Abstract

The paper provides updated and thoroughly databases on vascular flora and vegetation types at elevational belt above 2,800m of Hoang Lien Son mountain range (Lao Cai province) for plant diversity conservation and sustainable development planning. The research results show that in this belt, there are 126 species, 82 genera, 46 families belonging to 3 vascular divisions: Polypodiophyta, Pinophyta and Magnoliophyta. In particular, Magnoliophyta has absolute dominance with 123 species (accounts for 97.6% of the total species of study area). 6 valuable and rare species (5% of total species) in Vietnam Red Book, Red List of IUCN, 13 endemic species (10.3% of total species) and 37 useful species (29.4% of total species) are recorded. Among them, there are 7 endemic species only in Hoang Lien Son area, 31 medicinal species, 9 ornamental species and 5 food species. 5 vegetation formations at elevation belt of 2,800 m are described. They are typical and unique to Hoang Lien Son high mountain area that should be prioritized to protect from human impacts, especially overload tourism development.

Keywords: Flora, Hoang Lien Son, vascular plant diversity, vegetation, plant resources.
