Bats on the brink: A search for the grey long-eared bat

One of the UK's rarest mammals, the grey long-eared bat, is in danger of disappearing from the country, according to research.

A four-year study by scientists from the University of Bristol estimated that there were just 1,000 of the bats left - all confined to southern England.

BBC science reporter Victoria Gill went in search of the bats at a secret location in Devon - one of just ten known maternal roosts.

Dr Orly Razgour, who led the research and was the guide on this bat safari, says the bats' foraging habitat needs to be protected if the species is to survive in this country.

The Bat Conservation Trust has published the findings in a new conservation management plan.
