When a forest mass has been harvested following a management program and the size of the stumps are the only evidence, it is possible to estimate diameter, height and volume of standing trees by allometric relationships. In this paper is described an experiment in which 12 mathematical models were fitted to predict normal diameter, total height and stem volume from the diameter of the stump of Pinus arizonica, P. ayacahuite, P. durangensis, P. leiophylla, P. teocote and Quercus sideroxila in San Diego de Tezains, Santiago Papasquiaro municipality, which is located at the northwestern region of the state of Durango and belongs to the Sierra Madre Occidental. A sample of 267 felled trees and linear and non-linear models were used. The fitting of models indicates that there is a linear tendency between normal diameter and total height, in terms of stump diameter, while for the volume of the stump, there is a logarithmic relationship. Also, a similitude among species in regard to the relations of the studied variables was observed. The resulting equations may be applied in the reconstruction of scenes after a forestry intervention occurs or when a catastrophic event takes place.
