On dry, windy slopes and ridges, redwood growth is limited by water stress. Here, trees may reach an average height of 200 feet (61 meters) or less. At higher elevations, and further inland, redwood seedling establishment is limited by hotter, drier conditions, and the redwood forest gives way to a mixed evergreen forest. Dry forest species include Douglas-fir, tanoak, madrone, California bay, chinquapin (Chrysolepis chrysophylla), canyon live oak (Quercus chrysolepis), and Jeffrey pine (Pinus jeffreyi).
