The primary
purpose of the Altadena Foothills Conservancy (AFC) is the
preservation of land in Altadena, California, focusing on
the natural foothills that provide a buffer between developed
residential neighborhoods and the rugged San Gabriel Mountains.
AFC works cooperatively with other conservancies in the region
and state.
