All known species of Angiosperms in China were evaluated according to the IUCN Red List Categories and Criteria: Version 3.1, Second edition and the Guidelines for Application of IUCN Red List Criteria at Regional and National Levels, Version 4.0. Of the 30,068 species evaluated, 21 species were found Extinct (EX), 9 species were Extinct in the Wild (EW), 10 species were Regionally Extinct (RE), 518 species were Critically Endangered (CR), 1,152 species were Endangered (EN), 1,693 species were Vulnerable (VU), 2,538 species were Near Threatened (NT), 21,132 species were Least Concern (LC), and 2,995 species were Data Deficient (DD). The results show that 3,363 species, representing 11.2% of the evaluated species, were identified as threatened (CR, EN and VU). The main portion of threatened species occurs below 2,000 m elevation in southwestern and southern China. Habitat loss and degradation, over-collecting by humans, and intrinsic factors are the three leading threats to angiosperms in China. Comparisons of the status of taxa on this Red List to those evaluated by Wang & Xie (2004) show changes in the names and categories of some taxa due to land use pressures, the impact of conservation measures to improve the status of some species as well as new information, such as from taxonomic revisions. Therefore, there is a need for future data collection and reevaluation of the red list.
