City gardens have become havens for bees driven off farm land by pesticides and lack of flowers

Why BEES prefer middle class gardens: Insects forced out of their natural habitats seek out lavender, dandelions, brambles and buttercups to pollinate

  • Changes to farmland are causing bees to seek refuge in green city spaces
  • Allotments and urban gardens identified as the best environment for bees
  • Garden owners are encouraged to mow their grass less and plant more flowers 

Bees driven off farm land due to changes in their natural environments are finding refuge in the ‘posh’ urban gardens of the middle classes.

Private green areas inside towns and cities, as well as communal spaces like allotments and parks, have become safe spaces for the pollinating insects.

That’s down to the diversity of attractive species on offer, including lavender, dandelions, brambles and buttercups, researchers say.

Bees’ natural habitats are being threatened by the use of pesticides and man-made changes to the range of plant species found in the environment.

In the future, cities could become important for all insects, which face threats such as pest control on agricultural land, an international team of researchers found.

Results from their four-year study found allotments and urban gardens are the best environment for bees.  

Gardens in richer areas typically had a wider range of flowers, the team found. 

This is consistent with the so-called ‘luxury effect’ whereby higher socioeconomic status is often positively linked with urban biodiversity. 

‘In our case, the effect is driven by the greater quality of floral resources for pollinators in wealthier neighbourhoods,’ the authors wrote in the study.

It identified urban allotments and household gardens as the best spaces for pollinating insects and suggests that these spaces are made more available to allow insects to thrive. 

The type city gardens that attract pollinating insects the most include those with lavender, borage, dandelions, thistles, brambles and buttercups, species that gardeners can keep in mind when planting green spaces.

Owners of garden spaces have been encouraged to mow their lawns less than usual to attract bees.

The study also recommended that public greenspaces should be managed so they benefit pollinators. 

Parks, road verges and other greenspaces make up around a third of cities but have fewer pollinator visits and resources for pollinators than other land uses.  

Gardens make up a quarter to a third of the area of UK cities and better garden management in new developments and existing gardens is likely to benefit pollinator conservation.

City planners and local councils should increase the number of allotments and other community gardens in towns and cities, experts say.

Allotments are good for pollinators as well as people and increasing their area even by a small amount could have a large positive effect on pollinators.

Professor Graham Stone, of the University of Edinburgh’s school of biological Sciences, said: ‘Pollinating insects are vital to supporting plant life, and urban spaces can play a key role in providing environments.’

‘Gardens can account for up to one-third of the area of towns and cities. The more flowers we plant at home, the better it is for bees, butterflies and other insects.’ 

The full findings were published in the journal Nature Ecology and Evolution today. 

WHAT IS THE HONEYBEE CRISIS?

Honeybees, both domestic and wild, are responsible for around 80 per cent of worldwide pollination, according to Greenpeace.

But bee colony collapses across the globe are threatening their vital work.

Bees are dying from a combination of pesticides, habitat destruction, drought, nutrition deficit, global warming and air pollution among other factors.

The global bee crisis can potentially be solved if dangerous pesticides are eliminated, wild habitats are preserved and ecological agriculture is restored, according to Greenpeace (file photo)

Greenpeace has reported: ‘The bottom line is that we know humans are largely responsible for the two most prominent causes: Pesticides and habitat loss.’

This is important for a number of reasons, chief among them the amount of work bees put into our food production.

Vegetables, nuts and fruits are pollinated by bees. Of the top human food crops, a whopping 70 of 100 are pollinated by the creatures, which account for as much as 90 per cent of global nutrition.

Greenpeace has suggested the following solutions to the problem:

  • The preservation of wild habitats in order to protect pollinator health
  • The restoration of ecological agriculture
  • The elimination of the world’s most dangerous pesticides
