Yesterday a paper was published in Scientific Reports – one of the journals of the prestigious Nature brand which revealed a new species of grass snake in Europe. You can read the original paper here: Carolin Kindler et al. Hybridization patterns in two contact zones of grass snakes reveal a new Central European snake species, Scientific Reports (2017). DOI: 10.1038/s41598-017-07847-9. (free download – it’s an open access paper).
The sub-species of grass snake Natrix natrix helvetica therefore became a species in its own right Natrix helvetica. So far so good.
The media then made the jump – therefore there is a new species of grass snake in Britain bringing our snake fauna up to 4 species i.e. two species of grass snake, smooth snake and adder – wrong!
The grass snake found in the UK is Natrix natrix helvetica and so our existing species of grass snake now becomes Natrix helvetica – there are no Natrix natrix grass snakes in Britain now so the snake count remains at 3.
What a glorious cock-up!
Were it not for this rather underplayed Tweet from Barry Kemp (a reptile expert) I would have carried on in my unbridled euphoria.
