Invasive Species Removal (March 9, 2019)


The City of Delaware Public Utilities and Parks and Recreation Departments, in coordination with the Olentangy Watershed Alliance (OWA) hosted an invasive species removal event at Mingo Park. We removed bush honeysuckle, a deciduous shrub that was first introduced in the U.S. in the mid-to-late 1800s from Europe and Asia. This shrub can tolerate varying amounts of sunlight and can aggressively grow in place of other native species. Once removed, native trees were planted in the honeysuckle’s place which will provide better food and habitat for wildlife.
