Invasive Plant Management Workshop

Held February 11, 2010, at the Chicago Botanic Garden
Organized by the Lake County Forest Preserve District

image: logoThe 2010 Invasive Plant Management Workshop, organized by the Lake County Forest Preserve District and hosted by the Chicago Botanic Garden, provided attendees an opportunity to learn about invasive plant management strategies that are being implemented within the Chicago Region. Species covered included those that are already locally widespread as well as those that are just beginning to spread into the region. Special attention was given to chemical control strategies, both alone and in combination with other management approaches. Several speakers also discussed innovative tools and equipment that are being developed for management of invasive plants.

Each of the workshop's presenters delivered oral remarks together with their PowerPoint presentation.
