In the warm and humid forests of the Colombian Magdalena Medio, one of the most biodiverse regions in the country, the brown spider monkeys survive despite being in critical danger of extinction.
Their presence is not a result of chance, but of the commitment of scientists, local communities, and rural producers who, for the past two decades, have been working to restore ecological corridors, protect habitat, and reconcile conservation with livestock production.
Two decades of science, conservation, and community bond
The project began as a study of the ecology and behavior of brown spider monkeys, led by biologists Gabriela de Luna and Andrés Link. Over time, the research gave way to a strategy of participatory conservation, involving ranchers, farmers, and local residents.
“Studying their behavior led us to understand that conservation is only possible if it is built with those who inhabit the territory,” explains Link in dialogue with CNN.
An extraordinary species revealing connections with humans
The brown spider monkeys are one of the largest primates in South America, weighing up to 10 kg, with a powerful prehensile tail and unique body markings that allow for identification.
But what fascinates researchers the most is their complex social behavior: they live in stable groups, greet each other, hug, and show dynamics similar to those of chimpanzees, our closest relatives.
Ecological restoration: corridors connecting life
The Primates Project Foundation promotes the creation of biological corridors that allow monkeys, jaguars, tapirs, and birds to move freely between forest fragments. The process includes:
- Selection of native seeds
- Cultivation in community nurseries
- Planting in strategic areas to connect habitats
So far, between 15 and 20 corridors have been developed, covering about 30 to 35 hectares each, but interconnecting over 1,000 hectares.
Empirical science with local roots
Locally generated knowledge is key. “The nurseries are managed by local people, who test, adjust, and improve restoration strategies,” explains Link.
Furthermore, camera traps have been installed in trees and on the ground to monitor fauna and assess the impact of the corridors. These tools have also strengthened the bond with landowners, showing them the natural wealth their lands harbor.
Sustainable livestock: a possible alliance
In the absence of large national parks, conservation depends on landowners. One of them, Juan Andrés Jaramillo, has been collaborating with biologists for over a decade in tree planting, camera installation, and the development of more efficient and resilient livestock farming.
“We have to give back part of what we have damaged. There is no excuse not to restore,” he states firmly to the mentioned portal.
Environmental education and local pride
Since 2011, community festivals have been held to celebrate biodiversity, with costumes, games, and educational activities. This approach has generated local pride and awareness of the value of native species.
“Many know about the Siberian tiger, but not about the jaguar or the brown spider monkey that lives near their home. We want to change that,” says De Luna, who was recognized by National Geographic with the Wayfinder Award, and by the Whitley Fund for Nature for her leadership in conservation.
Although the brown spider monkeys remain threatened, progress is tangible. “This is not just work, it is a life project,” says De Luna. “Every day we decide what kind of world we want to leave behind. I want a better one for my daughters, for people, for my daughters’ children.”
