Efectos ecológicos de las rozas y aclareos de matorral sobre la diversidad del sotobosque

Abstract

[ES]: La práctica de rozas y aclareos del matorral es un tratamiento selvícola llevado a cabo en los bosques de alcornocal, con una serie de objetivos: 1) facilitar las labores de extracción del corcho, realizadas cada 7-9 años, 2) incrementar la producción de corcho, al reducir la competencia con las especies vecinas de matorral y 3) reducir el riesgo de incendios, al disminuir la cantidad de combustible (véase en Torres y Montero, 2000, el capítulo sobre "la selvicultura de los alcornocales del macizo del Aljibe", págs. 58-73). Sin embargo, este tipo de perturbaciones puede suponer un impacto ecológico sobre la regeneración de leñosas y la diversidad de herbáceas a nivel del sotobosque. A escala regional, se han encontrado diferencias en la diversidad del sotobosque, entre el sur de España y el norte de Marruecos, que se explican en parte por el contraste en el tipo de uso y gestión del bosque (Marañón et al. 1999).

[EN]: Shrub-clearing is a frequent sylvicultural practice in cork oak forests. Main objectives are: 1) to facilitate the extraction of bark to obtain cork, every 7-9 years, 2) to increase the cork production reducing competition by neighbour shrubs, and 3) to reduce the risk of fires, decreasing the amount of fuel. However, this disturbance can have ecological impacts on the regeneration of woody species and the diversity of herbaceous understorey.
