A moorland fire may have destroyed over 300 breeding pairs of rare birds, said wildlife experts.
Last month, firefighters in Lancashire tackled a blaze on Darwen Moor that burned over 5km (3 miles) of moorland.
The area is a designated breeding site for ground-nesting birds such as the skylark and curlew who have been hit badly, said Lancashire Wildlife Trust.
Fire crews believe the the fire on 30 May was started by a disposable barbecue found nearby.
