The Pialligo Redwood Forest consists of 3,000 surviving redwood specimens, of 122,000 planted, 500 meters east of the Canberra Airport. The forest was laid out by the city's designer Walter Burley Griffin, though the city's arborist, Thomas Charles Weston, advised against it.[2] The National Arboretum Canberra began a grove of Sequoiadendron giganteum in 2008.[3] They also grow in the abandoned arboretum at Mount Banda Banda in New South Wales.[citation needed]
