Habitat fragmentation due to development from 1989 to 2013 left around 767 individuals in two wild populations, which are predicted to be unable to survive for the next 500 years. This research aims to analyze community perceptions and participation in the initiation of the Tapanuli Orangutan Corridor development in Hutaimbaru. The research method used was a quantitative approach with a sample of 30 respondents. The results showed that the community’s perception level of corridor development was in the moderate category with a percentage of 61%, while the level of community participation was in the high category with a percentage of 67%. This condition indicates that although community understanding of the corridor program is still limited, they respond positively and demonstrate active involvement. This research emphasizes the importance of a participatory approach through community-based agroforestry development as a corridor-building strategy, which not only benefits the conservation of the Tapanuli orangutan but also supports the improvement of local community welfare.</p> Dede Syahputra Tanjung T.
