40,000 bees have arrived in Canary Wharf
Canary Wharf's working population of 100,000 received a huge hike this week.
40,000 honey bees have set up home on the roof of the offices of professional services firm KPMG.
The colony are in hives at the top of Canada Square office block, as part of a campaign to reverse the decline of the insects in the UK.
Marianne Fallon, UK head of corporate affairs at KPMG, said: "This project is a logical next step using the green roofs which crown many of the buildings across Canary Wharf and is a great way for us to demonstrate our support for biodiversity in our local community."
Once the bees have settled in they are expected to gather pollen from Canary Wharf's green roofs and parks.
The honey will be used in KPMG's staff restaurant Fourteen.
There will also be a beecam so staff at the firm can watch the progress of the colony.
"90% of food worldwide is provided by just 100 crop species," said Marianne. "71 of these are dependent on honey bees, so the serious decline in bees in the UK is a threat to future food supplies. We're keen not only to increase the bee population here in London, but also to encourage our own staff to promote bee-friendly planting in their own gardens."
