Plant-fungal symbioses play critical roles in vegetation dynamics and nutrient cycling.  Here, we used forest inventory data consisting of three million trees to develop a spatially-resolved mycorrhizal tree map of the continental USA and understand the impacts of anthropogenic impacts on mycorrhizal association shifts. The data published here includes: 1) a list of mycorrhizal tree species, 2) tree mycorrhizal association (AM tree dominance) and climatic variables (MAP and MAT) at FIA plot level, 3) soil data at FIA subplot-level, and 4) changes in tree mycorrhizal association (AM tree dominance) and climate (MAP, MAT) and anthropogenic factors.
