Uso de plantas nativas para la rehabilitación de canteras en Sonora

The Sonora state is not exempted of global warming consequences, such as the reduction of native species populations by activities like as land use change for the exploitation of aggregates (rocks) and the scarce or no rainfalls events occurred. In this work 4 species of native trees were used (mesquite, Prosopis velutina, chinese green stick, Parkinsonia microphylla, blue green stick, Parkinsonia florida and ironwood, Olneya tesota), for the rehabilitation of quarries. The germination percentage of the seeds was 95 to 99% in general. Ten specimens of each species were transplanted, the transplantation survival rate at 15 days was 100% and at 80-90% at one month. The data corresponds to the evaluation at 8 years after the transplant, where the height reached by the mesquite was 2.91 meters, chinese green stick 2.67 meters, blue green stick 2.56 meters and ironwood 1.13 meters. Mesquite cup cover was 12,315 cm², chinese green stick 9,913 cm², blue green stick 9,423 cm² and ironwood with 3,175 cm², mesquite stem coverage was 98.2 cm², chinese green stick 97.4 cm², blue green stick 96.4 cm² and Ironwood 43.4 cm², while the height growth index was 56.00 to 82.76% and the crown diameter was 99.60 to 99.86%, finally, stem diameter was 97.74 to 99.07%.
