Dr Martin Warren, CEO of Butterfly Conservation, will be walking a 100 mile stretch of coastline in just seven days to raise funds to save threatened butterflies.
The Jurassic Coast, straddling Devon and Dorset, is a world heritage site rich in fossils, but it is also rich in butterflies and boasts some of our rarest species including the Wood White, Lulworth Skipper and Adonis Blue.
Dr Warren’s hike starts on Monday 27 July at Orcombe Point, Exmouth, Devon and finishes on Sunday 2 August in Swanage, Dorset.
All funds raised will go towards Butterfly Conservation projects to save vulnerable colonies of Wood White, Duke of Burgundy and High Brown Fritillary.

The hike falls during the Big Butterfly Count and Martin will be attempting to complete a record breaking 150 Counts while he walks.
