Reference:Foxtail pine range in CA (Griffin & Critchfield 1972). Barbour (1988), Ryerson (1983), Sawyer & Thornburgh (1977).
Comments:Separate populations of foxtail pine represent varieties of Pinus balfouriana [ P. b. var. balfouriana in NorCo and KlaR and P. b. var. austrina in s. SN]. In m-NorCo the series occurs on Franciscan greywacke sandstone, metavolcanic, and schist-derived soils. In su-KlaR, foxtail pine is mostly found on ultramafic-derived soils. In SN it occurs on granitic-derived soils. The two varieties are included in this series.
Plot based descriptions:Keeler-Wolf & Keeler-Wolf (1984a) describe stands at South Yolla Bolly Mountain in Tehama Co. su-NorCo; Keeler-Wolf (1987a) in Keeler-Wolf (1990e) at the Crater Creek candidate RNA, Whipple & Cope (1979) in Keeler-Wolf (1990e) define one association at Mount Eddy candidate RNA, Ke ler-Wolf (1984b, 1989f), Saw-yer & Thornburgh (1971) in Keeler-Wolf (1990e) describe stands at Sugar Creek candidate RNA in Siskiyou Co. su-KlaR; Ball (1976) in Keeler-Wolf (1990e) defines one association at Last Chance RNA in Inyo Co. su-SN.
