An Aesculapian snake. Creative Commons. Britain has a new, or perhaps old, snake species, raising questions about the purpose of conservation. There were just three species of snake in the UK, but accidental releases of the nonvenomous Aesculapian snake, including into a London canal, have created thriving populations. Some conservationists argue they are an invasive species, although they lived in Britain 300,000 years ago. But two academics wrote in The Conversation that Aesculapians are struggling in their southern European heartlands, and while conservationists “normally focus on preserving species within their modern ranges,” climate change makes that increasingly untenable. It would be “tragic” if the species went extinct elsewhere while being “treated as undesirable aliens” and evicted from its new home. |
