Alien Organisms and trade in Endangered Species (CITES)

Will assess the risk on biodiversity from import and keeping of snails

Report no:

Ordered:

Published: 15.12.2017

Main message:

The Norwegian Scientific Committee for Food Safety will assess the risk to Norwegian biodiversity stemming from import and keeping of terrestrial snails in terrariums.

The Norwegian Environment Agency will use this risk assessment as a basis for processing applications regarding importation and private keeping of terrestrial snails. This comes as a result of the agency receiving several requests regarding this, following the entry into force of the Regulations relating to alien organisms under the Norwegian Nature Diversity Act, on January 1st 2016. Om oppdraget

The Norwegian Environment Agency requests the Norwegian Scientific Committee for Food Safety to:

  1. Determine which species of terrestrial gastropods that are available for trade and relevant for private ‒ hobby based ­­‒ keeping in Norway.
  2. Assess the biotic and ecological properties (e.g. habitat, diet, behavior) and abiotic tolerance limits (e., in relation to humidity, pH and temperature) of terrestrial gastropod species that would dictate whether the species may or may not survive in the Norwegian habitat if released or escapes.
  3. Assess the biotic and ecological properties (e.g.habitat, diet,behaviour) of terrestrial gastropod species, which would indicate whether they would have any negative impact on biodiversity, including the spread of pathogens, if such information is available.
  4. Undertake an assessment of the risks of negative impacts on biodiversity in Norway stemming from the import and keeping of the terrestrial gastropods identified under part I of these terms. The risk assessment should be based on the biotic and abiotic properties emerging from part II and III of these terms.
  5. Provide a summary of which properties of terrestrial gastropods that emerged from the risk assessment (part IV) as most relevant for determining whether a species could have negative impact on biodiversity. Additionally, a qualitative analysis of the available literature for these properties should be provided. Also, if thereisspecific differences in the requirement for information between taxon (e., between different genus within the same family), this should be included in the report.

The Panel on Alien Organisms and Trade in Endangered Species will be responsible for conducting the risk assessment.
