MR 226 MR 221MR 222MR 223MR 224MR 225MR 226MR 227


Moist, productive forests in the California Coast Range province are dominated by Douglas-fir and western hemlock, and contain most of the coastal redwood forest. The southeastern portion of this modeling region falls within the Central California Chaparral and Oak Woodlands ecoregion. Only a small proportion of the California Coast Range province is administered by federal agencies.
