For most Americans, pollen means allergies and bees mean stings--
but to farmers, when one out of every three bites of food people take is made
possible by a pollinator, bees and pollen mean much more. Pollinators play a
tremendous economic role. The problem is, too many people see the pollination process
as a free service from nature; most people don’t know the unprecedented threats
facing wild and managed pollinators worldwide.
Managed honey bee colonies have shrunk by 25 percent
since 1990, and there are fewer bee hives now in the United States than at any
time in the past 50 years. For more than a decade, biologists have documented declines
in populations of migratory pollinators including butterflies, bats and birds.
Habitat loss and excessive exposure to agrichemicals, as well as spread of diseases,
parasitic mites, invasion of Africanized honey bees, and elimination of
government subsidies for beekeepers are most often mentioned for what’s been
called an impending pollination crisis.
Pollinators are particularly important to fruit,
vegetable and nut growers, with crops valued in the billions. California
producers rent half a million bee hives a year for almond trees alone.
On your land, there are several things you can do to help
pollinators. Don’t disturb wild areas. Bumblebees nest in grass in old mouse
nests, for instance, and other bees nest in dead wood. Plant pollinator
friendly crops. Clovers, alfalfa, trefoils and other legumes enrich and protect
the soil and are pollinator favorites. Use conservation buffers.
Let plants bloom. Try to time mowing, tilling or grazing
management decisions so that plants have the opportunity to bloom. Time
pesticide application. Your pesticide label lists bee toxicity and residual
time. Pollinator-friendly plants include many native wildflowers. An excellent place
for them is in streamside buffers next to crop fields.

Did you
know....
A bee's wings vibrate about
435 times a second. More than
75 percent of the crop plants
that feed the world, and many
plant-derived medicines in our
pharmacies rely on pollination
by insects or other animals for
healthy fruit development.
