Project summary

Edit project overview to modify the project summary.


De Koffiegoot is een beek die loopt van het Haaksbergerveen naar de Berkel en zijn naam te danken heeft aan de bruine kleur van het veenwater.

Rijn en IJssel gaat de beek en omgeving herinrichten. Zodat het natuurlijke beeksysteem zoveel mogelijk kansen krijgt, er meer water wordt vastgehouden en de natuur beter tot z’n recht komt.

Het wordt een kleinschalig landschap met poelen, vochtige heide, graslanden en loofbosjes. De poelen worden verbonden door een smalle loop die geleidelijk aan breder wordt en begint te meanderen. Houtwallen en lokale veentjes zorgen voor een afwisselend landschap.
