Guanacos—fleet-footed cousins of the llama—roam the windswept grasslands of South America in one of the world’s longest overland migrations. But fences, hunting, and competition with livestock are putting their survival at risk. Ahead of the 2nd International Guanaco Day, WCS Argentina is joining forces with local communities and the government to secure vast migration corridors, promote sustainable livelihoods, and bring guanaco populations back from the brink. From live—shearing innovations to landmark land protection, this story reveals how conservation is turning the tide for these resilient creatures—and why their future matters for ecosystems and people alike.  Reporting: Hannah Kaplan Guests: Dr Andrés Novaro, Dr. Susan Lieberman
