“…The large dune Råbjerg Mile on Skagen Odde was the only dune remaining active in Denmark, which also showed an increase in vegetation cover from 29% in 1887 to 94% (Anthonsen et al, 1996). Similarly, most Polish dunes have been stabilised by marram planting and afforestation since the late 19th century (Łabuz et al, 2018), and the only remaining mobile dune (the Łeba Sandbar dune in Figure S1) also showed a 54% reduction in the area of bare sand during 1932-2006 (Peyrat et al, 2009). In the Netherlands, a large extent of mobile dunes have been stabilised by forests and marram since the 1900s (Doody, 2008;Jungerius and Van der Meulen, 1988;Van Dijk, 1992).…”

The mobility of coastal dunes is characterised by bio-geomorphological responses related to change in boundary conditions, particularly sediment supply, wind and vegetation cover, as well as human activities. There remains uncertainty regarding the relative importance of these drivers on dune mobility at a global scale. In this study, trends and dominant drivers of coastal dune mobility are synthesised through the literature review focusing on shifts in dune mobility over the last century (1870–2018). In total, 176 individual dunes, with 55 dunes from the Europe-Mediterranean area, 23 from Africa, 30 from North America, 23 from South America, 20 from Oceania and 23 from Asia, are reviewed in this work. The results show that there is a worldwide trend of dune stabilisation, with 93% (164 out of 176) of the reviewed sites showing a loss of bare sand area due to an increase in vegetation cover and urbanisation expansion. Multiple factors have contributed to the stabilisation process, including (a) land-use change such as the change of traditional farming practises, coastal urbanisation and tourism development; (b) dune stabilisation projects; (c) sediment decline caused by the riverine and coastal constructions; and (d) change in climate (i.e. the decrease in windiness, and the increase in temperature and rainfall) and storms. Our results suggest human intervention played a dominant role in altering dune mobility for most dunes during the past century, while climate and storms are also important drivers, especially for dune sites with limited human activities.

“…Taraxacum officinale) and the Artemisietea vulgaris (e.g. Artemisia vulgaris or Glechoma hederacea) in the upper shore area (Grunewald 2006;Peyrat et al 2009). At beaches with low human pressure, the number of pioneer annuals and herbaceous foredune plants increased according to Grunewald (2006) and Grunewald & Schubert (2007), while the foredune habitat and the related characteristic species disappeared at beaches with higher human pressure (Ciccarelli 2014;Malavasi et al 2014).…”

Questions How do cover, richness and composition of plant species vary according to different levels of beach access? What shifts in plant traits occur along gradients of tourism intensity? What recommendations regarding the sustainable management of Baltic Sea beaches can be proposed? Location Southern Baltic Sea beaches in Germany. Methods In this study, the species composition of vascular plants on beaches with differing accessibility to tourists was analysed at the southwest Baltic Sea coast. In total, 894 vegetation plots were evaluated in order to determine vegetation changes along the sea–inland gradient due to different levels of human accessibility at beaches. Relevés were conducted as repeated transects from the beach ridge to the shore. Shifts in vegetation characteristics due to different levels of tourism access were analysed at the level of plant communities and plant species traits. Results Species richness did not differ significantly between the levels of accessibility. Vegetation cover significantly increased with distance to the shore and was highest in the upper shore area of closed beaches (52.0 ± 2.7%). Corresponding to the increase in beach access, we observed an increase in ruderal species and a decrease in typical beach species of the vegetation class Honckenyo‐Elymetea. Tourism access and distance to the shoreline had a decisive influence on the distribution of plants with selected plant traits. In particular, at accessible sites, a loss of plants with leaves having high scleromorphy was recorded. Conclusions Increased beach access results in a loss of typical beach plant species. Changes in vegetation characteristics are considered to alter the function of the beach ecosystem. Based on these results, we derived spatially differentiated management measures for excluding the most sensitive beach areas from tourism.

Though Muckersie and Shepherd [38] used a rate of 5 m yr −1 , dune movement on the Manawat ū coast can be much more dynamic, with 50-80 m yr −1 reported by Hesp [21], while Holland [27] reported 1200 m yr −1 for low dunes migrating across pasture, physiognomically similar to our wetland turf vegetation.…”

“…However, in some places, coasts are prograding, e.g., Magheramore, Ireland [4], Wadden Sea, Denmark [16], Humboldt Bay, California, U.S.A. [46], and Whatipu Beach, New Zealand [43], which is commonly a response to regionally increased sediment supply. Progradation also affects dune slack wetlands by changing their proximity to the coast [20,54], isolating them in space as relict features [43], or hastening their succession to more complex vegetation stages [12,15,45], or even to their demise [4,39,46]. Such dynamics raise the question of whether coasts need to be prograding for dune slack wetlands to actually form [5].…”

Dunelands are one of the most dynamic environments on Earth, which greatly hinders their conservation and management. In the dune slacks along the Manawatū coast, New Zealand, lies a zone of small, temporary, freshwater wetlands that host early seral communities of rare turf plants. Analysis of historical aerial photos allowed determination of coastline movement, distance of the wetlands from the coast, and wetland movements through time. Study sites were around the coastal settlements of Tangimoana and Foxton Beach, both having major rivers debouching nearby, and Himatangi, amongst stabilising exotic pine plantations. The coastline is prograding (with seaward movement) generally by 0.7–1 m yr−1, but is more variable closer to river mouths, with episodes of movement of up to 15 m yr−1. Wetlands occur 200–400 m behind the strandline, are closer to the coast at Foxton Beach, and furthest away at Himatangi. Wetlands wobble in their position at 5.2 m yr−1 but migrate inland at an average of 2.7 m yr−1. Wetland size appears unrelated to rainfall, but may be related positively to coastal progradation rate, to which wetland movement is negatively related. Near the major rivers, dunes are less stable, and wetlands can be impacted both positively and negatively. Wetland existence and movement is balanced between stability and dynamism on the coast, and management will need to be proactive to maintain environments for early successional turfs.
