Florida sending Bees West as California Almond Growers Face Pollination Crisis
February 15, 2013
As almond trees begin to blossom in California’s San Joaquin and Sacramento valleys, Florida bee keepers loaded semi-trailers with bee colonies to help pollinate the 800,000 acres of groves, according to David Westervelt, Apiary Inspection assistant chief of the Florida Department of Agriculture and Consumer Services Division of Plant Industry (FDACS-DPI).
“California has only 500,000 colonies to pollinate almonds,” Westervelt said. “Florida beekeepers are sending 90,000 to 100,000 colonies. But it’s estimated about 1.6 million colonies are needed.” FDACS-DPI inspectors are certifying each truckload to meet California requirements. The possibility of transporting fire ants is a major concern.
California almond producers have paid Florida bee keepers for pollination services in previous years. This year the need has become more acute due to losses of bees over the winter. Some California bee keepers reported 90-100 percent of their colonies had died.
“Last year was not a good year for honey production in the United States,” said Extension apiculturist Eric Mussen of the UC Davis Department of Entomology, “and it could be one of the worst honey production years in the history of nation, although it’s been pretty rough in some of the previous years. Usually when we’re short of nectar, we’re short on pollen, and honey bees need both. So, 2012 was a bad year for bee nutrition.”
Growers pay well — an average of $150 but up to $220 per colony for pollination, but a good nut set also depends on mild, warm temperatures and relatively high humidity. By February 14 the average almond orchard in California is in full bloom, but some bloom earlier or later, depending on the cultivar and the weather. An almond orchard blooms for about two weeks,
After completing their pollination duties in California around March 15, most of the bees will return to Florida where their services are required by blueberry producers and other growers.
“Once they’ve returned to Florida, the bee keepers will begin moving their colonies steadily north as the weather gets warmer, pollinating crops along the way,” Westervelt said. “Florida bee keepers make a great contribution to U.S. agriculture, but the overall problem is, there just aren’t enough bees anywhere in the country.”
Colony collapse disorder (CCD), a mysterious malady that was first noticed in the winter of 2006, has exacerbated the problem by killing off one-third of the nation’s bee population each year. Some bee keepers in California reported losses of 90 to 100 percent this winter.
