South China Botanical Garden (SCBG), Chinese Academy of Sciences (CAS) is one of the oldest botany research institutions in China. SCBG, formerly known as the Institute of Agriculture and Forestry (IAF), Sun Yat-Sen University, was founded in 1929 by renowned botanist Academician Chun Woon-Young. In 1954, the affiliation of IAF was changed to CAS and was renamed South China Institute of Botany (SCIB), CAS. In 2003, SCIB was renamed to its current name SCBG. In 2022, SCBG was upgraded to South China National Botanical Garden (SCNBG) as one of the first two National Botanical Gardens launched and approved by the State Council of China. During the period of SCIB, China's first national nature reserve--the Dinghushan National Nature Reserve was established in 1956.
