Our study examines these potential factors by quantifying reproductive success (numbers of new seedlings and their sizes) and survival and growth of the younger life stages (seedlings and saplings), and by exploring how the timing of grazing, topographical variables, and rainfall limit reproduction, growth, and survival for these life stages, helping to identify potential management and restoration strategies to enhance the population viability of blue oak. We followed a population of blue oak (Quercus douglasii) seedlings and saplings in the Sierra Nevada foothills, measuring adult seed production and initial seedling recruitment (number and size of new seedlings), seedling growth and survival, seedling recruitment to saplings (growing greater than 10 cm in height), and sapling growth and survival. We tested the impacts on these demographic processes of timing and intensity of grazing, light availability, water availability, and individual size. We published our analysis of these data as part of the 8th Oak Woodland Symposium. This data archive contains the underlying data for our analysis plus some data we did not include in our analysis (residual dry matter, photosynthetically active radiation, percent exotic/native cover), including raw data and R and Perl scripts used to format them for analysis, and additional information not included in the conference proceedings.
