Lack ofnon-forestry incomesources for the forest-dependent community was oneof the major causes of continued biodiversity loss in Chunati Wildlife Sanctuary (CWS). A livelihood support program was implemented from July 2012 through June 2015 to reduce people’s forest-dependence for their livelihoods. We evaluated the efficacy of this program in enhancing the biodiversity health of CWS. An Ordinary Least Square regression framework was used to estimate the difference in difference of the income between the control and the treatment households. Alongside, the biodiversity attributes of the CWS were measured in 2012 and 2015 and were compared. The intervention increased a treatment household’s monthly non-forestry income by BDT11,781 and decreased its monthly forest income by BDT2128. In contrast, with increased natural regeneration of 8.43%, 12 out of the 16 major species at CWS showed increased importance value index (IVI). The IVI increased by 48.03% for Acacia auriculiformis and decreased by 56.30% and 31.76% for Dipterocarpus turbinatus and Tectona grandis, respectively. As confirmed by the households, this biodiversity improvement could be attributed to the livelihood intervention program at CWS. Continued monitoring is important to sustain the successes of the program.
