          Abstract

          RESUMEN: La rehabilitación de bosques templados con especies nativas requiere de ensayos y directrices que permitan alcanzar la recuperación de áreas degradadas del sur de Chile y contrarrestar el desequilibrio ambiental producto de los impactos recibidos. Este documento tiene como objetivo presentar una propuesta teórica de rehabilitación basada en plantaciones en núcleo para mejorar las potencialidades de recuperación de bosques de lenga (Nothofagus pumilio) degradados por incendios en la región de Aysén. La estrategia propone núcleos de lenga rodeados de notro (Embothrium coccineum), que actuaría como planta nodriza para acelerar el desarrollo de plántulas de lenga a través de mecanismos de facilitación, como el mejoramiento de las condiciones microclimáticas, y la protección de posibles daños por herbívoros de las plántulas dentro de cada núcleo. Esta propuesta podría ser utilizada en bosques degradados de lenga, tanto en Áreas Silvestres Protegidas como en bosques productivos, así como en paisajes fragmentados por incendios históricos.

          SUMMARY: The rehabilitation of temperate forests with native species requires trial and guidelines to achieve recovery of degraded areas of southern Chile and counteract the environmental imbalance caused by the impacts received. This study aims at presenting a theoretical proposal of rehabilitation based on cluster plantings to improve the recovery of lenga (Nothofagus pumilio) forests degraded by historical fires in Aysén Region. A rehabilitation strategy based on cluster plantings is proposed, in which individuals of lenga are established together with notro (Embothrium coccineum), the latter as a nurse plant, to accelerate the development of lenga seedlings through facilitation mechanisms, such as the improvement of microclimatic conditions, and protection from possible damage by seedling herbivores within each cluster. This proposal could be used in degraded lenga forests, both in Protected Wild Areas and in productive forests, as well as in landscapes fragmented by historical fires.

          Biodiversity conservation: challenges beyond 2010.

          The continued growth of human populations and of per capita consumption have resulted in unsustainable exploitation of Earth's biological diversity, exacerbated by climate change, ocean acidification, and other anthropogenic environmental impacts. We argue that effective conservation of biodiversity is essential for human survival and the maintenance of ecosystem processes. Despite some conservation successes (especially at local scales) and increasing public and government interest in living sustainably, biodiversity continues to decline. Moving beyond 2010, successful conservation approaches need to be reinforced and adequately financed. In addition, however, more radical changes are required that recognize biodiversity as a global public good, that integrate biodiversity conservation into policies and decision frameworks for resource production and consumption, and that focus on wider institutional and societal changes to enable more effective implementation of policy.
