This is a case study of Canberra, the capital city of Australia. Traced here is the creation of a city beginning with a barren site in 1913 and its growth to a modern city one hundred years later. Especially significant in the growth of this city is the creation of an infrastructure of forest prior to the actual building of the city. Not only was the forest essential to making the city habitable in the harsh climate of central Australia, but the forest patterns set down in the beginning have continued to shape the ongoing evolution of the city ever since. Treed Infrastructure continues to be an essential utility maintained along with the other utilities and public functions that make the city habitable.
