A Cornish conservation charity has launched an ambitious rewilding project intended to benefit creatures from marsh fritillary butterflies living high on the moor to long-snouted seahorses in seagrass in a bay five miles away.

The Tor to Shore project will stretch from Helman Tor, a reserve topped with a granite boulder summit near Bodmin, to St Austell Bay via the tumbling River Par, its idea to improve a landscape at scale.

The National Lottery Heritage Fund has awarded the Cornwall Wildlife Trust a £265,000 development grant for the project, and if it goes to plan another £3m should follow.
