The WOLF Forest Protection Movement is an environmental non-profit non-government organization (NGO) working to preserve natural forests and their wildlife in Slovakia and the whole of Central and Eastern Europe. It was established in 1993 as a Slovak movement of friends of forests. The organization was founded by members of the SZOPK (Slovak Union of Nature and Landscape Preservers) group. WOLF, lead by Juraj Lukac, has worked in the forests of the Saris region in eastern Slovakia since 1980. The experience of this group became a basis for the practical activities of the WOLF Forest Protection Movement.
