Abstract

To meet the need for wood in the African savanna zone, forest plantations have been established since the 1930s. Exotic tree species of the genera Pinus and Eucalyptus are the major groups planted in the Western Highlands of Cameroon where they form artificial forests whose mycoflora is not yet documented. This study aimed at comparing the macro-fungi diversity in mature eucalyptus and pine plantations in tropical savannas, particularly in the Melap Forest Reserve. Four permanent plots of 1000 m2 were installed in each plant community, sporophores were collected and identified from April to June 2016; species richness and generic diversity were calculated. A total of 125 species were inventoried. Taxonomic diversity was significantly higher in Eucalyptus communities than in Pinus communities, with 107 and 33 species respectively. The number of ectomycorrhizal species was higher in the eucalyptus plots where a few locally consumed species were found. The mycofloral abundance in Eucalyptus communities is explained by the presence of local tree species hosting ectomycorrhizal fungi, such as Uapaca guineensis.
