The Rise of Fungal Conservation in Africa

Madagascar, renowned for its unique wildlife, is home to a vast array of endemic species, including fungi, which are often overlooked in conservation discussions. Anna Ralaiveloarisoa, Madagascar's first homegrown mycologist, emphasizes the critical role fungi play in ecosystems, stating, “They feed 90% of terrestrial plants. Without them, there is no life on the Earth.” Despite their significance, less than 1% of Madagascar's estimated 100,000 fungal species have been scientifically described, highlighting a substantial gap in knowledge and conservation efforts.

Ralaiveloarisoa is part of a growing cohort of African scientists dedicated to the study and conservation of fungi. This movement gained momentum during the International Congress on Fungal Conservation held in Cotonou, Benin, where mycologists from 27 countries convened to discuss the future of fungal conservation. Nourou Yorou, general director of the Benin Agency for Science and Innovation, remarked on the evolution of fungal conservation from obscurity to a dynamic global movement over the past two decades.

Fungal conservation has historically lagged behind that of plants and animals. The International Society for Fungal Conservation (ISFC) was established in 2010, followed by the creation of the Fungi Foundation in 2012. David Minter, president of the ISFC, noted that prior to the 2000s, fungal conservation efforts were fragmented and lacked coordination. Recent legislative advances, such as Chile's 2013 law recognizing fungi in conservation, signify a shift towards integrating fungi into broader conservation frameworks.

Research increasingly underscores the ecological importance of fungi. They are essential for nutrient supply to 90% of plants and play a significant role in carbon storage, with studies indicating that mycorrhizal fungi can sequester up to 36% of annual CO2 emissions from fossil fuels. Minter likens fungi to essential but often overlooked service providers, stating, “If [waste collectors] go on strike, we sure know that they’re needed. It’s exactly the same with fungi.”

African mycologists face numerous challenges, including limited resources and infrastructure. Sydney Ndolo Ebika, the Republic of the Congo's first mycologist, established the country's first fungarium to preserve fungal specimens. In Zimbabwe, Cathy Sharp is working to enhance children's knowledge of fungi through educational initiatives, emphasizing the need for public awareness to support conservation efforts.

Following the congress, participants released the Cotonou Declaration, which aims to address the under-representation of fungi in conservation efforts globally. This document, co-authored by mycologists from four continents, outlines priorities for mycological conservation and reinforces Africa's pivotal role in this movement. Yorou described the congress as a milestone for the global mycological community, envisioning a future where fungi are recognized as a fundamental component of biodiversity conservation.

The growing recognition of fungi's ecological significance and the establishment of a collaborative network among African mycologists mark a critical turning point in fungal conservation. As these scientists advocate for the inclusion of fungi in conservation policies, the potential for a more comprehensive approach to biodiversity preservation becomes increasingly attainable.
