Invasive neophytes
Invasive neophytes are exotic weeds that spread and multiply rapidly. They can cause environmental, health-related and economic harm by:
displacing native species and restricting biological diversity (Canada goldenrod, Himalayan balsam, Japanese knotweed, annual fleabane, buddleja)
causing skin burns, allergies and poisoning (giant hogweed, ragweed, narrow-leaved ragwort)
contributing to soil erosion, especially on riverbanks and embankments (Himalayan balsam, Japanese knotweed), destabilising buildings and infrastructure such as bridges (Japanese knotweed)
A number of invasive neophytes are found in the UNESCO Biosphere Entlebuch, especially around rivers – in the wake of flooding, bare patches of land can be formed where tiny plant particles will settle and begin to spread. For example, Japanese knotweed is spreading on the nationally important floodplain of the «Ämmenmatt» alongside the Kleine Emme.
The UNESCO Biosphere Entlebuch coordinates, oversees and finances measures aimed at countering invasive neophytes, which are displacing native flora in sensitive zones. We are also committed to coordinating countermeasures in the various communities and staging training events in regional schools, garden centres, etc. while raising awareness among the general public (for example, through newspaper articles and information stands).
