As beekeepers we are flooded daily with questions
from concerned consumers about what is happening to the bees. So we
felt it necessary to give a brief explanation, (as brief as possible,
anyway.)
Scientists and beekeepers across the USA are working hard to uncover
the reasons behind the mysterious disappearance of honey bees. Over
30% of the nations colonies died over the winter of 2006/2007 with
countless more dying over the 2007/2008 season. However, it seems to
be affecting some beekeepers more severely than others. Whether you
are a beekeeper or not this disorder is very troubling. It has potentially
far reaching effects for all of us. What do we stand to lose? 1/3 of
everything we eat is dependant on honeybee pollination. That translates
to over 15 billion dollars (to about 130 crops) a year in the US. Not
to mention the loss of the wonderful and incomparable bounty of the
hive itself. Some crops that require or benefit dramatically from honey
bee pollination include almonds, apples, blueberries, cashews, cherries,
cucumbers, peaches, pears, peppers, pumpkins, raspberries, soybeans,
squash, strawberries and sunflowers. Honey bees also pollinate most
wild and native plants in our ecosystem. Helping to feed and support
our animal wildlife. Clearly, honey bees are major players in the food
supply and ecosystem. By February 2007, the syndrome, which is characterized
by the disappearance of all adult honey bees in a hive while immature
bees and honey remain, had been named “colony collapse disorder” (CCD).
The question is, “Just what is causing CCD?” This is a
very good question without a simple answer. Some potential causes have
been named: environmental stresses (which include climate change and
pesticides), pathogens, parasites and management stresses. Many scientists
believe that CCD is likely due to a combination of factors. This makes
investigating the cause of CCD especially complex. Over the last few
years our nation has experienced climate change, such as intensified
storms, floods and droughts. Whether caused by human activities or
not these changes are affecting the honey bees. Simply put, in drought
conditions, plants do not yield the vital nectar/pollen for the bees
and in extremely wet conditions the bees cannot fly to avail themselves
of the nectar/pollen. These large variations of weather stress the
colony. Wayne Esaias, a NASA scientist, is conducting research on how
climate change is affecting honey bees. Esaias believes that a beehive’s
seasonal cycle of weight gain and loss is a sensitive indicator of
the impact of climate change on flowering plants. According to his
honey bees, big changes are underway. The most important event in the
life of flowering plants and their pollinators—flowering itself—is
happening much earlier in the year than it used to. Changes in the
timing of honey production are a sign that climate change is affecting
flowering trees.
