New backyard beekeeping regulations in Santa Rosa move forward

Draft regulations

Santa Rosa has released a draft set of rules that would legalize backyard beekeeping, a proposal spurred by a young boy and his family who helped champion residents’ rights to raise bees in the city.

The new regulations would set standards for colony limits, hive placement and maintenance as well as guidelines for small-scale honey sales.

The ordinance also would require beekeepers to display their name and telephone number at the property in case of any issues. It outlines enforcement provisions if beekeepers violate the code.

Community members for the better part of a year have urged the city to update its zoning code after then 9-year-old Nicholas Bard and his family were ordered to relocate their hive — a decision that has since been rescinded as staff worked on the new policies.

Return of long-lost bees creating a lot of Presidio buzz

Peter Fimrite, SAN FRANCISCO CHRONICLE

The sudden appearance of buzzing insects around Brian Hildebidle’s feet as he surveyed a dune restoration project in the Presidio last week startled him and prompted alarming visions of volunteer workers fleeing from angry yellow jackets.

The stewardship coordinator for the Presidio Trust was about to run when he noticed the insects were a grayish color and swirling in a strange pattern close to the ground.

“I was really curious because I had never seen that flying pattern,” said Hildebidle, who leads volunteers on weekly weed-pulling and planting expeditions and is quite familiar with the park’s bug denizens.

The insects, which he said numbered in the hundreds, turned out to be silver digger bees, a rare sand-loving species that had not been seen in San Francisco in significant numbers for the better part of a century.

Field tests show how pesticides can wreak havoc on honeybees

Mira Abed, THE LOS ANGELES TIMES
Humans are big fans of bees. We rely on them to pollinate crops like almonds, watermelons and apples.
But bees probably aren’t big fans of humans — at least, not of our agricultural practices.In particular, they ought to be offended by our fondness for a widely used class of pesticides called neonicotinoids (neonics, for short).
Studies in the lab have shown that some doses of neonics are outright lethal to many bees and that even sub-lethal doses can shorten a colony’s lifespan and harm its overall health. Results have been similar in small-scale field studies.
Still, exactly how these pesticides, which are applied to seeds before planting, would affect bees in the real world remains something of a mystery. Scientists have been locked in a fierce debate over how much — and for how long — bees encounter these pesticides in their daily lives. After all, the conditions in a field are far more complex than those in a lab.
Now, two studies published side by side in the journal Science attempt to answer this contentious question.
One of the studies was conducted in Canada. It combined large-scale field work and laboratory experiments to better understand real-world neonic exposure levels and their effects on honeybees.
The other was conducted in large fields in Hungary, Germany and the U.K. Its goal was to understand how the effects of neonics vary between countries and how exposure during the flowering season affects the long-term health of a bee colony.

Pesticides damage survival of bee colonies, landmark study shows

Damian Carrington, THE GUARDIAN

Prof David Goulson, a bee expert at the University of Sussex, UK, said: “In the light of these new studies, continuing to claim that use of neonicotinoids in farming does not harm bees is no longer a tenable position. In my view we should also consider the bigger picture; the current model of farming based on huge monocultures treated with dozens of pesticides is causing devastating environmental harm, undermining vital ecosystem services that keep us all alive.”

Widely used insecticides damage the survival of honeybee colonies, the world’s largest ever field trial has shown for the first time, as well as harming wild bees.
The farm-based research, along with a second new study, also suggests widespread contamination of entire landscapes and a toxic “cocktail effect” from multiple pesticides.
The landmark work provides the most important evidence yet for regulators around the world considering action against neonicotinoids, including in the EU where a total ban is poised to be implemented this autumn. The insecticides are currently banned on flowering crops in the EU.
The negative impacts found varied across different countries, leading the pesticide manufacturers to question whether the results of the research, which they funded, were real. The new research is published in the prestigious peer-review journal Science.

How rising CO2 levels may contribute to die-off of bees 

Lisa Palmer, YALE ENVIRONMENT 360
Specimens of goldenrod sewn into archival paper folders are stacked floor to ceiling inside metal cabinets at the Smithsonian National Museum of Natural History. The collection, housed in the herbarium, dates back to 1842 and is among five million historical records of plants from around the world cataloged there. Researchers turned to this collection of goldenrod — a widely distributed perennial plant that blooms across North America from summer to late fall — to study concentrations of protein in goldenrod pollen because it is a key late-season food source for bees.
The newer samples look much like the older generations. But scientists testing the pollen content from goldenrod collected between 1842 and 2014, when atmospheric concentrations of carbon dioxide rose from about 280 parts per million to 398 ppm, found the most recent pollen samples contained 30 percent less protein. The greatest drop in protein occurred from 1960 to 2014, when the amount of carbon dioxide in the atmosphere rose dramatically. A field experiment in the same study that exposed goldenrod to CO2 levels ranging from 280 to 500 ppm showed similar protein decreases.
More than 100 previous studies have shown that elevated levels of atmospheric carbon dioxide decrease the nutritional value of plants, such as wheat and rice. But the goldenrod study, published last month, was the first to examine the effects of rising CO2 on the diet of bees, and its conclusions were unsettling: The adverse impact of rising CO2 concentrations on the protein levels in pollen may be playing a role in the global die-off of bee populations by undermining bee nutrition and reproductive success.
“Pollen is becoming junk food for bees,” says Lewis Ziska, a plant physiologist at the U.S. Department of Agriculture’s (USDA) Research Service in Maryland and lead author of the study. The study itself concluded that the decline of plant proteins in the face of soaring carbon dioxide concentrations provides an “urgent and compelling case” for CO2 sensitivity in pollen and other plant components.
Elevated CO2 levels affect plant physiology by enabling the plant’s starchier parts to grow faster and bigger, since atmospheric carbon dioxide is a building block for plant sugars. For goldenrod, this growth essentially dilutes the plant’s total protein, From 2006 to 2011, losses from managed honeybee colonies averaged 33 percent per year in the U.S. rather than concentrating it in the grain, which makes a starchier pollen.
“I knew there was work done on insects about how rising CO2 would reduce the protein content of leaves, and so insects will need to eat more leaves to get the same amount of protein,” says Ziska. “But until now, we didn’t know about how CO2 affects protein content in pollen.” The study is a synthesis of the knowledge about what is happening to bees and how CO2 impacts the quality of plants, and it brings those two disparate ideas together.
A number of new and accumulating pressures are threatening bee populations. From 2006 to 2011, annual losses from managed honeybee colonies averaged 33 percent per year in the United States, according to the USDA. Beekeepers have had to replace 50 percent of their colonies in recent years. Factors such as mite outbreaks and the use of neonicotinoid pesticides have been implicated in so-called “colony collapse disorder.”

How to keep honeybees

Rene Ebersole, MODERN FARMER

You can hardly say “honeybee” anymore without hearing the reverb “colony collapse disorder.” Back in 2006, American beekeepers began reporting staggering losses, ranging from 30 to 90 percent of their hives. Since then, the alarming phenomenon—in which adult bees disappear, leaving the brood behind to die—has afflicted Europe as well. And honey’s far from the only reason to care. In America alone, the pollinators enable the production of roughly 90 commercial crops, according to the United States Department of Agriculture. Without honeybees, some of the foods we eat, like almonds, could become extinct; the cost of others, such as cherries and avocados, would likely skyrocket. A decade after the disorder first surfaced, scientists have yet to identify a definitive culprit.
Meanwhile, U.S. citizens have taken up the cause, establishing hives in backyards, atop roofs, at restaurants, even on the White House lawn. Bee Culture magazine, already a publication with a narrow focus, recently launched a spin-off targeted even more specifically at beginners. Williams-Sonoma, ostensibly a kitchenware retailer, started selling beekeeping equipment in 2012. Even Costco carries hives these days.
Longtime beekeeper Rob Keller of Napa, California, should not be counted among the recent converts. He does, however, have the current apiary craze to thank for his success. Since launching the Napa Valley Bee Company in 2008, the 52-year-old has helped more than 100 clients—individuals and businesses, including Alice Waters’ legendary Chez Panisse—start and maintain honeybee colonies. “I can’t just sell my bees and walk away. I know that queen’s mother and her mother’s mother. I’d rather guide someone through all four seasons,” Keller explains. “It’s weird, man. It’s like I’m turning into, not a crazy cat lady, but a crazy bee guy. I have the utmost respect for this six-legged insect.”

Create a garden both you and Sonoma County bees will love 

Meg McConahey, THE PRESS DEMOCRAT
There are a lot of practical and ecological reasons to turn your landscape into a way station and home for bees. In fact, the list of advantages is so compelling it may dramatically change how you see and use the space around your home.
Not only is a bee-friendly garden organic and sustainable, but a garden humming with bees will lead to a more bountiful harvest of larger and healthier fruits and vegetables. It will also attract other beneficial insects that will go after garden pests as well as provide habitat for butterflies, moths, bats, hummingbirds and other wildlife.
But on an even more global scale, bees provide a critical link in the world’s food chain by facilitating the fertilization of more than 70 percent of the world’s plants, says acclaimed North Coast garden designer Kate Frey. This includes many edibles, from nuts and fruits to tomatoes, peppers, berries and even some root crops like carrots and beets.
For all their virtues, bees have been suffering, not only from the mysterious Colony Collapse Disorder in which the worker bees in hives can die off or desert, but from new pathogens, parasites, pesticides on the flowers they visit, herbicides that wipe out the plants they depend on and pests. In addition, habitat is disappearing due to development and monoculture — vast acreage of the same crop — that leave no sustenance for bees.
The good news is that even urban and suburban homeowners can help the bee cause and without sacrificing beauty, says Frey, co-author with San Francisco State University biology professor Gretchen LeBuhn of “The Bee-Friendly Garden” (Ten Speed Press, $19.99).
