In this paper, the assessment principles of the endangered categories of Chinese bryophytes are expanded. This principle mainly refer to “IUCN Red List Categories and Criteria. Version 3.1”, and also include results from other bryologists. The authors propose that those taxa published in the past ten years temporarily be classified as Data Deficient (DD), and estimate population sizes for all taxa be made based on herbarium specimens. A total of 3,221 taxa of Chinese bryophytes were evaluated based on the above principles and methods. Sixteen species were identified as Critically Endangered (CR), 58 species as Endangered (EN), 112 species as Vulnerable (VU), 214 species as Near Threatened (NT), 1,900 species as of Least Concern (LC), and 921 species are classified as Data Deficient (DD). Overall, 186 species of bryophytes (5.77% of the bryophytes found in China) were identified as threatened (including CR, EN, and VU).

Key words: IUCN Red List, threatened taxa, assessment, bryophyte, China
