A new global conservation plan is focusing on saving the Copiapoa cacti, some of the rarest and most threatened plants in the world. Found only in Chile’s Atacama Desert—the driest place on Earth—these cacti are facing numerous dangers, from climate change to illegal collection, putting their survival at risk.

Why Copiapoa Cacti Matter

Copiapoa cacti may seem tough, but they are vital for the desert ecosystem. They survive with minimal water, relying on coastal fog for moisture. Beyond just being a unique plant, Copiapoa provides shelter and food for wildlife, helps prevent soil erosion, and plays a role in the carbon cycle—making them essential for desert resilience.

Unfortunately, more than two-thirds of Copiapoa species are critically endangered. Their limited range and slow reproduction rate make it harder for them to adapt to changing climates. With their habitats drying up, many species could disappear forever.

Protecting Copiapoa Cacti from Growing Threats

The new conservation plan, developed by the International Union for Conservation of Nature (IUCN) and partners like Chester Zoo, aims to protect these cacti and their fragile habitats. Key actions include increasing legal protections for their environment, expanding protected areas, and raising awareness to stop illegal collection for trade.

Climate change is a significant threat, but illegal harvesting and habitat destruction from development also put pressure on these cacti. By working together, scientists, conservationists, and local communities hope to safeguard Copiapoa populations for future generations.
