Statement

The forest inventory was conducted annually from 2017 to 2019. The first inventory (2017) took a longer time to be carried out (June- November), because it involved the botanical identification of the species. The second and third inventories were made only in May. The diameter was collected at 1.3 m above the ground with a diametric tape in trees with DBH > 10 cm. In some cases, the diameter was collected above that height because of the presence of buttresses or some deformity at that point. For quality control, the staff was trained before collection and the data were entered into the computer in the field, to avoid errors. The recruitment was the inclusion of new individuals who reached 10 cm of DBH, and tree mortality was also recorded. More precise growth measures and with a higher frequency of collection, are obtained by dendrometric bands, which were installed in 1299 trees. The measure contains the distance in circumference (mm) from a window on the dendrometer band measured with a digital caliper, where that distance changes when the trunk grows. We avoid collecting data during rain, because the instrument is sensitive to humidity. In 2018, the data were collected in April, June, July, August, September, October and November. In 2019, the data were collected in January, February, April, July and October and in 2020 the data were collected in January.
