Planet Drum Foundation (PDF) is a 501(c)(3) nonprofit ecological educational organization that has been active in the San Francisco Bay Area of California and worldwide since 1973. For over thirty years PDF has had a unique role in promoting awareness of and activities that pertain to bioregions. A bioregion is defined as a distinct geographical area with coherent and interconnected plant and animal communities, and natural systems (often defined by a watershed) and the cultural values that human residents have developed for living in harmony with these natural systems. PDF is widely credited with first identifying the concept of bioregionalism as a distinct subsection of ecology. To promote truly sustainable strategies for inhabitation of the earth, PDF seeks to enhance the intimate connection of people with their bioregions, or “life-places.”
PDF provides an effective grassroots approach to ecological education emphasizing sustainability, community self-determination and regional self-reliance. Through its projects, publications, speakers, classes and workshops, PDF provides guidance, resources, and networking capability to many bioregional groups, local organizations and individuals. Flowing naturally out of our influence and leadership, bioregionalism has become practice in the cultural and ecological restoration of hundreds of watersheds in the U.S., Japan, Latin America, Australia, and Italy.
