The earliest photograph of red-eared slider

Alien species are species living outside of its native distributional range. They have arrived there by human activity, either deliberate or accidental. As they make a strong imapact on their new habitat and species living there, it is believed they cause damage to the environment and may cause extinction of native species.


In the 1970s the red-eared slider, Trachemys scripta elegans arrived in Croatia for pet trade purposes.Many of them were released in the wild but no exact data upon their first release are provided. First documented findings of this terrapin in the wild are available from later 1990s.
This is why Croatian herpetological society – Hyla is kindly asking of you to search through your old photo albums, postcards, photographic film and other media and send us your records of red-eared sliders in Croatia. (Red-eared sliders are most commonly found in urban fresh water habitats, such as Maksimir Park in city of Zagreb). Your data will be used in scientific analysis to determine when this species started to spread in the wild and in what magnitude does it endanger our native species - European pond turtle, Emys orbicularis. You can e-mail us your records at This email address is being protected from spambots. You need JavaScript enabled to view it. and we will award you with a CHS – Hyla T-shirt of your choice!
