Na Hang Nature Reserve was established under Decision No. 274/UB-QD dated 9th
May 1994 by the People’s Committee of Tuyen Quang province. About 68% of the area is
tropical moist forests. Of these, about 70% are limestone forest, and the rest are lowland
evergreen forest. In 2006, Nguyen Nghia Thin and his colleagues identified and listed 1,162
species of plants in the Na Hang Nature Reserve, many of them were listed in the Vietnam
Red Data Book (2007) such as Garcinia fragraeoides, Excentrodendron tonkinense,
Chukrasia tabularis, Markhamia stipulata etc.
Beside the research resultsof some authors at the Forest Inventory and Planning
Institute, Birdlife International program; Nguyen Nghia Thin and Dang Quyet Chien (2006);
Nguyen Anh Tuan et al. (2012); so far, there is no comprehensive research on medicinal
plant resources, especially the promising species in Na Hang Nature Reserve. On the other
hand, medicinal plant resources in Na Hang Nature Reserve are becoming increasingly
scarce, some of which are endangered due toindiscriminate and planless exploitation and.
The potential and prospects of medicinal plant resources and indigenous knowledge of
indigenous peoples in Na Hang Nature Reserve are plentiful and varied; But these studies
are few and far from complete. Research on the scientific basis for conserving, restoring and
sustainably using the diversity of medicinal plants in Na Hang Nature Reserve, Tuyen
Quang province, is an urgent, critical issue. scientific significance and high economic and
social value. Based on this situation, the author conducted the study “Research on
medicinal plant resources to propose solutions for conservation and sustainable use of
some valuable species in Na Hang Nature Reserve, Tuyen Quang province”.
