This database records the collection of leaf or cambium samples of African plants (mostly Guineo-Congolian forest trees) conserved at the Evolutionary Biology and Ecology Unit of the Université Libre de Bruxelles (team lead by Olivier Hardy) for DNA analyses. The material is used for genetic analyses in the fields of phylogenetics, population genetics and phylogeography. Each sample has a unique identifier in the form of 2-3 letters (most often the initials of a collector) followed by a 4 digit number. A sampe corresponds to one individual plant collected in the field, or sometimes taken from an herbarium voucher conserved in a herbarium collection, which has been identified to species or genus level and geolocated.

This dataset gathers the floristic composition in a network of about 100 transects across terra firme forests in Gabon, considering stems above or equal to 5 cm diameter at breast height. In each transect, the following data are collected : 1. Diameter at breast height (dbh), 2. Species identification. Herbarium samples are conserved at the Herbarium of the Université Libre de Bruxelles (BRLU, Belgium) and the database is frequently updated by ULB's botanists. 3. GPS geolocation. These data are collected and used by Evolutionnary Biology and Ecology unit from the Université Libre de Bruxelles (ULB) and Missouri Botanical Garden (MBG), Central Africa Program.
