Mean acorn crop data for Hastings Reservation (the study site), between 1980 and 2012. Data are the mean number of acorns counted per 30-s sample across all oak trees sampled (N = 250). Data are both the raw number of acorns counted and the mean log-transformed (ln[x+1]) number of acorns counted. Acorns are counted in the fall of year x, and thus correspond to the acorn woodpecker breeding season of year x+1.
