Conservation efforts have taken an important step forward, thanks to observations of bats – creatures that make up a quarter of all of the UK's native mammal species.
In a paper published today, researchers at the University of Leeds describe how they recorded the echolocation calls of more than 15,000 bats during 120 walks in the Lake District to create maps that show the suitability of areas for bat habitation.
They are the most detailed large-scale habitat suitability maps ever created for bats in the UK, with a resolution of 50 metres.
