Plantas invasoras no sul de Portugal: uma abordagem biogeográfica

Abstract

As espécies invasoras são uma das principais ameaças à biodiversidade causando impactes ecológicos, económicos e nos serviços dos ecossistemas. O conhecimento conjunto da dinâmica das séries de vegetação e da ecologia das plantas invasoras é uma ferramenta útil na recuperação ecológica de áreas invadidas e na prevenção de invasões. Este trabalho tem como objectivo principal averiguar a relação entre a distribuição das plantas invasoras e as comunidades vegetais terrestres do Sul de Portugal. Para tal, fez-se corresponder a distribuição de nove plantas invasoras selecionadas com as séries de vegetação e territórios biogeográficos, em 60 quadrículas com 1 Km2. A Província Lusitana-Andaluza Costeira revelou-se a mais invadida, com predomínio de Acacia dealbata, Acacia longifolia e Opuntia maxima no potencial climatófilo de sobreiral psamófilo; A. longifolia dominou no potencial edafoxerófilo de zimbral de Juniperus turbinata e A. dealbata e Arundo donax no potencial edafo-higrófilo de freixial. Com base nos resultados, estabeleceram-se áreas prioritárias para intervenção; INVASIVE PLANTS IN SOUTHERN PORTUGAL A BIOGEOGRAPHICAL APPROACH Abstract: Invasive species are one of the main threats to biodiversity worldwide and are responsible for negative impacts at ecological, economic and ecosystem services level. Complementarity between vegetation series dynamics and invasive plants ecology knowledge is essential to address ecological restoration and to prevent invasions. The main goal of this work is to investigate the relationship between invasive plants distribution and terrestrial plant communities of Southern Portugal. Fieldwork was conducted in 60 1 Km2 sampling plots and a correspondence was made between nine selected invasive plants and the vegetation series and the biogegraphic units The Andalusian-Lusitanian Coastal province was the most invaded biogeographic unit and revealed the dominance of Acacia dealbata, Acacia longifolia and Opuntia maxima in the cork oak psammophilous series; A. longifolia dominated in the maritime turbinate juniper edapho-xerophilous series and A. dealbata and Arundo donax in the ash edaphohygrophilous groves potential. Based on the results, priority areas for intervention were defined.
