NNF organizes an exhibition on invasives species !


Today, the communication media we are used to (newspapers, TV) hardly inform general public about invasive species. Information can be wrong or contradictory, and sensationnalism is often favoured.

There is therefore a real need for a communication medium so that, on the one hand, the advances of knowledge based on scientific data can be presented, and on the other hand, the development of practices thanks to experience-sharing can be favoured.

That is why our organization presents an exhibition on invasive species.

Object of the exhibition:

Invasive species

  • How are they introduced?
  • How do they develop?
  • What impact do they have on biodiversity and people?
  • What means are implemented to fight them?
  • What are the challenges to come?

Aims of the exhibition

  • clearly exposing the issue, while relying on a scientific basis
  • illustrating by well-known examples
  • raising awareness, without sounding alarming
  • contributing to the modification of the practices which lead to the introduction of invasive exotic species in natural habitats.

Why these countries?


In Switzerland the issue of invasive exotic species is as problematic as in the rest of Europe and in many other countries of Central Europe. A report from the Federal Office for the Environment published in 2006 numbered about 107 invasive alien species.

Some species, for instance the Eastern grey squirrel (Sciurus carolinensis Gmelin) which is a great issue in Italy, haven’t colonized Switzerland yet, but it may cross the border anytime soon. The National data and information center on swiss flora recently published a list of species (august 2014), which classifies the species into a black list (40 taxa) and a « Watch List” (17 taxa or groups of taxa). Knowledge is improving, control is organized… Nevertheless public information and sensibilisation still need improvement.


United Arab Emirates

Natural habitats in the arabic peninsula, where the United Arab Emirates are located, are mainly from semi-desertic to desertic. Despite the seeming poorness of the environment, these habitats are inhabited by unique and remarkable species.

On the face of it, in comparison with other countries, the issue of invasive species seems to spare the UAE, because of the low number of species living on this territory. Only 25 species are indexed in the international database of invasive alien species (www.issg.org). Nevertheless these unique ecosystems are more and more artificialised : natural habitats are reduced in favour of farming and alien species are introduced.

The introduction of alien fauna and flora can have a big impact. Raising awareness about the risks of introducing invasive alien species and creating means to control the arrival of persons and goods is essential. Public information will support any measure taken for this purpose.

The United States of America

This enormous country presents a large variety of climates and environments, each of them with their singularities. But today, many species, whose introduction was authorized and even encouraged by the government until the beginning of the XXth century, are a threat for this diversity. North America indeed numbered up to 200 invasive species. The Great Lakes and the Rocky Mountain Region are the more threatened regions.  Coastal regions, such as California and Florida, and Hawaii Island, are also widely endangered.

Moreover, the United States being the second biggest polluter in the world, ecosystems are more and more fragilized.

In a country which is more and more aware of ecological issues, it is important to implement everything we can to enforce awareness and increase knowledge.
