A study leveraging artificial intelligence and drone technology has revealed a significantly larger seal population along a stretch of the Norfolk coastline than previously recorded through traditional methods. The research, spearheaded by Natural England, utilized high-resolution drone imagery and AI-powered analysis to achieve a more precise population count, marking a substantial advancement in wildlife monitoring.

AI-Powered Drones vs. Traditional Counting Methods
Historically, seal populations have been monitored through on-the-ground observations and aerial surveys conducted by human volunteers. While effective, these methods have inherent limitations, particularly in detecting seals hidden by terrain or clustered in difficult-to-access locations. In this latest study, volunteers manually counted 6,200 seals along an 8-kilometer (4.9-mile) section of shoreline near Winterton-on-Sea. However, AI-assisted drone analysis identified more than 8,500 seals in the same area—an increase of 2,300 individuals.
Gabriella Fasoli, a scientist at Natural England, attributed the discrepancy to the unique vantage point offered by drone technology. "[It] provides a unique viewpoint from above, allowing for a more accurate count by detecting seals that may be hidden or less visible from the ground", she explained.

Enhancing Accuracy and Efficiency Through AI
By processing high-resolution drone images, AI algorithms can swiftly analyze footage, identify seals, and differentiate them from surrounding elements with remarkable accuracy. This method not only reduces human error but also enhances data collection efficiency, eliminating the need for extensive manual counting.
Emma Milner, a senior marine mammal specialist at Natural England, emphasized the benefits of this technological shift. "This cutting-edge technology will help contribute to a comprehensive national picture of seal populations, allowing us to better understand population changes over time", she stated. Additionally, AI-driven analysis enables conservationists to assess the impact of human activity on crucial seal habitats, facilitating improved conservation strategies.

The Future of AI in Conservation Efforts
While the introduction of AI-powered drones marks a significant step forward, Natural England stresses that human volunteers remain essential for data collection and ecological assessments. AI complements rather than replaces traditional methods, providing a cost-effective and scalable solution for wildlife monitoring.
The UK is home to approximately 35% of the global grey seal population, making accurate monitoring a critical aspect of conservation efforts. By integrating AI and drone technology, researchers can now generate more reliable data, improve wildlife protection policies, and mitigate threats to marine ecosystems.

Regulations and Ethical Considerations
Despite the advantages of AI-driven monitoring, ethical considerations and regulatory compliance remain paramount. Special permissions were granted to operate the drones used in this study, ensuring minimal disturbance to the animals. Natural England has also issued a warning that unauthorized drone flights over seal colonies are prohibited, emphasizing the importance of responsible drone use in conservation research.
