摘要:

本文阐述了中国苔藓植物濒危等级的评估原则。这一原则主要参考“IUCN物种红色名录濒危等级和标准(3.1版)”, 同时也吸收了其他苔藓学家的评估指南和结果。作者将10年内发表的新分类群暂评为数据缺乏(DD)等级, 根据馆藏标本份数估计栖息地物种成熟个体数。在此基础上, 对3,221个中国苔藓植物分类群进行评估, 结果为: 极危(CR) 16种; 濒危(EN) 58种; 易危(VU) 112种; 近危(NT) 214种; 无危(LC) 1,900种; 数据缺乏(DD) 921种。极危、濒危和易危等级的受威胁苔藓植物合计186种, 占中国苔藓植物种数的5.77%。

Abstract:

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).
