The aim of this study was to provide optimal silvicultural guidelines for the maintenance of low understory vegetation cover in maritime pine (Pinus pinaster Ait.) stands in Mediterranean areas prone to the occurrence of forest fires. An extensive data set from maritime pine stands of northern Portugal was used to assess the effect of stand density on the understory cover. A statistically significant relationship between the spacing-top height factor (Fw) and the understory cover was found. An ecologically-based density regulation model was developed based on Fw = 0.21, which provided the optimal stand density and canopy cover to prevent the understory growth and proliferation, thereby reducing the vulnerability to forest fire and ensuring at the same time the highest values of stand yield. The developed model represents a supporting tool for density regulation of maritime pine stands in areas prone to forest fires. The representativeness of the supporting data set (in terms of number of sample plots and variability of the stands characteristics) provides confidence in the generalization of our results to different maritime pine stands in the Mediterranean area. This study suggests that managing stand density may be an effective adaptive management procedure which can help reducing the forest fire hazard.

La presente investigación está orientada a determinar los factores paisajísticos que influyen en la recuperación del sector de la Alameda Antigua de la Avenida Bolognesi, Tacna-2018. La investigación centró su metodología, bajo un enfoque cuantitativo, tipo básico, diseño no experimental de nivel de contraste de hipótesis explicativo observacional, se asume este nivel en razón que establece causa y efecto entre las variables: Factores de la recuperación paisajista. Se aplicó el cuestionario como instrumento de medición; los cuales permitieron recoger información, relacionar y medir las variables de estudio, efectuar las correlaciones y comparaciones correspondientes. La muestra estuvo conformada por 218 arquitectos. Los factores que influyen en la recuperación del sector de la Alameda Antigua de la Avenida Bolognesi, Tacna-2018, son: los conflictos y potencialidades ambientales, el valor social y los mecanismos de gestión.
