Grass snakes in Britain were thought to belong to the subspecies N. n. helvetica but have been reclassified as the barred grass snake Natrix helvetica. Any records of N. natrix in Britain are now considered to have originated from imported specimens.
Jul 6, 2019 · Until recently the barred grass snake (Natrix helvetica) was classified as a subspecies of the more wider-ranging European grass snake (Natrix natrix). This was until in 2017, after some investigation into the mitochondrial DNA of different populations of grass snakes across Europe, that N. natrix was split into a handful of species.
The Italian barred grass snake (Natrix helvetica sicula) is a fascinating subspecies of grass snake, known for its striking appearance and crucial role in the ecosystems it inhabits. This article dives deep into the lives of these remarkable reptiles, exploring their behavior, habitat, and the vital contributions they make to their environment.
Most of Switzerland is inhabited by the nominotypical subspecies of the barred grass snake (Natrix helvetica helvetica), which is characterized by mitochondrial DNA lineage E. Only in the northeast of the country, the common grass snake (N. natrix) occurs and hybridizes with N. h. helvetica in a narrow contact zone.
