C. Boginda
Olyra latifolia, Poecilostachys oplismenoides and Oplismenus undulatifoliu are the only three

Summary
The highest grass species per hectare is recorded in Bonga (nearly 500,000). Within this forest
area, Tectaria cf. gemmifera is the most abundant species, 281,000. The least recorded species
is Oplismenus hirtellus, 3000 (figure 12). On the Mankira forest less amounts of grass is
recorded, nearly 170,000. In this forest Oplismenus undulatifolius is the highest number

3.3.7.2 More than 90 trees per ha are estimated, the highest recorded being
Eucalyptes species (12.5%). Most of this species are planted around homesteads and
sometimes along the roads. Next to Eucalyptes, Milletia ferruginea, Cordia africana,
Croton macrostachyus and Albizia gummifera are kept in farmland for the different
uses they give to the households. These species comprise 11.5, 9.4, 9.4 and 6.3

abyssinica, Syzygium guineense, Clausena anisata, Enset ventricosa, Vernonia
