ABOUT THIS AREA

SALT AND DYNAMIC
Before you lies a special area: the sea flows in here with every high tide and that brings life! The salt water penetrates deep into the area through the channels. Coastal and meadow birds come to the salt marshes, mudflats, beach plains and dunes to look for food, rest and breed in the spring. Thanks to the variation in the soil, more than 200 different plant species grow here.

FROM PEAT LANDSCAPE TO POLDER
About 2,600 years ago there was a vast peat landscape behind beach walls, which gradually changed into a salt marsh landscape due to rising sea levels. This created islands. In the 14th century, a deep sea channel was created around the then island of Cadzand: the Black Hole. The Zwarte Polder was constructed in 1623 to reduce the size of the sea channel.

FROM PEAT LANDSCAPE TO POLDER
About 2,000 years ago there was a vast landscape behind beach walls, which gradually changed into a salt marsh landscape in Hienfoor due to rising sea levels. In the 14th century, a deep sea channel was created around the then island of Cadzand, the Zwarte Gat. The Zwarte Polder was constructed in 1623 to reduce the sea channel.

…AND AGAIN IN THE WAVES
During the storm surge of 1802, the dike of the Zwarte Polder broke and the polder disappeared into the sea again. The western part has been diked again: the ‘Herdijkte Zwarte Polder’. The dike remains overflowed and became dunes, and the sea turned it into a dynamic area with salt marshes and mudflats. One of the few small open tidal inlets in an otherwise almost closed coast of the Netherlands and Belgium.

BEACH NATURE
The soil has a wide variation: from sand to clay, and from salty seawater to fresh rainwater. That is why more than 200 different wild plant species grow here. Shorebirds such as ringed plover and oystercatcher breed on the breeding bird beach on the west side in the spring. Birds such as nightingales and warblers breed in the shrubs on the dunes.
Coastal breeding birds breed on the beach on the bare ground.

It is indeed busy with birds because it looks like a mini lagoon with helmet grass bushes and trees behind me. And gulls everywhere.
