AB Forest plowing to create level terraces was part of Spain’s 1950s reforestation strategy, preparing sites forplanting. Although this practice has been controversial due to its short-term negative impacts on soil properties,its long-term effects on ecosystems affected by megafires may have important implications for fungal communityrecovery. This study evaluates the impact of historical terraces on soil fungal communities under post-megafireconditions. The research was conducted in the Sierra de la Culebra (Zamora, Spain), the site of the largestrecorded wildfire in the country’s history. The objectives were: (a) to compare soil chemical properties andvegetation cover between terraced and non-terraced plots; (b) to assess the diversity and composition of fungalcommunities; (c) to analyze the composition of fungal trophic guilds; and (d) to examine fungal interactionsunder post-fire conditions. Terraces significantly modified pH, the C/N ratio, and grass cover, generating mi-crohabitats that act as nutrient islands for fungi. Fungal richness and diversity remained stable, but communitycomposition shifted. Fifty out of 145 fungal indicator genera were exclusive to terraced plots, including thearbuscular mycorrhizal genera Acaulospora and Ambispora, and the saprotrophic genera Pyronema and Holter-manniella. Saprotrophic fungi, the dominant trophic guild, were more abundant in terraced soils. Soil pH, ni-trogen, potassium, C/N ratio, and grass cover were significantly correlated with fungal dynamics.
