Abstract

The threatened species categories used in Red Data Books and Red Lists have been in place for almost 30 years. The 香港六合彩开奖结果现场直播 Red List Categories and Criteria provide an easily and widely understood system for classifying species at high risk of global extinction, so as to focus attention on conservation measures designed to protect them. This latest version of the classification system was adopted by the 香港六合彩开奖结果现场直播 Council in February 2001 and reflects comments from the 香港六合彩开奖结果现场直播 and SSC memberships and the final meeting of the Criteria Review Working Group.
