Abstract

Despite its importance1,2 , microbial life is largely absent from global conservation frameworks3,4 . Launched in July 2025, the Microbial Conservation Specialist Group (MCSG) was established as a Species Survival Commission (SSC) by the International Union for Conservation of Nature (IUCN). The IUCN is the world’s leading authority in environmental science and policy, renowned for shaping conservation priorities across governments, non-governmental organizations and international treaties. The MCSG convenes a coalition of microbiologists, ecologists, traditional knowledge experts and conservation leaders to develop and advocate for conservation tools, strategies and policies that explicitly integrate microbiology into global biodiversity governance. Despite the importance of microorganisms for ecosystem function, their role has been seen as too abstract or complex to integrate into policy. Elevating microbial perspectives within global conservation has required overcoming a deep-r
