Abstract(s)
O sistema dunar Cresmina-Guincho é bastante peculiar por pertencer a um sistema
transgressivo, corredor eólico ou headland bypass dunefield, denominado sistema
Guincho-Oitavos, que tem uma importância notável para o património natural. Com o
aumento das atividades costeiras e do turismo balnear, o impacte antrópico no sistema
tem vindo a aumentar consideravelmente, criando adversidades que prejudicam
imensamente os habitats e comunidades florísticas e faunísticas instaladas.
Foi realizada uma análise na área onde se identificaram as associações vegetais
dunares e os habitats a que correspondem, descrevendo-os em termos gerais como se
desenvolveriam num estado primordial. Foi feita uma caracterização das condições das
comunidades na área de estudo, identificando os fatores que impedem a sua progressão e
expansão natural. Foram enumerados vários elementos que prejudicam de uma forma
crítica o sistema dunar, afetando habitats e espécies vegetais presentes no local.
Para atenuar e/ou solucionar os impactes existentes são propostas medidas que
promovam a conservação e preservação do sistema dunar Cresmina-Guincho, assim
como das comunidades vegetais dunares e faunísticas que habitam nesta área.
Todos os elementos apresentados neste trabalho de investigação têm como
objetivo complementar e acrescentar informação a outros trabalhos desenvolvidos neste
âmbito.
The Cresmina-Guincho dune system is quite peculiar because it belongs to a transgressive system, wind corridor or headland bypass dunefield, called Guincho- Oitavos system, which is of remarkable importance for the natural heritage. With the increase of coastal activities and bath tourism, the anthropic impact on the system has been increasing considerably, creating adversities which severely damage the floral and faunal habitats and communities installed. An analysis was carried out in the area where dune plant associations and the corresponding habitats were identified, describing them in general terms how they would develop in a primordial state. A characterization of the conditions of the communities in the area of study was made, identifying the factors that prevent their natural progression and expansion. Several elements have been listed which critically disrupt the dune system, affecting habitats and plant species present on the site. In order to mitigate and/or resolve the existing impacts, measures are proposed to promote the conservation and preservation of the Cresmina-Guincho dune system, as well the dune and faunal vegetable communities that inhabit this area. All the elements presented in this research work aim to complement and add information to other works developed in this area.
