This is the New York State edition of the GIC's guide to evaluating and conserving green infrastructure (GI) across the landscape. It provides an historical background to GI, as well as practical steps for creating GI maps and plans for a community. It discusses issues around evaluating green assets, public involvement in the mapping process, and the practical steps in bringing together GIS information into a useful format. It draws from twelve field tests GIC has conducted over the past six years in a diversity of ecological and political conditions, at multiple scales, and in varied development patterns – from wildlands and rural areas to suburbs, cities and towns. This guide is intended to help people make land management decisions which recognize the interdependence of healthy people, strong economies and a vibrant, intact and biologically diverse landscape. Green infrastructure consists of our environmental assets – which GIC also calls ‘natural assets’ – and they should be included in planning processes. Planning to conserve or restore green infrastructure ensures that communities can be vibrant, healthful and resilient. Having clean air and water, as well as nature-based recreation, attractive views and abundant local food, depends upon considering our environmental assets as part of everyday planning.
