Simply put: wherever the tree frog croaks and thrives, nature is intact. Werner & Mertz has had the frog in its logo for more than 100 years. Our mascot inspires us to act as an advocate for sound ecological management. Since 1999 we have worked with NABU in Rhineland-Palatinate on the cooperative effort known as "Frosch protects frogs".
A project that began right at our doorstep in the Rhine floodplain has since moved into international circles. With the WWF (World Wildlife Fund) we are working to protect riverine environments in several European countries.
