Sustainability in community forest (CF) is a very important issue but study regarding this is limited in Nepal. Thus, this research study was objectively conducted to assess the sustainability index including socioeconomic contribution and biodiversity status of tree species in Simpani, Bolde Setidevi, and Kalobhir community forests of Dolakha district. A total of 83 sample plots were established to collect the biophysical data. The sustainability index for overall and individual criteria was assessed on the basis of scoring provided by the community forest user groups (CFUGs). The study showed that there were 87% Braman and Chhetri in Simpani CF and their representation was 91% in the executive committee, and similar status was seen in Bolde Setidevi and Kalobhir CFs. The highest number of households were 29 receiving benefits from the timber in 2016/17. They used roughly 164.9 m3 wood from Kalobhir CF. The highest total income was US$1495 in 2016/17 in Simpani CF, but expenditure was the highest, US$1817 in 2017/18, in Bolde Setidevi CF. There was 6308 regeneration per ha in Simpani CF but growing stock was the highest, 177.7 m3/ha, in Bolde Setidevi CF. The Shannon Wiener index was the highest, 0.92 ± 0.087, in Bolde Setidevi CF. One-way ANOVA showed that there was no significant difference in values of the Shannon Wiener index and evenness index of the three community forests since p value is |
