Comments:Tanoak is an important component in several series. The term "mixed evergreen forest" is most commonly associated with tanoak, but stands called mixed evergreen forest vary in composition (Barbour 1988b, Sawyer et al. 1977). The original concept of mixed evergreen forests was used to describe hardwood stands in the Santa Lucia Mountains where tanoak, madrone, live oaks and California bay grow. This was Cooper's (1922) broad sclerophyll formation. Munz (1959) and Whittaker (1960) expanded the term mixed evergreen to include Douglas-fir - tanoak series stands. Azet et al. (1992) argue that tanoak is the primary naturally regenerating species in sw. OR, whereas Douglas-fir importance is a function of fire history (Azet & Wheeler 1982). Jimerson (1993) comes to the same conclusion for l-KlaR. The low elevation associations are called Tanoak series even though Douglas-fir is an important component. Sawyer et al . (1977c) called stands in Nor-CA of Douglas-fir, tanoak, and madrone Pseudotsuga / hardwood forests. Other authors (Keeler-Wolf 1990, Bingham & Sawyer 1991, 1993, Stuart 1993) refer to Douglas-fir/hardwood forests in Nor-CA. [The slash indicates the two tiered character of the stands].
Plot based descriptions:Griffin (1976), Borchert 1987) in Keeler-Wolf (1990e) define a Sugar pine -tanoak/poison-oak association at South Fork of Devil's Canyon (part of Cone Peak Gradient RNA) in Monterey Co. m-CenCo; Sawyer (1981a) a Tanoak/California coffeeberry association at Adorni candidate RNA in Humboldt Co. l-KlaR; Gudmunds & Barbour (1987) describe stands along Middle Yuba River m-SN.
