Local resources, linear elements and mass-flowering crops determine bumblebee occurrences in moderately intensified farmlands

| Type artikkel: Publisert studie
There is consensus that land-use change is a main driver behind the recent declines of many pollinator populations in Europe. However, it is still not adequately understood how the local resource quality and landscape composition influence pollinators, and if and how the effects vary in space and time.

We analysed the influence of landscape-(2 km radius) and local scale- (50 m transects) resources on
bumblebee species richness and abundance during two years in South-eastern Norway, where agriculture is highly modernised but landscapes still show limited spatial homogenization. Local flower density and species richness were strongly positively associated with bumblebee densities and species richness, but higher landscape-level flower species richness were linked to lower local bumblebee abundances.
