Foraging mushrooms and wild plants isn’t just about food, it’s a deeply social and ecological act. This global review shows how foragers act as stewards of biodiversity, caring for species, habitats, and community traditions. From alpine forests to coastal shores, stewardship practices like selective harvesting, seed scattering, and habitat tending help protect vulnerable ecosystems. These often-overlooked behaviors are rooted in care, local knowledge, and identity, making foraging a vital force for both cultural continuity and environmental resilience.
