Based on the IUCN Red List Categories and Criteria (Version 3.1), we assessed native gymnosperm species and infraspecific taxa found in China between March of 2010 and December of 2012. Results indicated that 37 species were critically endangered (CR), 35 species were endangered (EN), 76 species were vulnerable (VU), 87 species were of least concern (LC), and 16 species were data deficient (DD). Up to 59% of the 251 native species of gymnosperms found in China were classified as threatened. Threatening factors impacting gymnosperm species in China were ascribed into seven categories, among which habitat degradation, restricted distribution, and over exploitation were listed as the top three threats. According to results of red list assessments and conservation practices of gymnosperms in China, we propose that conservation of endangered gymnosperm species should have a targeted program. Otherwise, over-protection could result in additional threats to endangered species.

Key words: red list, assessment, threatened species, threatening factors
