The following species are recorded in more than 50 percent of the surveyed sample plots:
Bonga: none. Number of sample plots in Bonga is very much higher than that of Boginda
and Mankira. That could be one of the reasons.
Boginda: Vepris dainelli, Chionanthus mildbraedii, Milletia ferruginea.
Mankira: Croton macrostachyus
Using the sum of relative frequency and relative abundance of species Distribution Index
(DI) was estimated (Schmitt C. B., 2006). Accordingly, the following results have been
found concerning common species and are shown in Table below (Table 10). Occasional
and rare species are listed in annex II, Table 16. In total 9 species in Mankira, 30 species
in Bonga and 18 species in Boginda are found to be rare species.
