During the last three decades, research indicates that there is a general correspondence of coast redwood forests and coastal fog-stratus cover, but the present-day pattern of fog-stratus provides only a modest predictor for the overall outlines of the species range. The redwood's range seems to be determined more by the distribution of summer fog than the actual amount of rainfall.
