The scorching summer of 2026 has left wildlife charities across the South of England reeling, as they grapple with the unprecedented impact of record-breaking heatwaves on the natural world. As the Met Office predicts this summer to be the hottest on record, the consequences for wildlife are becoming increasingly dire, with a wide range of species struggling to cope with the extreme conditions. Anne Brummer, manager of Harper Asprey Wildlife Rescue, paints a grim picture of the situation, highlighting the knock-on effects of the heat on ecosystems. She notes that the early fruiting of trees, which should provide winter food for birds, could disrupt the natural balance of the food chain. Moreover, the impact on migratory birds, which rely on these food sources, could be catastrophic.
One of the most concerning issues is the dehydration of wildlife, with Brummer reporting a surge in cases far higher than ever before. She explains that staying hydrated in the heat is challenging for both humans and animals, and the consequences of dehydration can be severe. Luke Waclawek, founder of Oxfordshire Wildlife Rescue, agrees, emphasizing that all wildlife, from the tiniest mice to larger animals like deer, is affected by the heat. However, he points out that hedgehogs seem to be particularly vulnerable, with many coming in extremely dehydrated.
The problem is not just the direct impact of the heat, but also the resulting ground conditions. Waclawek explains that the rock-hard ground has depleted the hedgehogs' vital food source, insects, which are now deep underground and out of reach. This has led to a significant increase in the number of dehydrated and orphaned hedgehogs being cared for by the RSPCA, with figures indicating a 30% rise over the same period in 2025.
However, there are things people can do to help mitigate the impact of the heat on wildlife. Waclawek suggests letting a square metre of your garden grow wild, as this can attract a surprising variety of wildlife. He also recommends putting out a small bowl of water with pebbles for insects, as they are essential for the ecosystem. Brummer agrees, emphasizing that the pebbles help to slow down the evaporation of the water, creating a haven for insects and birds, and especially hedgehogs.
In my opinion, the impact of the heatwaves on wildlife is a stark reminder of the interconnectedness of our natural world. The knock-on effects on ecosystems and food chains are a cause for concern, and it is crucial that we take action to help mitigate the impact. While it may seem like small steps, letting a patch of your garden grow wild and putting out a bowl of water with pebbles can make a real difference. It is up to all of us to do our part in protecting our precious wildlife, and to ensure that future generations can continue to enjoy the natural world.
What makes this particularly fascinating is the way in which the heatwaves are disrupting the natural balance of ecosystems, and the knock-on effects on migratory birds and food chains. It is a stark reminder of the fragility of our natural world, and the importance of taking action to protect it. From my perspective, it is crucial that we continue to raise awareness of the impact of climate change on wildlife, and that we work together to find solutions to this pressing issue.
