Diversity, utilization, and sustainable management of Baccaurea spp. in agroforestry systems of West Sulawesi, Indonesia
摘要
Species of the genus Baccaurea—underutilized fruit trees native to Southeast Asia—offer considerable potential for both biodiversity conservation and rural livelihoods. Despite their presence in traditional land-use systems, their ecological roles, utilization patterns, and sustainable management within multifunctional landscapes in West Sulawesi remain poorly understood. This study aimed to: (1) document the diversity of Baccaurea species; (2) evaluate their ecological and ethnobotanical significance; and (3) identify key challenges and opportunities for their sustainable cultivation. Field surveys and ethnobotanical interviews were conducted across home gardens, mixed-tree agroforestry, and forest-based systems in the Mamasa and Mamuju Regencies. Three species were identified: Baccaurea lanceolata, B. costulata, and B. racemosa. Among them, B. lanceolata had the highest Relative Frequency of Citation (RFC = 0.78) and was widely used to treat coughs and skin ailments. While 42% of respondents cited commercial potential as a motivation for cultivation, 27% emphasized medicinal uses. However, barriers such as limited market access and scarcity of planting material were pervasive. Notably, no significant correlation was found between cultivation interest and perceived constraints (p = 0.2), indicating systemic barriers. The findings highlight the need for integrated conservation strategies, phytochemical validation, and improved value chains to promote Baccaurea as a culturally and ecologically valuable component of sustainable agroforestry development in Indonesia.
