Vegetation Growth at a Once-Flooded Santa Ynez River
Vegetation Growth at a Once-Flooded Santa Ynez RiverVegetation grows abundantly on a once-flooded region of the Santa Ynez River. Located 5 ft adjacent from this picture is the actual flowing region of the stream. It is impressive to see the abrupt change in vegetation near stream environments.
