An interconnected network of protected land and water that supports native species, maintains natural ecological processes, sustains air and water resources and contributes to the health and quality of life for America's communities and people. Also refers to a strategic approach to conservation that addresses the ecological, social and economics impacts of sprawl and the accelerated consumption and fragmentation of open land.
Our natural life support system - an interconnected network of waterways, wetlands, woodlands, wildlife habitats, and other natural areas; greenways, parks, and other conservation lands; working farms, ranches and forests; and wilderness and other open spaces that support native species, maintain natural ecological processes, sustain air and water resources and contribute to the health and quality of life for communities and people. Green infrastructure's components include a variety of natural and restored ecosystems and landscape features that make up a system of "hubs" and "links". Hubs anchor green infrastructure networks, providing origins and destinations for the wildlife and ecological processes moving to or through them. Links are the connections tying the system together and enabling green infrastructure networks to work. Hubs and links range in size, function, and ownership.
