List of rare and endangered plants and endemic species
Status of flora is crucial for prioritizing and formulating plans on flora conservation and management. Due to some constraints, such aslimitation of flora study in terms of personnel, expertise, budget and policy,research and study under the project titled Flora of Thailand have not been completed yet.
Consequently, Thailand lacks systematic study and development of lists on status of flora for conservation leading to difficulty of conservation activities, such as collection of propagating material and seeds as well aspropagation of threatened flora species.
In 2005, ONEP in collaboration with Office of the Forest Herbariumconducted a survey on flora status in Thailand, aiming to locate and classify status of plants in the country into categories-- endangered, rare and endemic species-- and to compare the result of the study to IUCN Red Data 2010. Information obtained from the study has been used for developing flora checklists, formulating legislation and policy, and working to achieve2010 Biodiversity Target.
As the result of the survey, total numbers of located species are 1410, from 137 families.

| Those species are comprised of 757 endemic species, 15 semi-endemic species, and 638 non-endemic species, most of which are underOrchidaceae (174 species). |
By this, it is expected that AmherstianobilisWall. (Leguminosae-Caesalpinioideae) become extinct. |
The findings of the survey can be applied into development of legislation regarding plant protection, formulation policy on flora habitat conservation, development of GIS database and checklists.
