As you may have read in our previous blog post on our website, we found a grey long-eared bat in a roost in East Devon and confirmed the species with DNA analysis. We are pleased that yet another record, some miles away, has been found.

There are thought to be only between 1000 – 3000 grey long-eared bats in the UK. This species is rarely recorded, giving it a very rough population estimate. There is little data about their range, but records show that they are confined to coastal areas in the extreme south of the UK, with a couple of records from South Wales.

Conducting DNA analysis of droppings at long-eared bat roosts is important for discovering more about this rare species. Grey long-eared bats (Plecotus austriacus) and brown long-eared bats (Plecotus auritus) are very similar in many ways and can be difficult to distinguish from one another under normal survey conditions.
