Drive around Costa Rica’s windy mountainous roads and you will see numerous trees, from those bearing colorful fruits to others sporting thick spines, planted about 1 to 3 meters apart. Connected by long lines of barbed wire, these rudimentary-looking arrangements, known as living fences, have both economic and environmental benefits over their dead wood counterparts. Farmers across Central America plant living fences because these green barriers are a more economically feasible and readily accessible method for containing livestock and protecting crops. For one, the main materials of living fences are the branches of tree species that root from sticks and grow into larger trees. Shared among neighbors or sold at local markets, these sticks are much cheaper and more common than manufactured posts. Without the need for paint or preservatives, which can add toxins into the environment, maintenance costs also remain low. Additionally, animals graze on living fences, saving farmers costs in livestock feed.
