13. Annual tree rings in Piptadenia gonoacantha (Mart.) J.F.Macbr. in a restoration experiment in the Atlantic Forest: potential for dendroecological research
ABSTRACT The tree Piptadenia gonoachantha is widely used in forestry and in forest restoration projects, which require methods for evaluating tree growth. Long-term studies are necessary to determine patterns and detect changes in species growth rhythms. Tree ring analysis provides a precise method for determining age and documenting long-term growth trends
