The Zwart Water

Highlight • Lake

Het Zwart Water consists of a fen with woods on the edge, gale thickets, willow breeches and lean grassland. In the middle of the water there is a floating platform that birds like to use to rest and build their nest. Long ago, Zwart Water and its surroundings were an open dune landscape where the wind had free play. Sand was blown away to a hard layer in the subsoil, after which it collected around it to form dune ridges. The hard layer did not let water through and thus gave rise to a pool. Peat, better known as peat, developed in this area, which gave the water a dark color. Hence the name "Black Water".

Warandeplas

Highlight • Lake

The Warandeplas is an extensive body of water that lies between the forests of Rollekensbergen and the Visbeek valley, an extremely valuable and extremely varied nature reserve. It is a beautiful location for walking, cycling and enjoying nature. There is even a zone where your dog can freely enter the water. In 2016 a sheep grid was placed around the Warandeplas in function of the grazing by sheep. In this way variation is ensured in the structure of the landscape with a mosaic of forest, shrubs and open areas.

Snepkens Pond

Highlight • Lake

Snepkensvijver is one of the oldest nature reserves in Flanders.
The Snepkensvijver nature reserve borders the Kempense Heuvelrug and is therefore located in a landscape that was largely shaped by the winds during and after the last ice age. The name already indicates that it is a water feature, water that remains in the extinct dune pan and has formed a fen there. Due to the presence of water, the area has a strong attraction for birds. Originally it was a bird sanctuary, but over the years more and more attention has been paid to the special flora of the gradient between fen and ridge.

Good water quality is essential for biodiversity. Therefore, it is important that the nutrient-rich soil layer is not disturbed. The water then becomes cloudy and certain plants, such as algae, begin to proliferate. Algae consume a lot of oxygen at night, resulting in the animals in the pond having a difficult time. To protect this special biotope, passers-by must leave the water undisturbed. (Information board on site)

Many captivating stories have been written about this well (not just any well). The first probably dates back to 1571, when Lieske Coolbonders committed suicide by drowning herself in the well while the devil himself was pursuing her. Lieske was the illegitimate daughter of Katrien Coolbonders, who was raped by a Spanish nobleman. The nobleman was murdered by Katrien's husband. The body was first dumped in the Devil's Well. Later, it was buried somewhere nearby. (Efkesweg.be)

Het Zwart Water is a nature reserve southwest of the town of Lichtaart, which is part of the Antwerp municipality of Kasterlee, located near Lavendelweg 1-3. The area is managed by the Agency for Nature and Forests. The area is located on the Kempense Heuvelrug and consists of a fen that used to be in a drifting sand and heathland area, but was largely forested with conifers during the 19th century. On the edge of the fen you will find bog myrtle thickets, willow swamp forest and poor grassland. There is a floating dome in the fen that forms a safe resting place for birds. The forest is gradually being transformed into more mixed forest. In addition, there are remnants of heathland.

With its 16 hectares, De Duivelskuil is a rather small but very varied nature reserve. It treats you to a characteristic Kempen landscape. In addition to dry heathland and wet heathland, you will also find some beautiful fens and a piece of bog bog. A moist alder-birch forest and a dry oak-birch forest and also a lot of Scots pine.

In Snepkensvijver-Heiberg in Herentals, swamp, heathland and forest go hand in hand. The soil conditions provide typical vegetation such as peat moss, heath, small sundew, cranberry and peat fluff. The fragrant gale is also found en masse. In the drier areas, shrub heather is ubiquitous. Discover rare plant species here and completely relax.

Many imaginative stories have been written about this well (not just any well). The first probably dates back to 1571 when Lieske Coolbonders committed suicide by drowning herself in a well when the devil himself chased her. Lieske was the bastard daughter of Katrien Coolbonders who was raped by a Spanish nobleman. The nobleman was murdered by Katrien's husband. The body was first dumped in the Devil's Well. Later it was buried somewhere near it. In 1695, a man from Reusel was said to have been hanged on a gallows on the Hoge Mouw and later buried in the Duivelskuil.
