Carolyn Smith collecting beargrass in Klamath National Forest, 2015. For beargrass to be supple enough for weavers to use in their baskets, it needs to be burned annually. Ideally, it is burned in an intentionally set cultural fire, where only the tops are burned, leaving the roots intact. Prescribed fires in the Klamath National Forest are few and far between, so weavers “follow the smoke” and gather, when they can, after wildfires sweep through the landscape.
