چکیده
Height-diameter models are fundamental for the inventory of timber, biomass and carbon. Located in central region Mexico, Abies religiosa is a conifer with high timber value that lacks to estimate its height as function diameter. The objective this study was determine local height-diameter model A. trees under mixed-effects approach Tlaxco, Tlaxcala, Mexico. first step consisted evaluating quality fit three growth one power model. We used data 1,539 measured 197 circular plots 1,000 m2. selected Weibull, which adjusted second modelling approach. Our results showed most accurate predictive capacity obtained when using sub-basin covariate clustering factor random effect parameter corresponding asymptote. Under approach, goodness superior traditional by nonlinear least square. Comparatively gains statistics R2, RSME AIC were 12.19 %, 47.99 % 8.46 respectively. proposed robust, reliable, biologically coherent operational application forest management region.
