Wildlife corridors on Costa Rica farms are reshaping how conservationists think about protecting biodiversity, turning working land into a living bridge between two of Central America’s largest protected forests.
Wildlife corridors on Costa Rica farms sound like a contradiction at first. Farms have traditionally been viewed as the opposite of wild habitat, cleared land standing between forest fragments. A growing partnership in southern Costa Rica is proving that assumption wrong.
One farmer, Vivian, illustrates the shift firsthand. Her property sits within a landscape that could reconnect two major protected areas separated by decades of agricultural clearing. After deciding to let the forest regrow, she began planting native fruit trees across her land.
Monkeys and birds soon followed. Vivian noticed more wildlife visiting her farm to feed, a sign she interpreted as scarcity higher up in the surrounding forest. Her farm had quietly become an extension of the habitat it once replaced.
Stories like Vivian’s are central to a new partnership between the nonprofit Rare and Osa Conservation. Osa Conservation has spent years working toward a climate-adaptive mega wildlife corridor spanning southern Costa Rica’s most biodiverse landscape. Rare now joins that effort, contributing behavioral science and community engagement expertise.
That expertise matters because lasting conservation depends on farmers choosing to participate. Land-use decisions ultimately rest with the people who own and work the land, not conservation organizations alone. Understanding what motivates farmers becomes just as important as the ecological science behind corridor design.
Geography explains why this particular stretch of wildlife corridors on Costa Rica farms carries such stakes. The corridor would link the Osa Peninsula, home to Corcovado National Park, with La Amistad International Park in the Talamanca Mountains. Both sites rank among Central America’s most significant conservation areas.
Osa Peninsula alone hosts an estimated 2.5% of the planet’s biodiversity within a remarkably small area. National Geographic once described it as the most biologically intense place on Earth. Roughly half of Costa Rica’s 500,000 known species can be found somewhere within this peninsula’s rainforests and coastal ecosystems.
La Amistad International Park brings its own ecological weight to the partnership. The park contains the largest remaining intact forest in Central America, stretching across the border between Costa Rica and Panama. Its elevation range creates habitat diversity found nowhere else in the region.

Between these two protected giants lies a patchwork of farmland, much of it cleared decades ago for cattle ranching and agriculture. Wildlife corridors on Costa Rica farms aim to stitch that patchwork back together without displacing the people who depend on it economically. Farms remain farms, but portions become forest again.
Climate change adds urgency to this work beyond simple habitat connection. As temperatures shift, many species need to relocate toward cooler elevations or different regions to survive. Corridors give wildlife the pathways they need to move rather than become trapped in shrinking pockets of suitable habitat.
Reforestation on private land also supports genetic diversity among wildlife populations. Isolated forest fragments can trap animal populations, leading to inbreeding and reduced resilience over generations. Reconnecting habitat allows animals to move between areas, mixing gene pools that might otherwise stagnate.
Farmers who participate in these efforts often discover unexpected benefits beyond conservation itself. Native trees can provide fruit, shade, and soil stabilization alongside their ecological value. Some farmers find that biodiversity returning to their land enhances rather than competes with agricultural productivity.
Community buy-in remains the most fragile piece of any corridor project. A single farmer’s decision to reforest carries little weight against a neighboring decision to clear land for expansion. Building a truly continuous corridor requires coordinated participation across dozens or hundreds of individual landowners.
That coordination challenge is exactly where Rare’s involvement could add the most value. Behavioral science offers tools for understanding why some farmers embrace conservation while others hesitate. Applying those insights at scale could determine whether this ambitious corridor project succeeds where similar efforts have stalled elsewhere.
Vivian’s transformed farm offers a small but tangible preview of what success might look like. Wildlife corridors on Costa Rica farms depend on thousands of similar individual choices, each one adding another link to a chain stretching across the region’s most irreplaceable landscape.
