Table 1 Mean dry biomass, length, diameter, and bulk density of sugar pine cones collected from the Yosemite Forest Dynamics Plot in 2011. Values that share a superscript within columns are not significantly different. Cone length was not statistically analyzed because it is a principal discriminating attribute in the cone classification system (Figure 2).
