The ethnobotany survey identified 64 species of trees useful for the populations among the diversity of the plants of the quarry. The most cited for medicinal uses are: M. lucida, A. indica, S. siamea. The most cited for nutrition are: M. indica, A. muricata, A. digitata, P. guajava, M. olifera, V. doniana. The most cited for ceremonial uses are: G. ternifolia, M. excela, D. arborea. These trees with higher frequency of use must be included in the reforestation program, in order to preserve somewhat the ecosystem functions of these plant formations.
Germination tests will be undertaken on some of these plants.
In addition, it is also important to ensure that the natural plant recolonization of the quarry incorporates these useful woody species.
