Common Trees

Soft Wallaba is the most common tree species found in Iwokrama Forest. Others found in high densities are Baromalli, Black Kakaralli, Wamara, Mora, Crabwood, and Greenheart. The densities of stems can vary tremendously, as does the geographic variation of these densities across the reserve.

In 2003, inventories within the Forest were completed and have yielded detailed information regarding density and size. Please see the stand table (PDF) for those results (and scientific names) for the 15 most abundant species.

Of these 15 species, more than half are of proven commercial value; mostly for timber. One species is used for Non Timber Forest Products: Crabwood.

Notable species commonly found to occur in relatively high densities in northern Guyana but thus far appearing rare or absent from the Iwokrama Forest include Clump Wallaba (Dicymbe altsonii), Ituri Wallaba (Eperua spp.), Apoukito (Chamaecrista apoucouita) and Watapa (Eperua rubiginosa var. rubiginosa). In contrast, a number of tree species not well known from northern Guyana have been collected and inventoried in the area, mainly in the Tropical Dry/Seasonal Forest association.

These include the commercially important Brazilian Cedar (Cedrelinga catenaeformis), Brazil Nut (Bertholletia excelsa) and Wamaradan (Dicorynia guianensis).
