The entire area, 86 hectares in size, is owned and managed by the city of Kortrijk. It is located at the highest point of Kortrijk. The Marionetten urban green space itself is 57 hectares. The nature reserve was developed from 1996 onwards on the former grounds of nv Dakpannenfabriek Pottelberg, which received a permit in the 1950s to extract brown and blue clay here. After the clay extraction ceased, the pit was filled with waste. In 1996, the pit was covered, after which it was laid out as a nature reserve. The unfilled clay pit forms the pond. From 2008 onwards, this part forms the central part of the Marionetten urban green space: between Canaertstraat and Bosstraat. A RUP (Urban Development Plan) was drawn up for the entire zone (86 ha) and an implementation plan was drawn up, which was carried out step by step and completed in 2004. As of today, the Marionetten urban green space has not yet been fully acquired; parts still need to be purchased or are subject to an agricultural lease. The previous history of the site now creates differences in elevation. At the highest point stands the large Libel, containing information about the area, fauna, and flora. A staircase has been built on the side of the pond. Source: natuurpunt.be

The Bergelen Provincial Estate in Wevelgem developed around a 10-hectare artificial sand extraction pit. The sand was used for the construction of the E403 (A17) motorway in the early 1970s. The municipality purchased this pit and surrounding land between 1989 and 1995. Various planting activities and numerous management works (reprofiling the banks, creating a water berm, building observation huts and walls, creating walking paths, constructing a bat shelter, digging ponds, etc.) were carried out by the municipal council. This created a small but very interesting nature reserve. In 1996, the farm and the 29 hectares of surrounding agricultural land were purchased by the province, and large parts of the newly acquired area were afforested. In 1999, the province entered into a lease with the municipality for the management of the Bergelen pit and its surroundings. This created the Bergelen Provincial Estate, which currently covers an area of 47 hectares. The Heulebeek stream flows along and through the estate, still following a largely natural course there. You'll also find the Bulskamphoeve, first mentioned in Gullegem in 1549. It's a historic farmstead whose horseshoe-shaped buildings are situated within the ramparts. The farmstead was destroyed several times during wartime and subsequently rebuilt or renovated. The current building is believed to date from 1775. A protected monument, the Meiboom, also stands in the area. This is a group of six lime trees with a large iron cross in the center. Source: wevelgem.be

The filter ponds in Leers were built to supply water to the Roubaix Canal, which is located nearby. Their primary function is to purify some of the water from the Grimonpont wastewater treatment plant. This plant initially filters 75% of the water; the ponds then process the remaining 25%. This final filtration takes seven days. During this process, the water flows through several ponds, moving from one to the other by gravity. This filtration technique is called phytoremediation: the water is naturally purified by algae, plants, and microorganisms that thrive in these ponds. In Leers, plants such as yellow iris and purple loosestrife, among others, play this purifying role. After seven days of filtration, the water flows into a final 9,000 m² basin. At this stage, it is perfectly purified and of very high quality. This final basin, known as the "storage basin," is the final step before the water is conveyed to the canal. The Leers filter ponds, formerly a landfill, are now a peaceful 5-hectare nature reserve, perfect for a relaxing walk, alone or with the family. The area is home to around thirty bird species, including the coot, the Mediterranean gull, and the reed bunting. If you look closely, you might even be lucky enough to spot a smooth newt swimming in the ponds, searching for small invertebrates to feed on. To protect the environment and wildlife, dogs must be kept on a leash on the paths and are not permitted in the winding sections of the ponds. Source: enm.lillemetropole.fr

With the realisation of Bissegem Plage, Bissegem will gain an attractive and peaceful location. It will be a beautiful piece of nature of almost 10,000m² (1ha) that will be permanently free from construction. In this way, we will preserve the unique green character along the Leie. This will undoubtedly become one of the most beautiful parts of Bissegem. In this zone, we will set up a water buffer basin. We will collect all the rainwater from the Driekerkenstraat here. It concerns two buffer basins, one of which overflows into the other. They are a maximum of half a metre deep. The largest of the two will never be dry. A jetty (wooden terrace) will partly bridge this basin. Here, everyone can enjoy the peaceful atmosphere and the passage of large boats. We provide a connection with the cemetery. In a large part of the site, children can romp and play freely. This is also possible in the smallest buffer basin. (info City of Kortrijk)
