Hedgehogs are a welcome visitor to gardens as a large part of their diet is made up of invertebrates, with the most important invertebrates for them being worms, beetles, slugs, caterpillars, earwigs and millipedes. They are not only found within our gardens, but are present in most parts of Britain, with he exception of very wet areas and extensive pine forests. however, they are also scarce in upland areas such as moorlands and mountainsides. Hedgehogs thrive in mosaic of hedges, fields and woodlands that characterise the British countryside. These are ideal nest sites, providing a good supply of food, protection from predators and corridors to move along. Hedgehogs are one of the few mammals that are true hibernators. During hibernation hedgehogs are not actually asleep. They drop their body temperature to match their surroundings and enter a state of torpor. This allows them to save a lot of energy but slows down all other bodily functions making normal activity impossible. Hedgehogs usually hibernate from October/November through to March/April. Research has shown that each individual is likely to move nesting sites at least once during this period and so can sometimes be seen out and about. During mild winters hedgehogs can remain active well into November and December. Sadly hedgehog populations in the UK have declined by approximately 50% over the past couple of decades. Although the reason for their dramatic decline is not fully understood, it is known that a number of factors attribute to their decline including: Loss of habitat - including hedgerows, farmland, grasslands and woodland. Habitat fragmentation and loss of commuting corridors - not only due to loss of hedgerows and other habitats, but through the erection of fences round gardens etc, which inhibit the movement of hedgehogs. Use of pesticides in farmland and gardens (including slug pellets) - this not only reduces the volumes of potential prey for hedgehogs to eat, but is also ingested by the hedgehogs when feeding on affected insects. People's Trust for Endangered Species and British Hedgehog Preservation Society together run the Hedgehog Street Campaign. One way you can get involved is by submitting your recordings through their website at: https://bighedgehogmap.org/ There are also many ways that you can support hedgehogs in your garden. Hedgehog friendly garden features including log piles - these provide a safe and secure site for breeding or hibernating hedgehogs, and also insects, providing a yea round food supply for hedgehogs. compost heaps - Compost heaps can create good nesting sites for a hedgehogs (and other wildlife). Open air composting is also great for insects (hedgehog food). leaf piles - Not only can leaf piles be used as a potential nesting site but they can also be used for bedding material for any other nest sites or hedgehog boxes in the surrounding area. wildflower patches - attracts insects ponds - provides a water supply for drinking, as well as attracting food sources for hedgehogs. Although they are excellent swimmers, please make sure there is a gently sloping edge (or stones/logs) to your pond to allow them to escape. hedgehog homes - Although several of the features outlined above can support breeding and hibernating hedgehogs, they will also use specially built hedgehog homes. feeding stations - Feeding stations can be put into gardens to supplement a hedgehogs diet (not to replace it) especially during colder or drier periods, when insects can be much scarcer in gardens. Specially made hedgehog foods both in dry and moist kibble varieties now exist and can be bought from most local pet and garden stores. Hedgehogs will also relish any combination of meat-based wet dog or cat foods as these are high in the protein that they need. Just remember, they will be getting most of their food from insects and worms in the wild, and this food is only supplementary. Hedgehogs are lactose intolerant so please do not give them milk, and as bread is low in energy it is best not to feed this to them. When putting out food, other wildlife may be attracted, so it is worth creating a feeding station to prevent pets and foxes being able to eat this food. It is important if putting out food, that water is also provided.
