Bioclimate model projections for California valley oak (Quercus lobata) and blue oak (Quercus douglasii) indicate that large portions of these species' current distributions will become climatically unsuitable over the next century. My research has assessed these model projections against actual spatial demographic patterns in natural populations. Results indicate that response to climate change in both species may initiate as a local redistribution of recruitment around mesic microrefugia (micro-topographic and hydrologic landscape features), instead of as a whole-scale distributional shift projected by models. Additionally, we demonstrate the importance of incorporating discrete life stage-specific climate sensitivities into bioclimate models. Finally I will present a proposed field study to test the potential success of warm-adapted, non-local genotypes in valley oak restoration, using the spatial variability in recent warming in Southern California.
