More and more often we are faced with exotic (aquatic) plants. These are plants that do not naturally occur in our country and feel very much at home in our environment. For example, the Large Water Pennywort. Exotics grow quickly and displace "native" vegetation and are therefore bad for biodiversity. Because they can grow explosively, they can also impede water supply and drainage. We regularly remove these plants from ditches so that they do not spread further. You can help us by not putting plants from your pond or aquarium in the ditch.
