Dyera polyphylla, which is locally known as jelutung, is a tree that produces latex. The latex is used for chewing gums, insulator, tube, and others. The wood is soft and bright colour, which can be used for pulp, plywood, pencil, wooden toy, and others. It naturally grows on peat swamp forests in Sumatra and Kalimantan (Indonesian part of Borneo). Along with fast deforestation, population of wild jelutung is decreasing. In the era of degraded peatland restoration, jelutung was promoted to be planted in reforestation and afforestation.

The Global Forest Resources Assessment 2000 (FRA 2000) provides a comprehensive and up-to-date view of the world's forest resources at the end of the second millennium. It is the result of the collective efforts of the countries of the world. This major undertaking was based primarily on information provided by the countries, supplemented by state-of-the-art technology to verify and analyse the information and to make the results accessible to the world through the Internet. The FRA 2000 process emphasized collaboration and transparency.
