Our paper presents a method of remedial planting works designed for the old Radiowo sanitary landfill. The landfill (embankment type) was established in 1962, without any environment protection systems installed at the site. The initial reclamation works on the landfill have been carried out since 1996, and were aimed at the limitation of the landfill impact on Kampinoski National Park and two nearby reserves. The vegetation cover decreased the effect of soil dusting and enhancing erosion control were the primary reclamation works introduced at the landfill site. The objectives of the whole process were mainly: stabilization of capping soil-compost layers, accelerate the processes of mineralization, and increase the evaporation of leachate from the landfill and the local composting plant. A planting of carefully selected vegetation species within the protection zones (with existing biological potential and biotic preconditioning) of the landfill slopes also is presented.
