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) (20.4 %), 14 small wood species (g) (28.6 %), 7 bush species (17.2 %), 9 creeper species (18.4 %) and 9 herbaceous species (18.4 %). 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 2.45 ± 0.37 and 0.94 ± 0.02, respectively. There are 54.5 % quadrates which (d) and (J’) indexes are higher than Margalef (d) and Pielou (J’) indexes. The Shannon – Weiner (H’) index of 63.6 % quadrats is higher than the average value of Shannon - Weiner index (1.94 ± 0.19). 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.
