Can AI detect hedgehogs from space? Maybe if you find brambles first.

You can't spot a hedgehog from space, but you might be able to find where they live by looking for brambles. That's the premise behind ongoing research at the University of Cambridge, where scientists are using satellite imagery and AI models to map potential hedgehog habitats across the UK by first identifying their favorite hiding spots: bramble patches. European hedgehog populations have declined by roughly 30 to 50 percent over the past decade, so tracking these nocturnal creatures across large areas remains difficult and expensive. Rather than searching for the hedgehogs directly, researcher Gabriel Mahler developed an AI model that identifies brambles, which are thorny shrubs that hedgehogs use for shelter and foraging, from satellite data. These small mammals rely on this type of dense vegetation for daytime shelter, nesting sites, and protection from predators. Brambles also attract insects and provide berries, supporting the invertebrate populations that hedgehogs eat.Read full article Comments
