Origin and Worldwide Distribution:
  • It was introduced into Europe as a pet in the 1960s. Since then, individuals have most probably escaped or been deliberately released from captivity.
  • So far, isolated wild populations have been recorded in woodlands, suburban forests and urban parks in Belgium, France, Germany, Ireland, Italy and the Netherlands.

Potential or Known Impacts:
  • It is suspected to compete with native rodents and may have a local impact on ground-nesting birds, although the numbers of studies investigating its potential impact on biodiversity are currently limited.
  • It can also cause significant damage to crops, gardens and orchards and it is a potential host for various infectious diseases, such as Lyme disease or rabies, and parasites.

How could it get here?
  • The Siberian chipmunk was a popular as a pet, and some individuals escaped or were released intentionally from captivity.

Is it found in Northern Ireland?
  • It has not been recorded in Northern Ireland.
  • More distribution information can be found at NBN Atlas NI.

Methods for Prevention:
  • A sales ban, the phasing out from zoos, collections and any other ownership, a rapid eradication of any newly emerging populations and the management of established populations should prevent the species from becoming a wider problem.
  • Report all sightings.

You can help by reporting any sightings: @ the Centre for Environmental Data & Recording (CEDaR) - Or via the iRecord App.
