European hedgehog guide: where to see and how to help hedgehogs

The UK's hedgehog population is in decline, but there are plenty of ways you can help. Here is our expert European hedgehog guide, including where to see them, what they eat and how to help hedgehogs in your garden.

The European hedgehog (usually referred to just as the ‘hedgehog’ in the UK) is one of seventeen hedgehog species found worldwide.

This prickly mammal is a much-loved species, and was even voted as Britain’s favourite mammal by BBC Wildlife readers back in 2013, receiving 42% of the vote and outstripping the badger in second place by almost two votes to one. As BBC Wildlife‘s Ben Hoare said at the time, “You won’t find anyone with a bad word to say about Mrs Tiggy-Winkle.”


What is the scientific name of the European hedgehog?

The scientific name of the European hedgehog is Erinaceaus europaeus.


Where can you see hedgehogs in the UK?

Hedgehogs like dry spaces such as under garden sheds, near compost heaps, hedges or even just an untidy bit of your garden. As a result, it is important be cautious when moving or disturbing such spaces. Take special care during the winter months, as the hedgehog will be hibernating. If you make your garden more hedgehog friendly or build a hedgehog house, then you may be able to see them go for food and drink.

Do hedgehogs hibernate?

During the evenings in the summer months is your best chance of seeing a hedgehog as depending on the temperature, hedgehogs hibernate from November through to March or April.

During hibernation, a hedgehog’s body temperature can fall to less than 10°C, its heart slows to fewer than 20 beats a minute and it virtually stops breathing.  Hedgehogs build winter nests, called a hibernaculum, under leaves or structures such as sheds or, unfortunately bonfires which is why it is essential to check before lighting.

What is hibernation?

Hibernation is a way for many creatures – from butterflies to bats – to survive cold, dark winters without having to forage for food or migrate to somewhere warmer. Instead, they turn down their metabolisms to save energy.

Are hedgehogs endangered in the UK?

It’s thought that hedgehog numbers declined by up to a half in rural areas and a third in urban areas between 2000 and 2015. The availability of habitat and food may be two of the main factors affecting them, along with them being killed on roads. The use of pesticides reduces the numbers of invertebrates that they feed on.

In 2020, the first official Red List for Britain’s Mammals was produced by the Mammal Society for Natural England, Natural Resources Wales, Scottish Natural Heritage, and the Joint Nature Conservation Committee, and authorised by the IUCN on a regional level. 11 species were deemed to be at risk of extinction, including the hedgehog (listed as Vulnerable alongside the hazel dormouse), Scottish wildcat (listed as Critically Endangered), Eurasian beaver, red squirrel and water vole (all listed as Endangered).

Badgers and foxes can both attack hedgehogs, but we don’t know how common it is or how often a hedgehog is killed. It’s also complex because all three species eat invertebrates and are therefore competing for the same food sources.

We have found you’re less likely to find hedgehogs where badgers and foxes are present, but simple correlation does not imply causation. In short, it’s not clear how predators contribute to the long-term hedgehog decline.

How to spot hedgehog signs

What do hedgehog tracks look like?

Faint trails through flowerbeds or long grass or across dew-covered lawns in the early morning may indicate that a foraging hedgehog has been in the area.

Hedgehog footprints show their five toes, with claw marks, measuring roughly 2.5cm in length and 2.8cm in width. Their prints are hard to find, so try leaving out a ‘footprint tunnel’ that has an ink pad to record them.

What do hedgehogs sound like?

If you hear huffing, snuffling or wheezing in your garden at night, it’s a fair bet that you have hedgehogs. They are noisiest on warm evenings in May–July, the peak breeding season in Britain.

Hedgehog scats are dark, gritty and up to 5cm long. Often they glisten with indigestible prey fragments, such as beetle wingcases, though these are absent if a hedgehog has been eating mostly worms.

How to help hedgehogs in your garden

Hedgehog expert Hugh Warwick shares these easy steps to help hedgehogs in your garden:

1

Create a wild corner in your garden

Add a tussocky patch to your garden as a perfect daytime nesting area for hedgehogs. Allow a corner of your lawn to grow long, or sow a mix of native grasses and wildflowers, such as meadow foxtail, cock’s-foot, lesser knapweed, yarrow and ox-eye daisy.

Leave this vegetation over winter as it provides a crucial habitat for many invertebrates to complete their life-cycle – a garden buzzing with insects is a great garden for hedgehogs.

2

Plant a tree

If space allows, plant an oak, beech, hornbeam or lime tree. These have the ideal leaf size for hedgehogs to make their winter hibernation nests.

If you buy trees from a nursery, check they haven’t been imported from Europe and have been grown from British seed in the UK.

3

Turn allotments and veg beds into havens

Growing veggies creates perfect ‘hogitat’, so long as you avoid chemicals and don’t fence your plot with netting or chicken wire (try living willow instead). Speak out at allotment management meetings: hedgehogs make great pest controllers.

Avoid chemicals

Go chemical-free. Using weedkiller on your lawn reduces the availability of earthworms, a key hedgehog prey item. Slug pellets and pesticides can also make hedgehogs very ill or even kill them.

5

Provide nesting places

Go natural! Purpose-built ‘hog houses’ are fun and sometimes used, but a woodpile is a multi-functional, one-stop shop for hedgehogs, providing abundant insect food together with a sheltered spot for them to start a family. Simply leaning a piece of wood against a wall or fence can help, too.

6

Make a compost heap

Composting is better than wasting money on fertilisers and a huge help to hedgehogs. This is because leaf decay, and the associated bacteria and fungi, support diverse communities of creepy-crawlies, which in turn are food for hedgehogs.

Start your mound of decaying plant matter in a spot that’s accessible to hedgehogs and open to the elements: avoid covered heaps or bins.

7

Break down barriers

Opening up your garden is the bread and butter of being hedgehog-friendly. So if you do nothing else, cut 13cm by 13cm holes in your fences at ground level, or make small tunnels underneath the panels. These will be too small for pets, but big enough for grateful rotund hogs to pass through.

8

Offer extra food and water

Supplement natural foods by offering specific hedgehog food, or meat-based cat or dog food, or cat biscuits.

This is most important if you spot any active hedgehogs in November–March, the usual hibernation period, when invertebrate prey is scarce. Remember to also provide fresh water if possible, especially during dry weather or if leaving out dry food.

Rescue hedgehogs

Sick, injured, orphaned or underweight hedgehogs can be saved by expert care, and many are released back into the wild.

If you find an animal you’re worried about, put it in a box indoors with a towel to hide under and contact your local hedgehog hospital, or call the British Hedgehog Preservation Society on 01584 890801.

How to protect hedgehogs on Bonfire Night

The British Hedgehog Preservation Society (BHPS) is asking everyone to take care this Bonfire Night and to prevent horrific and unnecessary suffering to hedgehogs and other wildlife.

Bonfire piles, made up of dry wood and leaves, look like the perfect hibernation spot for hedgehogs, so BHPS have come up with a four-point plan for people to follow:

  1. Bonfires should not be built until the day they are to be lit.  This will not only save wildlife from burning to death but will also stop the bonfire from getting soaked should it rain the night before!
  2. If a large bonfire must be built in advance, protect it whilst building by putting some chicken wire one metre high all the way around the bottom.  This should be held in place with stakes and the wire should slope outwards at an angle to make it difficult to climb, as hedgehogs are good climbers!  A ring of old tyres around the base stacked a few high can also work.
  3. If, whilst building, a bonfire is left unattended for however short a time, it’s imperative to check for hedgehogs and other animals including family pets, or even young children, before lighting. Hedgehogs tend to hide in the centre and base of the bonfire, check the bottom metre or so by gently lifting the bonfire section by section with a pole or broom. Never use a spade or fork as these can cause terrible injuries.  Using a torch will help and listen for a hissing sound, as this is the noise they make when disturbed.
  4. When lighting, do so from only one side so there is an escape route for anything you may have missed.

“If material is stored on open ground in advance of having a bonfire, it’s crucial to dismantle it and move it to another spot just before lighting,” says Fay Voss, chief executive of BHPS.

“Ensure it’s moved to clear ground – never on top of a pile of leaves as there could be a hedgehog underneath, and not too close to pampas grass which can ignite very easily and is another favourite spot for hedgehogs to hide under.”

If you find a hedgehog, the BHPS recommend:

  1. If hedgehogs are found, take as much of the nest as you can and place them in a high-sided cardboard or plastic box with plenty of newspaper/old towelling. Make sure to wear gloves to keep human smells to a minimum and to protect your hands.
  2. Ensure there are air holes in the lid and the lid is secured firmly to the box, as hedgehogs are great climbers.
  3. Put the box in a safe quiet place such as a shed or garage well away from the festivities, offer specialist hedgehog food, meaty cat or dog food and water.
  4. Once the bonfire is totally dampened down, release the hedgehog in the same area under a hedge, bush or behind a stack of logs.

If you find an injured hedgehog, the BHPS recommends following steps 1, 2 and 3 above, then calling them on 01584 890 801 for further advice and the numbers of local contacts.
