The bumblebee makes an astonishing recovery

For those of us worrying about the future of our planet following the extinction of the bumble bee, this article in today's Independent comes as a blessed relief.

It is too early of course to celebrate but the sudden revival of the species is certainly good news. The paper says that a project that began as an attempt to reintroduce an extinct bumblebee to Britain has sparked a comeback by five other species whose numbers have dwindled alarmingly in recent decades.

Conservationists now believe that the speed of their recovery suggests that the bees can cope with some pesticide use by farmers, if they have wild flowers to feed on and a place to live:

Pesticides have been blamed for killing off many bumblebees, which are vital as they pollinate fruit and vegetables – a free service worth some £560m a year to the UK economy.

Seven of the 25 bumblebee species are considered threatened enough to be in the UK Biodiversity Action Plan. Five of these, the brown-banded carder, moss carder, red-shanked carder, large garden and shrill carder, have been found in increasing numbers at the reintroduction project in Kent.

Short-haired bumblebee queens – brought to the UK from Sweden – nested this autumn for the first time in this country for 25 years.

Conservationists began the project in 2009 by encouraging wild flowers to grow on a 20-hectare plot near Dungeness in Kent. They have now expanded this prime bumblebee habitat across more than 800 hectares in Kent and Sussex. The UK has lost over 97 per cent of its wild flower meadows due to agricultural intensification and urbanisation.

The programme has attracted attention in France, where officials believe the researchers may have found a way to halt bumblebee decline across Europe. Cédric Vanappelghem, a conservation officer in northern France, said its “results are good”, and added that they were planning to study bumblebees there shortly.

Given that none of us really have the time to go around pollinating flowers ourselves, the survival of the bumble bee is absolutely crucial. I am pleased that we are making progress towards that goal.
rather be stung by a bee than swipe at one (unlike Wasps)
