Woody Invasive Species Control in Natural Heritage Parks

The City of Windsor continues to increase efforts to control invasive woody species in tallgrass prairie and oak savanna ecosystems within Oakwood Natural Area, Spring Garden Natural Area, Tallgrass Prairie Heritage Park, Ojibway Park, Black Oak Heritage Park, and significant habitat areas at Dr. Bruce and Kathryn White Memorial Park. 

Weather permitting, the work will begin as early as November 16, 2026, and continue throughout the winter months but not beyond March 15, 2027. This public notice is in accordance with the Natural Resource Management exception to the cosmetic pesticide ban that affects the Parks Department.

Species included in the targeted control efforts are Autumn Olive, Honeysuckle, Multiflora Rose, European Buckthorn, Black Locust, and Tree-of-Heaven. Methods will follow the best management practices for each species and include direct and targeted application of the following pesticide registered under the Pest Control Products Act (Canada): Credit Xtreme (product # 29888), containing the active ingredient glyphosate. This product is not sprayed; it is directly applied to cut stumps and soaks in quickly (approximately 30 minutes).

Closures of park or trail systems will not be necessary. Park users are asked to stay on the authorized trail and keep pets leashed at all times.
