Separate analyses were conducted for total pollinator abundance, total pollinator richness, and the abundance and richness of each of the three most common insect orders observed (Hymenoptera, Lepidoptera, and Diptera). Significant predictors are highlighted in yellow with p-values in bold. Marginal ( $R_{m}^{2}$ ) and conditional ( $R_{c}^{2}$ ) R² values are listed for each final model.
