RESEARCH ON DIVERSITY OF FOREST TREE SPECIES AND PROPOSE THE SOLUTIONS TO PRESERVE BIODIVESITY IN NATRUAL RESERVE MUONG LA, SON LA PROVINCE

Abstract

The results of additional surveys on plant diversity in Muong La nature reserve, Son La province have recorded 1,015 plant species, belonged to 5 plant phyla (Lycopodiophyta, Polypodiophyta, Equisetophyta, Pinophyta, Magnoliophyta). Recorded 10 families with a large number of species were Euphorbiaceae, Asteraceae, Poaceae, Fabaceae, Caesalpiniaceae, Fagaceae, Annonaceae, Dryopteridaceae, Rubiaceae, and Orchidaceae. The plants species were distributed in 8 habitat types including natural forest, plantation forests, shrublands, bamboo glades, grasslands, agriculture, residential and water areas. Plant species living in 5 basic life forms include upper buds, ground-close buds, semi-hidden buds, hidden buds, and annual buds. The research results also recorded 21 species belong to the IUCN Red List (2020), 31 species in the Vietnam Red Book, and 56 species in the  Decree No.84/ND-CP (2021). The study has also evaluated the main threats to biodiversity in the study area and recommended 4 main solution groups  to sustainably preserve biodiversity for Muong La nature reserve.
