“…become wetter). In the UK, Curreli et al (2013) showed that differences in mean water table level of only 20 cm differentiate between dune slack vegetation communities, with 40 cm separating the wettest and the driest communities. Based on predictions of falling groundwater levels for a west coast UK dune system (Clarke and Sanitwong Na Ayutthaya 2010), although outside the area of this assessment, Curreli et al (2013) suggested that climate change may alter what are currently wet slack communities to dry slack or even dry dune grassland by the 2080s (Fig.…”

North Sea Region Climate Change Assessment

This chapter examines the impacts of climate change on the natural coastal ecosystems in the North Sea region. These comprise sandy shores and dunes and salt marshes in estuaries and along the coast. The chapter starts by describing the characteristic geomorphological features of these systems and the importance of sediment transport. Consideration is then given to the role of bioengineering organisms in feedback relationships with substrate, how changes in physical conditions such as embankments affect coastal systems, and the effects of livestock. The effects of climate change-principally accelerated sea-level rise, and changes in the wind climate, temperature and precipitation-on these factors affecting coastal ecosystems are then discussed. Although the focus of this chapter is on the interaction of abiotic conditions and the vegetation, the potential impacts of climate change on the distribution of plant species and on birds breeding in salt marshes is also addressed. Climate impacts on birds, mammals and fish species are covered in other chapters.

“…The dominant habitat at the site is Fixed dunes with herbaceous vegetation (Natura code 2130), the older parts of which show succession towards a de-calcified dune grassland containing acidophile species including Cladonia species and other lichens, which comprise special interest features of the site (Plassmann et al, 2010). Annual rainfall is 850 mm (Curreli et al, 2013) and the prevailing wind direction is from the south west.…”

Abstract:This study investigated potential ammonia impacts on a sand dune nature reserve 600 m upwind of an intensive poultry unit. Ammonia concentrations and total nitrogen deposition were measured over a calendar year. A series of ammonia and nitrogen exposure experiments using dune grassland species were conducted in controlled manipulations and in the field.Ammonia emissions from the intensive poultry unit were detected up to 2.8 km upwind, contributing to exceedance of critical levels of ammonia 800 m upwind and exceedance of critical loads of nitrogen 2.8 km upwind. Emissions contributed 30% of the total N load in parts of the upwind conservation site. In the nitrogen exposure experiments, plants showed elevated tissue nitrogen contents, and responded to ammonia concentrations and nitrogen deposition loads observed in the conservation site by increasing biomass. Estimated longterm impacts suggest an increase in the soil carbon pool of 9% over a 50-year timescale.

“…Other issues of concern are the projected changes in 375 hydrological regimes, due to climate change, from wet dune slack regimes to dry grassland regimes 376 (Curreli et al, 2012). This is likely to increase the mineralisation of organic matter, such that the desired 377 low nitrogen and phosphorus conditions are not preserved (Lammerts and Grootjans, 1997), which will 378 further exacerbate the eutrophication issue.…”

They are subject to many pressures including climate change, 25 land use change and eutrophication. Despite their biological importance and the threats facing them, 26 the hydrological and nutrient parameters that influence their soil properties and biodiversity are poorly 27 understood and there have been no empirical studies to date testing for biological effects in dune 28Manuscript for Science of the total environment ACCEPTED 2 systems resulting from groundwater nutrients at low concentrations. In this study we examined the 29 impact of groundwater nutrients on water chemistry, soil chemistry and vegetation composition of dune 30 slacks at three distance classes (0-150 m, 150-300 m, 300-450 m) away from known (off-site) nutrient 31 sources at Aberffraw dunes in North Wales, whilst controlling for differences in water- (Provoost et al., 2011;Jones et al. 2011; Beaumont et 56 al. 2014). With regard to the latter; nutrients from atmospheric deposition have increased dramatically 57 from their pre-industrial levels of 2 -6 kg N ha -1 yr -1 (Fowler, 2004). As a consequence, the critical load 58 defined for dune slacks, 10-15kg N ha -1 yr -1 (Bobbink and Hettelingh, 2011), is exceeded across much 59Manuscript for Science of the total environment ACCEPTED 3 of Europe. While the effects of atmospheric deposition have received recent attention in dry dune 60 habitats (Plassmann et al., 2009; Remke et al. 2009;Jones et al. 2013), relatively little attention has 61 been given to the impact of other sources of nutrients in dune wetlands, indeed in wetlands in general, 62 and the issue of groundwater or surface water-derived nutrients is not explicitly considered within 63 atmospheric critical loads frameworks. In dune systems that are not isolated hydrologically from 64 surrounding groundwater, there is the potential for nutrient inputs to these habitats from agricultural and 65 other sources via groundwater to add to the nutrient load already received from atmospheric deposition. grasslands (Heil and Diemont, 1983). However, in dune slacks there is still relatively little empirical 82 evidence of nutrient impacts either from atmospheric deposition or from other sources, especially at 83 realistic N loads. One of the few studies, using high nutrient loads on dune vegetation at Braunton 84 Burrows demonstrated that Agrostis stolonifera dominated a dune slack following surface additions of N 85 and P (Willis, 1963). 86 87 Dune slack water tables tend to be at their highest in winter and fall in the summer m...
