- There are over 900 different species of bats in the world equating to around a quarter of all the mammal species.
- They play an important part in the worlds ecosystem with many species acting as pollinators for plants that provide food for the human race such as bananas.
- Bats are one of the few mammals that live in close proximity to people with many species choosing to roost in houses and other buildings.
- Bats are at the top of their food chain and so a healthy bat population indicates a healthy environment
- All UK bats are insect eaters and are therefore an important natural controller of insect populations.
The 18 species of bats found in the UK, 17 of which are known to be breeding. This represents a third of our total mammal species. 13 of these species have been recorded in Suffolk, with three of these being discovered only in the past 30 years.

Five of these species, lesser horseshoe, barbastelle, noctule, brown long eared and 55khz (soprano) pipistrelle, are subject to national Biodiversity Action Plans (BAP's):
There have been widespread declines in the distribution and abundance of bats, particularly during the past 50 years. The reasons for this are complex and can be attributed to a number of causes: the use of pesticides and changes in agricultural practices caused a dramatic reduction in the numbers and variety of insects, affecting food availability; the removal of woodlands and hedgerows has reduced the amount of suitable habitat and the use of toxic chemicals to kill wood-boring insects in buildings caused the deaths of large numbers of bats, with chemicals persisting for many years.
Bats are totally protected under the Wildlife and Countryside Act (1981) (as amended) and The Conservation of Habitats and Species Regulations (2010) (as amended). This legislation not only protects the animals themselves but also their roost sites, even when the bats are not in residence. Any activities likely to change or destroy a bat roost require consent from Natural England. More information on bat legislation can be found here.
