This episode explores the landscape history of cities as ecosystems, not ecosystems of business but actual living systems.   New research shows that urban gardens support a greater number of species than an equivalent sized semi-wild rural habitat. As gardeners, as horticulturists, we may want to curate these gardened environments. How much urban landscape should be a “scruffy wild edge-land”? How does looking to the past help us plan the future of cities?  Sarah Beck speaks with historian Ben Wilson about his sixth book, Urban Jungle: The History and Future of Nature in the City.
