Neophytes as a threat to humans and the environment

There will be a neophyte exhibition on the Alpenquai in Zug from 15 to 21 May. The aim is to sensitise the population of Zug to the problem of invasive plant species.

The term ‘neophyte’ is used to describe alien plants that have been introduced to Europe by humans, either consciously or unconsciously, after the year 1500. Most of these species are inconspicuous and unproblematic. But some of these invaders reproduce uncontrollably and are highly invasive. These invasive neophytes can cause ecological damage, such as the displacement of native species. Loss of agricultural yields and damage to buildings and infrastructure are also possible.

One example is the giant hogweed (Riesenbärenklau). In combination with sunlight, its sap causes painful and severe burns if it comes into contact with the skin. Another example is Henry's honeysuckle (Henrys Geissblatt), which hinders the growth of young trees in the forest.

The city of Zug is actively combating the spread of invasive neophytes on public land and is fighting their further spread. But exotic plants also grow in many private gardens, and the city wants to draw the public's attention to the problem with an exhibition on Alpenquai in Zug from 15 to 21 May.

As the City of Zug writes, some of the most important neophytes will be exhibited and described in detail in 12 lattice baskets. A team of experts will also be on site from 6 p.m. to 7.30 p.m. on Tuesday, 16 May, to present the species and point out the dangers they pose to humans, the environment and animals. It will also be explained why the neophytes are a problem and what you can do against the exotic plants in your own garden.

Proper disposal of neophytes is particularly important. That is why the cantons of Central Switzerland have jointly launched the "neophyte bag". This is available free of charge in the town of Zug at the Ökihof at Industriestrasse 80/82, at the town hall at Gubelstrasse 22 and at the Werkhof (Municipal services depot) at Göblistrasse 7 in Zug. The filled bag can be returned to the Ökihof free of charge.
