Invasive Species and Alternative Control Methods Workshop

The NCWMA hosted a daylong workshop on Invasive Species and Alternative Control Methods on July 20th at the Northern Great Lakes Visitor Center in Ashland, Wisconsin. Forty-five people attended the event. The day was jam-packed with interesting presentations and field trips. Thanks to everyone who attended and presented! Thanks to the Whittlesey National Wildlife Refuge for bus transportation and to the U.S. Forest Service for providing a great venue for the event.
