Taxus chinensis Yew Plantations (Yunnan / Sichuan, China)

Chinese yew tree (Taxus chinensis, T. yunnanensis) plantation system concentrated in Yunnan, Sichuan, and Shaanxi provinces; the primary global source of 10-deacetylbaccatin III (10-DAB) used in paclitaxel and docetaxel semi-synthesis. Chinese yew plantations are managed by provincial forestry enterprises and private agricultural companies supplying Chinese API manufacturers. Taxus chinensis cultivation in Yunnan was developed as a sustainable alternative to Pacific yew bark harvesting after the US near-extinction crisis of the early 1990s. Chinese yew plantations represent the world's largest concentration of the paclitaxel precursor feedstock. Source: https://pubs.usgs.gov/fs/2007/3095/
