Propagating Framework Trees to Restore Seasonally Dry Tropical Forest in Northern Thailand
One issue of concern in native species reforestation is the lack of information on propagation and nursery practices of native seeds and seedlings.
Research Goals & Methods
This research presents data on the germination and performance of ten native species that were formerly classified as possible "framework" species to be used in reforestation in northern Thailand.
Conclusions & Takeaways
All species had a germination rate of over 35%.Castanopsis acuminatissima and Lithocarpus craibianus grew more slowly and had to wait 550 days to be planted in the subsequent wet season. Ficus glaberrima also germinated slowly and had to remain in the nursery for 16 months. Melia toosendan and Prunus cerasoides having a germination rate above 50% and grew into plants suitable for planting in less than 140 days. Because Melia toosendan seeds are collected in the early dry season, trees are ready for planting by the start of the wet season. For Prunus Cerasoidies, however, the dispersal occurs in the early wet season, one year before ideal sapling planting times. The authors recommend storing Prunus cerasoides seeds for 6 months before germinating because of the expense of caring for saplings that are ready for planting too early (during the dry season). The other five species also performed well in the nursery and were ready for planting within 12 months at the start of the wet season. By providing this scheduling information, the authors hope to help individuals use the correct timing and species for reforesting with native species in Thailand.
