Anthropogenic Impacts Allowed for the Invasion of Understory Species, Affecting the Sustainability of Management Practices in Southern Patagonia
Rosas, Yamina Micaela; Peri, Pablo Luis; Cellini, Juan Manuel; Lencinas, María Vanessa; Kepfer-Rojas, Sebastian; Kappel Schmidt, Inger; Pechar, Sebastián; Barrera, Marcelo Daniel; Martínez Pastur, Guillermo José (MDPI, 2024-01-16)Forest management aims to preserve integrity and ecosystem resilience. Conservation and species invasion patterns must be determined in managed landscapes. The objectives of this study were to identify proxies that allowed ... -
Canopy structure analysis for estimating forest regeneration dynamics and growth in Nothofagus pumilio forests
Martínez Pastur, Guillermo José; Peri, Pablo Luis; Cellini, Juan Manuel; Lencinas, María Vanessa; Barrera, Marcelo Daniel; Ivancich, Horacio Simón (Springer, 2011-04-08)Introduction Silviculture systems applied in Nothofagus pumilio forests are based on opening the canopy to stimulate natural regeneration by modifying light and soil moisture. The objective is to evaluate regeneration ... -
Changes in forest structure values along the natural cycle and different management strategies in Nothofagus antarctica forests
Martínez Pastur, Guillermo José; Rosas, Yamina Micaela; Chaves, Jimena Elizabeth; Cellini, Juan Manuel; Barrera, Marcelo Daniel; Favoretti Bondar, Santiago; Lencinas, María Vanessa; Peri, Pablo Luis (Elsevier, 2021-04-15)Ecologically sustainable forest management aims to preserve ecosystem integrity by providing wood and non-wood values. For this, it is necessary to determine the losses produced by the different management practices in ... -
Conservation values of understory vascular plants in even- and uneven-aged Nothofagus antarctica forests
Martínez Pastur, Guillermo José; Rosas, Yamina Micaela; Cellini, Juan Manuel; Barrera, Marcelo Daniel; Toro Manríquez, Mónica D.R.; Huertas Herrera, Alejandro; Favoretti Bondar, Santiago; Lencinas, María Vanessa; Peri, Pablo Luis (Springer, 2020-09)Usually, stands with aging trees are considered forests with higher conservation values, regardless their structural diversity and other functional attributes. Natural stands present a wide range of age structures, from ... -
Effects of long-term low intensity silviculture and habitat on birds in Nothofagus antarctica forests of south Patagonia
Benitez, Julieta; Barrera, Marcelo Daniel; Sola, Francisco Javier; Blazina, Ana P.; Martínez Pastur, Guillermo José; Peri, Pablo Luis; Lencinas, María Vanessa (Elsevier, 2022-04-30)Low intensity silviculture has been used to decrease the impact of forest harvesting, for example, on bird species and structural diversity. The objective of this work was to analyse the long-term effect of thinning on ... -
Environmental variables influencing regeneration of Nothofagus pumilio in a system with combined aggregated and dispersed retention
Martínez Pastur, Guillermo José; Cellini, Juan Manuel; Lencinas, María Vanessa; Barrera, Marcelo Daniel; Peri, Pablo Luis (Elsevier, 2011-01-01)The current silvicultural prescriptions for Nothofagus are designed to stimulate natural regeneration by opening the canopy. One of these methods is variable retention, which can include either or both aggregated and ... -
Influencia de factores bióticos y abióticos en el crecimiento de la regeneración pre- y post-cosecha en un bosque de Nothofagus pumilio
Martínez Pastur, Guillermo José; Cellini, Juan Manuel; Barrera, Marcelo Daniel; Lencinas, María Vanessa; Soler Esteban, Rosina Matilde; Peri, Pablo Luis (2017)Para definir nuevas prácticas silvícolas es necesario conocer los procesos ecosistémicos involucrados y los impactos que generan. Las propuestas implementadas generaron diversos interrogantes relacionados al dosel remanente, ... -
Knowledge arising from long-term research of variable retention harvesting in Tierra del Fuego: where do we go from here?
Martínez Pastur, Guillermo José; Rosas, Yamina Micaela; Toro Manríquez, Mónica D.R.; Huertas Herrera, Alejandro; Miller, Juan A.; Cellini, Juan Manuel; Barrera, Marcelo Daniel; Peri, Pablo Luis; Lencinas, María Vanessa (Springer Open, 2019-07)Nothofagus pumilio forests in Tierra del Fuego are the southernmost forests in the world, where extreme climate conditions represent a challenge to attain sustainable forest management. Retention forestry was proposed as ...
