The study area is located on the private property “Las Veredas” in the municipality of San Dimas, in Durango, Mexico (Fig. 1 ). Data collection was carried out in two sub-stands: (1) clear-cutting with immediate plantation of 21.4 ha located at coordinates 24°20′40″ N and 105°51′20″ W with an elevation of 2,600 m, and (2) seed-tree cutting of 10.2 ha located at 24°20′30″ N and 105°50′58″ W at 2,800 m altitude.
The climate in the study area is temperate with summer rains (CW) and the temperature ranges between −3 and 18 °C (García, 2004 ). The average slope in the clearcut is 9%, while in the seed-tree cutting is 27%. The most frequent rains occur between July and September, which provide an average annual rainfall of 1,000 mm. The soil of both stands is similar and may be classified as Umbrisol (INEGI, 2007 ). The characteristic vegetation is mixed coniferous and broadleaf forests. The first type is dominated by pines, of which the following stand out: Pinus durangensis, P. cooperi C.E. Blanco, P. teocote Schl. et Cham. and P. strobiformis Engelm. Of the broadleaves, the oaks stand out, among these: Quercus rugosa Née and Q. sideroxyla Bonpl. There are also trees of some ecologically important species of the genera Juniperus, Arbutus and Alnus, among others (González-Elizondo et al., 2012 (link)).
