| Abstract | The reptile fauna of the siliceous rock habitats of the central-eastern Ardenne was studied between 2000 and 2007. The investigations were carried out at 26 sites distributed in all the hydrographic watersheds draining the area, except one (the Our watershed): Eastern and Western Ourthes, Ambleve and Sure. All the significant rocky habitats of the area were studied: rocks and landslides, abandoned quarries and exploitation dumps, rail and road embankments. Five species were recorded: Anguis fragilis, Podarcis muralis, Zootoca vivipara, Coronella austriaca and Natrix natrix, of which Anguis fragilis and Zootoca vivipara were the most widespread. Podarcis muralis was only found in the Ourthe basin. The population of the latter species at Herou constitutes a remarkable isolate while the population along the Stoumont-Coo railway is one of the largest in numbers in the Benelux countries. Coronella austriaca is reported for the second time in the Western Ourthe valley. This snake is only present in the most thermophilous habitats, where the majority of the populations seemed extremely isolated. Natrix natrix was rather widespread but never abundant. |
