Abstract

The Tapanuli orangutan (Pongo tapanuliensis) is critically endangered and inhabits the Batangtoru Ecosystem, the last refuge of the southernmost orangutan population in Sumatra. 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.

Abstract

The Tapanuli orangutan (Pongo tapanuliensis), currently classified as critically endangered, inhabits the Batang Toru Ecosystem and persists in two wild populations. This study aims to analyze habitat suitability for the Tapanuli orangutan, the Importance Value Index (IVI), the Shannon Diversity Index (H′), and the Margalef Species Richness Index (Dmg) of tree species. Model accuracy, assessed by the Area Under the Curve (AUC) of a random test based on 25% of samples, was 0.993, while the overall predictive AUC reached 0.996, both classified as “excellent.” Elevation, precipitation, and distance from forest cover emerged as the most influential environmental variables. Habitat suitability classification revealed 60.23% as “unsuitable,” 28.77% as “suitable,” and 11.00% as “highly suitable.” In secondary forest, the highest IVI values were observed for hoteng (Lithocarpus hystrix) at 28.68%, mayang (Palaquium gutta) at 22.55%, and hayu horsik (Ilex pleiobrachiata) at 17.81%. In mixed gardens/agroforestry systems, durian (Durio zibethinus) had an IVI of 21.44%, mayang (Palaquium gutta) 18.82%, and medang (Persea declinata) 18.48%. Shannon diversity (H′) was high in both secondary forest (3.19) and mixed gardens/agroforestry (3.23), while stem density diversity was moderate in secondary forest (2.71) and mixed gardens/agroforestry (2.53). Margalef richness (Dmg) was high in both secondary forest (5.63) and mixed gardens/agroforestry (5.96), whereas stem richness was high in secondary forest (4.51) but moderate in mixed gardens/agroforestry (3.79).
