Wadden Sea World Heritage

There is a place where heaven and earth share the same stage! One Wadden Sea. One World Heritage.

There is a place where heaven and earth share the same stage: the Wadden Sea World Heritage! The Wadden Sea is the largest unbroken system of intertidal sands and mud flats. It stretches across 500 km along the Danish, German and Dutch North Sea coast. 10,000 species of flora and fauna call this ever-changing landscape their home. Over 12 million migratory birds pay it a visit on their long trips

along the East Atlantic Flyway, making this wilderness in midst of Europe essential for global biodiversity.

Meet the Herring or Clupea harengus. There are around 200 species in the herring family, including sardines, anchovies, and anchoveta. One-third of all fish caught globally belong to this family.

After the Dutch IJsselmeer was dammed, the local herring stock died out – and with it, the bottlenose dolphin population in the area.

Weirdly, Herring maintain contact in their schools acoustically by releasing air bubbles from their anuses. Maybe not something you want to try out during family dinner.

The Wadden Sea World Heritage Site is an important nursery for herring. Juveniles find optimal conditions to grow before migrating into the open North Sea. Thus, the Wadden Sea plays a major role in maintaining herring populations.

Today we celebrate World Salt Marsh Day! What's so special about saltmarsh, you say? As well as being incredible biodiversity boosters, saltmarshes can capture carbon up to 40 times faster than forests, absorb the energy of the tides – protecting manmade sea defences behind them – and give people a beautiful place to get close to nature. More than enough reasons to protect the salt marshes we have and restore the ones we've lost.

Meet the American razor shell or Ensis leei. Originally from American waters, the species was probably introduced to the North Sea in the 1970s via ballast water from ships. It is now abundant in the Wadden Sea. Some sea and shorebird species have learned to use it as a food source. Fun fact: Razor shells can swim and jump underwater!

In the Wadden Sea World Heritage Site, the main goal is to allow natural processes to proceed as undisturbed as possible and to preserve native biodiversity. The introduction of invasive species such as the American razor shell conflicts with this objective.

The birds made Esbjerg – and so have more than 200 Wadden Sea friends. Here, we discussed our shared UNESCO World Heritage Site – the Wadden Sea – how it is doing and what we can do to better protect it together. The three states, Denmark, Germany, and the Netherlands reaffirmed their commitment to protect the Wadden Sea – together.

Three birds on their way to Esbjerg – what are they doing there? From 27 to 29 May, it will be the site of the Trilateral Governmental Conference. There, Denmark, Germany and the Netherlands will discuss the next years of their cooperation on the protection of the Wadden Sea – first initiated in 1978, almost 50 years ago! Three actors connected by a shared UNESCO World Heritage Site: the Wadden Sea. But what exactly will be discussed there? We’ll be covering the event in our story, where we’ll share more details. Stay tuned!

Tre fugle på vej mod Esbjerg – hvad mon de skal der? 27.-29. maj er byen vært for den trilaterale regeringskonference. Her vil Danmark, Tyskland og Nederlandene drøfte de kommende års samarbejde om beskyttelsen af Vadehavet – et samarbejde, der blev indledt i 1978, for næsten 50 år siden! Tre lande forbundet af et fælles UNESCO-verdensarvssted: Vadehavet. Men hvad vil der egentlig blive drøftet der? Vi dækker begivenheden i vores story i næste uge. Følg med her!

Drei Vögel auf dem Weg nach Esbjerg – was haben die denn da verloren? Vom 27. Bis zum 29. Mai findet dort die Trilaterale Regierungskonferenz statt. Dabei setzen sich Dänemark, Deutschland und die Niederlande zusammen, um die nächsten Jahre ihrer seit 1978 laufenden Kooperation zum Schutz des Wattenmeeres zu besprechen. Drei Akteure, verbunden durch das Wattenmeer, ein gemeinsames UNESCO-Weltnaturerbe. Aber was genau wird dort eigentlich besprochen? Wir begleiten die Veranstaltung in der Story. Mehr verraten wir euch dann. Seid gespannt!

Meet the Hooknose or Agonus cataphractus, often found on the seabed among stones. The name Agonus cataphractus roughly means “armoured jointless one”, referencing the fish’s distinctive, armoured body. Its resemblance to the sturgeon is coincidental and not due to “primitive” evolutionary traits.

The hooknose is a sedentary fish in the underwater world of the Wadden Sea World Heritage Site. It spends most of its life in coastal zones, demonstrating how valuable the Wadden Sea is as a permanent habitat for specialised species.

When was the last time you strolled along the dunes of the Wadden Sea? These rolling hills of sand are a charming mix of soft, fluffy peaks and gentle valleys. The sea breeze blows through the fragile grasses that top the dunes, making them dance and sway. It's a whimsical sight that will make you feel like you're in a world of your own. And you never know! Maybe as you explore the dunes, you might even come across some of the Wadden Sea's friendly inhabitants. So, grab your walking shoes and get on the next marked dune path. You won't be disappointed!

Meet the Baltic tellin or Macoma baltica. It comes in pink, white and yellow. Between 200 and 2,000 individuals can be found per square metre of mudflat. The tellin prefers cold conditions: it only grows and filters at temperatures below 15 °C and can survive frost.

The Baltic tellin is found in large numbers in the Wadden Sea World Heritage Site and, like the common cockle, reflects the high animal biomass and short food chains of this dynamic ecosystem. As a key food source for many coastal birds, it plays a central role in the Wadden Sea's ecological network.

Every bird counts – your observations matter! 🐦🌍

On this Saturday's World Migratory Bird Day (WMBD), we celebrate the power of community science. From the Wadden Sea as key feeding and resting site to flyways across the globe, every sighting helps protect migratory birds and their habitats. Join in, look up, and be part of the story of the flyways. 💙

There are many tools to help you identify what you see and researcher collect data – here are a few: Beachexplorer, Merlin Bird ID, Obsidentify

Meet the Plaice or Pleuronectes platessa are also known as "golden flounder" because of their orange spots. Plaice skin was once used to produce a fine leather. Historically, plaice lived up to 50 years, weighed up to 7 kg, and reached nearly 1 metre; today, due to fishing pressure, they rarely live beyond five years.

The Wadden Sea World Heritage Site is an important nursery area for plaice. After spawning in the open North Sea, the juvenile fish migrate into the shallow Wadden Sea. There, they find abundant food and protection from predators. In this way, the Wadden Sea makes a vital contribution to the preservation of this ecologically important fish species.
