- •
Crown condition and leaf physiological traits were assessed in mixed forests.
- •
Tree species and Leaf Area Index were the most important predictors of defoliation.
- •
Tree diversity reduced the defoliation in chestnut and in holm oak.
- •
Defoliation has different physiological significance in forest tree species.
- •
Crown assessment is more informative when defoliation and leaf traits are combined.
