Thought this might be of interest:

Monitoring native bee populations on organic farms close to wild habitat,
organic farms distant from wild habitat, and conventional farms distant
from
wild habitat (conventional farms tend not to located with close proximity
to
wild habitat), Kremen's research group found that 80 percent of organic
farms close to wild habitat could rely entirely on native pollinators for
pollination services. By contrast, just 50 percent of organic farms located

distant from wild habitat could rely on native pollinators alone, and none
of the conventional farms had sufficient native pollinators for pollination

needs. Overall, native bees provided 28 percent of pollination on
conventional farms and 60 percent on organic farms.
