This nature reserve is located in the stream valley of the Astense Aa brook
This nature reserve is located in the stream valley of the Astense Aa brook. Here, a brook still freely meanders through flower-dotted meadows and old forests for two kilometres. The heavy oak trees have sometimes started to lean over due to the weak soil and the abrading waters of the Aa. The winding brook deposits a layer of sediment on one side of the bank while the other - steep - bank is abraded. Consequently, many different habitats, including islets, have formed, for various types of plants and animals.
In De Berken nature reserve the river Aa meanderingly finds its way. You can visit this special piece of nature by embarking on the ‘Woudloperspad’ trail (starting point at Hazeldonkseweg between Liessel and Vlierden).
