Abstract:
The recovery of degraded areas caused by mining activities can be considered a complex step due to the variety of challenging degradation scenarios observed. The costs of conventional methods of recovery, based on planting seedlings, are usually high because they are dependent, for example, on the establishment of a seedling nursery, which involves costs related to: its installation and maintenance; the production of seedlings; and planting. These processes include costs of: construction of the nursery; acquisition of inputs; labor for planting and maintenance; and transportation costs. Having in mind that these high costs of recovery can be avoided by the use of sustainable solutions and, given the large number of species that can be used to recover degraded areas, this article presents the process of selecting plant species with potential for seed pelletizing, to be used in direct germination in the degraded area. Manual and/or mechanized sowing was considered to apply the pellets on cut slopes and/or areas destined for forest recovery, in order to rationalize the recovery process and favor its effectiveness, with a positive impact
on costs. The selection process identified six plant species considered potential for pelletizing: two arboreal species – Cassia ferruginea and Schinus terebinthifolia; two sub-shrubs – Lepidaploa aurea and Stylosanthes sp.; one herbaceous plant – Echinolaena inflexa; and one shrub – Crotalaria spectabilis. The selection of these species allowed combining diferent species in the pelletizing process, ensuring structural and functional diversity in the case of multiple seeds per pellet.
