Mapping Underway at Rabi, Gabon

Enumeration of the 25-ha Rabi plot in the Gamba Complex of Protected Areas in Southwest Gabon started in mid June 2010 under the direction of Gorky Villa. David Kenfack, CTFS-SIGEO Africa Program Coordinator, visited the plot in July and August to continue training and supervision of the two field teams, each of which consists of six dedicated Gabonese men who work in rotation to ensure continual mapping and tagging.

More than 1.5 hectares have been tagged and mapped, with an average of 314 trees (dbh ≥ 1 cm) per 20 x 20 m quadrat and 7,800 trees per hectare. Forty-six species and 288 individuals were recorded in the first 20 x 20 m quadrat, with Dichostemma glaucesens (Euphorbiaceae) comprising 29% of the stems. The plot includes several large individuals of the remarkable canopy tree Eurypetalum tesmannii (Fabaceae), which has a shruby habit and can have up to 74 stems.
