Abstract
QUINTO-CANAS, Ricardo et al. Forest fringe communities of the southwestern Iberian Peninsula. Rev. Chapingo ser. cienc. for. ambient [online]. 2018, vol.24, n.3, pp.415-434. Epub Feb 19, 2021. ISSN 2007-4018. https://doi.org/10.5154/r.rchscfa.2017.12.072.
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.
