tailieunhanh - A survey of vascular plant species in the dry season, Cam mountain, An Giang province

The survey which was conducted in the dry season (from February to April) in Cam Mountain, reported 49 plant species belonged to 45 genera and 29 families. These species include 10 big wood species (G) ( %), 14 small wood species (g) ( %), 7 bush species ( %), 9 creeper species ( %) and 9 herbaceous species ( %). | Journal of Science and Technology 54 (2A) (2016) 64-70 A SURVEY OF VASCULAR PLANT SPECIES IN THE DRY SEASON, CAM MOUNTAIN, AN GIANG PROVINCE Nguyen Thi Hai Ly1, *, Lu Ngoc Tram Anh1, Nguyen Huu Chiem2 1 Resources and Environment Faculty, Dong Thap University, 783, Pham Huu Lau street, Ward 6, Cao Lanh city, Dong Thap, Vietnam Environment and Natural Resources Management Faculty – Can Tho University, 2 3/2 Street, Ninh Kieu District, Can Tho city, Viet Nam * Email: nguyenhaily2009@ Received: 1 April 2016; Accepted for publication: 15 June 2016 ABSTRACT The survey which was conducted in the dry season (from February to April) in Cam Mountain, reported 49 plant species belonged to 45 genera and 29 families. These species include 10 big wood species (G) ( %), 14 small wood species (g) ( %), 7 bush species ( %), 9 creeper species ( %) and 9 herbaceous species ( %). There are 33 species used for herbal medicines, 12 species for wood fire, 11 species for fruit, 10 species for household tools and 9 species for food. Pterocarpus macrocapus Kurz is the species that listed in Viet Nam Red Data Book (2007). The average value of Margalef (d) and Pielou (J’) indexes are ± and ± , respectively. There are % quadrates which (d) and (J’) indexes are higher than Margalef (d) and Pielou (J’) indexes. The Shannon – Weiner (H’) index of % quadrats is higher than the average value of Shannon - Weiner index ( ± ). The number of species at quadrats O1T1, O3T1 and O1T2 are more diverse than other quadrats. The transect 1 (T1) to the east is more diverse than the transect 2 to the west of Cam forest. Key words: Plant diversity, vascular plant, Cam Mountain. 1. INTRODUCTION Biodiversity has been addressed by the scientists for more than a century. Interest in the subject increased in the early 1980s, when accelerated habitat destruction and species loss raised international concern and resulted in 1992 in the adoption of
