Wind farm causes concern for Lundy seabird recovery
Ten years ago a project began to eradicate rats from Lundy, the largest island in the Bristol Channel, UK.
The rats had been blamed for a serious decline in the numbers of nesting seabirds and puffins - which the island is famous for - were reduced to just a few individuals.
Since the island has been declared rat free, numbers of seabirds have boomed, with Manx shearwater numbers rising from 300 to 3,000 breeding pairs.
In this clip, Jez Toogood looks at their progress and discovers plans for an offshore wind farm are causing new concerns for Lundy's seabirds.
