Habitats

Redwood forests are interspersed with several other plant communities throughout this ecoregion.


Coastal redwood forests

The dominant forest type in this ecoregion is the coastal redwood forest. These are the tallest forests on Earth, with individual redwood ('' Sequoia sempervirens'') trees reaching heights of . These forests are generally found in areas exposed to coastal fog. In the north, they occur on upland slopes, in riparian zones, and on riverine terraces. In the south, where annual precipitation is lower, they are constrained to coves and ravines. Coast Douglas-firs (''
