Hedgehogs, despite being consistently voted the most beloved mammal in the United Kingdom, have suffered great population losses as industrial agriculture and other human impacts destroy their hedgerow habitats. Our latest guest, Hugh Warwick, has studied, celebrated, written about, and fought to protect hedgehogs for more than 30 years, leading a groundswell of local and individual action to protect the small animal. We spoke with Warwick about his role as the spokesperson for the British Hedgehog Preservation Society, his writings on the impact of manmade lines on the ability of wild animals to thrive, and the environmental importance of loving your hedgehog.
