“…Nevertheless, trampling activity by beach visitors was determined to be more harmful for plant development than natural stress (Santoro et al 2012), decreasing the diversification of plant populations at beaches (Puijalon et al 2008) and finally hindering prolonged dune development substantially (Hesp et al 2010;Barbier et al 2011). The examined beach plants indicated different resistances to trampling according to their relative biomass.…”

In the last century, increases in human population and beach tourism have affected coastlines worldwide. Resulting pressures on beach ecological systems demand research concerning tolerance of beach plants to disturbance by humans. At three different Baltic Sea beaches, Atriplex prostrata, Honckenya peploides and Crambe maritima were planted and observed while subjected to trampling stress intensities of 0, 1 and 2 footsteps·m −2 ·d −1 . Plant height, leaf growth, number of leaves, chlorophyll content of leaves and fitness of photosystem II were measured at monthly intervals. Survival of plants was documented until the following summer. Linear mixed effect models fit the effects of trampling intensity, time and species on growth, photosynthetic productivity and reproduction of plants. Survival was fitted using general linear mixed models for binomial data. The results indicated that the annual species A. prostrata showed an initial decrease in growth at the first trampling treatment, but no effects on seed weight due to trampling pressure. Honckenya peploides was not affected by trampling. Crambe maritima showed a reduction in growth and survival under any level of trampling pressure. Experimental trampling pressure was compared to observed trampling intensities at beaches with low visitor frequency, which was ascertained to be between 3 and 8 footsteps·m −2 ·d −1 . Because of the greater potential of endangerment for C. maritima, we suggest that nature conservation focus on reducing human trampling on the upper beach area, e.g. by closing this area. This practice would allow tourists continued recreational access to the water as well as to the lower beach area.

“…In situations of rising sea level, beach erosion causes an inland movement of dune habitats but, owing to the existence of man-made barriers, species are no longer able to disperse and grow (Martinez andPsuty, 2004 in Feagin et al, 2005;Martins et al, 2013). And in fact coastal erosion actually impacts about 70% of the world´s beaches (Bird, 1985in Feagin et al, 2005.…”

“…Dune vegetation is adapted to the stressful natural conditions and highly dynamic environment of sandy seashores; however, it is very vulnerable to man-made disturbances such as those connected to trampling (Liddle and Greig-Smith, 1975;Defeo et al, 2009;Acosta et al, 2013 Hesp et al, 2010). On the other hand a permanent loss of vegetation cover may occur in cases of high intensity of trampling.…”

“…On the other hand a permanent loss of vegetation cover may occur in cases of high intensity of trampling. That is, trampling intensity has a profound influence on the establishment of bare ground (Hesp et al, 2010). The destruction of plants that trap and hold sand particles exposes the underlying sand to the onshore wind, promoting the development of breaches, called blowouts.…”

Coastal dunes constitute complex interface ecosystems between the land and sea, providing important ecological and socio-economic services like coastal protection, recreation, regulation, food supply and biodiversity. They are characterized by high ecological diversity and also by extremely specialized and endemic species. Coastal areas, because of their position between land and sea, are attractive for many human activities. Unfortunately coastal systems have had a long history of exploitation and mismanagement.

“…segundo Carter (1998) e Hesp et al (2010) as cristas de duna são elementos morfológicos muito vulneráveis ao pisoteio, uma vez que nestas áreas declivosas e elevadas, a acção do vento e da gravidade favorece a sua degradação, reduzindo a sua resiliência.…”

Resumo -O sistema dunar litoral de Peniche-Baleal tem importância vital na estratégia de desenvolvimento territorial do concelho, concretizada pelo forte investimento nas actividades ligadas ao turismo e lazer. O incremento da acção antrópica directa sobre o sistema dunar, sobretudo pelo pisoteio, preponderante na redução ou eliminação da vegetação dunar, resulta na sua degradação geomorfológica e ecológica. a realização de levantamentos de campo e de seis perfis morfo-ecológicos permite (i) caracterizar a morfologia da frente dunar e do sistema dunar; (ii) identificar os diferentes tipos morfo-ecológicos de duna; (iii) reconhecer a diversidade da vegetação dunar e as principais manchas de vegetação; (iv) determinar as espécies dunares presentes nos diferentes tipos morfo-ecológicos de duna. É possível reconhecer a robustez, a elevada diversidade e o bom estado de conservação da vegetação dunar, sobretudo a sotavento da duna frontal, e um núcleo importante de Armeria welwitschii e Verbascum litigiosum, endemismos lusitanos com estatuto legal de protecção. Palavras -chave:Litoral, sistema dunar, vegetação dunar, degradação antrópica, degradação ecológica.abstract -Morpho-eCologiCal CharaCterization of the peniChe-baleal dune systeM (portuguese west Coast). the Peniche-Baleal coastal dune system has a strategic importance on regional development, marked by considerable investment in tourism and recreational sectors. the increasing human impact on this coastal dune system caused by human trampling tends to modify its geomorphological and ecological degradation, namely sand dune vegetation reduction. the morpho-ecological characterization of the coastal dune system was accomplished by six morpho-ecological profiles as well as data from field surveys that allowed the (i) characterisation of foredune morphology and coastal dune system morphology; (ii) identification of different morpho-ecological coastal dunes types; (iii) identification of sand dune vegetation diversity and main spatial mosaics; (iv) identification of sand dune species of the different morpho-ecological costal dunes types. as a result, sand dune vegetation shows high biodiversity and good conservation recebido: Maio 2012. aceite: fevereiro 2013. 1 investigadora do CeG-iGOt-UL, núcleo sLif -sistemas Litorais e fluviais: Dinâmicas, Mudanças ambientais e Ordenamento do território.
