A central goal of New Urbanism (NU) is to provide alternatives to suburbs through ecologically sound designs and more natural communities. This article situates NU environmental rhetoric culturally and analyzes why this form of nature is being promoted now. I argue that NU anthropocentric understandings of nature reflect and resonate with dominant mainstream environmental ideas in American culture. To understand why NU planners may uncritically adopt these socially and spatially limited understandings of nature, I discuss the institutional contexts of the planning profession. For various reasons, planners historically have understood nature in geographically restricted ways, as Utopian garden, mappable data, and consumer product. More recently, NU ideals of community have been defined by representations of nature that may be construed by consumers as a form of green politics. This article concludes by stressing the need for further research and advocating more inclusive understandings of human-environment relations in the planning process
