PRELIMINARY RESULTS OF PLANT COLLECTION AT CHIENG SINH FORESTRY RESEARCH STATION - FOREST SCIENCE CENTER OF NORTHWESTERN VIETNAM

Abstract

From 2019 to 2021, the Plant Collection Garden at the Chieng Sinh Silviculture Research Station planted and collected 30 new species belonging to 19 families, including 17 rare species listed in the Vietnam Red Book as endangered and critically endangered. The collected species had three different life forms: large trees, medium - sized trees, and small trees. These species belonged to 7 different utility groups, with timber trees accounting for more than 50% of the total collected species. The survival rate of these species ranged from 71.05% to 100%. The average growth rate of most species was below 0.5 cm/year. However, the species Terminalia myriocarpa showed a significant growth rate of 1.02 cm/year. By 2023, the species planted in the collection garden from 2019 to 2021 were classified as slow-growing according to Circular 22/2021/TT-BNNPTNT. Results from building a Plant Collection Garden at the Chieng Sinh Silviculture Research Station has made a significant contribution to the conservation and development of biodiversity. To upgrade and maintain the Plant Collection Garden, management and care of the plant species must continue to improve to ensure sustainable growth and development of the plants in the future.
