From: Climate has a larger effect than stand basal area on wood density in Pinus ponderosa var. scopulorum in the southwestern USA

Fig. 4

Sample-level mean values from 1963 to 2016 of basal area increment (BAI, top), ring density (RD, middle), and LW proportion (LWP, bottom) for the six GSLs at three sample heights. Letters indicate significant differences in BAI groupings at the indicated sample height (no differences in RD or LWP were significant).
