Costa Rica’s monkey bridge
In Costa Rica, conservationists have found a clever way to protect the country’s rich wildlife by building bridges high in the forest canopy, allowing monkeys to cross safely. Many species, such as howler monkeys and spider monkeys, live in the treetops and rely on continuous forest cover to move between feeding and nesting areas. However, deforestation and road construction have fragmented their habitats, forcing them to risk dangerous crossings on the ground.
These specially designed “monkey bridges” are made from sturdy ropes or cables strung high above roads, connecting tree canopies on either side. The bridges mimic natural vine pathways, encouraging monkeys to use them instead of descending to the ground. Over time, other wildlife like sloths, squirrels, and birds have also been spotted using these safe corridors.
Local communities, environmental groups, and government agencies work together to install and maintain these structures, often placing them in known animal crossing routes identified by researchers. The initiative has significantly reduced wildlife deaths caused by vehicle collisions and helped preserve the ecological balance in tropical forests.
Costa Rica’s monkey bridges are a simple yet effective reminder that small, thoughtful interventions can make a huge difference in protecting biodiversity.
