Knox-Lincoln and Waldo Soil & Water Conservation Districts and Maine Department of Agriculture, Conservation & Forestry are sponsoring an indoor/outdoor workshop on how to manage invasive plants in the Abbott Room of the Belfast Free Library, 106 High St., Belfast, Monday, July 20, from 9 a.m. to 12:30 p.m.

Invasive plants can overrun natural areas, crowding out native species and changing wildlife habitats. Join Nancy Olmstead, invasive plant biologist with the Maine Natural Areas Program to learn about invasive plant management strategies, including how to map, ID, prioritize and control selected species.

Following the indoor presentation, participants will carpool to the Coastal Mountains Land Trust Stover Preserve in Belfast, where Helen Burlingame, invasive plant volunteer, will lead a tour of an ongoing shrubby honeysuckle management project. This program is approved for two hours of pesticide recertification credits by the Board of Pesticide Control.

Space is limited and registration is required. Registration fee of $10 includes handouts, coffee and snacks. For more information and to register, call 596-2040, email, or visit to register online.
