Finland:

Bombina variegata. Breeding. Just heard about this a few days ago.
Lacerta agilis. Breeding.
Pelophylax lessonae*. Breeding and spreading.
Pelophylax ridibundus*. Breeding and spreading.
Ichthyosaura alpestris. Breeding. Significant potential for spreading.
Hyla sp. Can't remember whether meridionalis or arborea. Apparently not breeding, but overwinters in someone's garden.

Most of the species are found in a narrow region in the south-west, which is a bit dodgy. All species are very likely deliberate releases, but accidental introduction of some species is possible as there are a lot of plant-importing greenhouse-farmers down there.

* The origin of the Pelophylax sp. is being worked on. Also, the species IDs aren't all clear.

That's a big bunch of introduced species for a country with 10 indigenous herp species.

Whom it might interest after such a Long time...

The capture of a juvenile red-eared slider (Trachemys scripta elegans) at the Altrhein in
Kehl (Baden-Württemberg) 2005 was taken for the occasion to discuss the situation of this
turtle subspecies in Baden-Württemberg by Hubert and myself. The living conditions of the red-eared
slider in its natural distribution area are shortly reported, and opposed to observations
at released specimen in Baden-Württemberg. We assumed that the juvenile turtle
resulted from a successful natural reproduction of a released or escaped female, and
that the turtle had already survived its first winter in nature or in its nest hole.
Sincerely yours,
Alex

Known from two locations. One can hardly say that the species is spreading.

Ridibundus has not been identified for certain in Finland since 1960.
Esculentus is found on many sites and seems to be spreading.

There is really no much doubt about the species IDs. Esculentus is known for certain from 5 locations and lessonae from 2 locations. In most cases it has been very easy to tell the species.

Also, I am not sure about the Hyla. I am aware of at least one case in Finland where Pelophylax has been misidentified as Hyla.

(although the Orthriophis case is build on the find of a single juvenile = could be escape still...).
3 juveniles and 8 adults in 2015.

and at least 2 or 3 of Natrix natrix. Also plenty of other terrapins and a Xenopus at one point. The list of escaped pets found is endless.[/quote]

new discovered?
P. muralis: there are very old records from Novo Alexandria = Pulawy and Trzebinia. At least the second location is very close to the new discovery.
N. tessellata: The old record (but not 100% sure) is from Ludynia.
For both see:
Fejervary, G.J. (1923): Über die von Dr. A. Pongrácz in Polen gesammelten Amphibien und Reptilien.- Archiv f. Naturgeschichte 89A(4): 1 - 35

It should have been "newly rediscovered". Sorry.

Michal,

it was not your fault.
The problem is/was, none of the authors of the two herpetology-notes papers knew the Fejervary paper

Natrix tessellata

Our report brings the first written information about the discovery of an isolated but stable and reproductive population of N. tessellata near the town of Havířov (Czech Republic, Silesia, 49°47’N, 18°2 5’E, 252 m a.s.l.), and about the marginal occurrence of this species in Poland.

Podarcis muralis

Pax (1925) mentioned that a few individuals of Podarcis muralis have been released into the wild in Silesia (SW Poland). However, this species was not recorded in Poland (Berger, Jaskowska and Młynarski, 1969; Juszczyk, 1987; Berger, 2000; Głowaciński and Rafiński, 2003).
