Battle to save rare high brown fritillary butterfly

15 September 2013 Last updated at 01:41 BST

Inside Out looks at efforts to save one of the country's rarest and most threatened butterflies, the high brown fritillary.

Since the 1970s national numbers of the butterfly have declined by 90% with the destruction of its traditional moor and woodland edge habitat.

In Devon, one of the high brown fritillary's few remaining strongholds, there are now thought to be only a handful of breeding sites left.

Devon Wildlife Trust is making huge efforts to save the butterfly through habitat management and conservation work.

Nick Baker travels to the River Dart in Devon in search of the elusive high brown fritillary and talks to a conservation expert about its long term chances of survival.

Inside Out is broadcast on BBC One South West at 19:30 BST on Monday, 16 September and nationwide on the iPlayer for seven days thereafter.
