One major theme that our Integrating Habitats winning team entry was the ability to address the interwoven patterns of urban fauna and urban form. There are numerous reasons why keeping a vital mix of flora, and fauna, along with people, is essential to the proper functioning of cities and urban processes. This investigation of species flows really shaped the entire site plan - to avoid conflicts between human users and fauna while maintaining possible interactions between the two.

While notable and disturbing on a base level, it could actually create evolutionary splits in the rural / urban species of birds as they adapt to environmental stimuli (via BLDGBLOG): "If singing and hearing diverge enough, urban birds may be less likely to find the vocals of rural birds attractive, or even to recognise them as members of the same species. These changes could serve to eventually split populations into genetically distinct urban and rural species. Alternatively, different populations of the same species might adopt differing strategies to cope with urban noise, leading eventually to a species split occurring in birds living in the same neighbourhood."

Perhaps what I'm talking about is all of us changing our tune - when it comes to doing better design and planning?
