Yorkshire Dales Adders Join National Health Check

A significant national project is underway to assess the health of adder populations across England, with the Yorkshire Dales playing a key role. The Nidderdale National Landscape, a protected area, is at the forefront of this Natural England initiative, focusing on vital DNA analysis. Scientists have observed a concerning decline in adder numbers nationwide, underscoring the importance of this conservation research.

Nidderdale was selected for this extensive study due to its well-established monitoring systems and abundant semi-natural habitats, which provide an ideal environment for research. Dr. Kelly Harmar from the Nidderdale National Landscape highlighted the area's potential significance, stating that surveys over several years suggest it may be nationally important for reptiles.
