Low technology tree propagation and the restoration of natural forest ecosystems

Background

This chapter outlines the need for reforestation in Southeast Asia, with a focus on Thailand, and describes the nursery and propagation processes necessary for successful production of native species for reforestation. The paper focuses mainly on the Forest Restoration Research Unit (FORRU), which was established to address the need for information on native species for reforestation, especially information on seedlings and nursery practices. Most information on propagation available before the creation of FORRU referred to exotic species.

Conclusions & Takeaways

The authors cite the importance of restoration for in situ conservation and the fact that the biological and social aspects of restoration have not been given appropriate attention. Recent policies in Thailand have strongly encouraged native species reforestation, but lack of information on propagation and planting techniques has slowed the process. In contrast, FORRU advocates reforestation with native species, known as “enrichment planting” or “accelerated/assisted natural regeneration.” FORRU also stresses the importance of making this information available to local people. The authors conclude highlighting the importance of compiling information on “framework species,” or species most appropriate to plant to complement natural regeneration.
