Invasive neophytes
Neophytes are foreign plants that were introduced after the discovery of America by Columbus in 1492, either intentionally as ornamental or fodder plants or unintentionally through global trade and transport. Some species spread very rapidly and displace the native flora, such as Japanese knotweed or balsam. They are therefore referred to as invasive species. Some of these invasive species, such as giant hogweed and mugwort ambrosia, also pose a risk to human health. In the city's protected areas, invasive neophytes are combated in all known locations. The suppression, reduction or removal of invasive neophyte populations is desirable everywhere in the wild, but unfortunately the general spread of many species can no longer be stopped. In the city of Chemnitz, efforts are being made to at least prevent the spread of giant hogweed and mugwort ambrosia due to the risk to human health. All residents are called upon to report any locations where they have been found to the environmental office, the public order office (citizens' telephone) or the city of Chemnitz authorities' telephone number!
