Northern California Coast Northern Focus Area
14.1 Description of Area 14.1.1 The Land The Northern California Coast - Northern Focus Area is composed of coastal Del Norte and Humboldt counties. The boundary extends eastward from the Pacific coast to the top of the first inland mountain range, and encompasses many of the region's existing and former wetlands. The focus area also includes a few important riparian and floodplain areas adjacent to major coastally draining rivers (Figure 13). In this northernmost California County, the coastline tends to be composed of rocky cliffs and high bluffs which rise steeply into the coastal mountain ranges with their deeply cut 14.0 canyons. Two major rivers drain the interior mountain ranges and empty into the Pacific Ocean within the boundary of Del Norte County: the Smith River, which has its origins in north- eastern Del Norte County and southern Oregon, and the Klamath River with headwaters much farther to the NORTHERN north and east in south central Oregon. Humboldt County, to the south, includes portions of CALIFORNIA the California Coast Range and the southern Klamath Mountains. The most extensive coastal wetlands are associated with floodplains in the lower Eel River COAST─ Valley and the Humboldt Bay area. Other significant wetland habitats include Mad River Estuary, Little River Valley, Redwood Creek Estuary, Big Lagoon, NORTHERN Stone Lagoon, and Freshwater Lagoon. Major rivers and streams draining the mountain ranges of Humboldt County include the Eel River, Van Duzen FOCUS AREA River, Mad River, Trinity River, Klamath River, Mattole River, Bear River, and Redwood Creek. Like the Klamath River, the Trinity and Eel rivers have large drainage basins within the Coast Range and the Klamath Mountains.
