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.

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 ONF in 1976. The block covers 22 087 ha. 54 020 trees have been inventoried in 235 plots (164 ha) Pre-census DBH is 10 cm on one plot out of two and 40 cm on the others. DBH have been measured by classes with a range of 10 cm. Plots have been located on GIS in 2010 using original maps and field note-books (indicating slopes, rivers, etc...).

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Risquetout covers a 23,7ha area. It is composed of 4 plots managed by ONF. 7174 trees are being followed since 1995. 9 campaignes of inventories have been made in 1995, 1999, 2001, 2002, 2003, 2004, 2006, 2008, 2009.

The Nouragues forestry experimental site is located the Nouragues experimental station in French Guiana (other experimental sites than Nouragues plots are established in Nouragues station). This experimental site is composed by several plots not contiguous, some of them are divided into smaller plots (1ha). For each plot, the following information is recorded for all trees and lianas with DBH ≥ 10cm : 1. location of individuals inside the plot, 2. botanical identification (when it is possible), 3. diameter at breast height, or 30 cm above last aerial root, last buttress or last irregularity, 4. total height of tree (subsample). Since 2012, on Grand Plateau and Petit Plateau : 1. coefficient of light exposure 2. coefficient of infestation by lianas in tree crown.

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Régina St Georges covers a 14ha area. It is composed of one plot managed by ONF. 8587 trees are being followed since 2003. 5 campaignes of inventories have been made in 2003, 2005, 2007, 2008, 2009.

The site Haute Beiman is composed of four 3km-transects (20m wide). 5207 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. 833 under-storey plants have been recorded on 44 25m²-plots. Soils have been described using 18 samples (1.20m depth max.). One laboratory analysis available for soils.

The site Camp Caïman is composed of four 3km-transects (20m wide). 4018 trees with dbh>=20cm have been recorded by Office National des Forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. There is no inventory of under-storey plants on this site. Soils have been described using 10 samples (1.20m depth max.). No laboratory analysis available for soils.

This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 63 128 ha. 58 451 trees have been inventoried in 250 plots (123 ha) Pre-census DBH is 10 cm on all plot DBH have been measured by classes with a range of 10 cm since 20 cm. Plots have been located on GIS in 2006 using original maps and field note-books (indicating slopes, rivers, etc...).
