The Herperduin nature reserve is approximately 400 hectares and is owned by the municipality of Oss. It used to be a heathland, drifting sand and agricultural area, but from the end of the 19th century it was planted with Scots pine to capture the drifting sand and supply mining wood.
There are still drifting sand remains in the area and there are also some lakes, namely the Klompven and the Groot Ganzenven. The latter is a natural fen. It has been drained in the past to serve as a pasture area. Now it has been excavated again and returned to its natural state. Small sundew is growing again.
The badger is traditionally quite numerous in this area and the surrounding area. A number of walking routes have been set out within the area. Since 1998, Scottish Highlanders and Exmoor ponies have been used to graze the area. The Scottish Highlanders were replaced by Taurossen in mid-2014.
The Maashorst
With a size of 3,500 hectares, De Maashorst is the largest contiguous nature reserve in North Brabant. It contains hundreds of plant species, almost 150 bird species and more than 25 mammals.
De Maashorst used to be rich in fens and swamps and this is reflected in the many species of amphibians and reptiles that you still find here. Hundreds of insect species have also chosen De Maashorst as a habitat.
The four orphan reserves, the so-called Wet Natural Pearls, that De Maashorst has in abundance are special. In those areas, thanks to earth fractures, groundwater comes to the surface - not at a low level, but at a higher level. The calcareous groundwater flowing from high to low provides the areas with special vegetation.
