The Hidden Risk Behind Rising Hedgehog Sightings

Hedgehogs in South London. A hopeful sign, but one that still needs our help

We have loved seeing an increase in reports of hedgehog sightings across 2025 so far. For many of us, spotting a hedgehog in the garden or on a quiet street is a joyful moment and a reminder that nature is still finding space alongside us. It is encouraging, but it does not mean the challenge is over.

Hedgehogs remain one of the UK’s most vulnerable native species. Their numbers have declined dramatically over recent decades due to habitat loss, busy roads, and changes in how we manage our gardens and green spaces. Every sighting matters, and so does every small action we take to protect them.

Why this time of year is critical

At this time of year, most hedgehogs should still be hibernating. They may briefly wake during milder spells, but they are generally conserving energy until spring. Hibernation is a delicate process. Waking too often, or too early, can put a hedgehog at serious risk as food is scarce and their energy reserves are limited.

If you see a hedgehog out during the day, this is often a sign that something is not quite right. They may be underweight, injured, or struggling to survive, and they may need help.

How our gardens can help, or harm

Gardens are now one of the most important habitats for hedgehogs, especially in urban areas like South London.

You can help by leaving piles of leaves, logs, or natural debris undisturbed and avoiding tidying too early in the year. These areas provide vital nesting and shelter spots. Please also take extra care before strimming long grass, turning compost heaps, or lighting bonfires. Hedgehogs often shelter in exactly these places, and injuries at this time of year can be fatal.

If you spot a hedgehog out at night that appears alert and is moving normally, it is usually best to leave them alone. This is when hedgehogs are naturally active. You can support them by leaving out a shallow dish of water, especially during dry periods.

However, if a hedgehog is out in daylight, appears injured, cold, or is not moving much, please contact a local wildlife rescue immediately for advice. Acting quickly can save a life.

Small actions. Big impact.

Protecting hedgehogs does not require grand gestures. It is the everyday decisions, leaving a wild corner, checking before gardening, knowing when to call for help, that collectively make a real difference.

Together, we can help ensure that hedgehogs remain part of South London’s wildlife, not just as rare sightings, but as a thriving presence for years to come.
