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.

在巴西北部马拉卡亚岛东部，由生物多样性研究计划（PPBio）设立的研究网格内进行的森林资源清查。此次清查由隶属于亚马逊国家研究所（INPA）的“马拉卡亚草原和森林的生态与自然资源管理研究组”于2017年12月执行。调查基于六条穿越研究网格的129个永久样地展开。对每个观测个体（包括棕榈树和树木）的胸径（DBH，即胸高直径）进行了测量。所有植物群落数据均与样本区域的占主导地位的森林类型进行了相关性分析。
