Know Your Invasive Species

Did you know Feb. 21 ‒ 27 is National Invasive Species Awareness Week? During the winter here in DuPage County, District crews work to remove invasive woody shrubs from our preserves. Both common buckthorn and glossy buckthorn are main invasive species targets of the District's removal work.

Another woody invasive is honeysuckle. Because both buckthorn and honeysuckle grow quickly, they rob soils of moisture and nutrients. The resulting bare soil is susceptible to erosion and is uninhabitable by most wildlife. They also spread quickly, creating low, dense canopies that prevent sunlight from reaching native shrubs, young trees, wildflowers and other groundcover below. This allows them to effectively smother native vegetation.

Find out more about other invasive species here. If you would like to volunteer with us, register for one of our volunteer restoration workdays
