Biodiversity Monitoring Using Deep Learning Under Ground Truth Uncertainty: Supporting Conservation of Wandering Albatrosses and Hedgehogs

Technological advances have led ecology into its big data era. Although this offers exciting opportunities for biodiversity monitoring, the volume of data requiring manual processing poses a significant challenge. Popular solutions to this challenge: deep learning and citizen science approaches, have various limitations, but their combination may offer an effective and reliable way forward (e.g. for counting wildlife in aerial survey images Torney et al., 2019 and camera trap data Green et al., 2020). Humans are highly data-efficient compared to deep learning approaches, and there remain fundamental differences between human and machine perception, e.g. in the type of errors made (Geirhos et al., 2021) and sensitivity to data corruption (Geirhos et al., 2018). In this project we will compare the performance and biases of classifications obtained through deep learning and citizen science approaches. In particular, we will focus on the setting where there is uncertainty in the labels assigned by volunteers, i.e. different annotators have provided different labels for the same image (Bowler et al. 2020; Hockerts et al. 2025). Researchers at the British Antarctic Survey (BAS) have prepared a satellite image dataset consisting of citizen science annotations of wandering albatrosses (Diomedea exulans) across 11,839 image tiles from South Georgia Island in the South Atlantic Ocean. This dataset offers an ideal opportunity to study integration of probabilistic AI and citizen science approaches when dealing with uncertainty in detection. We will study if our findings generalize to other settings, specifically to camera-trap data provided through the National Hedgehog Monitoring Programme to study the substantial decline of hedgehog (Erinaceus europaeus) numbers in the UK and corresponding citizen science classifications obtained through the MammalWeb platform. In addition, depending on the students’ interest, fieldwork can be conducted to collect drone data, to be used for further analysis.

Methodology

The research team has expertise on AI for biodiversity monitoring; use of citizen science to inform biodiversity conservation; Bayesian deep learning; transfer learning and robustness of machine learning methods under distribution shifts; sustainable AI; collecting, processing, and analysing different types of data including satellite and camera-trap data; computer vision for detecting and segmenting objects from imagery; and multi-modal representation learning that combines information from different sensors and spatial scales.

Research visits: 1x per year to visit co-supervisors at Durham and BAS.

Placement Year 2: 2.5 weeks at the British Antarctic Survey (BAS) to work with co-supervisor Dr Ellen Bowler, the rest of the AI lab at BAS, and the Wildlife from Space research group.

Collaborator: Dr Peter Stewart (current: Research Associate, University of Glasgow, School of Biodiversity, One Health and Veterinary Medicine, https://peter-stewart.github.io ). Ecologist and conservationist with expertise in camera trap and citizen science approaches.

Collaborator: Dr Paul Eizenhöfer (Senior Lecturer, University of Glasgow, School of Geographical & Earth Sciences, https://www.gla.ac.uk/schools/ges/staff/pauleizenhofer/ ).
Expertise in UAV remote sensing techniques.

Fieldwork: Student will have the opportunity to collect multispectral and photogrammetric drone data under the guidance of Dr Eizenhöfer, which can subsequently be used for analysis under guidance from supervisors and Dr Eizenhöfer.

Project Timeline

Year 1

– Comprehensive literature review.

– Thesis write-up and submission.

Training
& Skills

– The student will receive training and develop skills on computer vision for ecology, probabilistic AI, coding (Python and PyTorch), GitHub, and working with the different types of data considered in this project.
– The student will receive peer-support by being part of a vibrant PGR community at the University of Glasgow, including students from the Leverhulme DTP on Ecological Data Science who are based in the same School (and of which the first supervisor is on the management committee) and who have a regular data science reading group. Further, there will be group meetings with the supervisor’s other students working on related topics from the Leverhulme DTP, NetGain CDT, ExaGEO CDT, and DiveIn CDT.
– The student will receive support in developing communication and public engagement skills from the supervisor team and workshops offered at the University of Glasgow. The student will be encouraged to present in group meetings (including those from collaborating groups), in the PGR seminar, the computer vision and autonomous systems group seminars, and later on at conferences.
– The Graduate School at the University of Glasgow has a Doctoral Training Programme which students are required to participate in to develop transferable skills, including courses on research integrity and data management.
– The student will be part of the annual progress review process in the Graduate School with a review panel consisting of 2 members of academic staff who are not their supervisors.
– The student will be encouraged to attend seminars, conferences, and summer schools, where of relevance to their project. For example, the first supervisor has close collaborators within the Prob_AI (Probabilistic AI) Hub, which offers relevant seminars, summer schools, and conferences, e.g. the Probabilistic AI for Environmental Science conference in 2025. Another example is the Student Conference on Conservation Science in Cambridge https://www.sccs-cam.org
