The ultimate aim of NutriB² is to support effectively the health of different wild bee species through protecting/providing nutritionally diverse and appropriate floral resources particularly in low diversity environments. In fact, many wild bee species frequently ignore plants generally used in flower strips, indicating that they do not meet their nutritional needs. Nutritionally appropriate and diverse floral communities will thus not only benefit bee communities, but most likely also other animals depending on plants as resources as well as higher trophic levels. Our approach will consequently enable us to restore overall biodiversity particularly in impoverished landscapes (i.e. landscapes with low resource quantity and quality for bees).
