    Introduction: Estimation of total and merchantable tree volume, as well as of biomass andcarbon, implies the generation of biometric tools essential in forest management and planning.
    Objectives:   To   fit   a   compatible   taper,   volume,   green   weight,   dry   biomass   and   carbonconcentration system for Quercus sideroxyla Bonpl. species using wood density.
    Materials and methods: A database of 522 diameter-height measurements, obtained from 37 trees, was used in the fitting equations. The compatible system (CS) was integrated by 34 equations, which were simultaneously fitted by generalized nonlinear least squares. Taper andvolume   were   the   base   variables   for   estimating   green   weight,   dry   biomass   and   carbonconcentration.
    Results and discussion: All equations were compatible with the stem volume equation, andthe   merchantable   equations   with  the   taper   and   merchantable   volume   equations.   The   fitstatistics showed the efficiency of the equations in global terms and by relative height classes.
    Conclusions: The CS  has the property  of  estimating  taper,  merchantable  volume,  greenweight, dry biomass and carbon concentration at upper-height and by components (stem, totaltree and branches).

    Keyworks: merchantable volume; stem volume; branch volume; aboveground biomass; greenweight
