Latin name: Natrix natrix
Grass snakes may be seen basking in sheltered sunny places on mild and sunny days after rain from March or April until the beginning of October. Look out for them in woodland glades or embankments not far from water. They are Britain’s longest snake growing to about 1 metre.
Grass snakes are widespread in England and Wales and absent from some parts of northern England, most of Scotland and Ireland. They are known to be present in the south-east of Yorkshire Dales National Park but are rarely seen. This species is a UK priority species and in 2010 became a priority species for the Yorkshire Dales National Park. The wildlife conservation team of the Yorkshire Dales National Park Authority is working with local volunteers to assist with the National Amphibian and Reptile Recording Scheme (NARRS). This will increase the number of trained local surveyors and surveys and in time should lead to a better understanding of its distribution and status in the Yorkshire Dales National Park.
