A guide to creating community-based art installations using green waste, invasive species and natural materials.

Invasive-species control, green-waste management, urban gardening, and traditional crafts can all be brought together to strengthen community relationships and foster responsible land stewardship. Simple, easily taught, creative techniques applied with shared purpose become the modern-day equivalent of a barn raising or a quilting bee.
