Predicted phytolith abundance in soil (% by mass) for California, based on an ensemble model of three algorithms. Gray region indicates locations > 3 average ‘environmental PC’ units away from the nearest three observed phytolith locations. Circles and triangles represent locations with phytolith content above or below the 0.3% threshold identified by Evett and Bartolome[10].
