The European Network on Invasive Alien Species (NOBANIS) is a gateway to information on alien and invasive species in North and Central Europe.

Regional portal on invasive alien species

NOBANIS covers marine, freshwater and terrestrial environments and provides: 

  • A distributed but integrated database on introduced species in the region
  • Fact sheets on many of the most invasive aliens
  • A catalogue of the regulation relevant to invasive species in participating countries
  • A photo bank of alien species
  • A marine key to identify invasive species in Nordic waters
  • A catalogue of regional databases
  • Connections to regional and global networks and projects of invasive aliens species

Stop Arctic Aliens

Are you travelling alone? Have you checked your baggage for alien species?Polar Bear welcoming

An animated film intended to inform travellers about the dangers that alien species present to Arctic ecosystems is being released today. The message is that it is important to ensure that nobody accidentally brings alien species with them as stowaways in their clothing, baggage or equipment.

We still have a window of opportunity to protect the Arctic from the impact of alien species. The most effective action  is to prevent the introduction of potentially harmful alien species. Contributing to this goal is everybody’s responsibility. Luckily there are some simple measures that you can take!

Brush! Hoover! and Wash!

The film project is a response to the ARIAS Arctic Alien Species Strategy and is led by the Norwegian Institute for Nature Research (NINA), in cooperation with the Swedish Environmental Protection Agency and the Ministry of Agriculture and Forestry of Finland. In addition, important collaborators are the Governor of Svalbard, the Norwegian Environment Agency, Association of Arctic Expedition Cruise Operators (AECO), Visit Svalbard and Hurtigruten Svalbard

Arctic Alien Invasive Species Strategy on the way to implementation

Work with implementing the Arctic Invasive Alien Species Strategy (ARIAS), adopted by the Arctic Council in 2017, continues within a circumpolar woking group under the auspices of Conservation of Arctic Flora and Fauna (CAFF) and Protection of the Arctic Marine Environment (PAME) groups.


The ARIAS strategy recommends strategic priority actions that need to be taken to protect the Arctic environment from invasive alien species. At present the Arctic is relatively unaffected by negative impacts of invasive alien species, but with changes in the climate, opening of new sea routes and increased exploitation of natural resources, risks for introduction of invasive alien species will rapidly increase.
