Forest recovery after disturbances is important for economic values and ecological processes ... -
Spatial patterns of cultural ecosystem services provision in Southern Patagonia
Martinez Pastur, Guillermo José; Peri, Pablo Luis; Lencinas, María Vanessa; García Llorente, Marina (Springer, 2016-02)Context Although there is a need to develop a spatially explicit methodological approach that addresses the social importance of cultural ecosystem services for regional planning, few studies have analysed the spatial ... -
Suitable conditions for natural regeneration in variable retention harvesting of southern Patagonian Nothofagus pumilio forests
Toro Manríquez, Mónica D.R.; Cellini, Juan Manuel; Lencinas, María Vanessa; Peri, Pablo Luis; Peña Rojas, Karen A.; Martínez Pastur, Guillermo José (SpringerOpen, 2019-06)Background: Variable retention (aggregated and dispersed retention) harvesting proposed for Nothofagus pumilio was designed for timber purposes and biodiversity conservation. Harvesting by opening canopy generates different ... -
