Research of herpetofauna on the Krk island under the LOKNA project

LOKNA project is approved under the Operative programme of territorial cooperation Slovenia-Croatia 2007.-2013., with the Public Institution "Priroda" as the leading partner. This project was mostly financed by the EU - European Regional Development Fund. The main goal of the project is to preserve and revitalize water biotopes (pools on Krk island and barjanska okna in the Ljubljana marshes) through joint cross-border approach of evaluation, inventarisation, revitalization and promotion of water biotopes. You can see one example of such revitalisation on this link: Revitalization_in croatian

Realization of the activities of the project begun in February of 2015, and the of project is planned to end in May of 2016. The main activities in Croatia are conducted on the Krk island, where the listing of 60 pools is taking place along with scientific researches on three selected pools (dragonflies, plants, bats, herpetofauna and birds), making an educational trail about karst pools and photo exhibition, educational workshop and the final conference about the project, all of which is done with the help and cooperation of partners and associates. The joint GIS data base of water biotopes and web page of the project will also be made. The important segment of the project is printing multilanguage educational and promotional materials –  flyers, posters and brochures. They contribute to the recognition of the project and raising of awareness and educating locals and tourists. A short notice about some of the researched groups of animals is here: Researched animal_in croatian

CHS-Hyla participated in this project as an associate with the goal of listing the species of herpetofauna on three pools on Krk island: Omatine pool, pool near the small oak and pool near Poljice, together with their terrestrial habitats. On these three locations five species of amphibians and reptiles have been found. One of them is the marsh frog (Pelophylax ridibundus) which was the most abundant (Figure 1).

The yellow-bellied slider (Trachemys scripta scripta) was also found during this research. This is a native species in the USA. These turtles are used as pets in Croatia. They are found in the nature habitats because people throw them out when they don't want to take care of them anymore. This species is very well adjusted to our climate and they are in competition with our native species (for example European pond turtle, Emys orbicularis), especially in feeding and basking. This is why this species is an invasive species in Croatia.
