There's now more than just anecdotal evidence that England's hedgehog population is feeling the squeeze. In the past 55 years,there has been a moderate decline of up to 7.4 percent in the areas they frequent, says Anouschka Hof of the University of Wisconsin-Madison in the US and Paul Bright, and previously of the University of London in the UK.

Their findings are published in Springer's European Journal of Wildlife Research.
