|
The distribution of the Balkan Pond Turtle in the Aegean region is presented by means of the author's observations and information from references, including a comparison of historical records and current data. Within its vast range across southeast Europe and western Asia Minor, a considerable local decline of this turtle's populations, chiefly due to the loss of wetland habitats, was observed over the last decades. Mauremys rivulata (VALENCIENNES, 1833). is a species of reptile whose distribution does not correspond to the geological graben system, i.e. it is to be found throughout the Aegean archipelago. To date, the species' occurrence is known from 29 Greek and two Turkish islands. In this paper. the turtle's present situation on Kea (Cyclades) is used as an example to discuss the distribution and ecological requirements of M. rivulata and the threats to its survival. Its preferred habitats are to be found in the estuaries of streams and rivers, which are threatened by increasingly intensified forms of use (e.g. tourism, construction, intensive agriculture). According to an inventory drawn up by WWF Greece, wetland structures on Aegean islands tend to be small in scale. That makes them all the more vulnerable to damage and destruction. Rcfugial, populations of the Balkan Terrapin are to be found along some of the middle and upper reaches of streams and rivers on the biggest islands, but normally these populations are small. In the interior of the islands, more and more reservoirs are being built, which can be colonized by the Balkan Terrapin. The Greek islands arc in urgent need of a targeted nature protection strategy to ensure preservation of their natural assets, the last remaining wetlands in particular. They are so important to the hygrophilic herpetofauna and other specialized species of the flora and fauna, e.g. as stepping stones for migratory species. and current data.
