This dataset is contains herbarium specimens collected in the Dzanga-Sangha Reserve in the Central African Republic. These data are collected and used by David Harris at the Royal Botanic Garden Edinburgh, scientific collaboration are welcomed, please get in touch with a point of contact.

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.

This database contains botanical records either relating to material present in one of the Naturalis collections, or to material that has been or is being used in research projects. The records usually relate to herbarium specimens, but it also contains data on silica-gel samples, wood samples, spirit collections, carpological collections, etc. rarely to observations only.

The site Crique Bastien is composed of two 3km-transects (20m wide). 2608 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories available. No under-storey plants inventories are available. Soils have been described using 3 samples (1.20m depth max.). No laboratory analysis available for soils.

This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 40 556 ha. 25 735 trees have been inventoried in 169 plots (82 ha) Pre-census DBH is 15 cm on all plot (originally trees with DBH 10-15cm have been measured on one plot out of 10 but not included in the digital version) DBH have been measured by classes : 15-20 cm for the first class and with a range of 10 cm since 20 cm. Plots have been located on GIS in 2009 using original maps and field note-books (indicating slopes, rivers, etc...).
