Catalan Genome Project researchers are creating a comprehensive genetic archive of the region’s unique wildlife.
This ambitious scientific initiative, known as the Catalan Biogenome Project (CBP), aims to sequence the complete genetic code of hundreds of species native to Catalan-speaking territories.

The project represents a modern ‘Noah’s Ark’ for biodiversity, designed to aid conservation, medical research, and our understanding of evolution in a changing climate.
Catalan Genome Project Unlocks Secrets Of Endangered Species
A key early success involved the Iberolacerta aurelioi, a Pyrenean mountain lizard found only in a tiny, high-altitude habitat. Researchers from the Institute of Evolutionary Biology (IBE) successfully obtained its first complete genome after locating a single male specimen in Andorra. “Having its genome allows us to understand how it has evolved and adapted to its environment,” explained project leader Salvador Carranza. Consequently, this genetic blueprint provides crucial data for assessing population health and establishing protective measures.
The project’s scope is vast, targeting around 200 representative species. These range from Mediterranean corals and endemic plants to reptiles, birds, and subterranean fauna. Furthermore, the initiative connects to the global Earth Biogenome Project, positioning Catalan research on the international stage. Researchers argue the work is urgent, as the Mediterranean region is a global biodiversity hotspot containing about 25% of Europe’s species.
Medical and conservation benefits are significant drivers. For instance, scientists are sequencing the genomes of all 13 snake species in the region, including venomous vipers. “Knowing the genes associated with toxins opens the door to developing new drugs and antidotes,” noted predoctoral researcher Sergi Tulloch. Similarly, the first genome produced was for the Balearic shearwater, Europe’s most endangered seabird, providing data to guide its conservation.
A Living Library For Future Generations
All genetic data is deposited in international repositories for global scientific access. Importantly, the project ensures a copy of each scientific publication is available in Catalan. “When we send the article to the journal, a Catalan copy is saved in the repositories,” said botanist Teresa Garnatje with pride. This effort preserves traditional knowledge alongside genetic data.
Plant genomes present a particular challenge due to their complex, repetitive DNA structures. However, the team persists with species like the popular Arnica montana, which is threatened by overharvesting. “Having its genome is crucial to help raise awareness and establish conservation policies,” Garnatje emphasised. Samples are also preserved in the unique Barcelona CryoZoo, a collaborative project creating a frozen library of cell lines from threatened animals.
Ultimately, this genetic atlas is more than a catalogue. According to Marta Riutort, co-president of the initiative, it helps conserve organisms and, by extension, their entire environment. “We must all be aware that our health depends on our environment,” she stated. “Everything is interconnected.” The project’s progress, amid growing calls for environmental action, highlights science’s role in safeguarding our natural heritage for the future.
