He oversaw well-received television series including "Planet Earth" (2006), "Springwatch" (2005), "Wild China" (2008) and "Life" (2009), as well as the Unit's largest-ever radio production, "World on the Move" (2008), which followed migrating animals live, and Breathing Places, an ambitious multimedia campaign which successfully encouraged thousands of people to undertake hands-on activities with nature.
