Forest Service scientists help organize international meeting.

Eastern Forest Environmental Threat Assessment Center research ecologist Frank Koch and Northern Research Station research biologist Robert Venette, and international colleagues co-organized the sixth annual International Pest Risk Mapping Workgroup (IPRMW) held July 23-26 in Norway. 

The IPRMW is a group of like-minded scientists focused on improving the pest risk mapping processes through the application of rigorous, innovative research. The IPRMW includes government and university scientists from Europe, North America, Australia, New Zealand, and elsewhere.

Pest risk maps provide powerful visual displays of where invasive alien species might arrive, establish, spread, or cause harmful impacts. These products are used to inform decisions about whether to allow imports of commodities that might carry unwanted pests and diseases, whether to impose quarantine restrictions on the  movement of goods within a country, or where to conduct surveillance for recent invaders.

The IPRMW meeting addressed challenges of incorporating climate change into long-term risk projections; calculating the economic effects of species invasions, and quantifying uncertainties in forecasts about the future course of species invasions. 

Workshop participants represented Australia, New Zealand, Canada, England, Finland, Norway, the Netherlands, Hungary, Italy, and the United States. The meeting was sponsored by the Co-operative Research Program of the Organization for Economic Cooperation and Development.
