More Details Less Details Locality: Bhutan (27.425290, 89.650010) Abstract: The Royal Botanical Garden, Serbithang was established in 1999 under National Biodiversity Centre, Ministry of Agriculture and Forests, Serbitang as an ex-situ plant conservation area and to commemorate the Silver Jubilee Celebration of the 4th King of Bhutan, His Majesty Jigme Singye Wangchuck. One of the main mandates of the Royal Botanical Garden Serbithang (RBGS) under the National Biodiversity Centre is ex-situ conservation of native plants. Since the establishment of the garden, the living collections of orchids, trees, shrubs and herbs have steadily increased. The garden has grown from degraded pasture land to a dense forest with more than 500 plant species, comprising trees, shrubs and herbs from sub-tropical, temperate, and sub-alpine regions of the country. In order to document the diversity of collections at the garden as well as to educate visitors, this checklist documents the diversity in the garden. Reference: Gyeltshen, N., S. Dema, K. Tobgay, T.
