  "account": "A new study conducted by Nottingham Trent University reveals that road deaths can decimate hedgehog populations, with the risk being especially high for smaller groups. Researchers examined four populations of varying sizes in Nottinghamshire and discovered that collisions killed between 15% and 29% of each group annually. Larger populations, while experiencing more traffic-related deaths, managed to maintain stability due to higher reproductive rates and the fact that the majority of fatalities were male. However, for smaller groups with fewer than 15 individuals, even a few deaths could have a devastating impact, potentially leading to extinction. Hedgehog populations in Britain have been declining for years due to habitat loss, food scarcity, predation, poisoning, and injury from farming and gardening equipment. Currently, rural populations are estimated to have dropped by 30% to 75% since 2000, while urban populations have stabilized and may be recovering. The study, funded by the British Hedgehog Preservation Society and People's Trust for Endangered Species, aimed to determine the extent of road deaths' effect on these vulnerable groups. Lead researcher Dr. Lauren Moore emphasized that while larger populations may suffer more from roadkill, smaller populations are particularly at risk. The research calls for better support for hedgehog populations, including bolstering smaller groups, creating habitat to support more animals, and providing safe passage to allow them to move and increase their viability without crossing roads. Simple actions such as leaving wild areas in gardens and creating \"hedgehog highways\" can help mitigate the impact of road deaths on these declining species.",
