Proposed works
- Description of works
- An existing farmhouse hosting a brown long-eared maternity roost to be demolished. A new building was therefore constructed with a loft designed to attract bats to stand for one breeding season alongside the existing habitat prior to demolition.
- Type of impact upon the roost
