A continental-type of pipistrelle was found during the study

Twelve roosts of bats have been saved as a direct result of work done by Jersey's Environmental Services Unit.

Research ecologist Dr Louise Magris has spent two years studying Jersey's bat population.

Her survey has found two new varieties not previously thought to live in the island; a continental-type of pipistrelle and the brown long-eared bat.

Bats and their homes are protected under wildlife laws because they are an endangered species.

Dr Magris says the new information will be used when planning applications are considered to make sure roosts are not destroyed by building work.

She says she is hopeful Jersey's bat population now has a more positive future.
