The Kimbi Fungom National Park is reported to be relatively less diverse compared to other national parks of Cameroon. This might be due to the configuration of the landscape and habitat types. The main objective of this study was to determine the species composition, structure and diversity in the heterogeneous landscape of the Kimbi Fungom National Park defined by different habitat types. The park was divided into 20 blocks and 10 blocks were randomly selected for this flora survey. In each block, a 1km line transect was established with 5 quadrates of 20x20m. These transects were laid to cut across four major vegetation types (Lowland rainforest, gallery forest, woodland and grassland savanna). A total of 2831 stems >1cm circumference were identified and measured. This belongs to 222 species, in 54 families. Fabaceae, Rubiaceae and Euphorbiaceae were found to be the most dominant plant families. Tree density and basal area were lowest in the grassland while it was highest in the lowland forest. Species composition and diversity varied with vegetation type and landscape configuration. The lowland and gallery forest were characterized by high diversity and similar species composition, shown by the Shannon diversity index of 3.8 and forest 3.75 respectively. Three species from our survey were known to be endemic to Cameroon (Allophyllus bullatus, Cleistopholis staudtii and Magnistipula butayei subsp) while 6 species were known to bevulnerable; Afzelia africana, Afzelia bipindensis, Allophyllus bullatus, Entandrophragma angolense, Hallea stipulosa, Quassia sanguine.
