Warmer Winters Affect Hedgehog Hibernation on Channel Islands
Wildlife experts in the Channel Islands report that rising temperatures are altering hedgehog hibernation patterns and increasing parasite infestations. The Jersey Hedgehog Preservation Group (JHPG) attributes these changes to milder winters, which keep food sources available, reducing the need for hibernation. Traditionally, hedgehogs hibernate between November and March, but now many remain active year-round.
The Alderney Wildlife Trust (AWT) notes that warmer conditions may boost parasites, leaving hedgehogs underweight and foraging throughout winter. Other small mammals, such as bats and rats, are also showing reduced hibernation, possibly due to complex factors like warmer seasons and increased litter sizes.
The Guernsey Society for the Prevention of Cruelty to Animals reports rescuing hedgehogs year-round, as local temperatures rarely drop low enough for hibernation. Conservationists emphasise the need for more research to fully understand how climate change is impacting hibernation and hedgehog health.
