Origin and Worldwide Distribution:
  • The slider is native to Eastern and Central US.
  • In the past, over 50 million individuals have been imported into Europe for the pet trade. Many have since escaped or been deliberately released into the wild.
  • The species is now present in Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Luxembourg, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, and the United Kingdom.

Potential or Known Impacts:
  • The slider is a serious threat to endangered populations of indigenous turtle species, such as the European pond turtle (Emys orbicularis) or the Mediterranean turtle (Mauremys leprosa) because it competes for basking and nesting sites. With its voracious appetite, it disturbs aquatic habitats and poses a human health risk, being a possible reservoir for salmonella.

How did it/could it get here?
  • In the past, over 50 million individuals have been imported into Europe for the pet trade. Many have since escaped or been deliberately released into the wild.

Are they found in Ireland or Northern Ireland?

Methods for Prevention:
  • The import of the red-eared, yellow-bellied and Cumberland sliders has already been banned through the EU Wildlife Trade Regulation, but placing all three sub-species on the Union list will further contain the invasion.

  • Record all sightings on CEDaR

Current Legislative Position (Listed on 03 August 2016)
