description Camas Swale Prairie Overview
Camas Swale Prairie is a historical wet prairie region situated within the Willamette Valley of Oregon. The ecosystem is defined by its poorly drained soils and the dense presence of blue camas, a flowering plant that historically bloomed across the valley. Before widespread agricultural conversion, the Kalapuya people actively managed these prairies and harvested the plant's edible bulbs as a primary food source.
