Division of live tree, snag, and deadwood biomass pools in the Utah Forest Dynamics Plot by diameter class and by susceptibility to Dendroctonus rufipennis (i.e., Picea engelmannii vs. all other species). The diameter division at 33.2 cm DBH separates living biomass into two equal portions, with 1212 trees ≥ 33.2 cm DBH and 22,388 trees 1 cm ≥ DBH > 33.2 cm. Total live biomass was 119 Mg ha⁻¹, total snag biomass was 36 Mg ha⁻¹, and deadwood biomass was also 42 Mg ha⁻¹. Wood identified as Picea but without designation of species was counted as Picea engelmannii
