This Brisbane box (Lophostemon confertus) woodland had endured two hill fire in 1990 and 2014. Some of the Brisbane boxes were so tough that they regrew using epicormic shoots. However, most of them are weak. Many of them cannot withstand typhoons happen during every summer. On the other hand, the understory was conquered by thickets of weeds, mainly the Dicranopteris pedata and Lepidosperma chinense. The fast growth rate and strong dispersal ability of these R-selected species have affected the survival of native species. In order to effectively enhance the biodiversity there, we planted species that have stronger survivability and endurability, such as Polyspora axillaris, Garcinia oblongifolia, and Daphniphyllum calycinum.
