Researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have unveiled an innovative dataset named MammAlps, which represents a significant leap forward in the study of wildlife behavior. Captured over multiple views and modalities in the stunning Swiss Alps, MammAlps offers an extensive digital resource that records the intricate interactions of wild mammals in their natural habitat. This pioneering effort could greatly enhance wildlife monitoring and conservation strategies, helping ecologists gain deeper insights into animal behaviors that are difficult to observe in real-time.
The necessity for understanding the unfiltered behaviors of wild animals is rapidly becoming more imperative, especially in the context of ongoing climate changes and the encroachment of human activities on natural habitats. Behavioral insights are critical for grasping the dynamics of ecosystems, and thereby protecting these fragile environments. However, documenting these behaviors authentically—without disturbing the animals—is a formidable challenge that researchers have grappled with for years.
Historically, methods such as direct observation or attaching sensors to wildlife have proven to be either too invasive or limited in their comprehensive scope. While camera traps have offered a less intrusive avenue for documentation, they present their own complications, primarily due to the overwhelming amounts of footage that require analysis. Processing this data can be a labor-intensive task that demands substantial time and resources, often outpacing the ability of researchers to glean meaningful insights.

The use of artificial intelligence (AI) has shown promise in the analysis of large video datasets, but its efficacy largely depends on the quality of the annotated data fed into it. Current video datasets often suffer from limitations—either scraped from the internet and lacking the authenticity of wildlife environments or consisting of small-scale, isolated recordings lacking critical contextual details. Furthermore, few datasets encompass the rich contextual information—such as multiple camera angles and corresponding audio—necessary for comprehending the complexity of animal behavior in ecological settings.
MammAlps represents a solution to these challenges, created through a collaborative effort between EPFL scientists and the Swiss National Park. This dataset is the first of its kind to offer richly annotated, multi-view, and multimodal insights into wildlife behavior. Designed with the intent to train AI models for recognizing species and their behaviors, MammAlps aims to foster a more thorough understanding of how animals navigate their environments. By leveraging this dataset, future conservation efforts could not only become more efficient but also more cost-effective, ultimately leading to smarter strategies for safeguarding wildlife.
The process of developing MammAlps was meticulous and detail-oriented. Researchers established nine camera traps strategically placed in the Swiss Alps, which recorded over 43 hours of raw footage. This extensive collection was then rigorously processed; AI tools were utilized to detect and track individual animals, distilling the raw footage to approximately 8.5 hours of significant material capturing a variety of wildlife interactions. These interactions were not only pivotal for understanding individual behaviors but also for recognizing patterns over time, manifesting how animals relate to their habitats and one another.
Behavioral annotations were developed using a hierarchical framework, meticulously categorizing each recorded moment into two distinct levels: high-level activities such as foraging or playing, and more granular actions like walking, grooming, or sniffing. This layered labeling methodology allows AI models to draw connections between individual movements and larger behavioral patterns, enhancing the accuracy of behavioral interpretation. Such a detailed structure is indispensable for training AI algorithms, which can now learn with greater precision from complex datasets rich in contextual information.
In a bid to further enrich the dataset, the research team supplemented the video data with audio recordings and “reference scene maps.” These maps documented essential environmental factors like the locations of water sources, vegetation, and geological structures, allowing AI to grasp habitat-specific behaviors more effectively. The endeavor was not merely restricted to visual and auditory data; a comprehensive cross-referencing of weather conditions and counts of individual animals at various incidents was implemented, generating complete scene descriptions that can significantly aid in future analysis.
Professor Alexander Mathis of EPFL highlights the advantages of this multi-modal approach, stating that integrating various types of data leads to a more nuanced understanding of animal behavior. With the ability to utilize video in conjunction with audio and reference materials, researchers can develop a comprehensive narrative around wildlife actions, rather than relying on fragmented representations from single modalities.
The innovative aspects of MammAlps extend beyond mere data collection; it sets a new benchmark for wildlife monitoring. This dataset elevates the standard by offering a holistic sensory snapshot of animal behavior that spans multiple contexts, angles, and environmental influences. The introduction of a “long-term event understanding” benchmark allows researchers not only to explore isolated behaviors captured in transient clips but to study extended ecological interactions over time. This capability is especially crucial for observing complex behaviors such as a predator’s pursuit of prey across varying camera perspectives.
As the research continues, the team remains committed to further expanding MammAlps through ongoing data collection efforts. Plans for 2024 include more exhaustive fieldwork, aimed at identifying rare species like the alpine hare and the lynx, as well as refining techniques for analyzing wildlife behavior across seasonal variations. The expansion of the dataset and its corresponding methodologies will provide invaluable tools for researchers seeking to understand the changing dynamics of ecosystems amidst ongoing climate and environmental shifts.
Ultimately, the potential impact of developing datasets like MammAlps is vast, offering the opportunity to radically enhance current wildlife monitoring practices. By employing AI models capable of identifying critical behaviors from exhaustive hours of footage, conservationists will gain access to timely, actionable insights. This information will be essential for tracking the implications of climate change, human encroachment, and disease outbreaks on wildlife behavior, providing crucial information that could aid in the preservation of vulnerable species for generations to come.
Having been recognized for its contributions to the field, MammAlps has been selected as a Highlight to be featured at the IEEE/CVF Computer Vision and Pattern Recognition Conference (CVPR), slated for June 2025. The attention garnered by this dataset not only emphasizes its significance but also highlights the urgent need for innovative approaches in the study of wildlife behavior and conservation.
For those interested in further information about MammAlps or accessing the dataset, the project team has made it available online, providing open access to this pioneering work. The implications of this endeavor reach far beyond academia, promising to shape the future of wildlife conservation and research in meaningful ways.
