Determinación y gestión forestal de un corredor biológicos para aves endémicas de bosques templados "Hotspot" de biodiversidad

Abstract

Los bosques naturales del mundo han sufrido un proceso de deforestación sin precedentes en la última mitad del siglo XX. Además de la pérdida de superficie forestal, los bosques remanentes han sido intensamente fragmentados. Ambos procesos de degradación de ecosistemas son fenómenos que ocurren a escala global y constituyen problemas ambientales graves por su impacto sobre la biodiversidad. En aras de la conservación de la biodiversidad de estos ecosistemas degradados, se han buscado soluciones de gestión que permitan realizar una conectividad de zonas con alto valor de biodiversidad, así como desarrollar una mejor conservación de estas zonas, gestionándolas como una superficie continua de bosques. En este marco nace el concepto de corredor biológico (CB). La presente investigación demuestra la aplicabilidad de un CB como herramienta de gestión para la conservación de aves endémicas de los ecosistemas de bosques templados del sur de Chile, los cuales son definidos como “Hotspot” de biodiversidad mundial. Se ha diseñado, a tal fin, un corredor biológico en la cordillera de Nahuelbuta para aves endémicas de los bosques templados de Chile, sobre la base, principalmente, de su selección de hábitat. El corredor diseñado cubre 10773,5 ha, las cuales son, en su mayoría, zonas de pendientes media-bajas, expuestas a solana o semiumbría y con vegetación dominada por especies de los géneros Nothofagus y Nothofagus con Araucaria. Delimitar claramente un corredor a través de variables aplicables a la planificación forestal nos permitió generar propuestas para una gestión de estos bosques que apoye, tanto la conservación de especies de fauna endémicas frágiles características de estos bosques, como el uso sustentable de los recursos naturales de estos ecosistemas forestales, constituyentes, como se ha dicho, de un “Hotspot” de biodiversidad mundial.

World's natural forests have suffered a deforestation process unprecedented in the last half century XX. Furthermore, the reductions in forest area have contributed to heavily fragmenting the remaining forests. Both processes of ecosystems’ degradation are phenomena that occur globally and constitute serious environmental problems with major impacts on biodiversity. With the purpose of conserving the biodiversity of these degraded ecosystems, management solutions have been looked out that permit ensuring a better conservation of these areas through establishing the connectivity of forest areas of high biodiversity value. Therefore, the efforts made towards managing fragmented areas as a continuous forest area resulted in the concept of biological corridor (BC). This research demonstrates the applicability of this management tool for the conservation of endemic birds of temperate forest ecosystems in southern Chile, which are defined as a "hotspot" for global biodiversity. Therefore, a biological corridor, mainly based on habitat selection, has been designed for the endemic birds of temperate forests in the mountains of Nahuelbuta. The corridor designed covers 10773.5 ha, which are mainly located in areas of medium-low slope, exposed to sunshine or half-shade and vegetation dominated by species of Nothofagus and Nothofagus with Araucaria. To clearly design a corridor through the use of variables applicable to forest planning allowed us to generate proposals for forest management activities that support the conservation of the fragile endemic fauna of these forests and the sustainable use of natural resources in these forest ecosystems that represent a "hotspot" of global biodiversity.
