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 Naturalis collections have their strong points in The Netherlands and surrounding countries, Southeast Asia and New Guinea, West- and Central-Africa, Ethiopia and the Guyanas.

The site Trinité is composed of four 3km-transects (20m wide). 5365 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 17 samples (1.20m depth max.). Laboratory analysis are available for one soil-profile.

The site Montagne Tortue is composed of one 3km-transects (20m wide). 940 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories. No under-storey plants inventory. Soils have been described using 7 samples (1.20m depth max.). No laboratory analysis available for soils.

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.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site is located at Kourouaï-Kapiri interfluve and is composed of one 140x150m-plot. A complete inventory has been made in 2009. 819 trees with dbh>=10cm have been registrated and 807 species have been identified. 98.5% of the registrated trees have been identified to the species level. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 400 meters in each direction.

The site Crique Armontabo is composed of four 3km-transects (20m wide). 5183 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 plants inventory available. Soils have been described using 12 samples (1.20m depth max.). Laboratory analyses are available for one soil-profile.

This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 59 160 ha. 67 234 trees have been inventoried in 240 plots (118 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 2009 using original maps and field note-books (indicating slopes, rivers, etc...).

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Borne frontière n°1 is composed of 3 1ha-plots. A complete inventory has been made in 2006. 645, 630 and 661 trees with dbh > 10cm have been inventoried on each plot. 641, 625 and 655 species have been identified respectivement on each plot. 99,4%, 99,2% and 99,1% of the trees have been determined until species. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 300 meters in each direction.

The site Régina is composed of two 3km-transects (20m wide). 1958 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories available. 284 under-storey plants have been recorded on 14 25m²-plots by Institut de recherche pour le développement (IRD). Soils have been described using 13 samples (1.20m depth max.) and two soil pits (1.50m depth). Laboratory analyses are available for one profile and for the two soil pits

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...).
