The aim of this work was to adjust diameter distribution, hypsometric relation, taper and volume models to characterize the dendrometric relations on remaining fragments of Pinus sp. from stands of the 1970s, in the region where the Reserva de Desenvolvimento Sustentável Veredas do Acari is located, north of the state of Minas Gerais. The identification of the Pinus sp. fragments and its mapping was made. Biometric data were gathered from trees for modeling the diameter distribution, hypsometric relationship, taper and tree volume. The selection criteria for the models consisted on evaluation of the adjusted determination coefficient, standard error of estimate in percentage, F-test, regression coefficients significance and residuals graphical analysis. The Beta function, Naslünd, Max-Burkhart and Schumacher-Hall models were adequate to describe, respectively, diameter distribution, hypsometric relationship, taper and tree volume for Pinus sp., on fragments of the 1970s, in the state of Minas Gerais.
