Floral diversity and characterization of plant groups in Atlantic forests of Cameroon
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 10, Issue 5
Abstract
Atlantic forests are part of the Guinean Low land and are known for their rich flora and fauna. A thorough botanical study has never been carried out at the level of the forest management units (FMU) located to these forests. This research therefore sought to characterize the vegetation using diversity indices and structure, to describe the plant diversity and to analyse the chorological types encountered in these forests. Twelve permanent one hectare plots were established in the two FMU’s. All trees with girth greater than or equal to 10cm were identified within each hectare, counted, measured, marked and tagged. A total of 6425 individuals belonging to 317 species, 212 genera and 60 families were recorded. Three plant groups were described based on their similarity to variables such as altitude, the soil content and rainfall. The Fabaceae-Caesalpinioideae are the most diverse in term of number of individuals. Garcinia lucida (Clusiaceae) found only in Group 1, is the most abundant species with an IVI=23.71. The Shannon diversity index (H’≥3.5)shows a forest with high species abundance and diversity. The chorological analysis reveals a predominance of Guineo-Congolese species with zoo chore species being the most dominant in all three plant groups.
