Conservationist Sacha Dench on tracking swans 7,000km across 11 countries

When she dropped out of the sky in front of Russian hunters in the Arctic, Sasha Dench wasn't quite sure how she'd be received. She was on a mission to understand and halt the decline in the numbers of the Bewick Swan by following their epic migration route from the Arctic to the UK on a paramotor.

Join her on a walk from her favourite training field down through some woods to Fernworthy reservoir on a typically wet and wild Dartmoor day.
