Conservationists Secure Seeds of Rare Cacti in Chile's Atacama Desert

Conservationists from Chester Zoo have completed a significant mission to protect rare plant life in Chile's Atacama Desert. The team worked in one of the driest environments on Earth to collect seeds from highly threatened cactus species. These plants face severe risks from climate change, urban development, and illegal poaching. By securing these seeds, experts hope to ensure the survival of species that are currently on the brink of disappearing from the wild. Paul Bamford, the regional field programme senior manager for Latin America at Chester Zoo, led the effort alongside Richard Hewitt, the zoo's plant nursery team manager. The project involved a partnership with the Cactus Lagarto Nursery and the INIA Intihuasi Seedbank. These local organizations provided essential support and will now house the collected seeds for long-term preservation. This collaboration highlights the importance of international cooperation in modern conservation work. The team traveled more than 2,000 kilometers across the desert to reach the remote habitats of these unique plants. They successfully gathered seeds from five critically endangered species, eight endangered species, five vulnerable species, and two species classified as least concern. Many of these cacti had never been included in a seed bank before this expedition. The process required careful, manual work, with the team using tweezers to remove seeds from wild Copiapoa plants. Copiapoa cacti are particularly vulnerable because they grow very slowly and often exist only in small, isolated areas. Their seeds do not travel far from the parent plant, which limits their ability to spread naturally. This restricted range makes them highly susceptible to environmental damage and human interference. Because of these factors, the successful collection of these seeds is considered a vital step in preventing their total loss. Chester Zoo has maintained a national collection of Copiapoa for over two decades, providing a foundation of expertise for this project. The zoo also uses its on-site Plant Project area to educate the public about the various threats facing cacti worldwide. Richard Hewitt noted that the team's next objective is to work with Chilean experts to establish best practice guidelines for future seed-saving efforts. These guidelines will help standardize how conservationists protect similar plant species in other arid regions. This initiative is part of a broader global trend of focusing on plant biodiversity as a key component of ecological health. While many conservation efforts prioritize large animals, experts emphasize that protecting native flora is essential for maintaining stable ecosystems. The seeds stored at the INIA Intihuasi Seedbank will serve as a genetic safety net for the future. This project demonstrates how targeted, science-based interventions can provide a buffer against the ongoing impacts of climate change.
