Distribution of the invasive Polynesian rat, Rattus exulans (Peale), in Taiwan
Plant Protection Bulletin (Taipei) 45 (2), 163-167
Abstract: The Polynesian rat (Rattus exulans (Peale)), a widely distributed rat in Southeast Asia and Pacific Islands was found in Taiwan in 1999, and was thought to be a new invader of unknown origin. From preliminary survey data, it seems to be distributed in Chian Village, Hualien on the northern bank of the Mugua Stream. A survey was made from January to November 2003 to study the distribution and status of R. exulans in that area and further to propose an eradication strategy. The survey data indicate that R. exulans is distributed in the area bordered by Highway 9 on the west, Jian Stream on the north, and Mugua Stream on the south. No R. exulans was captured in the field on the west side of Highway 9 during this survey.
