🐝 The Decline of Solitary Bees
When most people think of bees, they picture honeybees buzzing in hives. But in truth, over 90% of bee species in the UK are solitary bees — and many of them are in trouble.
Solitary bees don’t live in colonies or produce honey. Instead, each female creates her own nest, often in small tunnels, cracks in wood, or hollow stems. They’re gentle, hard-working, and crucial to pollination — yet they’re often overlooked in conservation efforts.
📉 What’s Happening?
Solitary bee numbers have been falling fast. In the UK:
- A third of wild pollinators have declined since 1980
- Seventeen species have already vanished from parts of the country
- Almost a quarter of Europe’s bumblebee species face extinction
Many solitary bees have extremely local populations — so when their habitat is lost, they simply can’t relocate.
🚨 Why Are They Declining?
Solitary bees rely on a mix of nesting sites and flowering plants to survive. But modern landscapes are working against them.
- Loss of natural habitats — wildflower meadows, hedgerows, and decaying woodlands are disappearing fast
- Fragmented green spaces — bees need connected areas to forage, not isolated lawns or flowerbeds
- Chemical pesticides — even “bee-friendly” sprays can harm solitary bees' immune systems and behaviour
- Climate change — unpredictable seasons are causing bees to emerge before food is available
🌼 Why It Matters & How Borough Bee Helps
🌼 Why It Matters
Solitary bees are powerful pollinators. Species like red mason bees and leafcutter bees are far more efficient per bee than honeybees — making them vital for fruit, vegetables, and wildflowers.
Without them:
- Crops like apples, strawberries, and tomatoes suffer
- Biodiversity falls
- Our ecosystems weaken from the bottom up
💡 How Borough Bees Helps
Our Bernie Bee Trail is built around the idea that conservation should be simple, fun, educational, and community-led.
Each bee hotel gives solitary bees a place to nest. Each sign teaches visitors — especially children — why these bees matter. You can even provide free wildflower seed packets for visitors to take and plant at home which brings the conservation outside the ark and across the community.
By supporting solitary bees, you’re helping protect not just pollinators, but the wider health of our parks, gardens, and food systems.
