Factors of Reclamation Success at the Lignite Strip-Mined Land in Northern Greece
The adverse ecological conditions at the lignite mines of Ptolemaida make the landscape reclamation difficult. The naturally established vegetation and soil properties were studied prior to reclamation. Various forest species were planted to assess the afforestation potential. The natural vegetation was heterogeneous but can be used for the analysis of the site. The soil of the spoil heaps was heterogeneous with unfavourable physicochemical properties. Surface soil temperature was still 24ºC higher in bare soil than in soil covered with vegetation. The most successful species of the afforestation trial were Robinia pseudoacacia and Cedrus atlantica. Covering of fly ash spoils with topsoil presented poor results, while sewage sludge gave a favorable amelioration response in areas with high fly ash content. Topsoil from older stands was the suggested method to establish Robinia pseudoacacia. Reclamation success was dependent on appropriate planning; thus, the new landscape had to be designed in harmony with the surrounding landscape before the start of the mining activity.
