Leith Athletic clubhouse re-development
To determine the potential of Leith athletic club-house to support a bat roost Practecology undertook a bat assessment.
As bats are protected by both UK and European Law it is important to determine whether they are present in buildings before any construction work or demolition is undertaken. This is to allow time for a suitable bat mitigation plan to be devised and all relevant licences to be obtained from the statutory body.
Internal and external assessments for bats
To determine the likelihood of bats occupying a structure an initial investigation was carried out on the external surfaces of the building. This was primarily to detect possible points of entry (e.g. missing slates, gaps under eaves and soffit boxes or missing mortar) but also to see if there are any signs of bats occupying the immediate landscape such as bat droppings on window sills and walls or occasionally feeding remains. On completion of the external survey, access was gained into the structures attic to look for bats and their signs. Droppings, feeding remains, urine staining can all be used to confirm the presence of a roost, but of course the presence of bats themselves is the most obvious indicator!
In addition to day time assessments, it is also necessary to carry out bat activity surveys at dusk and dawn to determine whether bats are gaining entry to the building and using it as a roost. Such surveys are also ideal at identifying roost access points, they enable bats to be counted and species identified, and provide invaluable information needed as part of a protected species licence application to allow the works to proceed.
