Thanks for your question and raise good point of FORRU using framework species in the northern Thailand. In the northeast of Thailand, the weather condition is more drougth than the north with poor soil fertile. It is important to select the native tree species which tolerant to drought as Pak Wan (Melientha suavis), Pek (Vietnamosasa pusilla. These plants have underground rhizomes so preventing them from being burned by wildfires that occure almost every year.
