Keywords:Pond Slider, Trachemys scripta, invasive species, turtle, citizen science, pet trade
The Pond Slider (Trachemys scripta) is a turtle native to the eastern United States, but, because of its popularity in the pet trade, it now occurs in many countries around the world as a result of escapes and the release of unwanted pets. The distribution of the Pond Slider in Ontario is reviewed based on 393 records obtained from various sources. Sliders have been reported from 130 spatially distinct sites in 35 districts. The Toronto area accounts for 67% of records, and more than 80% of reports are from urban areas. Pond Slider reports date back to the 1950s, but 63% of records are from 2010 or later. Sliders have been observed in Ontario during all months of the year except December. Sliders have bred in Ontario, but the spatial extent of successful reproduction remains unknown.
