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.
