title: Data from: Herbivory on the pedunculate oak along an urbanization gradient in Europe: effects of impervious surface, local tree cover and insect feeding guild

description: Urbanization is recognized as an important driver of the diversity and
 abundance of tree associated insect herbivores, but its consequences for
 insect herbivory are controversial. A likely source of variability among
 studies is the insufficient consideration of intra-urban variability in
 forest cover. With the help of citizen scientists, we investigated the
 independent and interactive effect of urbanization and local canopy cover
 on insect herbivory in the pedunculate oak (Quercus robur) throughout most
 of its geographic range in Europe. We found that the damage
 caused by chewing insect herbivores as well as the incidence of
 leaf-mining and gall-inducing herbivores consistently decreased with
 increasing urbanization around focal oaks. Herbivory by chewing herbivores
 increased with increasing forest cover, regardless of urbanization. In
 contrast, an increase in local canopy cover buffered the negative effect
 of urbanization on leaf-miners and strengthened its effect on
 gall-inducers. These results show the complexity of
 plant-herbivore interactions in urbanized areas, highlighting that the
 presence of local canopy cover within cities has the potential to
 attenuate or modify the effect of urbanization on biotic interactions.
