Ferns are a large and conspicuous component of the plant diversity of Thailand with an estimated 670 species. This is about 5-7% of the total vascular flora of Thailand, and a significant proportion of the world's fern flora which is estimated to be between 9,000 and 12,000 species.
The Royal Botanic Garden Edinburgh, in collaboration with the Forest Herbarium Bangkok and Chulalongkorn University in Bangkok, is currently developing a website and multi-access key to identify all of the ferns of Thailand. This key, and a comprehensive information system on Thai ferns, will eventually be made available at this site. The principal collaborators on this project are Stuart Lindsay and David Middleton, of the Royal Botanic Garden Edinburgh, Somran Suddee, of the Forest Herbarium Bangkok, and Thaweesakdi Boonkerd, of Chulalongkorn University.
