This data set consists of data collected from one field season (2018) from the ORPHEE tree diversity experiment run by INRA Bordeaux in SW France. Data was collected on tree traits (tree height, shoot length), abundance of leaf miners, damage by leaf chewers, and leaf damage by oak powdery mildew, a foliar fungal pathogen. Data was collected from plots differing in tree species richness and drought treatment.
