Table 1 Average residuals per height and biomass class using the CRM and Jenkins approaches show that while both approaches overestimate low biomass and underestimate high biomass the Jenkins model has a slightly higher overall deviation as well as markedly higher overestimates in low-moderate biomass plots. This trend is not apparent with respect to height class
