Ecostyrocrete bat roosts


In the UK around a quarter of our mammals are from the bat family and there are at least 17 different types of bat known to breed here, along with others who just visit, for now.  

Bats play an important role in many environments around the world. In the UK, some bats are known as ‘indicator species’, because changes to these bat populations can indicate changes in aspects of biodiversity.

UK Bats only eat insects, and a lot of insects at that, around 2000 a night apparently. This makes them important pest controllers for agriculture, not to mention the benefit to us by keeping down the numbers of biting insects.   



Sadly, many bat species around the world are vulnerable or endangered due to factors ranging from loss and fragmentation of habitat, diminished food supply, destruction of roosts, disease and hunting or killing of bats.

In the UK, bat populations have declined considerably over the last century. Bats are still under threat from building and development work that affects roostshabitats, the severing of commuting routes by roads and threats in the home including cat attacks, flypaper and some chemical treatments of building materials. Other potential threats can include wind turbines and street lighting if they are sited on key bat habitats or near roosts.   

 Putting up a bat box is something most of us can do to try to replace natural roosts as we cut down more trees. 






The national charity, the Bat Conservation Trust, have a wealth of information and advice as well as links to how you can be more involved locally by joining a Bat Group and going on evening walks with bat detectors to help with the ongoing monitoring of the conservation status of these legally protected animals.
