A University of Oxford mapping project has mapped hedgehog sightings in London by distorting the borough size by the number sighted. Unsurprisingly, the fewest were spotted in the city, with the most seen in the borough of Richmond-upon Thames. It would be interesting to see this for the whole of the UK. The highest numbers in England are reported to be in the North East, Yorkshire and East Anglia.

Hedgehog sightings are just one topic that the project has mapped. Others include unemployment, air pollution and house prices. I'm glad hedgehog numbers are considered to be as important as these topics. You can see the full list of maps here: http://www.londonmapper.org.uk/
