Ancient clam gardens nurtured food security

A three-year study of ancient clam gardens in the Pacific Northwest reveals that coastal First Nations people used to reap superior harvests using rock-walled beach terraces.

Her supervisors, who all helped with research and authoring the study, included SFU professors Anne Salomon, an ecologist; Dana Lepofsky, an archaeologist; and University of Washington biologist Kirsten Rowell.
