“Dinosaurs, robots and honeybees. I don’t know why, but everyone is fascinated,” says Richard Glassborow, chair of the London Beekeepers’ Association (LBKA). When it comes to beekeeping, what was as soon as a distinct segment passion has flourished, particularly in Britain’s cities.
But there is rising concern from scientists and skilled beekeepers that the huge numbers of honeybees, mixed with an absence of pollinator-friendly areas, could possibly be jeopardising the well being and even survival of a few of about 6,000 wild pollinators throughout the UK. Last 12 months, Kew Gardens’ State of the World’s Plant and Fungi report warned: “Campaigns encouraging people to save bees have resulted in an unsustainable proliferation in urban beekeeping. This approach only saves one species of bee, the honeybee, with no regard for how honeybees interact with other, native species.”
“The general public know about honey; they know it comes from a bee. I think for most people, that’s it. That’s bees,” says Prof Jane Memmott at Bristol University. “Actually, there is the huge swathe of native biodiversity – around 270 species of solitary bee and 25 species of bumblebee – that really need our help.”
Alarmed at the variety of beehives in London greater than doubling over a 10-year interval, with an estimated 7,400 hives in Greater London, the LBKA stated earlier this 12 months: “The prevailing ‘save the bees’ narrative is often based on poor, misleading or absent information about bees and their needs. It can imply that keeping honeybees will help bees, which is not necessarily the case.”
Glassborow provides: “We have to change the narrative. People think getting honeybees is going to save bees. It isn’t. This is quite a sensitive issue for a beekeeping association to take on … [but] this is coming from the membership, it’s not something that a few people are campaigning for.”
“Honeybees are not in decline; they are probably the most numerous bee on the planet,” says Andrew Whitehouse from insect conservation charity Buglife. While the UN’s Food and Agricultural Organization reviews there are greater than 90m honeybee hives globally, many rarer native pollinators are in more and more precarious positions.
“Our wild pollinators are in serious trouble. Across the board we are seeing a loss of the abundance and the diversity of pollinating insects,” provides Whitehouse. “We are seeing threatened species becoming more threatened and more rare. We are seeing some species that we know are really on the brink of extinction in the UK.
“The large mason bee used to be found in southern England and Wales; that’s now only found on a single site in north Wales. The six-banded nomad bee which used to be fairly widespread is now only found on a single site in Devon. When you’re only on single sites there is a real risk of extinction.”
Prof Phil Stevenson, lead writer of the Kew report, argues that the bees native to our shores are a few of the most various and spectacular in the world – the equal of a ring-tailed lemur or Sumatran rhinoceros wandering via our gardens. “Bees are a rather strange organism in that the greatest diversity is in the temperate zones,” says Stevenson. “With almost every other creature, you have got this peak of diversity in the tropics where it’s warm, wet and highly diverse. Bees are more adapted to more temperate climates, so the greatest diversity is in the belts across Europe and North America.”
Global elements are contributing to the catastrophic stresses and strains endured by wild pollinators, a gaggle that features not solely bees however bats, flies, moths, wasps, birds, butterflies and beetles. “It’s climate change; it’s lack of floral resources in the countryside. We have lost a third of the nectar in the countryside since the 1950s. There are diseases, there is habitat loss, there are pesticides,” says Memmott. “All of these things don’t act in isolation either: if you haven’t got enough food you are probably more likely to catch diseases because your immune system isn’t as competent.”
As a results of the challenges in extra historically insect-friendly habitats, city areas have grow to be an more and more very important lifeline for beleaguered pollinators. “We did a big project where we asked how do cities compare with farmland and nature reserves, and actually on average there are more bee species in cities than there are in the surrounding farmlands,” says Memmott. Stevenson provides that greater than 50% of the UK’s bee species have been discovered in London, with 107 in Kew Gardens alone.
“There is a lot of scientific literature that shows urban areas are really important in supporting the abundance of wild pollinators and especially some of those more generalist species,” says Whitehouse. A scarcity of pesticides in city gardens permits extra vegetation to flower, and a warmth island impact can lengthen the flowering season of non-native vegetation that many generalist pollinators are very happy to feed on.
Stevenson says one among the goals of the Kew report was to assess the quantity of vegetation (forage) in a typical city setting and what number of beehives that might moderately be anticipated to assist. “We estimated that a square kilometre of urban landscape in the UK could support seven-and-a-half hives. In some places in London there are over 50,” he says.
Dale Gibson of Bermondsey Street Bees, a industrial beekeeping follow with a spotlight on sustainability, says they’ve decreased their hives in London by a 3rd to alleviate the overpopulation disaster. He explains how the dietary necessities of honeybees could make competitors for scarce meals useful resource extraordinarily fierce.
“Honeybees are very efficient, almost omnivorous consumers of nectar and pollen; they are voracious,” says Gibson. “There is no off button. They will carry on consuming what’s out there as long as it’s out there. Just to stay alive each beehive will consume 250 kilos of nectar and 50 kilos of pollen. If you have a hive of 70,000 bees, that’s 70,000 times four or five cycles over a single season. You are talking about almost half a million bees that have got to be fed.”
Whitehouse provides: “We know the main reason our native pollinators are in decline is a lack of wildflowers in our countrysides and urban areas. To increase the competition for that limited resource puts a huge amount of pressure on the wild pollinators. That means that the populations of those wild pollinators are reduced, you have less abundance and less diversity.”
There are different side-effects to having too many bees. Memmott describes poorly managed honeybees as “little ecosystems of plagues and contagion” due to the excessive density at which they are saved – notably compared with native pollinators, a lot of which are solitary. This threat is far larger when hives of honeybees are saved in shut proximity, as illness spreads extra rapidly between them and out into the wider inhabitants of pollinators.
There is robust proof that a few of the most feared ailments are rising quickly in the areas of highest hive density.
“We had the worst year for European foul brood outbreaks last year,” says Glassborow. “We had more colonies infected – double our previous worst year. It just happens that the hotspots of those infection outbreaks seem to mirror high-density hotspots. That is telling you something is not right.”
Despite all these points, a lot of the UK’s main nature and bug conservation charities are not anti-honeybee. Honeybees present city populations with a possibility to bond with a few of nature’s most charismatic creatures, says Glassborow. “There are lots of pluses about honeybees, particularly in terms of engagement for urban populations. That’s important because more than 50% of the world’s population live in cities. It’s a dangerous situation if they are completely disconnected from the natural world. If the public doesn’t know about it and they have no interest in pollinators, then nothing is going to change.”
The LBKA and different beekeeping associations need to scale back the variety of bees in sure areas, with out lowering the variety of beekeepers. Beekeepers are methods to share hives, in addition to scale back the variety of hives in their apiaries. Efforts are additionally being made to throw their collective weight behind planting programmes resembling Buglife’s B-Line project, which seeks to set up wildflower corridors between pollinator hotspots to permit small native populations to develop and re-establish themselves.
Tim Vivian, a beekeeper in the centre of Birmingham, makes an effort to present as many individuals as attainable his hives, from colleagues to faculties and anyone with a passing curiosity. He says: “I don’t expect everyone I show the hives to take up beekeeping, and I certainly wouldn’t suggest that they did. What is quite possible is everyone who comes to see the hives could do a little bit more to think about habitat and forage for pollinators generally. I say to everyone who comes, if only you would plant a few flowers, plant something that’s good for bees, good for beetles, good for butterflies, we can encourage pollinators to do their own thing and give them enough forage so that they can survive.”
Sarah Wyndham Lewis, additionally of Bermondsey Street Bees, provides: “People want to help; they just need to be given a toolkit. They just need to know more.”
“It’s a question of all things in moderation,” says Memmott, a view shared by Richard Comont from the Bumblebee Conservation Trust. “Beekeeping in and of itself is a good thing for people to be able to do but it’s a question of scale and responsibility,” he says. “There are a lot of wellbeing benefits, and the honey you get out of a hive is massively nicer than anything you can get in the supermarkets. Those sort of reasons are perfectly valid reasons to keep bees.
“As long as you realise that you aren’t doing it to save the bees; in the same way, if you keep chickens next to your beehive you aren’t saving the white-tailed sea eagle.”
