Introduction: Forest and pre-forest fringe communities in the southwest of the Iberian Peninsula are semi-shaded perennial herbs of external fringe and open areas of evergreen or semi-deciduous woodlands and their pre-forestry mantles, linked to the Stachyo lusitanicae-Cheirolophenion sempervirentis suballiance. Objective: To evaluate the chorology, ecological features and floristic circumscription of the forest fringe communities of the southwestern Iberian Peninsula. Materials and methods: Forest fringe communities adscribed to the Stachyo lusitanicae-Cheirolophenion sempervirentis suballiance were analysed, using phytosociological approach (Braun-Blanquet methodology) and numerical analysis (hierarchical cluster analysis). Results and discussion: The statistical and phytosociological analysis of six formerly described associations and the samples of this study lead us to propose a new forest fringe association: Picrido spiniferae-Cynarietum algarbiensis, dominated by Cynara algarbiensis Coss. ex Mariz. This forest fringe community is characteristic of the thermomediterranean to mesomediterranean, lower sub-humid bioclimate and occurs in the potential areas of the Quercus suber L. forests (Lavandulo viridis-Quercetum suberis), mainly in the Monchique Sierran District. Conclusion: The statistical and phytosociological analysis were useful in the evaluation of forest fringe communities in the southwest of the Iberian Peninsula. Regarding the proposal of the new association Picrido spiniferae-Cynarietum algarbiensis, it is important to develop management strategies for the preservation of the endemic C. algarbiensis.

Abstract

Introduction: Forest and pre-forest fringe communities in the southwest of the Iberian Peninsula are semi-shaded perennial herbs of external fringe and open areas of evergreen or semi-deciduous woodlands and their pre-forestry mantles, linked to the Stachyo lusitanicae-Cheirolophenion sempervirentis suballiance. Objective: To evaluate the chorology, ecological features and floristic circumscription of the forest fringe communities of the southwestern Iberian Peninsula. Materials and methods: Forest fringe communities adscribed to the Stachyo lusitanicae-Cheirolophenion sempervirentis suballiance were analysed, using phytosociological approach (Braun-Blanquet methodology) and numerical analysis (hierarchical cluster analysis). Results and discussion: The statistical and phytosociological analysis of six formerly described associations and the samples of this study lead us to propose a new forest fringe association: Picrido spiniferae-Cynarietum algarbiensis, dominated by Cynara algarbiensis Coss. ex Mariz. This forest fringe community is characteristic of the thermomediterranean to mesomediterranean, lower sub-humid bioclimate and occurs in the potential areas of the Quercus suber L. forests (Lavandulo viridis-Quercetum suberis), mainly in the Monchique Sierran District. Conclusion: The statistical and phytosociological analysis were useful in the evaluation of forest fringe communities in the southwest of the Iberian Peninsula. Regarding the proposal of the new association Picrido spiniferae-Cynarietum algarbiensis, it is important to develop management strategies for the preservation of the endemic C. algarbiensis.

Introducción: Las comunidades de orla forestal y preforestal en el suroeste de la península ibérica, formadas por plantas perennes semisombreadas con orla externa, campos abiertos de bosques perennifolios o semicaducifolios y mantos preforestales, están vinculadas a la subalianza Stachyo lusitanicae-Cheirolophenion sempervirentis. Objetivo: Evaluar la corología, las características ecológicas y la circunscripción florística de las comunidades de orla forestal del suroeste de la península ibérica. Materiales y métodos: Las comunidades de orla forestal adscritas a la subalianza Stachyo lusitanicae-Cheirolophenion sempervirentis se analizaron utilizando el enfoque fitosociológico (metodología de Braun-Blanquet) y el análisis numérico (análisis jerárquico de conglomerados). Resultados y discusión: El análisis estadístico y fitosociológico de seis asociaciones ya descritas anteriormente y las propias muestras de esta investigación conllevan a proponer una nueva asociación de orla forestal: Picrido spiniferae-Cynarietum algarbiensis, dominada por Cynara algarbiensis Coss. ex Mariz. Esta comunidad de orla forestal se caracteriza por el bioclima subhúmedo inferior, termomediterráneo a mesomediterráneo y se presenta en las áreas potenciales de los bosques de Quercus suber L. (Lavandulo viridis-Quercetum suberis), principalmente en el distrito Serrano Monchique. Conclusión: El análisis estadístico y fitosociológico fueron útiles en la evaluación de las comunidades de orla forestal del suroeste de la península ibérica. Respecto a la propuesta de la nueva asociación Picrido spiniferae-Cynarietum algarbiensis, es importante el desarrollo de estrategias de manejo para la preservación de la endémica C. algarbiensis.
