Sands of LIFE - SoLIFE
As the Sands of LIFE project draws to a close, we are pleased to announce the publication of our Sand Dunes in Wales booklet, available in English and Welsh.
It is aimed at anyone who wants to know a bit more about the ecology of sand dunes in Wales, the pressures they face and the management they need. Ideal for volunteers, students, teachers, concerned local residents, new members of staff, decision-makers and neighbouring landowners.

Notches in the Dunes really help
- translated from the Dutch, DUINBEHOUD
It sounds contradictory: strengthening dunes by making notches in them! That is what Rijkswaterstaat, water boards and dune managers do from time to time. The planning and work is special, not all notches are the same!
Working with nature
'Dynamic coastal management' is a cornerstone of Dutch coastal safety policy. This is possible by letting nature do its work. For example, dune areas become more robust when sand blows in.
The mostly westerly wind in the Netherlands, which blows directly on large parts of the coast, blows sand from the North Sea into the dunes. Rijkswaterstaat lends a helping hand by spraying extra sand along the coast and onto the beach.
But because the sea strip (the first row of dunes) was fixed and high in many places by planting marram grass or placing sand trapping fences/catch screens, a lot of sand from the sea does not get further than the beach and the first row of dunes.
And then the notches or grooves in the front row of dunes come into play. Notches in the sea strip form smoothly ascending slides along which the wind pushes the sand upwards and blows it further into the dunes over the head of the sea strip.
Scientific research
In recent years, a lot of experience has been gained with this method. Scientific studies confirm the positive effects. They also point out the preconditions: first set clear goals, then carefully plan and execute and closely monitor the effects. Customization! This is how one of the success factors was learned: removing vegetation and roots in the notches to make and keep them smooth.
Is there a risk that the sea will break through the dunes via the inlets and the lower-lying hinterland? Hardly! After all, in many places the sea defense is further inland. A safe margin is built in with the height of the sea strip when the sea level rises. By measuring the height in the notches annually, they do not fall below the minimum level.
And in the longer term, this method actually helps to reduce the risk of the sea reaching the hinterland. The dune area becomes wider thanks to extra sand.
More biodiversity
There is a nice side effect of more new sand in the dunes: the calcareous North Sea sand counteracts acidification of the dune soil. As a result, more different plants and animals that belong to the ‘young’ dunes behind the sea strip are added; more biodiversity! This effect is even stronger due to the construction of blowouts that land managers create for extra drifting. This is necessary because of fewer grazing and digging rabbits.
Making room in the sea strip for wind and sand is another safety measure that has now fully proven its worth.

DuneFront
Dune-by-dike Nature-based Solutions: 'DuneFront' aims to enhance coastal protection and safety by optimizing solutions that make use of a combination of natural elements (dunes) and man-made hard structures (seawalls).
Within the DuneFront project, data is collected and evaluated from 12 different ‘Demonstrator sites’ spread over six different countries. Each of the demonstrators represents a hybrid nature-based solution (NbS) where dunes and hard infrastructure (dikes, groynes) are combined under the primary objective of coastal protection and biodiversity restoration, while also recreation can be facilitated, or aeolian sand nuisance. They targeted dune-in-front-of-dike systems (dunes installed in front of new or existing dikes), but also included structural variants (dike-in-dune) as a reference for alternative designs under different boundary conditions.
The project consortium consists of 18 partners with expertise in various fields. Below, a list of the partners contributing to the project can be found: Universiteit Gent, Katholieke Universiteit Leuven, Vlaams Instituut voor de Zee, Eigen Vermogen Flanders Hydraulics, Agentschap voor Maritieme Dienstverlening en Kust, Jan De Nul nv, Dredging International nv, Universidade do Porto, Universite de Bordeaux, Universite de Perpignan, Universite du Littoral Côte d'Opale, Technische Universiteit Delft, Universiteit Utrecht, Stichting Deltares, Technische Universität Braunschweig, Lunds Universitet, Texas A&M University System, Technische Universität Berlin

Five applications awarded for research about the Wadden Sea
The Netherlands and Germany have invested 15 million euros in five research projects that will study the relation between sediment, ecology, human co-use, flood safety and effective protection and management in the Wadden Sea.
The bilateral German-Dutch research projects will help us gain a better understanding of the complex pressures on the Wadden Sea. They will also pave the road to societal impact by charting options for action and developing strategies for management measures. In addition, the programme is an investment in a new generation of Wadden experts, as well as a new bridge between countries, disciplines, institutes and types of stakeholders. In the next four years, the projects are going to combine a focus on sedimentary dynamics and saltmarsh processes with benthic ecology, terrestrial biology, landscape and legal design. They are all set to improve our current understanding of the Wadden Sea and work towards a systemic view of this wild (eco)system.
The five granted projects:
PaRCA. Pathways for Realising Climate Adaptation in the Wadden Sea
Principal Investigators: Prof. Dr. Christian Winter (Kiel University) & Prof. Dr. Zhengbing Wang (Delft University of Technology)

SAND COAST ST. PETER-ORDING
Germany (Bundesprogramm leben.natur.vielfalt) Protecting and restoring coastal habitats. The sandbanks, salt marshes, dunes and the forest of St. Peter-Ording are unique natural assets and protect the hinterland from floods. Some are part of the Wadden Sea National Park and World Heritage Site, others of a Natura 2000 protected area. However, the natural dynamics of the older dune areas in St. Peter-Ording have been lost due to dyking, forestation and housing development. Introduced species are causing and sea-level rise will cause further distress to the coastal habitats. The aim of the joint project "Sand Coast St. Peter-Ording" is to improve the condition of the coastal landscape and to contribute to adaptation to sea-level rise. It is implemented together with local partners and with accompanying scientific research efforts. Further Information (in German), Questions? projekt(at)sandkueste-spo.de
Short report Symposium "Sand Coast St. Peter-Ording” on the development, protection and management of beach, dunes and forest at the Wadden Sea. 6. September 2023, Dünen-Hus St. Peter-Ording, Germany. Jannes Fröhlich, WWF, DE
The symposium "Sand Coast St. Peter-Ording" took place on 6 September 2023 in St. Peter-Ording, Germany, and offered a comprehensive insight into the development, protection and management of the unique coastal landscape of St. Peter-Ording at and in the Wadden Sea National Park and World Heritage Site. The event had a diverse target group with 74 participants from practice, science, nature conservation and coastal protection in authorities, associations, community and citizenship. An excursion to the project area took place on 5 September. A full report and the presentations (in German) will be published on https://sandkueste-spo.de/ergebnisse/.
What was it about?
After 3 (of 6) years of running the project "Sand Coast St. Peter-Ording", we presented and discussed interim results from the diverse topics of dune nature conservation, forest conversion, coastal protection, geomorphology and nature experience. The exciting programme took a multifaceted look at the coastal landscape of St. Peter-Ording and beyond.
Based on presentations by experts from dune nature conservation and coastal research as well as contributions from the "Sand Coast" project, we addressed the following questions, among others:
What is known about the condition of the dunes on the North Sea coast as well as the nature in St. Peter-Ording?
How is the beach in St. Peter-Ording changing today and in the future?
How stable are the dunes in the face of storm surges and sea-level rise?
Why and how do dunes and forests need to be protected and partly managed? What are the possibilities and limits of mechanical maintenance measures and grazing?
The symposium was organised by the team of the project "Sand Coast St. Peter-Ording": WWF Germany, Wadden Sea Office; University of Kiel, coastal geology and sedimentology; Deich- und Hauptsielverband Eiderstedt (local dike board); Schutzstation Wattenmeer e .V.; Technical University of Braunschweig, Leichtweiß-Institut for Coastal Engineering.
The project is financed by the German Federal Programme on Biodiversity by the Federal Agency for Nature Conservation with funds from the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection, and other sponsors.

DUNIAS: Belgium 2021-2026, Project-Website, EU-LIFE-description
The overall goal of the LIFE DUNIAS project is to fight IAS in the Belgian coastal zone in a structured and concerted way. The project’s specific objectives are to: Eradicate invasive alien plant species in all Flemish coastal dunes; Improve the conservation status of the target habitats by removing the pressure from IAS; Prevent the arrival of new IAS or return of eradicated IAS; Raise awareness with various target groups of the importance to take measures against IAS; Exchange knowledge on IAS distribution and best practices for combating IAS; and Improve an existing early warning system and stimulate volunteers to record IAS observations. Workshop 2022 in the framework of the LIFE DUNIAS project in Belgium (Dune restoration by tackling IAS) occurred to work-out a list of invasive species in coastal dunes.
In May 2022 an expert meeting of IAS- and dune experts took place in Koksijde, Belgium in the context of the LIFE DUNIAS project. Most important outcomes of this workshop were best practices of tackling IAS, a systematic risk assessment of current en future IAS and a horizon scan of IAS in the Atlantic coastal dunes. Horizon scan lists can be found in the resulting report on the pages 37 (overall), 40 (salty habitats), 41 (sandy habitats), and 42 (shrubby habitats). P.44-47 summarizes the horizon scan list per country. A complete risk assessment list can be consulted from p. 156 onwards.
