A scientist helped protect thousands of hectares of former cattle pasture in Costa Rica and let the forest recover; today it forms part of a 130,000-hectare World Heritage rainforest.

Tropical ecologist Daniel Janzen pioneered a radical forest restoration approach in Costa Rica. He protected land and stopped fires, allowing forests to return naturally. This experiment transformed cattle pastures into a thriving, biodiverse ecosystem over time. The Guanacaste Conservation Area now links diverse habitats and supports wildlife movement. This project demonstrates the power of natural regeneration and long-term protection for damaged landscapes.
