"Between 1993 and 1997, the Canadian Wildlife Service (CWS) eradicated Norway rats(Rattus norvegicus) from Langara Island, Haida Gwaii, to restore the island as habitat for breeding seabirds. The main eradication campaign occurred in 1995. In 1999, the Ancient Murrelet (Synthliboramphus antiquus) colony was re-surveyed to assess population-level response to rat eradication. In addition, surveys of upland birds carried out in 1993 were repeated, and traps were set out to determine whether rats had recolonized the island"--Abstract, p. i. Also available in print format.
