Text: we are unable to publish the roost data upon which our paper is based for the following reasons. a very high proportion of the bat roosts are in occupied buildings and records are held by the data centre on condition that the precise locations are not divulged. in addition, the release of the data would compromise the operation of the data centre, which is a not-for-profit charitable conservation foundation that relies on the sale of less precise locations to fund their operations. researchers wishing to access the data can do so by contacting the cumbria biodiversity data centre: www.cbdc.org.uk.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
