As paisagens dunares são sistemas de elevado dinamismo, devido à proximidade do mar e
à extrema mobilidade do substrato arenoso e prevê-se que venham a ser severamente
afetadas pelas alterações ambientais globais.
As dunas são depósitos de areia criados por processos eólicos e apresentam uma
vegetação muito característica. Estes depósitos de areia em conjunto com a vegetação
formam uma barreira essencial ao avanço do mar durante as marés altas de águas vivas e
tempestades.
Em Portugal, a degradação dos ecossistemas costeiros é muito preocupante. O problema
das espécies exóticas invasoras agravou-se, aumentando a pressão sobre as plantas
nativas.
Embora este problema não seja o único motivo da degradação dos ecossistemas
costeiros, este trabalho pretende divulgar as plantas dunares da zona costeira de
Matosinhos, sensibilizar para a proteção e conservação das dunas e alertar para o facto de
diversas plantas invasoras rapidamente colonizarem espaços abertos, pondo em causa e
estabilidade dos ecossistemas costeiros.
O conhecimento detalhado destes ecossistemas permitirá a aplicação de processos de
vigilância e monitorização bem como o restauro ecológico de áreas dunares degradadas.
Dune landscapes are highly dynamic systems, due to the proximity of the sea and the extreme mobility of the sandy substrate and we can anticipate that they will be severely affected by the global environmental changes. Dunes are sand deposits created by aeolian processes and present a very characteristic vegetation. These sand deposits together with the vegetation form an essential barrier to the advance of the sea during high tides and storms. In Portugal, the degradation of coastal ecosystems is quite worrying. The problem of invasive exotic species worsened, thus adding the pressure on native plants. This paper seeks to show the dune plants of the coastal zone of Matosinhos, to raise awareness for the protection and conservation of dunes and to alert about invasive plant species that quickly colonize open spaces, undermining stability and coastal ecosystems. Detailed knowledge of these ecosystems will allow the application of surveillance and monitoring procedures, as well as the ecological restoration of degraded dune areas.
