Green Infrastructure: Our Natural Life Support System

When you think of the word, "infrastructure", what comes to mind?  Roads, water and sewer
lines, telephone lines, schools or water treatment plants, perhaps?  We often think of these
types of infrastructure as bray infrastructure" or "built infrastructure".   By definition,
infrastructure refers to "the basic, underlying framework or features of a system or
organization;  the fundamental facilities and systems serving a country, city, or area". Built
infrastructure is developed as systems created to support the many needs of growing
communities.

When we talk about green infrastructure, we are referring to the underlying framework of natural
systems
that serve a country, city, or area. Our green infrastructure is an interconnected
network of natural lands and other open spaces, including forests, streams and rivers,
meadows, farmlands, wetlands, ridge tops, bogs, caves that provide key services to our
communities.  These services included clean air and water, food and fibers, wood products,  
recreation opportunities, and many others. Healthy natural systems provide wildlife habitat for
critters, soils and micro-climates for plants to survive, and ensure important ecological functions
that sustains interdependent web that supports all living things.   

A green infrastructure network includes:
  • Natural areas and green spaces, including forests, streams, lakes, meadows, balds,
    bogs, and wetlands that provide habitat for wildlife and sustain ecological processes.
  • Recreation lands, including trails, parks, and rivers
  • Agricultural Lands, including farms and forests
  • Cultural Sites, including historic sites and other sites important in preserving our region’s
    heritage

A System of Hubs, Links, and Sites

A Green infrastructure network can be envisioned as a system of hubs, links and sites.

  • Hubs are large blocks of unfragmented natural systems that anchor green infrastructure
    networks.  Hubs provides space for native plants and animal communities and an origin
    or destination for wildlife, people and ecological processes moving through the system.
    Examples of hubs in our region include:  Pisgah National Forests, DuPont State Forest,
    Gorges State Park.

  • Links are the linear corridors that connect the hubs and tie the system together.  These
    linkages are critical to maintaining vital ecological processes and maintaining the health
    and biodiversity of wildlife populations; Linkages are often river corridors, greenways, or
    trail systems which may also provide recreation value for residents and visitors.
    Examples of potential linkages in our region include: the French Broad River, Blue Ridge
    Parkway, and the Appalachian Trail.

  • Sites are smaller areas of green space that contribute ecological and social values to
    the region's communities.  Sites may or may not be attached to the network formed by
    the hubs and links, and may include community parks, recreation areas, and cultural
    sites. Examples of sites in our region may include Jackson Park in Hendersonville,
    Azalea Park or Carrier Park in Asheville, or the Carl Sandburg House (National Historic
    Park) in Flat Rock.
