The biological farm Biohof Bakenhus wished a redesign of their nature trail information boards. The signposts now have a fresh, modern design and offer the visitors up to date and interesting facts combined with interactive information offers. As regards content there are important topics of agriculture, i.e. the relation of farming and water protection, closed loop recycling management and forms of cultivation as well as livestock breeding. Two bigger interactive exhibits expand the offer in a sculptural way, the visitors i.e. can puzzle the general principle of the regional water supplier (OOWV) that runs the farm. Bright yellow cow-signposts offer the visitors orientation on their tour round the farm.
