Canada lynx (Lynx canadensis) are among the most endangered felines in North America. They are listed as a threatened species under the United States Endangered Species Act (U.S. Fish and Wildlife Service 2000) and as an endangered species under the Washington Department of Fish and Wildlife (Stinson 2001). The Washington State population of Canada lynx is one of the last and largest remaining populations in the United States and their habitat is located primarily in the northern counties along the southern border of British Columbia (Conservation Northwest 2019). It is estimated that approximately 3,800 km2 of suitable habitat in Washington supports as few as 87 Canada lynx (Koehler et al. 2008). North of the border the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) lists the Canada lynx as not at risk, and the province of British Columbia also considers the species not at risk of extinction (BC Conservation Data Center 2020). Because of the notable difference in status between the two countries there is interest in whether individuals are moving across the border from one habitat to the other.
