Autoecological study of Ricinodendron heudelotii (Baill) Pierre et Pax. in Agulli forest

G Anjah, M Oyun

Abstract


Autoecology seeks to explain how, or to what extent species are regulated in nature, why some are common, others, rare, and why some remain relatively rare over many consecutive generations. Timber and non-timber resources have suffered serious decline due to unregulated exploitation. More than 11million hectares of mature tropical forest are converted into agricultural, pasturelands, and other land uses every year threatening the existence of species of ethnoforestry importance such as Ricinodendron heudelotii. Two sites of land were demarcated in Agulli Forest Reserve, Menchum Division of Cameroon. Each site had 20 subplots of 20 m x 25 m, mapped out systematically. This study aimed to investigate the stem density (D), frequency (F), cover (C), and the regeneration potential (RP) of Ricinodendron heudelotii. The t-test was carried out to determine the differences for independent variables of each site. D, F, C and RP for Ricinodendron tree stands at both sites were not significantly (p>0.05) different.
