Wisconsin Council on Forestry - Invasive Species Best Management Practices:

Wisconsin Council on Forestry.

Invasive exotic species present what may be the greatest threat to the long-term health and sustainability of Wisconsin's forests. Human activities such as trading of goods, travel, gardening, and recreation have resulted in the introduction of many non-native plant and animal species to the state. The Council created the Forestry Invasives Leadership Team to develop voluntary best management practices (BMPs) to help control the spread of invasive species.
