A research team from the Manado Forestry Research Institute tested propagation methods for three coastal plant species at the Kima Atas Permanent Nursery in Manado, North Sulawesi. The three species are ketapang (Terminalia catappa), keben (Barringtonia asiatica) and nyamplung (Calophyllum inophyllum). This research is important because North Sulawesi is estimated to require 9,870,093.33 coastal plant seedlings to rehabilitate 14,805.14 hectares of damaged coastal ecosystem, with the largest portion, 13,884 hectares, located in other use areas.

The results showed that the three species require different treatments. Ketapang grows well under fluctuating temperature and humidity when sown in sand media, without wildlings, and placed under 25 per cent shade and exposed to rain. Keben can achieve up to 90 per cent survival within two months if its seeds are scarified and left to rot, then placed in an open location. Meanwhile, nyamplung requires treatment of its seed shell, either by cracking or peeling it, to increase its survival rate.

For communities living around forests and coasts, these findings provide practical guidance for propagating their own seedlings to replant damaged coastal areas. The research notes that seedling demand in North Sulawesi is very high, so appropriate propagation methods are crucial to the success of coastal rehabilitation.
