Ecological restoration of species-rich grasslands remains a priority for the conservation of biodiversity. Torrez et al. (Applied Vegetation Science, this issue) determined if plant species recolonization of degraded nutrient-poor grasslands could be increased by adding a local source of arbuscular mycorrhizal fungal (AMF) inoculum at different distances from intact remnant grasslands. They highlight the important role of below-ground processes on restoration success.
