Google Launches AI Project for Rainforest Conservation
Google Arts & Culture and DeepMind launch Forest Listeners, a crowdsourced AI project for rainforest conservation, engaging the public in species identification.
Google Launches Forest Listeners: Crowdsourced AI for Rainforest Conservation
Google Arts & Culture and Google DeepMind have launched Forest Listeners, a groundbreaking online experiment that invites the global public to participate in rainforest conservation by listening to and identifying animal calls from Brazil’s Atlantic and Amazon rainforests. The project, announced in November 2025, leverages the power of crowdsourced AI to help scientists monitor biodiversity and assess the health of these vital ecosystems.
Users access the experiment through a 3D virtual forest interface, where they search for hidden species by their unique calls. By clicking “yes” or “no” when they hear a specific animal sound, participants contribute valuable training data for Perch, Google DeepMind’s AI model designed to automatically recognize species from audio recordings. This initiative marks a significant step in democratizing environmental science, allowing anyone with internet access to become a citizen scientist.
How Forest Listeners Works
Forest Listeners is built on a dataset of over 1.2 million audio recordings collected from remote locations in Brazil’s rainforests. These recordings capture the sounds of countless species, many of which are difficult to observe visually. The challenge for scientists has always been the sheer volume of data—manually analyzing thousands of hours of audio is impractical, especially given the urgent need to monitor rapidly changing ecosystems.
The experiment immerses users in a virtual 3D forest environment, where they can choose to explore either the Atlantic or Amazon rainforest. Each session presents a series of audio clips, and users are asked to identify whether a specific animal call is present. Their responses are aggregated and used to train Perch, improving its ability to detect and classify species in future recordings.
Collaboration and Scientific Impact
Forest Listeners is a collaborative effort involving WildMon, WeForest, Ipê, George Mason University, the National Institute of Amazonian Research (INPA), and the Biological Dynamics of Forest Fragments Project (BDFFP). These organizations provide the audio recordings and scientific expertise necessary to ensure the project’s accuracy and relevance.
Marconi Campos, Chief Scientist at WildMon, emphasized the importance of this initiative: “We’re able to gauge the health of a forest from the inside out by listening to the diversity and patterns of animal behavior. But analyzing the thousands of hours of audio recordings is a challenge, and training data for audio models is lacking for many important species all over the world, including the Brazilian rainforests.”
The Role of AI in Conservation
The use of AI in conservation is not new, but Forest Listeners represents a significant advancement by combining machine learning with crowdsourced human input. Traditional AI models require large amounts of labeled data to learn, and this project addresses that need by engaging the public in the labeling process. The resulting dataset will be one of the largest and most diverse collections of rainforest sounds ever assembled, providing a valuable resource for scientists and conservationists.
Perch, the AI model at the heart of Forest Listeners, is designed to be open-source, allowing researchers around the world to use it in their own conservation efforts. By automating the process of species identification, Perch can help scientists monitor biodiversity more efficiently, track the success of restoration projects, and identify areas at risk.
Broader Implications and Future Directions
Forest Listeners is part of a growing trend toward citizen science and public engagement in environmental research. By making conservation accessible to a global audience, Google hopes to inspire greater awareness and action on behalf of the world’s rainforests. The project also highlights the potential of AI to address some of the most pressing challenges in environmental science, from monitoring biodiversity to assessing ecosystem health.
As rainforest ecosystems face unprecedented threats from deforestation, climate change, and habitat loss, initiatives like Forest Listeners offer a new way to harness the power of technology and collective action for conservation. By turning our collective ears to the rainforest, we can help protect what might otherwise go unheard.
