Resumo: | Centuries of exploiting resources on Macaronesian islands left a significant footprint on their landscapes, even in areas where human activity would seem to be virtually absent. To clarify such interference, this paper explored how the impact of land use determined some attributes of current laurel forest landscape. Focused on communities dominated by heath and Morella faya, this work analyzed the effect of land use on their physiognomy and floristic composition, challenging the interpretation as climax communities. Based on a synchronic approach, the collected data supported a dynamic interpretation of such communities, installed on areas disturbed by human activities over long periods in the past. The combination of floristic composition, structure and land-use proxies suggested that such communities should be interpreted as subseral communities. This interpretation led to the idea that human factor should be considered as a critical driving force shaping landscape. Such an approach, promoting an adjustment in the scientific interpretation, assumed that current attributes of such communities were derived from past land-use options and do not represent a single response to abiotic conditions. Without questioning the value of those communities for conservation, that approach pointed out that protection measures should consider the potential occurrence of significant changes in terms of floristic composition and structure at medium term in that type of communities. |

Para aclarar la intensidad de la interferencia antrópica, este trabajo analiza cómo el impacto de la actividad humana determinó algunos rasgos del paisaje actual de la laurisilva. Se estudian comunidades dominadas por brezo y Morella faya para conocer el efecto del uso del territorio en su composición florística, cuestionando su interpretación como comunidades climácicas. La información que se aporta fundamenta una interpretación dinámica de estos bosques, localizados en áreas explotadas durante siglos. La combinación de datos de composición florística y estructura con los del uso del suelo indica que estas comunidades deben ser consideradas como etapas de sustitución de las climácicas. Esta interpretación revela que la explotación antrópica debe ser considerada como un factor importante de la dinámica del paisaje. Este enfoque propone un cambio en la explicación científica, al reforzar la idea de que las características actuales de estos bosques no constituyen una respuesta exclusiva de las condiciones abióticas. Sin poner en cuestión su valor para la conservación, esta perspectiva defiende que las políticas de protección deben contemplar la posibilidad de que a medio plazo puedan ocurrir cambios importantes en la composición florística y la estructura de estas comunidades.Facultad de Ciencias Forestales, Universidad Austral de Chile2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/106841http://hdl.handle.net/10316/106841https://doi.org/10.4067/S0717-92002019000300299eng0717-9200Arozena, M.
