The Vietnamese tropical monsoon forest's trees

Vietnamese tropical monsoon forest's trees are belonging to 120 families and 3140 species - this is 44% from total forest flora. In the monsoon forests approximately 330 tree species are forming the upper part of the forest canopy (strata), 2490 tree species - the middle part and 320 species - the undergrowth part. Some tree species are quiet rare in the forests, another species are forming a base of the forest stand, dominating and co-dominating there. Accordingly in Vietnam there are monodominante, polydominante and clear species forests. A vertical structure of the forest stands is divided to a simple structure with 1 or 2 tree layers (strata), a middle complicate structure with 3 layers and complicate structure with 4 or 5 tree layers.
