Research on Medicinal Plant Resources in Cham Chu Nature Reserve, Yen Thuan Commune, Ham Yen District, Tuyen Quang Province

Our investigation has documented 400 medicinal plant species belonging to 309 genera and 117 families across five divisions of vascular plants. The life form composition of plants in the study area comprises five groups. The group with the least number of species is the chamaephytes, with 27 species (6.75%), followed by the therophytes with 35 species (8.75%), cryptophytes with 41 species (10.25%), hemicryptophytes with 45 species (11.25%), and the phanerophytes with the highest number of species at 252 (63.00%). The geographical elements have been determined for 390 species (97.50%), while 10 species (2.50%) remain undetermined. In the study area, 18 medicinal plant species (4.5%) have been identified as threatened and in need of conservation. Among these, 15 species (83.33%) require protection according to the Vietnam Red Book; 5 species (27.78%) are listed under Government Decree 06/2019/NĐ-CP; and 5 species (27.78%) are listed in the 2007 Vietnam Red List of Medicinal Plants. Currently, the medicinal plant resources in the study area are being exploited by local inhabitants and are at risk of depletion if conservation policies and measures are not implemented.
