Plant Assemblages along an Altitudinal Gradient of Mount Oku Forests (Cameroon) | Chapter 09 | Advances and Trends in Agricultural Sciences Vol. 3
Plant assemblage organization along
physical environmental gradients remains a central issue of community on local,
regional or continental scales. Mount Oku, commonly known as KilumIjim,
situated at the North-west Cameroon has the most important remnant of
Afromontane forest in Central Africa. These forests are recognized as a
globally important center of endemism and a hotspot for biodiversity
conservation but they are now undergoing unprecedented degradation. The aim of
this study is to identify different plant assemblages in Mount Oku forests. In
order to explore variations in vegetation composition of the study area, we
realized 102 floristic plots along an altitudinal gradient. The floristic plots
were subjected to a hierarchical cluster analysis (HC) using the Ward method.
Our results allowed us to reveal 9 plant assemblages on Mount Oku, situated at
different altitudinal levels. At the landscape level, this forest cover is old,
but the plant communities composing it are largely recent because they emerge
from secondary dynamics following various disturbances of the inner forest
(Crops, pastures, logging, etc.). These plant communities cover a large
altitudinal range. However there are still communities of ancient forests but
very disturbed, situated on altitudinal levels from about 1900 to 2600 m. The
general composition of the forest flora of Mount Oku indicates that this
vegetation has preserved characteristics of a tropical Afromontane flora. The
results show that the composition of plant communities is determined mainly by
human activities that tend to erase the influence of natural factors such as
altitude.
