A summary of the classification of Chase et al. (in tree form) is available here
Of 1855 species that have been assessed for the Global Redlist, 209 are critically endangered, 422 are endangered and 234 are vulnerable (as of December 2021)
All orchids are listed on CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora), but many are still subject to unsustainable/illegal colllection for food, medicine or horticulture
More than 70% of all species (plants and animals) on CITES Appendices 1 and 2 are orchids
