Well some populations of Persian Fallow Deer used to be in Turkey and they were once introduced to some areas of Greece or something like that. I don't know my sources, but I could be wrong. I was just going under the impression of "close enough" and its a subspecies of the Fallow Deer which is a European/ Mediterranean animal.
Anyways, since we're talking about European animals and about rarity and all. I found an interesting article about European reptiles and amphibians from the IUCN site: IUCN - Europe?s amphibians and reptiles under threat - IUCN
