The crisis facing bees and other pollinators in the UK has caused the government to launch an “urgent” review of the country’s environmental wellness, and pledge to introduce a national pollinator strategy. Lord Rupert de Mauley, minister at the Department for Environment, Food and Rural Affairs (Defra), noted, ‘As we all recognise, pollinators play a vital role in the security of our food supply and the quality of our natural environment. In safeguarding their future, we can secure our own.’


In April, UK ministers opposed the European Union’s suspension of the use of three neonicotinoid pesticides linked to serious harm bees, albeit with the plan going ahead anyway. Friends of the Earth’s executive director Andy Atkins commented, ‘We’re delighted that enormous pressure for a bee action plan from scientists, businesses and the public has stung the government into action. The minister’s plan of action must be in place when bees emerge from hibernation next spring: we can’t afford to gamble any longer with our food, countryside and economy.’


According to Lynne Dicks, an expert on wild pollinators at the University of Cambridge, ‘All pollinators, not just bees but also many flies, butterflies, moths, wasps and beetles, rely on flowers, but the number of flowers in the countryside declined calamitously in the 20th century: we lost 97% of our flower-rich meadows between 1930 and 1984…Through enhancing the yield of many high value crops, pollination is worth between £430m and £510m to the UK economy, but amazingly, pollination doesn’t seem to be considered as an important agricultural input.’ She added, ‘At the moment, it is almost impossible for us to know whether actions to help bees and flies are having an effect, because we have no long-term monitoring.’


As it stands, we have lost nearly all of the UK’s wild honey bees, and some species of bumblebee have been lost altogether. De Mauley said, ‘We know there are gaps in the evidence. That is why I am launching an urgent and comprehensive review of current policy, evidence and civil society action on pollinators to identify what needs to be done to integrate and step up our approach. This urgent review will form the basis of a national pollinator strategy, which will bring together all the pollinator-friendly initiatives already underway and provide an umbrella for new action.’

Almost a third of American honeybee colonies did not make it through the winter. This is according to the country’s beekeepers, who say that the high death rate could mean a huge hit to environmental wellness. The annual survey was started by the US Department of Agriculture six years ago, and, on average, 30% of all the honeybee colonies died off over each winter.


The worst year was five years ago, but last year was the best – with just 22% of the colonies dying. Jeffrey Pettis, research leader of the Agriculture Department’s Bee Research Laboratory in Beltsville, Maryland, commented, ‘Last year gave us some hope.’ However, this year has dashed that hope, seeing a bee colony death rate off 31%.  Pettis explained that beekeepers are mostly seeing colonies that just dwindle, and as the crowd of bees gets smaller, it gets weaker. Pettis noted, ‘They can’t generate heat very well in the spring to rear brood. They can’t generate heat to fly.’


Not only is this a problem for the bees and their keepers, but also farmers who rely on commercial beekeepers to make sure their crops get pollinated. It is getting to the point where there may not be enough honeybees to pollinate crops, such as almonds, blueberries and apples. Pettis said that farmers have now come closer than ever to a true pollination crisis, with the only saving grace this year for part of the almond crop in California being the good weather at pollination time. ‘We got incredibly good flight weather,’ Pettis explained. ‘So even those small colonies that can’t fly very well in cool weather, they were able to fly because of good weather.’


Beekeeping will soon no longer be a viable business, Pettis said, as beekeepers can afford to lose only about 15% of their colonies each year. However, he added, some commercial beekeepers will just keep on going because they love the business so much. ‘It’s just something that gets in your blood, so you don’t want to give up. [You say,] “OK, it’s 30 percent this year; I’ll do better next year.” We’re very much optimists,’ he enthused.
