DOWNLOAD EBOOKOregon white oak (Quercus garryana) and California black oak (Q. kelloggii) woodlands are unique ecosystems in the Pacific West that support high levels of biodiversity, yet little is known about their current and historic stand establishment patterns, nor the variability of stand structure and its effect on oak-tree growth. With concerns of local extirpation due to native Douglas-fir (Pseudotsuga menziesii) encroachment, my research objectives were to characterize the variability of age and stand structure, current tree regeneration, and oak growth in 10 mixed oak-conifer woodlands from xeric to mesic site conditions in the North Coast region of California. Each site varied from open canopy oak-dominant woodland to closed canopy conifer-dominant forest. Most white and black oak trees established from 1850 to 1910 with minimal (
