Cumberland sliders Trachemys scripta troostii can be found all over the Netherlands, but are the rarest of the three subspecies of Trachemys scripta. Usually only one or a few individual(s) are present at a location. Highest concentrations are present in and around cities, where pet-keepers release these sliders.
Cumberland sliders can survive Dutch winters, but successful reproduction in the wild has not been recorded in the Netherlands. Due to climate change the species might be able to reproduce in the Netherlands around 2050. Because of potential threat to European fauna and flora imports of red-eared sliders Trachemys scripta elegans into the European Union has been forbidden since 1997 by EU-decree 338/97/ec. Pet trade has since then moved on to other subspecies and species, which are now sold in large numbers and sometimes released into the wild. Cumberland sliders make up a small portion of the sliders brought to sanctuaries. In the Dutch risk assessment on invasive exotic turtles the species is listed as ‘Substantial risk’.
