Abstract
The German North Frisian Islands are naturally void of snakes. Although there were rumors decades ago that the adder Vipera berus (Linnaeus, 1758) occurs on these islands, there was no evidence of its presence on any of the islands. In this study the first verified record of V. berus on Sylt, the largest of these islands, is documented. This is also the northernmost record of V. berus for Germany.
