Piñon and juniper SCP increased with water availability across the landscape. Juniper (black) and piñon (gray) SCP both increased with increasing mean annual precipitation (MAP). Slopes did not differ significantly between species (p = 0.2, Table S1) and SCP increased, on average, by 0.35 MPa with a 100 mm increase in MAP (p = 0.05, Table 1).
