Results The mixed forest plantations have been established as a greenbelt in the farmland surrounded by various forms of development, including agricultural areas, tourism establishments, residential communities and resorts. Mixed transplanting with seedlings in Phase 1 in the area free from old stumps of Casuarina and less weeds was a successful establishment of mixed vegetation (Figure 1). Now the whole plantation has been developed as a camping area and convention hall for tourists and visitors. Mixed transplanting with saplings in Phase 2 provided a remarkable landscape inside the 74 THE ASIA REGIONAL FORUM ON BIODIVERSITY plantation (Figure 2). The majority of exotic species could not survive due to pests and poor soil structure except for Mahogany (Swietenia macrophylla King). It was the only plant species that could grow and create a good atmospheric landscape with a dense and long lasting green canopy almost all year round. It was also observed on its ability for natural regeneration inside the forest plantation since 2008. Mahogany has survived and reproduced several generations of forests in Thailand since it was introduced in the country as a shaded tree by Henry Alabuster (1836-1884), one of the first British diplomats to the Court of Siam who became advisor to King Rama V in 19th Century.
