RAVON is a professional organization concerned with the conservation of reptiles, amphibians and freshwater fish. We are one of several non-governmental organizations (NGO) engaged in the conservation of the Dutch flora and fauna. RAVON operates independently, but also collaborates on projects. The aim of RAVON is to increase the number of sustainable populations of amphibians, reptiles and freshwater fish in the Netherlands. As an independent NGO, we also influence regional and national policy to achieve this goal. Our work is based on research and uses best conservation practices.
