Die Geschichte der Historie der Stuttgarter Westlichen Smaragdeidechsen, Lacerta b. bilineata Daudin, 1802.

A witness reports the release of 100 Western Green Lizards Lacerta bilineata, originating from the canton of Ticino, Switzerland in the early 1950ies. The place of release is a residence area with garden-surrounded houses at Hasenberg Mountain within the city limits of Stuttgart, Germany. A permanent population established itself, remained undetected until 1996 and is meanwhile observed by the public. The area was formerly inhabited by Sand Lizards Lacerta agilis who vanished ca. 1970. The present accompanying reptile fauna consists of Slow Worms Anguis fragilis and Smooth Snakes Coronella austriaca. Since 2017 Common Wall Lizards are observed, phenotypically assigned to Podarcis muralis maculiventris of the Southern Alps lineage. [ABSTRACT FROM AUTHOR]
