Retention Forestry in Southern Patagonia: Multiple Environmental Impacts and Their Temporal Trends
Harvesting with variable retention (VR) applied in Nothofagus forests combines two types of retention: patches of original forest (aggregates) and single isolated homogeneously distributed trees (dispersed). This study assesses the assumption that VR maintains mature forests conditions after harvest...

| description | Harvesting with variable retention (VR) applied in Nothofagus forests combines two types of retention: patches of original forest (aggregates) and single isolated homogeneously distributed trees (dispersed). This study assesses the assumption that VR maintains mature forests conditions after harvesting by synthesizing 605 individual results from long-term studies in two regions of Tierra del Fuego (Argentina) with permanent monitoring. VR effects on (i) forest structure, (ii) microenvironment, (iii) biodiversity, and (iv) forest reproduction, were investigated. Aggregated retention had no effect on forest structure and microenvironmental variables, but increased biodiversity variables and forest reproduction compared to unmanaged primary forest (control). Dispersed retention negatively affected the forest structure, increased biodiversity, but did not affect microclimate and forest reproduction when compared to primary forest. Thus, the ecological conditions of N. pumilio forests are influenced by variable retention harvesting, but direction and magnitude of the effect depend on the treatment and differ among groups of variable. Inside aggregates several primary forest components and conditions were maintained. |

El aprovechamiento con retención variable (RV) en los bosques de Nothofagus combina dos tipos de retención: bosquetes de bosque primario (agregada) y árboles individuales aislados distribuidos homogéneamente (dispersa). Este estudio evalúa la hipótesis de que la RV mantiene las condiciones de bosque maduro después del aprovechamiento, mediante una síntesis de 605 resultados individuales provenientes de diferentes estudios a largo plazo en dos regiones con monitoreo permanente en Tierra del Fuego (Argentina). Se investigaron los efectos de la RV en (i) la estructura del bosque, (ii) variables microambientales, (iii) la biodiversidad, y (iv) variables reproductivas del bosque. La retención agregada no tuvo efecto sobre la estructura del bosque y las variables microambientales, pero aumentó las variables de biodiversidad y de reproducción del bosque en comparación con los bosques primarios no manejados (control). La retención dispersa afectó negativamente a la estructura del bosque y aumentó la biodiversidad, pero no afectó al microclima o a la reproducción del bosque, en comparación con los bosques primarios. Por tanto, las condiciones ecológicas de los bosques de N. pumilio se ven influenciadas por el aprovechamiento con retención variable, pero la dirección y la magnitud del efecto dependen del tratamiento y difieren entre grupos de variables. Dentro de los agregados se mantuvieron varios de los componentes y las condiciones de los bosques primarios. EEA Santa Cruz Fil: Soler Esteban, Rosina Matilde.
