Table 1 Predictor variables used in models of the distribution of woody species in Yosemite National Park, California, USA (1991 to 2017). Each model includes up to five potential predictors of species presence or absence. Predictor variables consist of actual evapotranspiration (AET), climatic water deficit (Deficit), quadratic effects (AET2, Deficit2), a dichotomous variable indicating whether the plot had burned (BURN), fire return interval departure (FRID; for plots that had not burned), and differenced normalized burn ratio (dNBR; for plots that burned). For variable definitions and model comparison sets, see text
