Photo: Diane Edwardson, May 26, 2013. Perennial native Cudweed migrated down slope in the mouth of Red Car Canyon. For decades, it was rooted about 20' upslope from it's current location. Rain, brush clearance, erosion and dogs playing on the slope encouraged the plant to move downward in the past few years. (Click on photo to enlarge.)
