Item Evaluación de la fauna vertebrada terrestre en bosques nativos y de exóticas asilvestradas en el Parque Nacional Nonguén.(Universidad de Concepción, 2024) Saavedra Ariz, Kharla; Echeverría Leal, Cristian Mauricio; Moreira Arce, Darío AlejandroThe current ecological crisis and the accelerated decline of biodiversity, driven by the high demand for anthropogenic resources, have led to the degradation of ecosystems and the loss of biological communities that took millions of years to develop. Nonguén National Park, affected for years by degradation processes and loss of native forest, is one of the few state protected areas that still preserves high levels of endemism and diversity. However, little is known about the impact of the invasion of exotic species on the terrestrial vertebrate communities of this unit. Therefore, the present study aimed to evaluate the faunal community of native and feral exotic forests and its relationship with the ecosystem attributes of these forest communities. The systematization and analysis of the camera traps was carried out using CameraSweet software, in addition to the characterization of the ecosystems through structural and compositional indices. The results showed that, although the highest detection and diversity of birds and mammals recorded was associated with native forest ecosystems with higher ecosystem complexity, certain groups of species more tolerant to habitat degradation and loss are able to use ecosystems dominated by feral exotics, benefiting from it. Thus, improved management of these areas, particularly through the development of understory, structural complexity and multi-layered complexity, could play a key role for wildlife.
