Flora was known as 543 species, that belonging to 356 genera, 110 families and 4 divisions of vascular plants. Eleven families content over 10 species in each one. There were 27 threatened species in this survey including 11 species in Vietnam Red Data Book, 4 species in IUCN Red List and 19 species in 32 Vietnamese government Decree.
Thirty four species were known (in general) that exploited by Caovit Gibbon distributed in the survey area.
There were 7 types of vegetation that were described and among them, 15 plots (total of 906 trees) were make to assess the forest structure and life-space for Caovit Gibbon.
The forest structure and the resources of plants exploited byCVG seems be good forCVG in a long time and ensure for the development of them population.
The study of this survey area show that the conservation there is on good way. It is need to continue the conservation activities, training for Conservation protected guards (CPGs) about the conservation and investigation. This ranger is working ineffective. They have not supported for study, special in investigation of flora and observation the behaviors ofCVG. Continue the education for local people about the value of this rare resource, support them in development of house-economic, preventing impact to forest andCVG's habitats. Some time, local people went go to the forest to fire the charcoal, to hunter or exploit the rattans, firewood or orchids, special Paphiopedilum spp., one rarely species in CITES, 32 Vietnamese government Decree, so the CPGs is needed to reinforce both in activities and persons. In addition, every day, local people went to the forestry protected post to grow the corns, they need to fire the wood to cook and may be the brought the invasive plants to the core area, there were many common weeds surrounding the forestry protected post. The invaders will transgress the habitats of negative plants. It is a disaster for the negative on limestone there.
n this survey, the resource of plants exploited byCVG were collected and determined only, not assessed the reserves in the forest. In additional, it is need to continue the study and survey to assess the comprehensively resources that ensure the sustainable development of populations ofCVG in the future.
