PLANT DIVERSITY IN SPECIAL USE FORESTS, QUANG NAM PROVINCE

Abstract

Quang Nam province is the intersection of the flora and fauna of the North and the South, so it has a unique biodiversity and is important for the development of the province. However, current social, economic and environmental issues are putting a lot of pressure on the natural ecosystem. In order to rationally use biodiversity resources in a sustainable way for socio-economic development and environmental protection of the province, one of the urgent first steps is to build a database on biodiversity in general, and flora biodiversity in particular. This study has analyzed and evaluated data on flora diversity in Nature Reserves (NRs), National Parks, Flora and Species Conservation Areas in Quang Nam Province recorded in more than 30 years, research works and documents of domestic and foreign, as well as additional investigation in the field. The results of data analysis have shown that there are at least 1,925 species of higher plants belonging to 204 families, 82 orders, and 9 classes in 6 divisions (Psilotophyta, Lycopodiophyta, Equisetophyta, Pteridophyta, Pinophyta, Magnoliophyta,). Results of six investigations, on 59 routes and 54 OTCs (1,000 m²) in Song Thanh National Park, Tay Giang Forest Flora, Saola Nature Reserve, Elephant species and habitat conservation area, Cu Lao Cham Biosphere Reserve, Ngoc Linh Nature Reserve have added 827 species (with two new species: Leptomischus multiflorus và Raphiocarpus taygiangensis) belonging to 155 families, in 5 groups of flora: Psilotophyta, Lycopodiophyta, Pteridophyta, Pinophyta, Magnoliophyta, including 827 species not mentioned in the list of analyzed documents. The study also shows the diversity of life forms, use value and conservation status of natural flora in nature reserves in Quang Nam province.
