Our Invasive Species Program is concerned with many common invasive weeds, such as English ivy and Armenian blackberry, along with the EDRR (Early Detection-Rapid Response) weeds. It’s important to prevent invasive weeds from spreading, as they can easily push out important native plants, and upset the delicate balance needed to support healthy ecosystems for all plants and wildlife.
Below are some common weeds found in our district. We work to remove these species on active restoration projects. If you have these weeds, we can offer advice on how to manage them.
