What is pollination and who does it?
Pollination is a vital stage in the life cycle of all flowering plants.  When pollen is moved within a
flower or carried from one flower to another of the same species it leads to fertilization.  This
transfer of pollen is necessary for healthy and productive native and agricultural ecosystems.  
Pollination, in some cases, by multiple pollinator visits to a single flower, ensures that a plant will
produce full-bodied fruit and a full set of fertile seeds.  With no pollination at all, most plants could
not produce fruit nor set seed and many of the foods we eat would no longer be available.
* About 75% of all flowering plant species need the help of pollinators to move their pollen grains
from plant to plant for fertilization
* About 1,000 of all pollinators are vertebrates such as birds, bats, and small mammals
* Most pollinators (about 200,000 species) are beneficial insects such as flies, beetles, wasps, ants,
butterflies, moths, and bees
* Bees, both managed honey bees and native bees, are the primary pollinators

Why are pollinators important to us?
The work of pollinators ensures full harvests of many agricultural crops and contributes to healthy
plants everywhere.  Pollinators are often critical to a healthy ecosystem.  Their role has [until now]
been largely unnoticed.  As landscapes are converted from wild to managed lands, many pollinators'
habitats may be destroyed.
* There are an estimated 1,330 crop plants grown worldwide for food, beverages, fibers, condiments,
spices, and medicines - about 1,000 of them (75%) require pollination
* Approximately one-third of all foods and drinks are results of pollination, directly and indirectly
* Insect pollination produces $20
billion worth of products every year in the US alone

How can you help protect pollinators?
Pesticide use.  It is important to know that using pesticides affects both the problem insects and the
pollinators.  Careless use of pesticides has played a part in the decreasing number of pollinators.  
The pesticide you spray to kill insects can also kill humming bird nestlings.  If there are not enough
insects to feed on, birds and other creatures that eat the insects can starve to death.  Pollution affects
pollinators too.  
Planting.  You can plant bird and/or insect-friendly habitats around your home to encourage and
support pollinators.  Asters, sunflowers, salvia, bee balm, hyssop, mint, cleome, thyme, poppy,
bachelor's buttons, rosemary, lavender, holly, are just some plants to consider.
Provide homes.  Install "bat houses" and wood block nests for native bees.
Provide water.  Birdbaths, shallow pans of water for butterflies and bees.  Prevent mosquitos by
either changing the water every day or so.



Just about honey bees - from Beekeeping for Dummies, The Beekeepers Handbook, The Hive
and the Honey Bee -

Did you know...
* Honey bees visit 5 million flowers to make one pint of honey.
* Honey bees forage up to five miles away from their hives.
* Honey bees fly about 500 miles total in their 5-30 day flight life.
* Honey bees can visit 10 flowers a minute and more than 600 before she returns to the hive.  She
will make 1-29 trips per day.
* A honey bee can carry a load of nectar about the size of a drop from an eyedropper, about 0.5
milliliters, which is about 85% of her body weight.
* 150 pounds of honey equals 13 round-trips to the moon!
* All the workers n a honey bee hive are female.
