The aim of this study was to analyze the growth rings and evaluate the effect of the urban environment on the growth of Terminalia catappa L. under intense industrial activity. The dendrochronological potential of T. catappa indicated sensitivity to precipitation and temperature in a more exposed urban and industrial steel pollution area. This study reinforces the importance of rainfall and temperature in regulating radial growth in tropical forests.
The aim of this study was to analyze the growth rings and evaluate the effect of the urban environment on the growth of Terminalia catappa L. under intense industrial activity. At least two wood samples were obtained from each tree with an increment borer. The regions of Volta Redonda (Northwest and Southeast regions) and Resende (used as control) were established for the collection. The dendrochronological potential of T. catappa indicated sensitivity to precipitation and temperature in a more exposed urban and industrial steel pollution area because there were differences in growth when compared to an area less exposed to the same pollution. Thus, it was possible to conclude that this species has the potential to be used as a bioindicator of anthropogenic activities. In addition, the delimitation of the growth rings of the studied species contributes to the realization of future dendrochronological studies, expanding the understanding of the behavior of this species present in urban environments at different regional scales. This study reinforces the importance of rainfall and temperature in regulating radial growth in tropical forests.
