SYMP 16 - Invasive Species with Cross-Border Spread: Negotiating the International Divide

Thursday, August 11, 2011: 8:00 AM-11:30 AM
Ballroom C, Austin Convention Center
Organizer: K. Cuddington
Co-organizers: Julie L. Lockwood and Martha F. Hoopes
Moderator: K. Cuddington
Many pernicious invasive species cross international borders with aplomb. The movement of these species can lead to prediction, detection and management difficulties as different sets of regulations and economic practices affect species establishment and movement. For example, Giant Hogweed (Heracleum mantegazzianum), an invasive species with a clear human health hazard, and has been regulated in the US for over a decade, but is not yet listed as noxious weed species in Canada, and was available commercially there until very recently. We hope to identify common issues by inviting experts on a range of species (plants to fish) to address the particular difficulties posed by cross-border invasives. Speakers from both sides of the US/Canada border will each address an aspect of species invasion from their unique national perspective. Topics will range from modeling the spread of invasive species crossing national boundaries, to the difficulties in implementing effective management policies when international politics and trade are involved.
