Our paper focuses on complex research into the issue of waste disposal and the possibilities of using bioindicators to assess landfill impact on the surroundings. In 2010 we conducted a floristic survey and set up a list of the occurring species of vascular plants. The subject of research was surface area of the landfill and its immediate surroundings. During floristic research in 2010 we recorded 88 species that were compared with the list of 94 plants detected in 2007. Based on vegetation biomonitoring, we did not find any adverse influence of the landfill on the biotic composition of the environment. Neither had we recorded any alarming signs such as, e.g., leaf area chlorosis or necrosis, which would indicate direct impact on the local environs due to the operation of the sanitary landfill.
