Households across the UK are being urged to place a bowl of water in their gardens this weekend to help wildlife endure an approaching heatwave, with temperatures expected to reach 30°C in parts of the country.
Why water bowls are essential during the heatwave
The Met Office has forecasted 30°C on Saturday and 29°C on Sunday, with temperatures unlikely to drop below 28°C well into next week in London. These hot, dry conditions with little rain can make life difficult for vital pollinators like bees, as well as birds, hedgehogs, frogs, and other wildlife that rely on fresh drinking water during the summer months.
Bumblebees, which are covered in a furry coat adapted to the UK's usually moderate climate, are particularly vulnerable to overheating. According to the WWF, as hot summers become more intense, bumblebee populations could face increased pressure. The charity warns that bumblebees can easily overheat and become unable to fly or forage, and flowers providing nectar and pollen may wilt and dry out in extreme heat.
Expert advice from WWF
Paul De Ornellas, Chief Adviser for Wildlife at WWF, explained: "Bumblebees are crucial for pollinating crops, fruits and plants, and they always make me smile when I see them. They're vital for maintaining a healthy environment and for our food production. Unfortunately, like many insects, bumblebees are in decline due to habitat loss linked to land use change, pesticides, and pollution, all made worse by climate change."
He added: "As temperatures rise, bumblebees are moving north to look for more suitable environments, but sadly, some species could find themselves with nowhere left to go. Bumblebees also have a furry coat and much prefer cooler climates, as they can easily overheat and become unable to fly or forage. They also struggle in times of extreme heat as the flowers providing them with nectar and pollen may start wilting and drying."
How to provide water safely
De Ornellas advised gardeners to place a shallow tray of water in the garden, with pebbles, branches, or bark above the water level for bees to rest on as they drink. He also recommended planting flowers in shaded areas to provide relief for bumblebees. "If you see a sleepy bumblebee on the pavement or a windowsill in the hot sun, they can be carefully transported to a flower in a shady area if safe to do so," he said.
The Wildlife Trusts emphasise that water is essential for wildlife, not just for drinking but also for shelter and breeding. Amphibians like newts, frogs, and toads use water as shelter and breeding grounds, butterflies obtain valuable minerals and salts from slightly muddy water, and birds use water to bathe and remove parasites. "During hot summer weather, it is important to have plenty of water for animals and birds to drink and bathe in," the organisation stated.
Additional tips for gardeners
Gardeners are also encouraged to soak one food item in water for birds in July, as part of ongoing efforts to support wildlife during the summer heat. By taking simple steps like providing water and shade, households can help local wildlife survive the challenging conditions.
