residents have taken unprecedented measures to protect their open land, and a growing movement seeks not only to preserve these lands but to link them in green corridors. Many land-use and urban planning professionals, along with landscape architects and environmental advocates, have joined in efforts to preserve natural areas. MetroGreen answers their call for a deeper exploration of the latest thinking and newest practices in this growing conservation field. In ten case studies of U.S. and Canadian cities paired for comparative analysis-Toronto and Chicago, Calgary and Denver, and Vancouver and Portland among them-Erickson looks closely at the motivations and objectives for connecting open spaces across metropolitan areas. She documents how open-space networks have been successfully created and protected, while also highlighting the critical human and ecological benefits of connectivity. MetroGreen's unique focus on several cities rather than a single urban area offers a perspective on the political, economic, cultural, and environmental conditions that affect open-space planning and the outcomes of its implementation.
