BEACH AND DUNE NETWORK
Welcome to the BEACH and DUNE NETWORK - Germany
Coastal dunes are one of the most threatened habitats in Europe. They offer habitats for various, often specialised animals and plants; and the unique landscape constitute an important service for human well-being. Human pressure, landscape use and the nature values result in conflicts of interests.
Aims of the Coastal network, to

The State of Coastal Dunes of the Atlantic Biogeographical Region 2020
John Houston, GB, houstonjohn37(at)gmail.com
Note: This summary is derived from the Article 17 data published by the European Environment Agency in 2020. The information was correct at the time of writing in October 2020 but subsequent edits may have changed some information and web links may have changed.
State of nature in the EU 2020
The European Environment Agency published the report State of nature in the EU on 19th October 2020. The report is an analysis of the data provided by Member States reporting under the nature directives 2013-2018. For Habitats Directive habitats and species the detailed information by member state and biogeographical region is published in a series of dashboards and the Article 17 web-tool. These can be used to check the current status and trends of habitats and species by Member State, by biogeographic region, by habitat type or species and to compare this information with reports from 2001-2006 and 2007-2012. Links in the Article 17 web-tool give access to Member State reports reported by biogeographical region.
Across all habitat groups, dunes (21 coastal and inland habitat types), along with bogs, mires and fens, have the highest percentage (>50%) of bad assessments and a low number of good assessments. These ‘dune habitats’ include the 10 habitats making up the Habitats Directive sub-group Sea dunes of the Atlantic, North Sea and Baltic coast, 7 habitats in Sea dunes of the Mediterranean coast and 4 habitats in Inland dunes, old and decalcified.
© EEA 2020
According to Member States assessments the total area of all Annex I dune habitats (coastal and inland) is 9,200 km2, the smallest area of any habitat group. Compare this, for example, to the reported 406,000 km2 of coastal habitats. As a consequence any proposed restoration targets for coastal dunes are relatively small in the big picture. Working together, however, e.g. through the Natura 2000 Biogeographical Process, will help to ensure that habitat restoration and habitat creation opportunities are promoted.
Coastal dunes in the Atlantic biogeographical region
This note is derived from the information from the Article 17 reports for the Member States in the Atlantic Biogeographical Region (i.e. Denmark, Germany, The Netherlands, Belgium, France, Spain, Portugal, UK and Ireland). Only The Netherlands, Belgium, UK and Ireland lie wholly within the Atlantic region. The EEA State of nature report 2020 includes data for the UK which was still a member of the EU in the reporting period. The UK, however, will no longer take part in future Article 17 reporting, although information on habitat and species status will continue to be monitored. This, therefore, will be the last EEA report which presents information from the nine countries in the Atlantic biogeographical region.
The Atlantic biogeographical region holds the largest area of coastal dune habitat in EU-28 (43%) but also has the lowest percentage of habitat in good condition (28%).
The main set of Habitats Directive Annex I coastal dune habitats of the Atlantic biogeographical region are in the sub-group of the Interpretation Manual of EU Habitats ‘Sea Dunes of the Atlantic, North Sea and Baltic coast’, i.e:
2110 Embryonic shifting dunes
2120 Shifting dunes along the shoreline with Ammophila arenaria (white dunes)
2130* Fixed coastal dunes with herbaceous vegetation (grey dunes)
2140* Decalcified fixed dunes with Empetrum nigrum
2150* Atlantic decalcified fixed dunes (Calluno-Ulicetea)
2160 Dunes with Hippophae rhamnoides
2170 Dunes with Salix repens ssp. argentea (Salicion arenariae)
2180 Wooded dunes of the Atlantic, Continental and Boreal Region
2190 Humid dune slacks
21A0 Machairs (* in Ireland)
* Signifies that the habitat is a priority habitat
The overall distribution and condition of these habitats in Atlantic biogeographical region (i.e. the total for nine Member States) is:
|Habitat||Habitat code||Area (ha)||Overall assessment|
|Embryonic shifting dunes||2110||5,456||U1 poor|
|Shifting dunes along the shoreline with Ammophila arenaria (white dunes)||2120||28,232||U1 poor|
|Fixed coastal dunes with herbaceous vegetation (grey dunes)||2130*||117,321||U2 bad|
|Decalcified fixed dunes with Empetrum nigrum||2140*||23,377||U1 poor|
|Atlantic decalcified fixed dunes (Calluno-Ulicetea)||2150*||2,271||U2 bad|
|Dunes with Hippophae rhamnoides||2160||14,439||FV good|
|Dunes with Salix repens ssp. argentea (Salicion arenariae)||2170||4,136||U1 poor|
|Wooded dunes of the Atlantic, Continental and Boreal Region||2180||129,807||U1 poor|
|Humid dune slacks||2190||14,751||U2 bad|
|Machairs (* in Ireland)||21A0||14,768||U1 poor|
|Total for Atlantic region||354,558|
FV= Favourable; U1 = Unfavourable-inadequate; U2 = unfavourable-bad

LIFE-Projects with focus on dunes...
DUNIAS: starting soon
The aim of the project is to restore important coastal and archipelagic habitats, such as sun-lihgt environments, coastal meadows, herb-rich forests and wooded pastures. The CoastNetLIFE Project aims to improve the conservation status of Natura2000 sites along the Baltic coastal zone of Finland and Estonia. The aim is to create a functional network of coastal habitats. The main focus is on open and semi-open environments that are typical of the coastal area. The project restores environments that are now in poor condition and supplement the network with new areas.
Dynamic Dunescapes is a project restoring sand dunes across England and Wales for the benefit of people, communities and threatened dune wildlife. This project will restore nine key dune areas, from Cornwall to Cumbria. These key areas include 34 individual dune systems and cover up to 7,000 hectares. Natural England, Plantlife, National Trust, Natural Resources Wales, Wildlife Trusts, Cornwall Wildlife Trust, Lincolnshire Wildlife Trust and Cumbria Wildlife Trust are working in partnership to deliver this ambitious project. Running until 2023, this project will: restore sand dunes by carrying out pioneering conservation actions; raise awareness that healthy dunes need moving sand; encourage more people to explore, enjoy, and help protect the dunes through a program of innovative public engagement and citizen science events and activities; develop skills to manage dunes better, both now and in the future.

Dynamic Dune Management in Practise-2021-
Luc Geelen, Waternet, NL
Netherlands Center for Coastal Research (a cooperation of the coastal knowledge institutes) organized a theme in September. The NCK theme day 'Dynamic dune management in practice' shared and discussed the latest insights into dynamic dune management from recent projects such as Spanjaards Duin, Hondsbossche Duinen and Prins Hendrik Zanddijk. One of the biggest challenges in these projects is the balance between allowing dynamics for nature and flood risk management functions. Because these projects have created dune areas from scratch, they require an adaptive approach. The value of these types of projects for coastal research in general and the Dutch coastal landscape or specifically N2000 dune nature in particular was discussed. The location and the field visit zoomed in on the development of Spanjaards Duin! In the winter of late 2008 - early 2009 Spanjaards Duin was constructed on the coastal stretch near 's Gravezande (ZH) as a compensation for Port development in Rotterdam Maasvlakte 2. For the first time, a dune area was created with sea nourishment sand that was to provide space for high-quality gray dune and dune valleys. vegetation within a predetermined time frame of 25 years. The legal compensation project for Maasvlakte 2, in other words, whereby dune values that would be lost in Voorne had to be compensated in development of Spanjaards Duin: H2190 and H2130 in specifically imposed hectares, verifiable to be achieved in 2032!
There is therefore policy/administrative pressure from the Port Authority who demonstrably want to achieve the nature compensation objective based on their specific interests. There is therefore quite a bit of monitoring to assess progress towards goals. Spanjaards Duin's project and management was summarized as dynamic if possible and adaptive if necessary
Adaptive management appeared to be necessary to achieve a suitable starting situation for moist dune valley vegetation (H2190).
- hydrology is not sufficiently well predicted in advance (also a problem with the sand engine) and the large amount of shells in the intended valley caused “dessert pavement”, which blocked the drift to groundwater level. : so excavators have been working towards ground level.
- because H2190 and H2130 are a strict target, blow-through holes in the new foredune were closed to prevent the valley from becoming overblown with sand.
- vegetation development has been stimulated with the input of hay from locations with “target habitat” ie the Meijendel and Kennemerstrand valleys. In places where this clipping was introduced, you clearly saw accelerated succession with more target species present
- increase in sea buckthorn is going very fast and Zuid Hollands Landschap is pulling out sea buckthorn with volunteers. Follow-up management may have to intensify in the coming years (nitrogen input is high there!)
Hay (with seed) has also been introduced for acceleration H2130 and also a reduction in dynamics (H2120!)
It was an interesting discussion about the feasibility of nature goals with the strictness of the habitat objectives in relation to the desired dynamics in the context of coastal management.
Dunescapes Sand Dune Manager's Handbook-2021-
The Dynamic Dunescapes partners have developed a comprehensive handbook discussing the wide range of dune management options available to address the issues faced by coastal sand dune systems, including overstabilisation and invasive species. Management interventions detailed include notches, grazing, turf-stripping and scrub clearance. This handbook is designed to be a useful, in-depth resource for sand dune site managers, and aims to keep our management techniques up to date for the needs of dune conservation in a variety of situations.

DUNEA, The Netherlands
DUNEA has been fighting the effects of nitrogen deposition in the areas managed for over 30 years. We do this with nature restoration projects and nitrogen-related management activities, such as: turf cutting, mowing and grazing. This has cost about 4 million euros in the past 10 years.
Our research into the effects of grazing did not prove that too much measures were taken. That is why we have switched to summer and winter grazing, for example. So you cannot 'manage away' the effects of nitrogen indefinitely. Reducing emissions is the only sustainable path to natural recovery.

Sandrine Aubié, EUCC-France
Jean Favennec published about the management strategy of the coastal strip in France. This manuscript traces the development of management strategies since the 1960s (in French).
In 2011 started a pilot project: the Sand Motor. An artificial sandbank, a significant boost for innovative coastline maintenance and a perfect example of Building with Nature. Thanks to the influence of the wind and the sea currents, the Sand Motor has now grown into a beautiful nature reserve and recreational area. Its development is being closely followed and is receiving a great deal of international attention.
Ten years of research and special collaborations have resulted in an innovative way to maintain the coastal area, new possibilities for the surroundings and a wealth of knowledge. A unique connection between nature, science and society.

ENDURE is an INTERREG Two Seas project 2014-2020 testing ways to make our sand dunes more resilient. www.endure.eu.com.
The project will look at establishing sand dunes as adaptive, living sea defences. Many traditional concrete sea defences are old and failing and can be expensive or challenging to maintain. Natural ecosystems can provide better, more resilient protection: sand dunes naturally migrate, flex and evolve to create a self-replenishing barrier to the sea.
However, this adaptive ability is often compromised by poor and/or reactive management that deals with the aftermath of erosion or flooding events, rather than preventing these events from happening in the first place.
Over three years the project partnership will work collaboratively using the best of cutting-edge science, design and innovation, to develop a coastline with more natural resilience to erosion, flooding and rising sea levels.

Storms and high tides since years bring a lot of litter to the beach. Is there any change in the amount and the composition of the litter?
Embryonic dunes with Honckenya peploides, measured in surface and height since 2017, increase. Is there any relation to storms, growing beaches, tourism?
New plant species arrived at the Polish Coast, e.g. Elymus farctus is spreading. How is the relation to geomorphology and climate change?
Well known dune grasses occur, Ammophila arenaria, x Calammophila baltica, Calamagrostis epigejos. But along the Polish Coast a taxon with a much larger flowering stand occur. An answer to the systematic is still missing.

Dyke,P. (2020) Sand dunes, mobility and cultural heritage. A report to the National Trust. 125 pp.
Research about sand dunes, their mobility (past, present, and future), and impacts on cultural heritage from the Atlantic coast of South West France, to the Low Countries, around the UK and the island of Ireland.
The research theme centred on the idea that dune landscapes are rich in cultural heritage, yet their inherent dynamism and potentially increased future mobility, driven by climate change, may present new challenges for dune managers and dune stakeholders - challenges that need to be better understood.
Through conversations with dune managers, academics, and dune stakeholders it became clear that cultural heritage stories and associations offer a way to engage with and capture public interest in dune landscapes. This approach is perhaps more easily accessible than the often technical narratives of the natural sciences.
In addition to cataloguing the cultural heritage interests, also researched is the topic of physical dune mobility based on historic, contemporary, and projected future dune behaviour. Over the coming decades we will need to get used to the idea of shorelines changing rapidly in response to climate change. Dune coasts are no exception, and indeed we are already seeing evidence of this during storm events with beach lowering and cutting back of foredune features.
The impact of climate change on dune landscapes is however likely to be mixed. On the one hand dune fronts and beaches are likely to become increasingly mobilised in response to storm events, and correspondingly the cultural heritage features within this zone will be impacted first and worst. In marked contrast the dune hinterlands are likely to maintain their stability, due to the protective mantle of sand binding vegetation and processes of ecological succession, meaning that any onset of greater mobility could be delayed for decades. There will be exceptions to more stable dune hinterlands where for example mobility already exists, such as at Formby on the Sefton coast.
Whilst the impacts of climate change at the coast may vary, what is certain is that at a site-based scale the likely impacts will need to be taken into account by those managing sand dunes, for nature, for cultural heritage, for recreation, or as sea defence structures. For the Trust this will mean committing resources to understand and record change on beaches and in foredunes, not just in reaction to individual storm events but as part of a regular regime of monitoring that provides an evidence base to show how sand dunes, and their mobility, are impacting on cultural heritage over time. To this end offering the following recommendations:
1. Recognise that cultural heritage features associated with sand dunes are of significant value in providing a tangible way to better understand shoreline change and engage with stakeholders.
2. Pursue a proactive programme of monitoring coastal change on sand dune sites in partnership with relevant agencies and research establishments with a specific emphasis on historic environment interests, adopting the SCAPE model from Scotland, and as appropriate linking to region and country Coastal Monitoring Observatories.
3. Put in place a more fleet-of-foot approach to achieving preservation by record that can be rapidly mobilised by having in place ‘call-out contracts’ to enable additional external expert help to be deployed in response to a storm event.
4. Review Trust sand dune locations to determine where, through acquisition or partnership working, it is possible to provide accommodation space for dune evolution inland or along the shoreline.
5. Contribute to the Dynamic Dunescapes project workstream ‘Sand dune management handbook’ to develop contemporary guidance for site managers that includes geomorphological, historic, and natural environment interests, climate change impacts and access issues.
6. Maintain and/or establish broad ranging sand dune management research partnerships with Universities and other research bodies for key Trust sand dune locations.

This document sets out Natural England’s view on Favourable Conservation Status (FCS) for coastal sand dunes in England. FCS is defined in terms of three parameters: natural range and distribution, area, and structure and function attributes.
Section 2 provides the summary definition of FCS in England. Section 3 covers contextual information, Section 4 the metrics used and Section 5 describes the evidence considered when defining FCS for each of the three parameters. Section 6 sets out the conclusions on favourable values for each of the three parameters. Annex 3 lists the references.
This document does not include any action planning, or describe actions, to achieve or maintain FCS. These will be presented separately, for example within strategy documents. The guidance document Defining Favourable Conservation Status in England describes the Natural England approach to defining FCS.

From spring 2021 there will no longer be cleaning machines on a two-kilometer stretch of beach near Ouddorp. Any seaweed that remains is good for the birds that nest on the beach.
The stretch of beach between the lighthouse and De Vrijheid is the first official green beach of Goeree-Overflakkee. From now on, rubbish will be removed manually by a group of volunteers. The seaweed just remains, allowing all kinds of small life to grow.
The beach had become a blank sandbox in recent years, all life was gone. Machines clean the beach. As a result, birds, such as the ringed plover that breeds on the Ouddorp beach, cannot find food.
Agreements have been made with the municipality to better protect nature. Not only does cleaning no longer take place, but it has also been determined that cars (from the water board, municipality, ...) will all run on one track from now on. Signs will be placed to explain to visitors why a green beach is important and why dogs, for example, are not allowed to run loose during the breeding season.

Project: COASTAL CHANGE AND GOLF LINKS RESEARCH PROJECT-2020-
Paul Rooney, Hope University, Liverpool, Great Britain
The ‘Coastal Change and Golf Links Research Project’ is established to identify current levels of coastal management understanding and engagement across links and cliff top golf courses.
The study aims to establish the levels of awareness, understanding and engagement of coastal change that are held by the relevant golf courses, national governing bodies for golf, professional golf associations and key stakeholders. The research will provide a clear account of overall levels of coastal change awareness and support this with a consideration and appraisal of existing management measures.
At the conclusion of the project the findings will demonstrate how prepared golf clubs are across the British Isles for the challenges that lie ahead and how the more proactive golf clubs are providing sustainable coastal management within their course management.

In the context of Natura 2000, rare species and vegetation types in the Netherlands are protected in a European perspective. This report (in Dutch with English summary) focuses on the H2130 Grey dunes Habitat type, for which the Netherlands has great responsibility within the EU.
Aeolian dynamics was and is a very important precondition for biodiversity of the coastal dunes. Aeolian dynamics ensure both rejuvenation of the soil, pioneering situations and succession to new dune grasslands. It is assumed that mild dynamics in the form of small-scale spraying can greatly contribute to the quality of dune grasslands. Due to changes in the use and management of coastal dunes, the dispersal dynamics have decreased in many dune areas in the past century. This has major consequences for biodiversity and therefore also the quality of Gray dunes.
In the Nitrogen Programmatic Approach (PAS) great importance is attached to the role of aeolian dynamics within the coastal dune landscape. In the PAS recovery strategy, the reactivation of spraying fresh sand is considered to be a proven measure for the development and / or conservation of habitat type H2130 Grey dunes (lime-rich as well as lime-poor), with which negative effects of nitrogen deposition can be mitigated. Within the PAS there are extensive interventions in the pipeline in he Netherlands to bring back aeolian dynamics on a particularly small scale within the dune landscape with the aim of improving the preconditions for Grey dunes. So there is an enormous, urgent need for practically applicable knowledge on this subject.
The purpose of this research is to find out what the most important factors are that control the development and the aeolian life of small-scale blowouts in coastal dunes. In addition, the influence of small-scale spraying of lime and sand in time and space on the maintenance ('ecological lifespan') of diversity of system-characteristic plants and animals in both limestone-rich and limestone poor dunes has been determined.
Finally, this knowledge has been translated into practical management tools for the maintenance, restoration and new development of Grey dunes by reactivating small blowouts.
The aim of the Knowledge Network for Development and Management of Nature Quality (OBN) is to develop, disseminate and utilize knowledge for area managers about nature restoration, Natura 2000, PAS, habitat management approaches and the development of new nature. A number of specific management recommendations have also been published on the application of small-scale dynamics.

Jianhui Du & Patrick Hesp recently published a review article on Salt Spray Distribution and Its Impact on Vegetation Zonation on Coastal Dunes. Salt spray is, after sand deposition, often considered the second dominant factor contributing to vegetation zonation in coastal dunes. Salt Spray mainly originates from the bursting of bubbles in breaking waves, is carried by wind, intercepted by coastal dunes and plants, and redistributed in the sand/soil after precipitation. In this paper, the literature on salt spray distribution and impact on dune plants are reviewed.

In their article “Geomorphologic characteristics and evolution of managed dunes on the South West Coast of France” Victor Bossard and Alexandre Nicolae Lerma describe a geomorphologic classification of foredunes along the 230 km of the Aquitaine coast and they analyze relations between dune management actions and marine and aeolian driven processes. Summing up management strategies conducted on the Aquitaine coast, three scenarios are generally considered to face the consequences of severe marine erosion. In the light of chronic erosion and relatively low sediment availably dynamics, these scenarios integrate into a stable to receding coast. With further sea level rise over the next decades probably requires extensive new management strategies. And authors promote so-called “controlled dynamic strategy” or guided remobilisation in order to adapt these environments to actual and future pressures.
French coastal dunes of the Côte d’Opale (northern France). Examples of resilient beach-dune systems with mobile foredunes-2020-
Northwards view showing a resilient coastal system: on the left picture, from left to right, 500m-wide sandy beach with ridge-and-runnel morphology, mobile foredune with Ammophila arenaria, partly stabilized older dunes with parabolic landforms and “grey” vegetation cover. These dunes were mobile and directly linked with the beach until the end of the last century. The foredune formed in the last 20 years. On the right picture, typical vegetation of the mobile foredune.
The beach-dune contact may change rapidly, according to the macro-tidal range, and the wave and wind instantaneous climate. A steep sand cliff can form after successive storm events, but it can change in a few months into a concave profile with incipient dunes on the upper beach.
Researches on this coastal section are in progress (CNRS Laboratory of Oceanology and Geosciences, LOG, University of Lille and University of Littoral)
Coastal sand dunes are home to stunning, species-rich ecosystems and provide numerous services to mankind, such as storm protection, opportunities for tourism and production of drinking water. Most coastal sand dunes across Northwest Europe currently experience denser vegetation cover and geomorphological stabilisation, resulting in a rapid decline in biodiversity and loss of important services. Nature managers are therefore increasingly implementing pragmatic nature-based solutions to restore static dunes into dynamic ecosystems.

Restocking is a commonly used practice in wildlife management, and particularly for European wild rabbit (Oryctolagus cuniculus) in France, Portugal and Spain. Many populations are declining, primarily because of habitat destruction and both myxomatosis and rabbit haemorrhagic disease.
Now that the rabbit is not doing well in many coastal dune areas, there are proposals to move rabbits from populations with good density. When the rabbits have completely disappeared, reintroduction may be an option. But improving existing populations with low density earlier may be a better strategy. There are some small experiments in the Netherlands with local reintroduction or addition of rabbits. In addition to a discussion of Dutch projects the OBN project will also deal with a literature study. Experience from management by dune farmers in the 17th century, and the experiences in France and Spain are gathered.
Rabbit breeding sites in the Netherlands
It is instructive to see how the dune farmers (“Duinmeiers”) in former days promoted rabbit populations. In the Netherlands in the 14th century already a system was created in the dunes of open warren "warandes" (breeding and hunting grounds), for commercial keeping of wild rabbits for their meat and fur. Information about their activities we owe Prof. Swaen for the translation of one of the oldest known manuscripts in the Dutch language, dealing with hunting and falconry from ± 1635. In sparsely populated areas of the dune warren the duinmeier made artificial caves with a special drill. He fed the rabbits in the winter with hay, oats and bran or willow prunings. The “Duinmeier” fought predators and birds of prey; which led even to the eradication of the fox in the Dutch dunes.
Experience from France and Spain
In France and Spain, many rabbits have been released or placed for hunting in the past, an estimated thousands per year. Nowadays also rabbits are managed for the conservation of native predators. We see the same management here as with the Dutch duinmeiers: sufficient food, making artificial nests and protection against predators. In Spain people make great efforts to preserve the rabbit as a prey animal for rare predators such as the Iberian Lynx (Lynx pardinus) and the Spanish Imperial Eagle (Aquila adalberti). Improving the habitat turned out to be one positive effect on the rabbit population. In this case was the reduction by burning low shrubs seemed to be effective. Various factors are studied in a large experiment: the season in which the introduction is made, the numbers that are added and the quality of the release area (nutrient-rich and nutrient-poor habitat). Success was measured by survival, the extent to which the rabbits remained in the area and the expected population growth. The highest success was achieved with a low number of released rabbits (40 on 15 ha)
in a nutrient-rich habitat. Placing in the breeding season is unfavorable, because there are many conflicts about mating and nesting during this period, where animals chase or injure each other. But because of considerable lack of knowledge most of current rabbit management programs should be revised to optimize the use of
available resources in the attainment of an effective rabbit density increase.
Letty (2003) has done experiments in France with additions of rabbits. He found a high mortality in the first two weeks and strong dispersion (withdrawal) of the new rabbits. In a population that the researchers followed day by day in the first two days after release 41-51% of rabbits died from predation or stress. And also later predation led to a lower survival than in a population protected against predators. The rabbits settled up to 225 meters from the artificial nests in which they were released. Moreover, the surviving rabbits that were introduces did not take fully part in reproduction.
In summary preliminary results show:
- Additional placement requires a lot of effort and is not always successful.
- A prerequisite for success is the suitability of the habitat.
- Protection against predators for a longer period is necessary.
OBN will provide a more detailed overview in their final report giving the methods and techniques used.

Research include the stugy of the annual rings of Calluna vulgaris plants from Hiddensee, more specifically from two heathlands of different age at the Dünenheide. Collecting plants in groups of three growing next to each other: (1) plants that looked healthy, (2) plants that were dead and (3) plants that were a bit damaged. We replicated this several times across the heathlands. We are trying to find out whether plants died after the 2018 drought or before, and whether the die-back is related to their age and/or the growth of previous years.
In addition, a manipulation experiment was set up in the same area, also in two heatlands of different age. There, rain-out shelters have been built to simulate drought, and vegetation (mainly heather) has been clipped to simulate browsing. I attach a link with further explanations on the experiment:
The project is an Environmental History project focused in the relation between people and coastal dunes.The team combines geologists, historians, geographers and biologists. Covering the last three centuries and using a transdisciplinary approach, our team will travel across borders and centuries to find out who were the pivotal actors that changed the course of history of coastal dunes.

The Netherlands will allocate five billion euros over the next ten years to tackle nitrogen precipitation. In a letter to Minister Schouten and the four coastal provinces, the Duinbehoud Foundation asks to invest primarily in the proper management of nature restoration projects and in the construction of buffers around the nature reserves.
Marc Janssen, biologist and director of the Dune Conservation Foundation, is pleased that money is being released for nature restoration. “Five billion is a significant investment and a step in the right direction. But if it remains that way, nature will still be exposed to too much nitrogen in 2030. Investments are also necessary after 2030, in particular to structurally reduce nitrogen emissions. ”
Originally, the Dutch dune area is nutrient-poor. For centuries, flora and fauna have established their survival strategies for this. Now nitrogen is seriously disrupting the ecosystem. In the Dutch dune areas, this is reflected in an excessive vegetation with shrubs and grasses. As a result, dunes hardly drift and the original species-rich vegetation, birds and insects disappear. Birds find less and less food in overgrown places in the dunes. Animals are also victims.

'In the OBN Knowledge Network, researchers, conservation site managers, universities, consultancies, NGO’s and governmental bodies, such as provinces and water boards, closely cooperate to restore ecosystems and nature reserves. In this network, knowledge and practice intermingle, and science and nature management jointly look for the most effective approaches to enhance sustainable conservation of important ecosystems in the Dutch landscapes. Since 2006 The OBN Knowledge network formulates each 4 to 5 years its mission statement and knowledge agenda which is leading in all OBN related activities. Based on this mission statement, landscape-based ‘Expert Teams’ are working on the development, dissemination and implementation of knowledge on restoration and rehabilitation of nature reserves, on issues regarding Natura 2000 and the EU Water Framework Directive, as well as on distribution problems of individual species. During the last decade, the OBN Knowlegde Network is also focusing on environmental problems, such as the effects of atmospheric nitrogen deposition, climate change, sea level rise, coastal defense, flood risks, and other changes in the hydrological systems. In these fields of research, the network cooperates with many research institutes.
The Dutch OBN Knowledge Network for Nature Restoration and Management
• is an independent and innovative platform where policy makers, site managers and scientists cooperate in the management and restoration of natural areas;
• it develops and disseminates knowledge to enhance nature quality management and conservation in the Dutch lansdcapes and in the Atlantic Region.'
