How the White House plans to help the humble bee maintain its buzz

By Juliet Eilperin via Washington Post

The humble bee — nuisance, threat, and linchpin of the American food supply — has won over the leader of the free world. And now President Obama is intervening on the bee’s behalf as its habitat dwindles.

On Tuesday, the Obama administration will announce the first National Strategy to Promote the Health of Honey Bees and Other Pollinators, a bureaucratic title for a plan to save the bee, other small winged animals and their breeding grounds. The initiative may feel like the kind of niche interest a second-term president devotes his time to, but scientists say his attention to the busy workforce that sustains many American crops is critical. While bee colonies regularly die off during winter because of stressful conditions, their sharp decline has been called a potential ecological disaster by some environmentalists and academic experts; conservative Rep. Ted Yoho (R-Fla.) described it in an interview as “an essential thing [that] we need to pay attention to.”

The strategy, a copy of which was obtained by The Washington Post, will seek to manage the way forests burned by wildfire are replanted, the way offices are landscaped and the way roadside habitats where bees feed are preserved.

It is also the culmination of a years-long fascination Obama has had with the bee and its worrisome fate.

“I have to say that it is mighty darn lovely having the White House acknowledge the indigenous, unpaid and invisible workforce that somehow has managed to sustain all terrestrial life without health-care subsidies, or a single COLA, for that past 250?million years,” said Sam Droege, a U.S. Geological Survey wildlife biologist and one of the country’s foremost experts on native bee identification…

Pollinator Politics: Environmentalists Criticize Obama Plan To Save Bees

The buzz around bees has been bad lately. As we’ve reported, beekeepers say they lost 42 percent of honeybee colonies last summer.

And it seems that fixing what ails bees is no simple task. Over the past few decades, they’ve been hit by diseases and habitat loss. There’s also increasing evidence that a type of pesticides called neonicotinoids are linked to bees’ decline, too.

This could be bad news for all of us, since bees and other pollinators are critical to our food supply.

Honeybees alone, according to an Obama administration estimate, add $15 billion in value to agricultural crops each year by pollinating everything from almonds and apples to blueberries and squash.

And now the administration has put forth a new action plan to reverse the declines in bees.

A key component is a strategy to restore 7 million acres of bee-friendly habitat that have been lost to urbanization, development and farming.

“It’s a big step in the right direction,” says Nigel Raine, a professor who studies pollinator conservation at the University of Guelph, in Canada.

The idea is to plant many types of wildflowers — in lots of different areas — so that bees have more places to forage and nest. “It’s making sure they have sufficient flowers to feed on,” says Raine — and places to live.

Many environmentalists say restoring bee habitat is a good place to start, but they’re critical that the Obama administration has not taken a harder line in limiting the use of neonicotinoids.

The Natural Resources Defense Council says more urgent action is needed to safeguard our food supply. “To truly save bees and other pollinators, we must drastically cut down on today’s pervasive use of neonicotinoids and other pesticides,” Peter Lehner, executive director of the NRDC, said in a press release.

And a similar message is coming from Friends of the Earth. The White House Pollinator Strategy won’t solve the bee crisis, the group says.

The Environmental Protection Agency announced in April that it is not likely to approve new uses of neonicotinoids, but the plan announced by the administration on Tuesday did not call for restrictions on current uses.

Lisa Archer, who leads the food and technology program at Friends of the Earth, said in a statement: “President Obama’s National Pollinator Health Strategy misses the mark by not adequately addressing the pesticides as a key driver of unsustainable losses of bees and other pollinators essential to our food system.”

The European Union has already moved to restrict the use of neonicotinoids. And as we’ve reported, there are proposals in Canada to limit use of the pesticides, too.

But a leading manufacturer of the pesticides says neonic restrictions are not necessary. “Neonicotinoids — when used according to labeled directions — can be used safely with pollinators,” Becky Langer of Bayer Crop Science told us.

She says the administration’s strategy to restore bee-friendly habitat is a good approach, and points out that Bayer is helping to address this issue with its Bee Care Center and efforts to encourage the expansion of habitat.

Plan Bee: White House Unveils Strategy To Protect Pollinators


By Brian Naylor via NPR.org

There is a buzz in the air in Washington, and it’s about honeybees. Concerned about an alarming decline in honeybee colonies, the Obama administration has released a National Strategy to Promote the Health of Honey Bees and Other Pollinators.

NPR’s Dan Charles says the strategy, despite its rather bureaucratic title, is pretty straightforward: “The government will provide money for more bee habitat and more research into ways to protect bees from disease and pesticides. The Environmental Protection Agency also will re-evaluate a class of insecticides called neonicotinoids … which are commonly used on some of the most widely planted crops in the country.”

As NPR’s Allison Aubrey has reported:

“Scientists have shown that a range of factors — from climate change to viruses to loss of habitat — are contributing to the global decline in bee health.

“And two new studies published in the journal Nature add to the evidence that overuse of neonicotinoid pesticides may also be contributing to the decline of bees.

“Neonics, as they’re known for short, have become among the most widely used insecticides in the world. The pesticide is coated onto the seeds that farmers plant to grow their crops. These pretreated seeds are used extensively in corn, soy and canola crops. In fact, it’s estimated that treated seeds are used in more than 95 percent of the U.S. corn crop.”

The White House strategy aims to reduce honeybee colony losses during the winter to no more than 15 percent within 10 years. It’s also concerned with the monarch butterfly, another species in decline. The government wants to increase the Eastern population of the monarch to 225 million butterflies occupying an area of approximately 15 acres in the insect’s Mexico wintering grounds. And it sets a goal of restoring or enhancing 7 million acres of land for pollinators over the next five years. The strategy is the work of the White House Pollinator Health Task Force, an Obama administration initiative launched last year. President Obama has taken a personal interest in the plight of the honeybees. There is a beehive in the White House garden, the honey from which is an ingredient in the White House beer recipe. (If you’re interested in a good buzz.) Critics, however, say the White House strategy doesn’t go far enough. Friends of the Earth issued a stinging rebuke to the administration’s plan, charging that it “failed to adequately address the impact of pesticides, including neonicotinoid insecticides on bees and other pollinators.” Puns aside, it’s a serious issue. According to The Washington Post:

“Over the past five years, winter losses of commercial honeybee colonies have averaged roughly 30 percent. A consortium of universities and research laboratories announced last week that beekeepers lost 42.1 percent of their colonies between April 2014 and 2015, an 8 percent spike from the previous year, and that the number of summer deaths exceeded winter deaths for the first time since the survey began in 2010.”

The Obama administration says honeybee pollination adds more than $15 billion in value to agricultural crops each year. [Read the original article via NPR.org]

READ: Teaching Children to Love Bees, Not Fear Them

By JENNIFER BERNEY via parenting.blogs.nytimes.com

Several years ago, reports of the declining bee population inspired my partner to keep bees in our yard. Her reasons were mainly practical—not only did she want to support the vanishing bees, she hoped our plum trees might increase their yield. But it took less than one season for my partner to fall in love, and over time the number of hives in our backyard has multiplied from two to 10. At my house this week we know that spring has arrived because my 2-year-old points out the window and yells excitedly: “Bees!”

I consider both of my children lucky to know the honeybees so well. Living with a beekeeper has afforded me a chance to observe how children interact with bees. From what I’ve seen so far, they fall into two distinct camps: those who are fascinated, and those who are afraid.

There are kids who watch in wonder as the honeybees land on the stones in our birdbath and drink water through their delicate tongues, and there are kids who cover their hair with their hands and run away screaming. There are kids who knock on our door to buy a jar of honey and ask to see our bees, and there are kids who will poke a long stick through our fence and bang it against the roof of a hive.

I worry that the child who runs from bees in fear will grow up to be the adult who spots a healthy swarm in her backyard and sprays it with insecticide. I worry that the child who bangs on a hive roof will grow up to be the teenager who knocks over a neighbor’s hive in the middle of the night. These are two kinds of transgressions that happen often in my community, and they are undeserved. Unlike the many varieties of wasps, bees are gentle creatures. They pollinate our crops, make honey, and rarely sting unless provoked.

In recent years, beekeepers have continued to report high annual losses. An annual survey of beekeepers conducted by a partnership that includes the United States Department of Agriculture, released Wednesday, suggested both that significant losses in colonies continue, and that the loss rate in summer has increased. We compensate for this by breeding and replacing our lost colonies year after year. Scientists are no longer concerned that the honeybee’s extinction is imminent, but we are not yet off the hook. The disappearing bees have reminded us that our survival is interdependent. We live in collaboration with other species. A child who squashes bees or runs from them is a child who hasn’t yet learned their value, and it’s our job to teach them.

This might begin by teaching our children what a honeybee looks like. Before my partner brought home our first colony of bees, I was like many adults in that I could not distinguish a honeybee from a bumblebee, and had only the vaguest notion that wasps were a different species entirely. The yellow jacket who is harassing you at the end of summer, trying to take a bite of your ham sandwich, has little in common with the honeybee who is gathering pollen and nectar. Children are capable of making this distinction; like adults, they just need a little guidance.

Teaching children to value the honeybee might also include explaining the phenomenon of swarming, which, contrary to popular belief, is not an angry behavior. Honeybees swarm when their colony has grown healthy enough to divide in two. One half of them remain in the hive to welcome a new queen, while the other half leaves in search of a new home. They fill their bellies with nectar and travel in a cluster to shelter their old queen. The sight of a cluster of bees on a branch in a yard or a park is an opportunity for observation, a lesson about the intelligence of the insect world.

And that is the real lesson the bees offer: as smart as we humans are, we don’t know everything. At my house we can dance to Beyoncé in the living room, but we can’t wiggle our butts in a sequence so precise that it communicates the location of a nectar source three miles away. Bees can.

My partner has a practice that many beekeepers would find silly. Though a typical worker bee lives for only six weeks, in the evening my partner often picks up bees who have grown cold and fallen just outside the entrance to their hive. She collects them in a jar, brings them inside our house to warm them up and later, once they are restored, she returns them to their home. I used to tease her about this. Bees are members of a complex system. They are not individuals, and it struck me as foolish to attend to them as such. But then last week I saw my 6-year-old son crouch in front of a hive at dusk to gather languishing bees in his small hand. In that moment I realized what the bees had taught him — it’s the very lesson we all need to learn: that every small part of the system counts for something.

READ: Backyard beekeeping could soon be legal in Los Angeles

POSTED BY JOHN SCHREIBER via mynewsla.com

Beekeeping would be legal in the backyards of Los Angeles homes under regulations to be considered soon by a City Council committee.

The proposed rules — approved by the city planning commission this week and now headed to the council’s Planning and Land Use Committee — would allow hobbyists and others interested in small-scale beekeeping to maintain hives in single-family residential settings.

Beekeepers would need to adhere to certain restrictions under the proposed rules. No more than one hive would be allowed for each 2,500 square feet of space, and there must be a 5-foot buffer between the hive and the front, side and rear lot lines of the property.

Hives also must be at least 20 feet away from public right of way or a private streets and cannot be kept in the front yard, according to the rules.

The proposed ordinance also calls for hives to be surrounded by a 6-foot wall, fence or hedge, or else it must be set 8 feet above ground, so that the bees would be encouraged to stay above “human-level.”

The bees also must have access to a nearby water source within the beekeeper’s property so that the bees would not need to travel outside to look for water.

If the City Council approves the ordinance, Los Angeles would join Santa Monica in legalizing so-called “backyard” or “urban” beekeeping. The hobby also is allowed in other urban areas such as New York City and Denver.

The Los Angeles Planning Department and the city attorney created the proposed rules after the City Council ordered a study last February into ways to legalize backyard beekeeping.

The council action came in response to a growing chorus of Angelenos advocating for “urban beekeeping,” including from some residents in the Mar Vista area who said increased beekeeping helps to fight a troubling, downward trend in the bee population that could threaten the health of local agriculture.

Councilman Paul Koretz, who supports legalizing urban beekeeping, said last year the state has been losing a third of its bees a year since 2006, threatening California’s avocado and almond industry.

Some council members voiced concerns, however, that the bees could pose a danger to residents, with Councilman Bernard Parks referring to a National Geographic documentary entitled “Attack of the Killer Bees,” about a dangerous variety of bees that appear to be encroaching into southern United States.

Planning officials who consulted bee experts over the last year wrote in a recent city report that the variety of honey bees used in beekeeping are “non-aggressive,” but they may “sting in self-defense of their hive if it is approached.”

The report adds that when the bees leave their hives to collect food — potentially coming in contact with humans — they “do not become defensive or aggressive or have reason to sting.”

The report also notes Los Angeles already averages about 8 to 10 feral bee hives per each square mile. The addition of backyard honey bees would not cause a shortage of bee food supply in the city due to the area’s steady climate, but if there were a shortage, the feral populations would likely leave the area to find alternative sources of food supply, according to the bee experts consulted by planning officials.

READ: Sweet! Los Angeles is closer to legalizing beekeeping

Rob McFarland holds a beehive of honeybees. (Los Angeles Times)

By KERRY CAVANAUGH via LA Times

Los Angeles is getting closer to legalizing backyard beekeeping and the proposed ordinance couldn’t come at a better time.

Professional beekeepers reported this week that 42% of their honeybees died in the last year, and, for the first time, they lost more bees during the summer than the winter. That’s surprising and worrisome because bees typically suffer in the cold weather, but fare better during the warm pollination season. And it underscores fears that parasites, pesticides and farming practices might be weakening the bee population, which is essential for pollinating the nation’s food crops.

Backyard beekeeping can’t replace commercial beekeeping operations, but the urban honeybees may help replenish the diminishing supply, or provide disease-resistant genes that can be introduced in the commercial bee lines. The more healthy bees in the environment, the better for everyone.

Current city law prohibits beekeeping, except on land zoned for agricultural uses. The proposed ordinance, approved Thursday by the city Planning Commission, would allow beekeeping by right in single-family neighborhoods. The resident would need to register as a beekeeper with the Los Angeles County agriculture commissioner, have no more than one hive per 2,500 square feet of lot, keep the hives at least five feet from the neighbors’ yards and 20 feet from the street or sidewalk and keep a source of water for the bees so they don’t seek water from the neighbors’ swimming pool or bird bath. There’s no pre-approval needed, but the city will respond to complaints and if residents break the rules or can’t manage their bees, the city can revoke the right to keep hives.

The City Council still needs to OK the new backyard beekeeping policy before it can take effect, but city leaders have been supportive of urban agriculture. And why not? L.A. has the ideal climate and long growing seasons. The city has hillsides, vacant lots and yards that can support small farms and hobby farmers. A vegetable garden or orchard is a more productive use of our precious water supply than a green lawn. And more fruits and vegetables grown locally mean less produce has to be trucked and shipped over great distance, meaning fresher food and less fossil fuels burned in transport.

READ: A Sharp Spike in Honeybee Deaths Deepens a Worrisome Trend

NY TIMES

A prolonged and mysterious die-off of the nation’s honeybees, a trend worrisome both to beekeepers and to farmers who depend on the insects to pollinate their crops, apparently worsened last year.

In an annual survey released on Wednesday by the Bee Informed Partnership, a consortium of universities and research laboratories, about 5,000 beekeepers reported losing 42.1 percent of their colonies in the 12-month period that ended in April. That is well above the 34.2 percent loss reported for the same period in 2013 and 2014, and it is the second-highest loss recorded since year-round surveys began in 2010.

Most striking, however, was that honeybee deaths spiked last summer, exceeding winter deaths for the first time. Commercial beekeepers, some of whom rent their hives to farmers during pollination seasons, were hit especially hard, the survey’s authors stated.

“We expect the colonies to die during the winter, because that’s a stressful season,” said Dennis vanEngelsdorp, an assistant entomology professor at the University of Maryland who directs the survey for the bee partnership. “What’s totally shocking to me is that the losses in summer, which should be paradise for bees, exceeded the winter losses.”

Bees are not in danger of extinction, but their health is of major concern to agriculture, where honeybees’ pollination services are estimated to be worth $10 billion to $15 billion a year.

Nobody knows with certainty why honeybee deaths are rising. Beekeepers once expected to lose perhaps 10 percent of their bees in an average year. But deaths began to spike in the middle of the past decade, when a phenomenon in which bees deserted their hives and died en masse, later named colony collapse disorder, began sweeping hives worldwide.

Those mass die-offs have abated somewhat in recent years, experts say, but colonies remain in poor health, and overall death rates remain much higher than in the past.

Dr. vanEngelsdorp said increasingly poor nutrition could be a factor in the rising summer death rate. Rising crop prices have led farmers to plow and plant millions of acres of land that was once home to wildflowers; since 2007, an Agriculture Department program that pays farmers to put sensitive and erosion-prone lands in a conservation reserve has lost an area roughly equal to half of Indiana, and budget cuts promise to shrink the program further. Dr. vanEngelsdrop and other scientists cite two other factors at work in the rising death rate: a deadly parasite, the varroa mite,and pesticides.

In recent years, some experts have focused on neonicotinoids, a class of pesticides used almost universally on some major crops in the United States. The European Commission has banned the use of three variants of the pesticide on flowering plants, citing risks to bees, and questioned whether they should be used at all.

The Environmental Protection Agency said last month that it was unlikely to approve any new uses of the pesticides until more tests on the risks to bees and other pollinators have been completed.

Neonicotinoid manufacturers say that the pesticides are much safer than others they have supplanted, and that in any case, they are safe when used according to instructions.

In a news release, an entomologist at one of the major neonicotinoid manufacturers, Bayer CropScience LP, called the survey results good news because wintertime bee deaths appeared to have stabilized at a lower rate than in the past. The entomologist, Richard Rogers of the company’s Bee Care Center in Research Triangle Park, N.C., said that scientists had yet to establish a normal range for summer bee deaths.

The annual survey released on Wednesday did not directly address the causes of honeybee deaths. But it said varroa mites were a much bigger problem among so-called backyard beekeepers, who keep fewer than 50 hives, than among commercial beekeepers, who are probably on higher alert for deadly infestations.

The survey’s authors called the spike in summer honeybee deaths troubling, noting that in the past, more bees have died during the winter months than in good weather.

The Bee Informed Partnership has collected data on summer bee deaths since 2006, and it expanded its survey to cover winter deaths in 2010. The surveys are financed largely by the Agriculture Department.

READ: Brood diseases and lagging bees

by HoneyLover Susan Rudnicki

Spring is the time of year when bees go into high gear to get ready to do their instinctive reproductive act of procreation—swarming. A colony grows to fill its space, replacement queens are drawn and nurtured, and the final event is a leaving from the mother hive of about 50% of the workers and the old queen. These bees will attempt to found a new colony somewhere else and begin the cycle again. During this build up in Spring we urban beekeepers must watch carefully for the signs of swarm preparation and guide it so that a swarm is not the outcome—in the city such swarms are not appreciated by the general public living in close proximity to us.

I have now been keeping bees almost four years and am getting a better feel for the rhythm of the growth cycle in a colony. We have mild winters in Los Angeles, so the Spring brooding up period often begins in January. This means we will begin seeing drones and drone brood, new brood comb being drawn, and a general increase in the number of bees and activity of the queen.

However, early this year, two of my hives at the house were not showing these changes and I really began to notice by February. It seemed they were just staying in a holding pattern—no new comb was being drawn and, at first, this was the most noticeable issue. By the beginning of March, I was seeing sac brood, perforated cappings (small holes in the brood caps), lots of uncapped pupae in the purple eye stage, dried up “mummies” of brood in cells, and some cells of open brood with watery goop that may have been European Foul Brood.  There were also some adult bees with DWV, or deformed wing virus. The wings of the bee are twisted little stumps or thread-like and useless. The colonies had plenty of stored honey and many frames of bee bread. Together, these conditions and the different maladies of the larvae and pupae are sometimes lumped under the name “Bee Parasitic Mite Syndrome”  which describes diseases vectored by the activities of the varroa mite.

Here is a website entry detailing what I was seeing—

Information compiled by Beekeeper Lonnie E. Campbell of The Loudoun Beekeepers Association.

Bee Parasitic Mite Syndrome was first named by The Beltsville Bee Lab to explain why colonies infested with both varroa mites and tracheal mites were not thriving. BPMS was first reported by European beekeepers whose colonies were already stressed by varroa mites. Colonies that are apparently very healthy and productive suddenly experience a sudden decrease in adult population often resulting in the total loss of the colony. Plenty of food stores are often present, but very spotty and unhealthy brood are observed.

I began searching my readings and books to find out what I might do to help these two formerly thriving hives (one hive is 5 mediums, the other 2 deeps and 3 mediums). I wanted to support them before their population dropped too much that they would be weakened beyond recovery. I saw on inspection March 22 that very little open brood was present and no eggs. One queen was seen (in the biggest colony) but in the other I didn’t find the queen.

Michael Bush’s book offered the best information for this situation that I could find. A brood break, or a cessation of egg laying by the queen, is one of the best responses for breaking the cycle of the pests and diseases that may afflict a hive. By denying the pathogens a food source the disease cycle is automatically broken. One way of doing this is to find and kill the queen and then introduce a new queen. Another way is to dispatch the queen and let them raise another one. By the time the new queen is laying, the brood break will have cleansed the disease cycle.

But the method I thought I would settle on was the use of a push in cage. This is a small confinement cage made out of eighth inch hardware cloth that holds the queen on the face of a frame for a period of time to prevent her laying eggs in the normal pattern. It is just a shallow 3 sided box of wire, 5 X 10 inches, pushed into the face of the wax comb. You try to place it in a zone with some honey cells, some emerging brood, and some open cells—all of these to serve the needs of the confined queen.

On March 28, after preparing two cages and getting my mind clear about what I was going to do, I opened up the first hive to start my search for the queen. I had at hand a  good tool for safely catching a queen— a “hair clip” catcher.

However, I soon saw that something better than my plan had already occurred. The frames that had lacked any eggs or open brood were now completely filled with eggs! The queens had stopped laying eggs by their own accord and interrupted the brood cycle of the diseases and varroa that had been afflicting them. I was very excited that the queens and their workers seemed to have a inborn strategy to get over their problems. My notes to Michael Bush to report this were confirmed in his answer here:

         Yes, the bees often do a brood break to resolve the issues.  Sometimes it’s done by dispatching the old queen and sometimes she just shuts down. EFB usually clears up on it’s own when whatever stress was the cause is relieved.  Usually by a flow in a dearth.

And this one:

It doesn’t always work out well, but then interfering doesn’t always work out well either.

“Our attentions may be useful to them but are oftener noxious to them; thus far goes our interference.” –Francis Huber (in a letter to Elisa)

“…without the foresight, or rather the astonishing presence of mind of the bees, who always do at the proper time what needs to be done…” –Francis Huber (in a letter to Elisa)

So, there we have it. Another beek lesson learned!

READ: Urban beekeeping becomes therapy for at-risk communities

By North By Northwest, CBC News

Julia and Sarah Common started their urban beekeeping non-profit organization in 2012

Bees play an important role in the ecosystem, as they pollinate plants and produce honey, but it turns out they can also play a therapeutic role for humans.

Since 2012, Julia Common and her daughter Sarah have been engaging at-risk communities in urban beekeeping through their non-profit organization, Hives for Humanity.

Mother and daughter started by placing a colony of bees at a community garden on Vancouver’s Downtown Eastside.

“The community really quickly took ownership of that hive and responsibility for the protection and care of this living, breathing colony of working insects that are just this inspiration to everyone who sees them,” Sarah told North By Northwest‘s Sheryl MacKay.

The Commons say beekeeping is therapeutic because it brings people together and the responsibility gives them a sense of self worth and community pride.

“At the beginning, we thought it was the beekeeping, but then from beekeeping, other things come,” said Julia.

“The bees have wax, someone needs to [process] the wax. Other people come forward who want to help with equipment maintenance.”

Hives for Humanity now has almost a hundred hives placed in community gardens, the rooftops of single room occupancy hotels and people’s backyards.

“No matter where you are, people take great pride in taking care of the bees, keeping them safe,” said Julia.

“Everyone from kindergarten right up to somebody who is 92 realizes bees are threatened and they just feel wonderful that they’re playing their [part].”

READ: Bees prefer the buzz of a town

Bees prefer the buzz of a town: Urban sites found to have more species than rural areas

By Fiona Macrae via dailymail.co.uk

  • Agriculture and mass crops blamed for decline of bee numbers 
  • Towns and cities have wider variety of plants and flowers in autumn
  • Pesticides, climate change and disease causing bee numbers to fall 

We think of them as thriving in wildflower meadows and rolling fields. But new research suggests Britain’s bees are happier near towns and cities.

A study of wildlife sites across four English counties has found that most are home to fewer species of bee today than they were in the past.

It found that the expansion of farmland has actually been more damaging to Britain’s bee population than the concreting over of the countryside for housing.

Reading University researcher Deepa Senapathi believes intensive agriculture is to blame.

While the gardens, parks and churchyards of towns and cities provide bees with a variety of plants to forage on and an extended flowering season, popular crops such as oilseed rape only bloom for a few weeks.

She said: ‘While concreting over the countryside may appear to be bad news for nature, we’ve found that progressive urbanisation may be much less damaging than intensive agriculture.

‘Urban areas may benefit bees more than farmland by providing a wide variety of flowering plants, providing a cosmopolitan menu for insects from spring through to autumn.

‘Over the past century rural landscapes in Britain have become increasingly dominated by large expanses of monoculture – the growing of a single type of plant, which has helped boost crop production.

‘But without a mixture of habitat and food sources, rural areas can sometimes be little better than green deserts for biodiversity.

Scientists around the country are trying to work out why populations of bees and other insects are plummeting.

Pesticides, climate change and disease may, like intensive farming, be playing a role.
