Almost half of Britain’s natural biodiversity has disappeared.

Report in the Guardian newspaper:- ” Almost half of Britain’s natural biodiversity has disappeared over the centuries, with farming and urban spread triggered by the industrial and agricultural revolutions being blamed as major factors for this loss.

Britain has lost more of its natural biodiversity than almost anywhere else in western Europe, the most of all the G7 nations and more than many other nations such as China,

The world’s overall biodiversity intactness is estimated at 75%, which is significantly lower than the 90% average considered to be a safe limit for ensuring the planet does not tip into an ecological recession that could result in widespread starvation. On this scale, the UK’s index reading was 53%.”

Why do we need insects?

  1. To pollinate 87% of plants. 75% crops need insect pollination.
  2. Recycle dung, leaves, corpses.
  3. Keep soils healthy.
  4. Control pests, though they can also be pests.
  5. Food for larger animals eg. fish. Crickets are 12 times more efficient than cows in converting vegetation into digestible body mass, produce little or no methane and use 55 times less water.
  6. Insects are in all food chains.

Problems –

German nature reserve studies – over 27 years the insect biomass has dropped by 75%. Forest and grassland had a 40% drop over 10 years.
UK butterflies – over 41 years a 46% drop in common species numbers. 77% drop in rare species numbers.
US studies – 70% drop in insectivorous birds in 20 years.

Widespread continued use of bee-killing neonicotinoid pesticides

“Countries across Europe are exploiting a loophole to allow widespread continued use of bee-killing neonicotinoid pesticides, two years after the EU introduced a landmark ban on their use.

The EU agreed a ban on all outdoor uses of the neonicotinoid insecticides clothianidin, imidacloprid, and thiamethoxam on 27 April 2018, in order to protect bees.

However, an Unearthed investigation has found that in the two years since the ban was agreed, EU countries have issued at least 67 different “emergency authorisations” for outdoor use of these chemicals…”

Monmouth Bee Festival

Monmouth Bee Festival is a family friendly event which takes place at the Nelson Garden in the centre of Monmouth on Sunday 1st Aug 10.00am to 4.00pm.

The Festival includes activities for adults and children, stall holders offering bee derived products, craft stalls, plant sales, key local environmental group displays, and pizza and ice cream!

Monmouth Bee Festival 2021 aims to raise awareness of our work in Uganda which due to recent cuts in the UK government and charity funding for overseas aids is facing a critical moment. We are supporting people with disabilities to access specially adapted training, advice and mentoring so they too can have an equal opportunity to benefit from beekeeping in Uganda

Buglife “B-Lines”

The B-Lines are a series of ‘insect pathways’ running through our countryside and towns, along which we are restoring and creating a series of wildflower-rich habitat stepping stones. They link existing wildlife areas together, creating a network, like a railway, that will weave across the British landscape. This will provide large areas of brand new habitat benefiting bees and butterflies– but also a host of other wildlife.

‘Bee-killing’ pesticide now will not be used on UK sugar beet fields

A Guardian newspaper article:-

“A pesticide which reduces bee populations and was to be used in England’s sugar beet fields this year will not be used after recent cold weather killed off virus-transmitting aphids…..”

Bee Species Down by 25% since 1990

The Guardian newspaper says:-

“The number of wild bee species recorded by an international database of life on Earth has declined by a quarter since 1990, according to a global analysis of bee declines. They found a steep decline in bee species being recorded since 1990, with approximately 25% fewer species reported between 2006 and 2015 than before the 1990s…..”
