prioritize the species. Additionally, mix rank was also estimated by using IVI and carbon to evaluate effects of carbon on species ranking. It showed that, estimated highest IVI was 68.59 in Shorea robusta in Tuteshwarnath CFM. The carbon stock of Shorea robusta was the highest 50.43±0.43 t ha-1 in Gadhanta- Bardibash CFM. Total 11 species like Dalbergia latifolia, Schleichera trijuga, Croton roxburghii and Acacia catechu were promoted their rank under mix criteria. This showed that there was effect of carbon on species ranking.
