Population trends, distribution and conservation status of semi-domesticated reindeer (Rangifer tarandus) in China

摘要

The reindeer (Rangifer tarandus tarandus) is listed as a species of "least concern" on the Red List of Threatened Species of the World Conservation Union (IUCN). It is distributed in the northern part of China and semi-domesticated in the region. Here we present a comparison of the historical and current distribution and numbers of reindeer in China, as well as an assessment of the factors limiting population growth. Based on this information we explore potential protective measures for reindeer in China. The reindeer has been herded extensively by the Ewenki people, the only people to do so in China. Reindeer in China originated from the Wenduosenlin tundra highlands of Siberia. Capable of migrating more than 3000 km/year, the reindeer moved from the highlands to the Weitimu river during the 16th century and on to the Northeast area of China in 1654. Since 1957, 600 reindeer have settled in Qiqian in Inner Mongolia, and from 1965 more than 900 reindeer migrated from there to Mangui. In response to frequent flooding and a fluctuating reindeer population in the Mangui region, in 2003 the Ewenki people and more than 260 reindeer translocated from there to Aoluguya. Currently, eight meta-populations of reindeer comprising 773 individuals inhabit in the Arctic region of China. The reindeer population peaked in the 1970s at more than 1080 animals, but declined markedly from 1998 onwards mainly as a result of inbreeding, poaching, predation and tourism. The Chinese government's interest in wildlife protection is increasing, as evidenced by the introduction of wildlife protection laws and regulations, the importation of new reindeer varieties from Russia and the joining of the Association of World Reindeer Herders. However, natural reserves and national parks have still not been established within the reindeer's range in China to conserve this fragile population.
