Every continent has reports of pollinator declines in at least one region/country. The losses of pollination services have been well documented in many specific instances; what remains lacking are global assessments of changes in the distribution and levels of pollination services. As the recognized drivers of pollinator losses (changing land-use patterns, pesticide use, diseases, invasive species, and climate change) are themselves changing in intensity, the global community is justified in taking note and determining the actions that will conserve pollinators. The insidious nature of the loss of ecosystem services- by slow erosion rather than cataclysmic events- demands careful monitoring.
