Salmon Runs (IMAGE) University of California - Santa Cruz Caption Nature has always been a source of artistic inspiration and materials, and variation, both across species and within species, an important contributor to art and culture. This painting illustrates intraspecific variation in sockeye salmon runs and was created from natural botanical pigments foraged from North American native species, including Western red cedar (bark), red alder (cones), staghorn sumac (berries), and salal (berries).
