AB Mushrooms play a provisioning ecosystem service as wild food. The abundance of this resource shows highannual and interannual variability, particularly in Mediterranean ecosystems. Climate conditions have beenconsidered the main factor promoting mushroom production variability, but several evidences suggest that forestcomposition, age and growth play also a role.Long-term mushroom production datasets are critical to understand the factors behind mushroom productivity.We used 22 and 24 year-long time series of mushroom production in Pinus pinaster and Pinus sylvestrisforests in Central Spain to evaluate the effect of climate and forest productivity on mushroom yield. We combinedclimatic data (precipitation and temperature) and remote sensing data (soil moisture and the NormalizedDifference Vegetation Index, NDVI, a surrogate of primary productivity) to model mushroom yields for eachforest and for the main edible species of economic interest (Boletus edulis and Lactarius deliciosus).We hypothesized that mushroom yield would be related to (i) forest primary productivity inferred from NDVIaffects mushroom yields, that (ii) soil moisture inferred from remote sensors will equal the predictive powerprecipitation data, and that (iii) combining climatic and remote sensing will improve mushroom yield models.We found that (i) previous year NDVI correlated (r =0.41–0.6) with mushroom yields; (ii) soil moisture fromremote sensors rivaled the predictive power of precipitation (r = 0.63–0.72); and (iii) primary production andclimate variances were independent, thus the combination of climatic and remote sensing data improved modelswith mean R2adj as high as 0.629.On the light of these results, we propose as a working hypothesis that mushroom production might bemodelled as a two step process. Previous year primary productivity would favour resource accumulation at treelevel, potentially increasing resources for mycelia growth, climatic conditions during the fruiting season controlthe ability of mycelia to transform available resources into fruiting bodies
