Oregon white oak (Quercus garryana) and California black oak (Q. kelloggii) woodlands are unique ecosystems, yet little is known about their tree establishment patterns, nor the variability of stand structure. Research objectives were: to describe age, stand structure, and tree regeneration in 4 mixed oak-conifer woodlands in northwestern California. Most white and black oaks established from 1850-1910 with rare establishment since 1950 (< 0.05%). Most Douglas-fir trees established since ~ 1950. All sites had high proportions of oak seedling mortality in open stands. These trends likely reflect the effects of altered disturbance regimes enabling the transition to conifer-dominant stands.
