2nd National Invasive Rodent Summit
October 19-21, 2004

The Second National Invasive Rodent Summit held on October 19-21, 2004, at the National Wildlife Research Center (NWRC) in Fort Collins, CO, was a follow-up to the “Rat Summit” held in San Francisco, CA, in 2001. Like the first “Rat Summit,” this conference emphasized the management of rodents to conserve plants, other wildlife and habitats. Presentations also highlighted the importance of rodent predators as part of a successful integrated pest management strategy. The 105 attendees were from 10 countries and territories and 23 states. Attendees included scientists and managers from government and private sector land and resource management agencies and groups. Special sessions covered nutria management, rodenticide risk assessment techniques, rodent eradication efforts on islands, rodent control in mainland habitats, and the role of rodents in disease transmission. A member of the executive committee of the National Invasive Species Council made a plenary presentation and the keynote talk was provided by Dr. William B. Jackson of Bowling Green State University on “A Century of Rat Control.” The comments and evaluation forms from attendees suggest that the Invasive Rodent Summit was a huge success.
