National Hedgehog Monitoring Programme aims to understand why population has declined
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.
