ABSTRACT
BACKGROUND: In seasons of food shortage, local communities across Africa use wild edible plants and mushrooms (WEPM) that contribute significantly to food security by supplementing households' diets and providing alternative income. In the Bamenda Highlands of Cameroon, their biodiversity is believed to be rapidly declining as a result of land use change. Despite their potential beneficial values, there has been only limited research on this topic in this area. This study aims to document traditional knowledge related to the use of plants and mushrooms for food purpose by indigenous people of the Bamenda highland. METHOD: Ethnobotanical surveys were conducted in 6 localities (Mbengwi, Bafut, Nkwen, Mankon, Bambili, and Widikum) of the Bamenda Highlands of Cameroon, and 121 individuals were interviewed on commonly gathered and eaten WEPMs and their perception on their availability. Respondents were permanent residents selected based on their willingness to participate in the study. Specimens of recorded plants were collected and processed for future identification at the National Herbarium of Cameroon. Their nutritional potentials are discussed based on available literature. RESULTS: A total of 47 species were recorded including leafy vegetable, spices, fruits, roots/tubers, and mushrooms. The top 5 most frequent are Amaranthus sp. (6.6%), Termitomyces clypeatus (6.4%), Irvingia gabonensis (5.2%), Ricinodendron heudelotii (5.1%), and Aframomum sp. (4.5%). Leafy vegetable and spices are the most diversified group with 13 species each. All recorded species are important from nutritional and pharmaceutical points. However, many of their values remain uninvestigated, while their natural populations are facing threats of degradation. CONCLUSION: WEPMs have great potential to contribute to food and nutritional security in the study area. Sound nutrients and metabolites profiling of poorly known species can enhance their contribution in addressing food insecurity.
