“The island in the Bristol Channel is home to 95% of England’s breeding Manx Shearwaters, a species that was once on the brink of extinction on Lundy.
Thanks to a project that eradicated rats from the island in 2006, the Shearwater population has soared from about 600 in 2001 to more than 25,000. Puffins have increased in number from 13 in the year 2000 to 1,335 in 2023.
The island has also attracted new arrivals, such as Storm Petrels, which first bred on Lundy in 2014 and now have more than 150 pairs.”
