The ethnobotany of deergrass, Muhlenbergia rigens (Poaceae) : its uses and fire management by California Indian tribes

Deergrass (Muhlenbergia rigens, Poaceae), a once abundant and widespread native perennial bunchgrass in California, was utilized extensively by at least twenty tribes for its flower stalks, incorporated into many types of coiled baskets. The craft of coiled basketry required the annual harvesting of thousands of culms by each village and the frequent setting of small-scale fires in many plant community types to eliminate detritus, recycle nutrients, increase culm production and prohibit shrub or tree encroachment. Detailed examination of Native American past fire management practices will provide insights into the cultural processes that shaped various ecosystem states, and unravel the ecological principles embedded in ancient land management systems. There are at least 300 contemporary Native American weavers and the successful revival of basketry in California is inextricably tied to access to and availability of plant resources on public lands.
