It has been observed that city trees grow more quickly and robustly than their forest-dwelling cousins. The abundance of airborne carbon dioxide in urban environments is absorbed and stored by our arboreal architectures and, in effect, act as a recording device for the city's changing environment. When, where, and which trees were planted has always been directed by the dominant theories of modern urban life and by who ruled the streets. In this way, like the study of changing architectural styles, a tree in the city is a document of the actions of human inhabitation. Collected portraits of Dresden trees tell a story about the city.
