Hibernation series: Hedgehogs
In the final part of our hibernation series, we’re focusing on one of the UK’s most beloved mammals—the hedgehog! Known for their prickly appearance, hedgehogs spend much of their lives asleep, especially during the colder months when they enter hibernation.
Hedgehogs rely on woodland edges and hedgerows for food and shelter. During October and November, they eat as much as possible to build up fat reserves for hibernation, aiming to weigh between 500-700g to ensure their survival. Once they’ve gained enough weight and temperatures drop to around 5°C, hedgehogs begin searching for the perfect hibernation spot in locations such as compost heaps or under garden sheds, creating nests from fallen leaves and twigs. If you’re having a bonfire this winter, be sure to check the pile for a hedgehog home before lighting it.
During hibernation, their heart rate dramatically decreases, dropping from around 190 beats per minute to just 20, helping them conserve energy and survive the winter months. In the spring, they emerge from hibernation, but even then, they are nocturnal, sleeping during the day and becoming active at night.
Hedgehog populations in the UK are sadly declining due to habitat loss. Hedgerows and woodlands, which provide food and protection, are increasingly threatened by modern farming practices and development. The use of pesticides has also reduced insect populations and therefore food sources. Busy roads create a further challenge for our prickly pals. Our team are working hard to create safe and undisturbed habitats for hedgehogs through our conservation efforts at Nature Reserves across East Devon.
To help hedgehogs in your area, leave compost heaps, log piles, or overgrown areas undisturbed. Build a hedgehog house and leave out hedgehog-friendly food and water (but not milk, as hedgehogs are lactose intolerant). By making small changes, we can create a more hedgehog-friendly environment and support their survival through winter.
