Pine martens return to Dartmoor after 150-year absence

Fifteen of the nimble, tree-climbing mammals were released last month at secret locations in Devon

Fifteen pine martens are darting through the woods of Dartmoor for the first time in 150 years after the rare but recovering species was reintroduced into south-west England.

The nimble, tree-climbing mustelids were released last month at secret locations in the steep, tree-lined valleys of Devon in what conservationists are hailing as a historic step in the restoration of the region's woodlands.
