| description | Pinus hartwegii forests are susceptible to the attack of forest pests, so sanitation interventions in the stands of this species must be analyzed. The objective of this work was to evaluate the effects of sanitation cuts on the radial growth of residual trees, in monospecific stands of P. hartwegii of the Área de Protección de Flora y Fauna Nevado de Toluca. Ten measuring sites of remnant trees and stumps were established in stands operated during 2016 (1000 m2) in the West and East slopes of the volcano. The period 2013-2015 was considered as prior to sanitation, and 2016-2018 as after sanitation. The distribution pattern, horizontal and vertical structure were analyzed. Two density indices and two proficiency indices were calculated. Wood cores were collected in all individuals and the widths of the growth rings were measured by dendrochronological techniques. Growth was standardized by series of basal area increment (IAB). The growth of the remaining trees located on the periphery of the stumps was significantly different between the exposures. The BAI increased 37.3% after sanitation in the West exposure, while in the East exposure the BAI increased 61.6%. The remaining trees located between 2.5 and 5 m with respect to the stump had higher BAI in both exposures. Pinus hartwegii forests respond positively to sanitation cuts with a statistically significant increase in IAB. |

Los bosques de Pinus hartwegii son susceptibles al ataque de plagas forestales, por ello las intervenciones de saneamiento en los rodales de esta especie deben ser analizadas. El objetivo de este trabajo fue evaluar los efectos de las cortas de saneamiento sobre el crecimiento radial del arbolado residual, en rodales de P. hartwegii del Área de Protección de Flora y Fauna Nevado de Toluca. Se establecieron diez sitios de medición de árboles remanentes y tocones en rodales intervenidos durante 2016 (1000 m2) en las exposiciones Oeste y Este del volcán. Se consideró el período de los años 2013-2015 como previo al saneamiento, y 2016-2018 como posterior al saneamiento. Se analizaron el patrón de distribución y la estructura horizontal y vertical. Se calcularon dos índices de densidad y dos índices de competencia. Se colectaron núcleos de madera en todos los individuos y se midieron las anchuras de los anillos de crecimiento mediante técnicas dendrocronológicas. Se estandarizó el crecimiento mediante series de incremento en área basal (IAB). El crecimiento de los árboles remanentes ubicados en la periferia de los tocones fue significativamente diferente entre las exposiciones. El IAB aumentó 37.3% después del saneamiento en la exposición Oeste, mientras que en la exposición Este el IAB aumentó 61.6%. Los árboles remanentes ubicados entre los 2.5 m y 5 m con respecto al tocón tuvieron mayores IAB en ambas exposiciones. Los bosques de Pinus hartwegii responden de manera favorable a las cortas de saneamiento con un aumento estadísticamente significativo en el IAB.
