“When one tugs at a single thing in nature, he finds it attached to the rest of the world.” – John Muir. Just so, the rainforest we are trying to protect is essential for the health of the River Cuero which in turn gives life to the Cuero y Salado Nature Reserve – a beautiful, tangled maze of estuaries and mangroves home to manatees, howler monkeys and a vast array of bird species.
