The Pu Luong Nature Reserve has discovered 130 Trai ly trees, 25 Dinh tung trees and 120 Tra hoa trai mong trees in Pu Luong forests. It has surveyed 217km of 47 forest lines to explore the distribution and threats to these species. Meanwhile, it has fully researched the biological and ecological characteristics of these floras, and built 12 monitoring lines and 30 standard plots to monitor them in the buffer zone and core area of the reserve. The reserve has also taken measures to improve locals and forest rangers’ capacity to recognise these plants, thus encouraging them to engage in the protection of the rare species. To date, 200 Trai ly trees, 150 Dinh tung trees and 200 Tra hoa trai mong trees have been planted in a 0.83-hectare special-use forest of the reserve./.
