  • 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 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 Yaroupi is composed of four 3km-transects (20m wide). 3965 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. No under-storey plots on this site. Soils have been described using 22 samples (1.20m depth max.). Laboratory analysis are available for one soil-profile.

  • The site Limonade is composed of three 3km-transects (20m wide). 3354 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. No under-storey plots on this site. Soils have been described using 16 samples (1.20m depth max.). No 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.

  • 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.

  • This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 18 737 ha. 17 560 trees have been inventoried in 80 plots (40 ha). Pre-census DBH is 10 cm on all plot. DBH have been measured by classes with a range of 10 cm. Plots have been located on GIS in 2006 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 Laussat covers a 4ha area. It is composed of one plot, managed by CIRAD. 2334 trees are being followed. A first inventory has been made in 2009
