Pollinators, such as bees and butterflies, visit flowers to harvest their nectar and pollen. They play a crucial role in flower reproduction, transferring pollen and fertilising flowers as they go from plant to plant.

Recent data shows pollinator numbers to be in decline, causing global concern. This is especially worrying for agriculture as at least 1/3 of the total volume of agricultural produce relies on pollination. This includes such everyday foods as fruits, nuts, beans and coffee. 

Insect pollinators also play a crucial part in wild food chains. An estimated 94% of the flowering plants in tropical regions cannot be pollinated any other way. This makes insect pollinators incredibly valuable, worth an estimated global value of 265bn Euros.

The declines are due to a wide range of threats including diseases, invasive species, habitat loss and climate change. The loss of 97% of the UK's wildflowers since the 1930s has made two bees locally extinct.  Central Europe, Northern Europe, the United States and Asia are all reporting losses. To reverse these declines managers must use holistic approaches that address all of these threats.
