HERNANDEZ RAMOS, Jonathan et al. Compatible taper-volume commercial system for Swietenia macrophylla King (mahogany) in Quintana Roo, Mexico. Madera bosques [online]. 2018, vol.24, n.3, e2431441.  Epub 26-Nov-2018. ISSN 2448-7597.  https://doi.org/10.21829/myb.2018.2431441.

The volume estimation is important to develop and implement forest management plans. Therefore, knowing the profile of stem, and forest products distribution allows to obtain objective financial assessments of products distribution for commercial trees. The limited information available about models and volume systems to quantify the merchantable volumes in tropical forests, led the authors to consider the purpose of generating a compatible segmented system taper (d) with merchantable volume (Vc) for Swietenia macrophylla King (Mahogany) in Quintana Roo tropical forests. Sample size was of 116 trees distributed in the central and southern parts of the state; with taper variables, commercial and total volume three compatible d-Vc systems of the segmented type were adjusted. The best statistical fit was reached with the Fang system, which was readjusted correcting heterocedasticity and autocorrelation. The first three parameters of this system correspond to a Schumacher-Hall model employed to estimate total volume. Dendrometric shape change points in the trunk are located at 5.6% and 83.1% in relation to total height. The form factor determined was 0.47 and slenderness ratio 0.48. Cubing system is a quantitative tool to support the development of forest management plans for S. macrophylla.
