Data are especially provided by Institut de Pharmacopée et de médecine traditionnelles (IPHAMETRA). Data from the 123 plots of 2500 m2 (31 ha) installed in the area which will host the national projet of hydroelectric dam building have been used. Trees with diameter at breast height (dbh) ≥ 10 cm was measured. The dbh is measured with a diametric tape at approximately 1.3 m from ground, avoiding lianas growing on the trunk or 30 cm above buttresses and stilt roots.
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 123 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
The table below shows only published versions of the resource that are publicly accessible.

Gabonese biodiversity data are housed in several institutions and their availability is often problematic. To best support decision-makers and data users, data must be reliable and deliverable in appropriate formats. This requires a centralized, effective and easy-to-access database. In most African countries the few databases that exist are underused. For instance, specimen data are exploited by researchers only when they are planning field trips. As strategies to transmit relevant information on plant biodiversity to decision-makers are deficient, this project aims to mobilize biodiversity data and categorize them according to their utilization by local populations, their importance in conservation and their commercial use, in order to support their integration into policy and decision-making processes.
|Title||Mobilization and use of botanical data as decision-making tools in Gabon|
The personnel involved in the project:
Non-permanent plots of 50m x 50m (0.25 ha) were estabished
|Study Extent||Data were collected from project related to vegetation description and initial state of site of Kinguélé aval project|
|Quality Control||BRAHMS were used for quality control. These data were of high quality because species identification in the field and confirmation were done by the Herbier national du Gabon botanists.|
Method step description:
- The inventory was made in grids delimiting the contiguous plots of 2500 m2 (50 m x 50 m) characterized by an identifier which consists of a letter to indicate the position of the west-east line and a number which indicates the number of the south-north line. The geographical coordinates of all corners of the plots were recorded using GPS receiver. To characterize the floristic diversity of the study area, all trees with a diameter greater than or equal to 10 cm were recorded in each plot. These trees were then identified at the specific level. In case where identification of the tree could not be completed in the field, an herbarium samples were taken in order to confirm their determination at the National Herbarium of Gabon.
