Propagation of Mangifera casturi using conventional and tissue culture techniques
The Indonesian Society for Ethnobiology (Perhimpunan Masyarakat Etnobiologi Indonesia - PMEI) has officially launched an innovative conservation project focused on propagating saplings of Mangifera casturi (Kasturi mango), an endemic species of South Kalimantan listed as Extinct in the Wild on the IUCN Red List. This project aims to propagate Kasturi saplings using a combination of two methods: conventional propagation techniques and laboratory-based tissue culture techniques.
This initiative is led by Range Harnata Palodang as Project Coordinator and receives full support from The Mohammed bin Zayed Species Conservation Fund (MBZ Fund), an international philanthropic institution committed to supporting efforts to save endangered species worldwide. Activities are centered in Banjar Regency, South Kalimantan Province, the native region of Mangifera casturi.
The Kasturi mango is an integral part of the ecological and cultural identity of South Kalimantan. Unfortunately, its existence in its native habitat has been lost due to forest degradation and landscape changes. Through this project, we aim to bring this crucial species back to the forests of Kalimantan by ensuring an adequate supply of healthy saplings.
From Propagation to Reintroduction

The Kasturi saplings produced by this project will be the primary source for reintroduction activities into their natural habitat in the Kalimantan forests. Reintroduction is planned for the early rainy season, around October 2025, to give the saplings a greater chance of survival thanks to ample water availability and favourable climate conditions.

Through this science-based approach, PMEI hopes the reintroduction process can serve as a strong initial step in rebuilding the wild population of Mangifera casturi. In addition to planting saplings, the activities will include monitoring plant growth in the field to ensure success rates and to gather vital data for long-term conservation research.
About Mangifera casturi
Mangifera casturi fruit
Mangifera casturi, more commonly known as Kasturi mango, is characterized by its fragrant aroma, dark orange flesh, and unique sweet flavour. This fruit holds significant economic and cultural value for the people of South Kalimantan, often regarded as a symbol of provincial identity.
However, pressures from deforestation, land conversion, and logging have led to the loss of the species' natural habitat. As a result, the Kasturi mango is now only found in community gardens, conservation collections, and botanical gardens, and no longer grows naturally in the wild. This situation has led to Mangifera casturi being classified as Extinct in the Wild on the IUCN Red List.
