Martin Crawford is a British author who is the founder and director of the Agroforestry Research Trust. He runs regular tours of the 2-acre forest garden at Dartington in Devon as well as the Littlehempston site as well as courses in the design of Forest Gardens. In March 2025 Crawford was given notice to vacate the forest garden at Dartington Estate which led to more than 18,000 people signing a petition to oppose the move.
