The vascular flora of the Research Forest in Yen Tu, Quang Ninh was assessed between
2005 and 2006. In the area under review, 721 species belonging to 425 genera and 154 families
were identified. Among these species, these are 9 Lycopodiophyta, 34 Polypodiophyta, 8
Gymnospermae and 670 Angiospermae species (577 Dicotyledonae, 93 Monocotyledonae). The
richest 3 families are Euphorbiaceae with 52 (7.2%) species, Asteraceae with 30 (4.2%) species
and Moraceae with 30 (4.2%) species. The richest genus is Ficus L., (22 species) followed by
Syzygium Gaertn., (8 species) and Dioscorea L., (7 species). When the flora of the area is analysed
by Raunkiaer’s life form system, the results are as follows: phanerophytes 596 (82.7%),
chamaephytes 20 (2.8%), hemicryptophytes 15 (2.1%), cryptophytes 37 (5.1%), therophytes 37
(5.1%), and unknown 16 (2.2%) species, respectively. |
