The study
of structural and tree flora biodiversity of the forest of the Mbomo-Kelle UFA
was done on an area of 88.5 ha (0.014% of the total UFA area). The inventory
was carried out in plots of 200 m × 25 m (0.5 ha), arranged in a contiguous way
along the opened trails in the forest with an equidistance interval of 2 km. 11,012
trees of DBH ≥20 cm were counted, divided into 107 genera, 31 families and 133
species including 121 completely identified and 12 defined only in terms of
genus. Data analysis consisted of calculating relative and weighted
frequencies, the Shannon and Weaver diversity indexes, Pielou’s evenness index,
and the Jaccard and Sorensen similarity indices. Relative frequencies showed
that the most representative family in terms of species is the Fabaceae-Caesal piniodeae
with 18.05% of species and the most representative in terms of individuals is
the Burseraceae with 19.17% of inventoried trees. The principal components
analysis allowed to show inter- and intra-block heterogeneities.
