Bees, birds and butter: New study shows biodiversity critical for shea crop in Africa

(EurekAlert/Trinity College Dublin) Shea trees, an important agroforestry crop in West Africa, benefit from bees moving pollen between their flowers to produce fruit. A new study found that in sites with low tree and shrub diversity, fruit production was severely limited by a lack of pollination. In higher-diversity sites, more honey bees were observed, and other bees visited flowers in greater numbers, boosting pollination services.
