Artificial intelligence will be used for the first time to track hedgehog populations as part of a pioneering project aimed at understanding how many of them are left in the UK and why they have suffered a decline.

Images of the prickly mammals snuffling around urban parks, private gardens, woodlands and farmland will be captured by cameras and filtered by AI trained to differentiate between wildlife and humans.

The images will then be sent to human “spotters” who will pick out those featuring hedgehogs and send them to analysts, who will record the numbers and locations.

Using this method, the National Hedgehog Monitoring Programme (NHMP) hopes to be able to produce estimates of hedgehog populations in different habitats across the country, show how these are changing year on year, and – in time – give a national estimate of the UK’s hedgehog population.
