Research on Forestry Recultivation of Sterile Dumps within the Jilţ Basin

Following the surface mining operations, large areas of agricultural land (arable land, meadows, etc.), forests, etc., are lost from the economic business in the county; all these lands, under adequate provisions of law must be reconstructed for agriculture and forestry. The current concept of sustainable development presumes also an environmental protection strategy, designed today and accepted by the countries all over the world to maintain ecological balance at the global, regional and local level. Research carried out on this theme aims to find the most effective forest species to make these areas as quickly as possible to enter the economic circuit. Orientation regarding the afforestation of these areas depends largely on the ecopedologic zone, the material resulting from the exploitation of lignite and, first of all, available investments. The present situation left by the surface mining operations within the Jilţ Basin shows that there are many areas of unproductive land that can not be included in the category of arable land. For this reason, research started aiming at the afforestation of these lands with different forest species. It was also considered the stabilization of sloping lands of these dumps in order to avoid the surprise of landslides in years with abundant precipitation. Large areas of dumps were planted with Robinia pseudacacia, familia Leguminosae in both the Mining Jilţ Basin and the Mining Rovinari Basin, these land areas being well covered by forestry vegetation. But forestry does not mean only Robinia pseudacacia, familia Leguminosae and, for this reason, the species proposed in this paper include a large diversity and provide outstanding economic results.
