Reconnecting the Treetops: How Project Reconecta is Saving Brazil’s Arboreal Wildlife
When humans build roads through dense wilderness, the asphalt creates an invisible, deadly wall. While ground-dwelling animals face cars directly on the pavement, arboreal species—creatures that live entirely in the upper canopy—face a different kind of trap. For animals like monkeys and sloths, a cleared highway is an impassable canyon. If they refuse to descend, their populations become fragmented, cutting off gene flow and threatening their long-term survival.
Enter Project Reconecta, an innovative initiative transforming how modern infrastructure coexists with nature by stringing heavy-duty, multi-layered rope networks high above highways. At the helm of this movement is a brilliant mind in road ecology and engineering design: Fernanda Abra.
Engineering Solutions: The Vision of Fernanda Abra
As a pioneering Brazilian wildlife biologist and founder of the consulting firm ViaFAUNA, Fernanda Abra grew tired of simply documenting the tragic toll of vehicle collisions on wildlife. Turning scientific research into hands-on enterprise, she committed herself to building practical, scalable solutions.
Abra designed Reconecta’s aerial crossings to function like customized tightrope highways. Constructed from durable, interwoven ropes, the structures are meticulously tailored to accommodate different animal locomotor styles—whether an animal walks upright, swings underneath by its arms, or anchors itself using a prehensile tail. Her work proves that smart engineering can successfully stitch a severed forest canopy back together without halting human transit.
Global Non-Profit Power: Backing Biodiversity from New York
Scaling up grassroots conservation requires serious institutional muscle. Key projects and expansions under the umbrella of these canopy initiatives have been actively supported and funded through major global conservation entities, including international partnerships alongside organizations like the Wildlife Conservation Society (WCS).
Operating out of New York with an asset scale exceeding $1.25 billion, WCS directs substantial resources toward protecting wild places and critical species corridors across more than 50 countries. By channeling major funding, technical expertise, and foundation backing (such as grants from the Segré Foundation) into Brazil's infrastructure zones, these large-scale non-profit partnerships help transform localized pilot ideas into standardized, government-backed environmental policy.
The Data: Trail Cameras Capture Astonishing Success
To measure whether animals would actually trust and adopt these high-altitude bridges, researchers turned to trail cameras mounted strategically on the anchor poles. The results captured by these motion-activated lenses have been extraordinary.
Monitoring data from pilot implementations—such as those in Alta Floresta, Mato Grosso—recorded thousands of safe crossings with zero roadkill incidents on the protected spans. The cameras revealed a fascinating behavioral timeline: while clever and cautious animals like tufted capuchins took up to several months to overcome their initial hesitation, they eventually embraced the routes as part of their daily territory.
Protecting Rare and Newly Discovered Species
The true triumph of these rope networks is the protection they afford to vulnerable and endemic wildlife. Camera traps have documented a wide array of local species utilizing the spans, including:
Black spider monkeys
Red howler monkeys
Opossums and sloths
The endangered Schneider’s marmoset
The Alta Floresta titi protein (Plecturocebus grovesi), a remarkable species that was only scientifically discovered and described in 2019.
By keeping these populations connected, the bridges ensure that newly discovered and heavily threatened primates can travel safely, feed, and maintain genetic diversity. Thanks to the hard data gathered by trail cameras and spearheaded by visionary engineering, Brazil’s federal transport department has officially designated these canopy bridge layouts as a recommended national standard—proving that brilliant engineering and dedicated enterprise can successfully bridge the gap between human progress and the natural world.
