摘      要：Background It is necessary to determine the implications for managing forest stands using variable retention harvesting for maintaining carbon and for calculating the effects of different harvesting practices on above-and below-ground carbon balance in forest *** this context,forest carbon management has gained more attention among managers and policy-makers during recent *** aim of this study was to determine carbon pool dynamics in different forest ecosystem components after variable retention harvesting(VRH)to characterize the ecological stability and quantify the recovery rate through the years-after-harvesting(YAH).Methods Carbon pool compartmentalization of 14 different components was determined in 60 harvested and primary unmanaged forests during the first 18 YAH in Tierra del Fuego(Argentina).We compared them using uni-and multi-variate methods,relativizing the outputs with primary unmanaged *** We determined the effectiveness to retain carbon components in post-harvested stands under different retention strategies(aggregated ***).The balance among carbon pool components changed between managed and unmanaged stands across the YAH,and was directly related to the impact *** retention improved the ecological stability of the harvested areas,where the below-ground components were more stable than the above-ground *** recovery rate was directly related to the post-harvesting natural dynamics of the *** studied period was not enough to fully recover the C levels of primary unmanaged for-ests,but VRH showed advantages to increase the C pools in the managed *** Promoting VRH can improve sustainable forestry at the landscape level and in the long term,generating positive synergies with biodiversity and the provision of ecosystem *** study provides important new insights into forest carbon management,in particular to setting standards in carbon projects and sets the ground
