Welcome!

The Wild Rivers Invasive Species Coalition (WRISC) is a cooperative invasive species partnership operating in northeast Wisconsin and the Upper Peninsula of Michigan.  The partnership consists of a wide range of partners and members from local, state, tribal, and federal agencies, land managers, utility companies, civic organizations, businesses, and individuals, all interested in the education and management of invasive species in the five county WRISC area. 

Non-native invasive species can have devastating ecological and economic impacts to communities.  Industries such as forestry, agriculture, and outdoor recreation are all at risk, as are native fish and wildlife habitats.  Invasive species are often widely dispersed across the landscape, and do not respect geopolitical boundaries.  As such, this coalition strives to combine multi-agency resources and expertise to coordinate education and management of invasive species across borders, promoting best management practices that will help to slow the spread of these invaders.
