INVASIVE PLANT SPECIES: NON-NATIVE SHRUBS REMAIN PRIORITY, BUT OTHERS CAN CAUSE PROBLEMS IN CHICAGO REGION
Invasive plant species continue to threaten ecosystems across the Chicago region, with non-native shrubs such as common buckthorn and invasive honeysuckles posing the greatest concern. These aggressive plants spread rapidly, displacing native vegetation and disrupting habitats that support wildlife, pollinators and birds. Other invasive species, including garlic mustard, Callery pear, lesser celandine and teasel, also contribute to biodiversity loss.

Education and awareness remain essential to protecting healthy, diverse and resilient natural landscapes.
