AI in Action: Detecting Brambles to Support Ecosystem Monitoring
In an innovative field test, researchers demonstrated the capabilities of an AI model designed for ecological monitoring, particularly in identifying brambles. Jaffer, a member of the research team, documented the experience in a blog post, noting, “It took us about 20 seconds to find the first one in an area indicated by the model.” Starting their exploration at the Milton Community Centre, where the AI model predicted a high likelihood of bramble presence near the car park, the team systematically visited various locations based on the model’s confidence levels.

Promising Results from Early Tests
The research team found that at Milton Country Park, every high-confidence area surveyed contained substantial bramble growth. Interestingly, an investigation of a residential hotspot revealed an empty plot that was overrun with brambles. In a rather amusing twist, a prediction in North Cambridge led the team to the aptly named Bramblefields Local Nature Reserve, where extensive bramble coverage was confirmed.
The AI model showed particular strength in detecting large, open bramble patches easily visible from above. However, smaller brambles that were shielded by tree cover yielded lower confidence scores. Jaffer provided insight into this limitation: “Since TESSERA is learned representation from remote sensing data, it would make sense that bramble partially obscured from above might be harder to spot.”
A Step Forward in AI Ecology
While these initial findings are promising, it’s important to note that the bramble detection project is still a proof-of-concept currently under active research. The team has yet to publish the model in a peer-reviewed journal, and the informal field validation highlights the need for more systematic studies.
Despite these limitations, the project showcases an exciting application of neural network techniques in diverse domains beyond conventional uses in generative AI models like ChatGPT. Should the research continue to yield results, its simplicity may provide significant advantages. Unlike more resource-intensive deep learning models, this system could potentially run on mobile devices, facilitating real-time field validation.
The research team is also contemplating the development of a phone-based active learning system, enabling field researchers to refine the model while simultaneously verifying its predictions.
Future Implications for Ecological Monitoring
As research progresses, similar AI-based methodologies combining satellite remote sensing and citizen science data could revolutionize the way we monitor invasive species, track agricultural pests, and assess changing ecosystems. For endangered species like hedgehogs, rapidly mapping critical habitat features is increasingly vital in a world where climate change and urban development continuously alter their environments.
