A recent conversation with someone revealed that apparently there have only been about 5 sightings of hedgehogs recorded in my area recently. Now I haven't recorded any and neither have several friends but we've all seen them around our streets at night. The gap between what's recorded and what's actually out these is clearly a problem.
In the last 50 years the hedgehog population in the UK fell from 30 million to an estimated 1.5 million. That's a big drop! Now the British Hedgehog Preservation Society and People's Trust for Endangered Species are calling for a new climate survey of these prickly mammals to find out if their hibernation is being affected by climate change.
