Bat Surveys for Quarry Expansion
Tarmac Western
Keystone Ecology carried out preliminary internal/external bat surveys of buildings scheduled for demolition to make way for quarry expansion.
Having found evidence of bat activity we then carried out emergence surveys to determine roost status and provide sufficient information for a European Protected Species licence application. Once the licence was successfully determined we conducted pre- demolition surveys and erected bat boxes on trees scheduled for retention.
