Carl E. Bonnell Wildlife Management Area consists of three Natural Plant Community types. This includes an upland consisting of Red Oak, Sugar Maple, and Basswood forest. The majority of the WMA is made up of two wetland types; this includes willow dogwood shrub swamp and black ash, yellow birch, red maple, basswood swamp.
Anoka Conservation District started buckthorn management at Carl E. Bonnell this winter. This involves removing large buckthorn with a chainsaw and treating smaller buckthorn with a basal bark treatment technique. Both common and glossy buckthorn have been found in the WMA.
Both glossy and common buckthorn are invasive species and are on the Minnesota Restricted Noxious Weed list. Removing and treating buckthorn is important to protect ecosystems. Buckthorn grows thickly and outcompetes native plants for light and nutrients once established.
