The Harchies Marshes, located in Wallonia, have a rich and eventful history. In the 18th century, the Haine Valley was bordered by wet and marshy meadows, but no body of water existed. Between 1925 and 1930, mining caused subsidence, creating depressions invaded by the water table. In the 1950s, the surface area covered by water increased, promoting exceptional biodiversity. Between 1968 and 1971, the site drained, threatening its ecosystem. From 1973-1974, preservation efforts allowed the marsh to revive. In 1986, the site was recognized as a Ramsar area, highlighting its ecological importance. Today, it covers approximately 550 hectares and is classified as a Special Protection Area. It is home to a wide variety of habitats and more than 250 bird species. It remains a popular birdwatching site for birdwatchers and nature lovers.

There are two viewing huts on the route. But especially many ornithologists. This must clearly be a special place!

Located in the heart of the Haine valley, between Mons and Tournai, the marshy complex of Harchies-Hensies-Pommeroeul, better known as the Marais d'Harchies, is a major site for the fauna and flora of Wallonia. Covering an area of 550 hectares, this site of great biological interest is home to many species and constitutes an important transit site during bird migration and offers ideal conditions for the nesting and wintering of numerous species. Its registration as a “Ramsar” wetland confirms its importance on an international scale. https://oiseaumaraisdharchies.be/
