The aim of the work was to quantify the biomass, and potential for renewable energy production, of a stand of Scots Pine (Pinus sylvestris L.), in the first age group (up to 20 years), that grow on the external slope of the »Bełchatów« lignite mine. The results were compared to managed forests in the vicinity of the slope. The research was conducted on 8 experimental plots (10 x 10 meters) in two trophy variants (quaternary loamy sands and tertiary pyrytic strata after neutralization) using 12-19 year old tree stands, with 4 replications for each variant. One control plot was arranged in managed tree stands adjacent to the mine. It was found that post-mining sites, compared natural site, have an average 30% potential for biomass production and carbon sequestration. The range of tree stands' biomass, on the lignite mine slope, was 8 to 40 Mg ha/-1, and average 25 Mg ha/-1 dry biomass. Potential production of renewable energy was estimated to be 80 to 400 kJha/-1 x 10/6, and average 240 kJ x 10/6ha/-1. Total energy potential on the external slope plateau (approximately 300 ha) was 24 000 to 12 000 and average 130 000 kJ x 10/6 ha/-1. The results show the potential to manage post-mining sites, as tree plantations for renewable energy production.
