| red list The series of publications produced by the International Union for the Conservation of Nature and Natural Resources (IUCN). They provide an inventory on the threat to rare plants and animal species. Information includes status, geographical distribution, population size, habitat and breeding rate. The books also contain the conservation measures, if any, that have been taken to protect the species. There are five categories of rarity status: endangered species; vulnerable organisms, which are those unlikely to adapt to major environmental effects; rare organisms, which are those at risk because there are few of them in the world, such as plants which only grow on mountain peaks or on islands; out of danger species, which were formerly in the above categories, but have had the threat removed because of conservation actions; and indeterminate species, which are the plants and animals probably at risk, although not enough is known about them to assess their status | 红色名单 (自然和自然资源保护国际联盟(IUCN)出版的一套出版物。他们出版了濒临灭绝的植物和动物的详细目录。信息包括状态、地理分布、数量、习性和繁殖率。如果已经有任何已经用到的保护种群的方法，书中也有记录。稀有状态分成五类：濒临灭绝的物种；脆弱的物种，指那些不能适应主要的环境影响的物种；稀少物种，指那些因为存在量很少而有风险的物种，例如只生长在山峰上的或岛上的植物；不危险的物种，指不在前面几类中的物种，因为保护行动解除了威胁；不确定的物种，指可能有危险的植物和动物，但对它们的物种情况了解不够，不能评价它们的状态。) |
