Description of the subject. Edible mushrooms are highly valuable non-wood forest products exploited for food and trade by local populations in the miombo area. Fungal diversity and natural production of edible mushrooms in African miombo woodlands are assessed and quantified for the first time. Objectives. The study aims to characterize the mycodiversity and compare the natural production in different miombo types to help manage this vulnerable ecosystem service. Method. A standardized data collection method was used in three study sites with different miombo types of Burundi and DR Congo. Sixty field surveys were conducted weekly in 22 permanent plots during fruiting periods. Results. The study revealed a high variation in mycodiversity according to the miombo type. Based on fresh biomass production and compared to saprotrophic taxa, it is shown that ectomycorrhizal fungi represent the most productive edible fungal component in African miombo woodlands. Conclusions. Since ectomycorrhizal host trees are systematically felled for fuelwood and charcoal production, their obligate symbiotic fungal partners are particularly vulnerable. It is suggested that for sustaining ecosystem services delivered by wild edible ectomycorrhizal fungi, forests dominated by host trees from the genera Julbernardia, Brachystegia, Isoberlinia, Uapaca and Marquesia, should be separed from clear-felling or frequent and excessive coppicing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
