In a world which is more and more urbanized, urban forests can help reducing the negative effects as they perform a wide range of functions and important ecosystem services including cooling, pollution filtering or improvement of human well-being. However, these forests are also exposed to more risks and constraints than the natural ones. Insect attacks is one of the important damages caused on urban trees and this insect herbivory can be linked to the predation rate, urbanization, tree diversity.
This project focuses on trees in and around Nancy (France), to evaluate the effect of tree diversity and urbanization on insect herbivory and predation.
