Satellites and AI Used to Track UK Hedgehogs in Bid to Slow Decline

Research teams at the University of Cambridge are utilizing cutting-edge satellite technology and artificial intelligence to address the alarming decline of hedgehogs in the UK. Human activities have led to a staggering decrease in hedgehog populations, with estimates indicating a fall of up to 75% in rural areas since 2000.

The AI tool, named Tessera, enables researchers to analyze detailed satellite images of the UK. This tool allows them to map hedgehog habitats with precision, revealing significant details like individual hedgerows and identifying potential barriers that hedgehogs face in their search for food and mates. Insights from this mapping can inform conservation strategies, particularly in relation to the impact of housing developments and other environmental changes.

Additionally, the project is melding satellite imagery with real-time data collected from hedgehogs fitted with tiny GPS trackers—affectionately dubbed "digi-hogs." This innovative approach allows for real-time tracking of hedgehog movements, helping researchers understand urban versus rural dynamics where hedgehogs are retreating primarily to urban areas as their numbers dwindle.

Professor Silviu Petrovan, a strategy and research manager at the People's Trust for Endangered Species, expressed optimism about leveraging AI for further hedgehog protection. He noted the importance of identifying barriers to food and mate access in broader conservation efforts.

However, the project is not without criticism. Some environmentalists highlight concerns regarding the energy-intensive nature of AI technology, advocating for a cautious approach. The Tessera initiative aims to reconcile technology and conservation needs, providing a valuable tool not just for hedgehogs but also for monitoring biodiversity at a larger scale.

With more than 100 research groups having accessed the Tessera system, its applications extend beyond hedgehogs to other areas such as agricultural monitoring, offering a comprehensive view of changes in landscapes over time and fostering data-driven strategies for conservation. The continuous advancements in AI and environmental science mark a hopeful chapter in the ongoing struggle to protect vulnerable species like the hedgehog.
