Data and informations on ramin seed sources are very important to develop ramin plantation. Data and informations were collected in two provinces, West Kalimantan and Central Kalimantan. This report contains result of exploration of ramin seed sources in these two provinces. Several institutions were visited such as Forest Research Institution, Provincial and District Forest Service, University, NGO and Sebagau National Park. Additional data and informations were also collected through literature search. Several findings are summerized below:
1. Ramin population is widely distributed in West and Central Kalimantan. However, the existing population is seriously under threat due to over exploitation. Moreover, most of the existing natural distribution are located in non secure forest area or in what the so called “convertible forest land for other uses” (Areal hutan untuk Penggunaan Lain-APL). Therefore, it is recommended that the suitable site for seed sources of ramin should be immediately bordered and designated.
2. The Air Be(r)guruh in Tanjung Pura village, District of Ketapang is the most suitable and potential site for ramin seed source. Population density is high with abundant of seedlings and saplings. This site could be source of vegetative materials for vegetative propagation. It is recommended that this site is immediately designated for seed source of ramin in West Kalimantan.
3. In Central Kalimantan, the certified seed source of ramin is in Lahei, Kecamatan Mentangai, District of Kapuas. This site is the best seed source for ramin in Central Kalimantan. In order to secure this site, it is recommended that maintenance and protection from other potential disturbance be intensified.
4. The support from local stakeholders to conserve ramin habitat and plantation activity should be considered as an opportunity to promote rehabilitation and conservation of ramin. Local government should be actively participated in the management of peat swamp forest, as sources of timber and the sources of biodiversity by maintaining the peat swamp forest from conversion to other uses.
It is expected the above findings are useful in order to promote the success of ramin plantation and rehabilitation.
