INPA | Tree species composition in ecotone forests of the eastern Maracá Island, Roraima, northern Brazilian Amazonia: preliminary data

Forest inventory carried out in the research grid of the Research Program on Biodiversity (PPBio) located in the eastern Maracá Island, Roraima, northern Brazilian Amazonia. The inventory was carried out by the Research Group "Ecology and Natural Resource Management of Savannas and Forests of Roraima", linked to the National Institute for Research in Amazonia (INPA) in December / 2017. The survey was based on 129 permanent plots dispersed in six trails that cross the research grid. Measurements of stem diameter (DBH = diameter at the breast height) of each observed individual (palms and trees) were taken. All floristic data were correlated with the dominant forest types of the sampled area.
