In the last decades the coniferous forests have provided economic benefits for Mexico. However, they demand a management with the least possible impact. Regionalization based on the Germplasm Movement Zones (GMZs) is an alternative for the management of the tree stands that does not limit the economic and technical efforts of the local, state or forest management units. However, few works have been developed with this vision. In order to determine the timber production of the main conifer species of the country in the GMZs, the data on the volume of timber produced from Pinus and Abies species by state from 2013 to 2017 were analyzed. Nineteen pine and one fir species contributed most to the national forest production. Specifically, P. patula, P. douglasiana, P. maximinoi, P. pseudostrobus, P. teocote, P. oocarpa, P. montezumae and P. devoniana provided 81.39 % of the total volume among the pines, and A. religiosa supplied 100 % of the total volume from the Abies genus. Likewise, zones X.3, V.3, XII.5, XII.3, X.1, XII.2, III.1, and III.2 account for 84.14 % of the timber production, and X.3 provided 72.16 % of the fir timber output.
