Competition for resources between arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) plants can alter belowground mycorrhizal communities, but few studies have investigated host effects on both AM and ECM communities. In Central Mexico, the AM plant  Juniperus deppeana  is frequently used for reforesting areas affected by soil erosion, while the surrounding native forests are dominated by ECM oak trees. Oaks are capable of associating with both AM and ECM fungi during part of their life cycle (a feature known as dual mycorrhization) but it is unclear whether junipers possess such ability. To assess how juniper planting may affect belowground fungal interactions with oaks, we investigated mycorrhizal associations in  J. deppeana  and  Quercus rugosa  seedlings along a disturbance gradient: a native oak forest, a mixed  Juniperus-Quercus  population in secondary vegetation and a juniper site severely degraded by mining extraction. We measured root colonization and identified fungal communities using soil and root meta-barcoding of the ITS2 rDNA region. ECM fungal community composition was strongly affected by disturbance (regardless of host), while the community composition of AM fungi was mostly host-dependent, with a higher AM fungal richness in  J. deppeana . Importantly, the fungal communities associated with  Q. rugosa  seedlings significantly changed in the vicinity of juniper trees, while those of  J. deppeana  seedlings were not affected by the presence of oak trees. Even though ECM fungal richness was higher in  Q. rugosa  and in the native forest, we detected a variety of ECM fungi associated exclusively with  J. deppeana  seedlings, suggesting that this plant species may be colonized by ECM fungi. Our results indicate that  J. deppeana  can alter ECM native fungal communities, with implications for its use in reforestation of mixed oak forests.
