During our second visit to the Oisterwijk forests and fens ( Oisterwijkse bossen en vennen ) - again on a grey, gloomy day - we made a walk along the so-called Kolkvenroute (about 3.5 km's). This nature reserve is one of the Netherlands’ most unique nature reserves with 80 fens in a stunning green expanse. Unlike many other fens, the formation of Kolkven is not created by the action of wind, but by melting water of a former river. Kolkven (main image) is a lot deeper than the others, which makes it suitable for fishing. The fen is rented by a local angling club. On our route we passed three smaller fens, including the Brandven (PiP’s). This fen (“Fire Fen”) got its name because in the past its water was used as firewater. Nowadays most of the nature reserve is owned and managed by Natuurmonumenten , a Dutch society for protecting nature reserves.

Oisterwijk is well known for its Bossen en Vennen , located south of the village. It is an area of 410 hectares with forests and dozens of fens. These fens were created during the last ice age by heavy southwestern winds, blowing sand away. The created bowls were later filled with rainwater. Because of loamy or primal (iron) layers, the water remained in the bowls, creating fens in a bare landscape. The forests around the pools have been planted since the nineteenth century. Most of the nature reserve is managed by Natuurmonumenten , a Dutch organisation founded in 1905 that buys, protects and manages nature reserves in the Netherlands. I took this pictures on a grey day at the Groot Aderven , one of the many fens.
