Blueberries were domesticated starting in 1911, with the first commercial crop in 1916. Huckleberries of all varieties are not fully domesticated,
California mixed evergreen forest forests, and Sierra Nevada lower montane forest. The forests of each ecoregion have a somewhat different plant community composition. The mixed evergreen forests of the Klamath Mountains-Siskiyou Mountains occur above 300 meters (1000 ft) elevation, and are of four main types. Douglas-fir forests are found on gentle slopes, north-facing slopes, ridges with deep soil, and river terraces with deep sediments, usually underlain with sedimentary rocks. Coast Douglas-fir ("Pseudotsuga menziesii" ssp. "menziesii") is the predominant tree, occupying up to 70% of the forest cover. Broadleaf evergreen trees are relatively few. Tree species of secondary importance are: On granite soils, a similar
