摘要:

参考IUCN Red List Categories and Criteria, Version 3.1的等级和标准, 我们于2010年3月至2012年12月对251种(含种下分类群)国产裸子植物的濒危状况进行了评估, 并依据最新的研究动态, 对结果做了少量修订。结果显示极危37种, 濒危35种, 易危76种, 无危87种, 数据缺乏16种; 受威胁种类占评估裸子植物总数的59%。生境退化、分布面积过小和过度利用是主要的致危因子。结合实际保护案例, 我们提出裸子植物濒危物种保育应有针对性措施, 过度保护会进一步导致它们的濒危。

Abstract:

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.
