| description | The recovery of standing Pinus stock after a harvest in forests treated under irregular and regular forest management systems was evaluated. The management history of five forest properties managed under the Mexican Management Method of Irregular Forests (MMOBI) and twelve under the Silvicultural Development Method (MDS) during the period 1995-96 was analyzed. In addition, in 2004 within these forest properties, 12 basic MMOBI forest management units and 34 basic MDS units were sampled with an intensity of 5 % of their total area, using 1000 m2 circular plots. Of the 17 properties managed, either with MMOBI or MDS in 1995-96, 11 had shifted to another forest planning method by the year 2004. In eight of the 17 properties, management programs for the harvest cycle following the one containing the data for the period 199596 indicated that there were modifications to the delimitation of the basic forest management units. It was found out that by 2004, even though a cutting cycle had almost culminated, the volume per hectare in six of the 12 MMOBI units analyzed and in 19 of the 34 MDS units analyzed were significantly different (5 α= %). The differences are attributed to the changes in delimitation of the basic forest management units and to a low precision of the forest inventories, due to: a) inadequate sampling intensity, b) errors in the estimation of diameters and heights classes, and c) the use of inadequate basal area factors. |

En este trabajo se evaluó la recuperación del volumen de Pinus en pie después de una corta, en bosques tratados con los sistemas de manejo regular e irregular. Para ello se revisaron los antecedentes de cinco predios manejados con el Método Mexicano de Ordenación de Bosques Irregulares ( MMOBI) y doce predios manejados con el Método de Desarrollo Silvícola (MDS). Además, en estos predios, en el año 2004 se muestrearon 12 unidades básicas de manejo del MMOBI y 34 del MDS. La intensidad de muestra fue del 5% y se usaron sitios circulares de 1 000 m2. De los 17 predios estudiados, en 11 ya se había cambiado de método de planeación para el año 2004, en ocho se observó que hubo cambios en la delimitación de las unidades básicas de manejo en los programas posteriores al de la anualidad 1995-1996. Se encontró que en el año 2004, aunque ya había transcurrido casi un ciclo de corta, el volumen por hectárea en seis de las 12 unidades básicas de manejo analizadas del diferencias se atribuyen a los cambios en la delimitación de las unidades básicas de manejo y a unaMMOBI y en 19 de las 34 unidades de manejo del MDS fue significativamente diferente ( α =5 %). Estas baja precisión de los inventarios, causada por: i) inadecuada intensidad de muestreo, ii) errores en la estimación de las categorías diamétricas y de altura y iii) uso de factores de área basal inadecuados.
