Urban Countryside Biogeography: a decade of comparing the avifauna of a Sydney suburb and reserve

As the human enterprise expands, the task of preserving biodiversity increasingly must be carried out in areas heavily modified by humanity ? the domain of countryside biogeography (Daily 2001; Daily et al. 2001). Countrysides normally are thought of as rural environments. The dividing line between rural and urban is often blurred by suburbs; urban environments represent the expanding end of a continuum of disturbance, the other end of which is the shrinking domain of relatively undisturbed natural areas and wilderness. Because of the growing preponderance of urbanization, ecologists over the past quarter century have increasingly turned their attention to conservation in urban areas.
