In the last decade, hedgehog numbers have gone down in the British Isles by 30% due to a variety of factors, including habitat loss and changes in farming techniques, and the population is endangered from a variety of sources.
Many worms, beetles, slugs, caterpillars and millipedes — which form the hedgehog’s natural diet — have been killed off by chemical treatments and intensive farming methods.
Badgers also compete for the same food.
A recent wildlife survey by the Royal Society for the Protection of Birds found that the number of people who have never seen a hedgehog in their garden rose to 24% last year.
And as hedgerows and the countryside, which forms their natural habitat, dwindles, so the garden becomes even more important as a hedgehog haven. So what can we do to save this prickly garden favourite?
They need plenty of access to search for food, nesting sites and mates.
Cut a 13cm-squared hole in your fence or dig a channel under garden boundaries to allow them to wander and get your neighbours to do the same.
Log and leaf piles, wilderness areas and purpose-built hedgehog homes are ideal places for hedgehogs to nest and hibernate.
Fallen leaves make the perfect nesting material, so don’t clear all of these away in autumn. Pile them in quiet, undisturbed corners of your garden to allow hedgehogs a safe, secure area to breed and hibernate.
Hedgehogs hoover up more than 100 invertebrates such as snails, slugs and worms every night, so no need to use slug pellets.
Hedgehogs have poor eyesight, but are quite curious, meaning they fall into holes and get stuck, so cover up any open drains and gullies.
If you have a pond, make sure you provide an access point so hedgehogs can climb back out. Create a slope with stones or other material.
Attract plenty of natural hedgehog food by keeping your garden diverse with a wide variety of habitats.
Mulching beds with garden compost will encourage earthworms, woodlice and beetles as it begins to rot down, while woodpiles encourage a rich feast of earwigs, centipedes and woodlice. Let your grass grow a little wild and leave some leaf litter.
Both are important homes for the hedgehog’s prey including ground beetles and leatherjackets.
Every year, hedgehogs die under bonfire piles that have not been checked before being lit. Always build your bonfire on clear ground (not on top of leaf litter) and check for hedgehogs before lighting.
Cut a clear hole in a plastic storage box and weigh down the lid with bricks to stop cats and foxes taking the food. If you are worried about attracting rats, don’t put out grain-based foods on the floor and take in any excess food when your hedgehog has visited.
