Trachemys scripta (Thunberg in Schoepff, 1792) is a species of common, medium-sized, semi-aquatic turtle. It has been listed as one of the “Top 100” World’s Worst Invaders. These turtles often fight with native species for food, habitat, and other resources. Eventually they bully many native species out of basking sites – areas where there is sunlight and warmth for the species. When basking it is common that pond sliders will do so on birds’ nests, thereby killing the eggs. They also prey on young birds. Turtles that were raised in captivity can develop diseases that are unfamiliar to native species, which can be harmful. Turtles raised in captivity are often released because they become too much to handle or grow bigger than expected. It’s not uncommon that pond sliders will also run away (Wikipedia contributors 2020).
IAS of Union concern
In 2016, Trachemys scripta (Thunberg in Schoepff, 1792) was added to the list of invasive alien species of Union concern (Anonymous 2016) which implies that member states shall take all necessary steps to prevent its unintentional introduction or spread.
Status and distribution in Luxembourg
Currently, 173 records in Luxembourg are accessible through the MNHNL-mdata portal, when combining the species (145) with its two subspecies, T. scripta scripta (11) and T. scripta elegans (17) present in Luxembourg (MNHNL, iNaturalist & GBIF 2020).
Invasive pond sliders have been observed climbing the platforms of waterbirds, especially great crested grebes (Podiceps cristatus), to sunbathe, thus preventing successful breeding (Konter 2020: 81).
More details are available on the pages dedicated to both subspecies (see their distribution maps below).
See the subspecies pages for further details.
Other Trachemys taxa
The pond slider Trachemys scripta (Thunberg in Schoepff, 1792) has three subspecies (Wikipedia contributors 2020b), of which the first two occur in Luxembourg:
- Trachemys scripta scripta (Thunberg in Schoepff, 1792), the yellow-bellied slider;
- Trachemys scripta elegans (Wied-Neuwied, 1839), the red-eared slider;
- Trachemys scripta troostii (Holbrook, 1836), the Cumberland slider. According to GBIF (2019b) this subspecies is already present in Europe (Belgium, The Netherlands, Germany, Poland and Spain).
