The results of a 24 year survey of a community of reptiles typical of northern Europe along a 19 km long railway track in the South of Belgium suggests that: i) four among the six species (Anguis fragilis, Podarcis muralis, Zootoca vivipara, and Natrix natrix helvetica) exhibited stable abundance levels and distribution patterns; ii) Vipera berus strongly decreased and is now nearly extinct; iii) Coronella austriaca appeared in the course of the survey and its populations sharply increased. The decrease of Vipera berus can be explained by the degradation of some of its habitats. The causes of the increase of Coronella austriaca are unknown but might be linked to climate change.
