concentrations of Ca in the bark that even surpass the concentrations of Ca in the foliage. The comparison of broadleaved species to the conifer reveals marked differences between the two. In general terms Pinus caribaea presents the lowest concentration sof nutrients in the biomas samongall the species while Hieronyma alchorneoides and Gmelina arborea present the highest concentration sof N,P,K and M gin the foliage.Terminalia amazonia and Vochysia ferruginea are characterized by maintaining higher concentrations of Ca in the bark. As observed in the table thet wo Vochysiatrees concentrate the highe stamounts
of Alon their foliage, are sultpreviously observedinother studies [19]. On the average V. guatemalensis and V. ferrugenia concentrates 49 and 65 times more Al than theaverage of there maining species.
