Yen Tu National Forest boasts a rich ecosystem of flora and fauna. Notably, among the plant species in the forest are several ancient tree species closely associated with the spiritual journey of King Tran Nhan Tong at Yen Tu, as well as with the monastic community and Buddhist followers. These include the Xich Tung (red pine), Thanh Tung (pine), Tung La Han (Arhat pine), and the centuries-old golden apricot tree (Mai Vang), which are deeply intertwined with the history and spiritual significance of the region.
