This episode of The Green Interview features Diana Beresford-Kroeger, a unique blend of rigorous scientist, reverential philosopher, and Irish bard who profoundly understands the intertwined life of a forest. Beresford-Kroeger, raised in Ireland, now lives with her husband on a 160-acre farm and forest in Merrickville, Ontario where she has planted and observed, more than 6,000 species and varieties of flowers, shrubs and trees, including varieties she has bred specifically to survive in a changing northern climate. She is passionate about the preservation of rare and near-extinct plants and the medicines they provide, and strongly advocates the use of "bioplans," aimed at re-foresting cities and rural areas with trees that provide medicinal, environmental and nutritional "eco-functions."
