Africadiv extract

This dataset is an extract from Africadiv. It provides the
information required to replicate some analyses of the Data Descriptor Ploton et al., 2020, Scientific Data. doi:10.1038/s41597-020-0561-0.
Africadiv is a network of 1-ha forest monitoring plots spread
across the moist forests of Cameroon and Gabon. In each plot, the
diameter at breast height (DBH) of all trees with DBH ≥ 10 cm have been
measured. All trees were identified in the field by expert botanists.
Herbarium samples are conserved at the Herbarium of the Université Libre
de Bruxelles (BRLU, Belgium) and the determination of the samples is
frequently updated by ULB's botanists. Leaves samples were frequently
collected along with herbarium samples for genetic analyses. Additional
information on tree structure were collected on a subset of trees across
the DBH gradient to study local tree allometry (total tree height,
trunk height, crown diameter). Four soil samples per plots were
collected and basic soil analyses are available. In order to facilitate
the use of field plots in remote-sensing studies, a GPS point as well as
laser measurements (distance, vertical & horizontal angles) were
recorded every 20 m on the contour of the plot. These data are routinely
collected and used by AMAP research unit (IRD) and partners (LaboSyst,
Yaoundé 1 University) in the frame of their research activities on
tropical forest stand structure, biomass, and remote-sensing inference
of tropical forest properties. New plots are frequently added to the
network. Scientific collaboration are welcomed, please get in touch with
