One of the things I've learned over my many years working to save cotton-top tamarins is that conservation is never something you accomplish alone. It takes scientists, educators, farmers, local communities, and dedicated conservationists working together toward a common goal. And sometimes, some of the most valuable lessons come from people who are working to protect an entirely different species in another part of the world. That's why I was particularly excited when members of Proyecto Washu, a conservation organization in Ecuador dedicated to protecting the critically endangered brown-headed spider monkey (Ateles fusciceps), came to Colombia to visit Proyecto Tití.
Although our organizations work in different countries and very different forests, we have much in common. Proyecto Tití works to protect cotton-top tamarins in Colombia's tropical dry forests, while Proyecto Washu focuses on protecting brown-headed spider monkeys and their habitat in Ecuador. Both species face the challenges of habitat loss and fragmentation, and both organizations recognize that saving endangered primates requires much more than protecting the animals themselves. We must also protect and restore their forests while working closely with the communities that share their habitat.
Sharing What We've Learned
During their visit, Proyecto Washu field assistants Galo Álava and Diego Macías had the opportunity to learn about our forest restoration efforts, including our tree nurseries, seed bank, germination techniques, and strategies for restoring degraded habitat. These are activities we've been developing and refining over many years, and it was rewarding to see how interested our visitors were in understanding not just what we do, but why we do it.
Galo was particularly interested in our germination beds and seed bank. Growing a forest may sound as simple as collecting seeds and planting trees, but anyone who has worked in restoration knows there's much more to it! We need to understand which seeds germinate successfully, how to care for young seedlings, and where trees should be planted to give them the best chance of survival. By carefully managing these early stages, we can make better decisions about restoring forests that will eventually provide food, shelter, and safe passage for wildlife. Diego was interested in how we evaluate an area before beginning restoration. At Proyecto Tití, we don't simply plant trees wherever there's an open space. We consider the landscape, topography, existing vegetation, and opportunities to reconnect fragmented forests. Our goal isn't just to grow trees—it's to restore functioning ecosystems that support cotton-top tamarins and the many other species that depend on these forests.
But the learning wasn't one-sided. Proyecto Washu shared its approach to monitoring individual trees using unique identification codes, allowing its team to track the growth and survival of each plant. It's a great example of how even organizations with years of experience can learn something new by looking at how others approach similar challenges.
Different Forests Require Different Solutions
One of the most interesting aspects of our discussions was comparing the environments where we work. Colombia's tropical dry forests experience long periods with little rainfall, making water availability a major challenge for newly planted trees.
At Proyecto Tití, we've developed techniques to help seedlings survive these difficult conditions, including the use of water-retaining materials. Proyecto Washu works in the much wetter forests of Ecuador, where restoration presents different challenges. A technique that works well in Colombia may not be necessary—or even appropriate—in Ecuador. That's an important lesson in conservation: there is no single solution that works everywhere. The key is understanding the ecosystem, learning from others, and adapting successful approaches to local conditions. These conversations reminded me that conservation is as much about asking good questions as it is about finding answers. Why does one planting strategy work better than another? How can we improve seedling survival? What information should we collect before deciding where to restore a forest? By sharing our experiences, we can help one another avoid mistakes and develop more effective conservation strategies.
Conservation Is About People, Too
Of course, restoring forests is only one part of the story. Both Proyecto Tití and Proyecto Washu understand that long-term conservation success depends on the people who live alongside endangered wildlife. We can plant thousands of trees, but if local communities don't see the value of protecting those forests, our efforts are unlikely to succeed.
During the visit, we shared how Proyecto Tití works with farmers and landowners to protect existing forests, establish wildlife corridors, and restore degraded areas. Rather than simply asking people to set aside land for conservation, we work to understand their needs and develop agreements that benefit both people and wildlife. This approach particularly resonated with our visitors, who recognized opportunities to adapt similar strategies in Ecuador. We also discussed the importance of environmental education, especially working with children who can become powerful advocates for conservation within their families and communities.
Two Primates That Need Our Help
Although cotton-top tamarins and brown-headed spider monkeys look very different, they share something important: their futures depend on healthy, connected forests. Brown-headed spider monkeys are among the world's most threatened primates. They depend heavily on fruit and need large areas of forest to find enough food. They are also extraordinary seed dispersers, helping forests regenerate as they travel through the canopy. Unfortunately, habitat loss, fragmentation, and hunting have placed their survival at serious risk. Cotton-top tamarins face many of the same challenges in Colombia. Both species remind us that protecting a primate means protecting an entire ecosystem. When we restore a forest corridor for cotton-top tamarins or brown-headed spider monkeys, we're also creating habitat for birds, reptiles, insects, and countless other species that share those forests.
Learning Together, Growing Together
Perhaps my favorite part of this visit was hearing how much our colleagues appreciated the opportunity to exchange ideas with our team. They weren't simply looking for techniques to copy. They wanted to understand what we've learned, which approaches have worked, and how those experiences might be adapted to their own conservation challenges.
I was especially pleased that the conversations didn't end when the visit was over. Our team exchanged contact information with our visitors so they could continue asking questions and sharing experiences. To me, that's what makes these exchanges so valuable. They aren't just visits to another conservation project; they're opportunities to build relationships that can continue long after everyone returns home. After decades of working to protect cotton-top tamarins, I know that conservation is a constant learning process. We've celebrated successes, faced setbacks, and changed our approaches as we've gained new knowledge. And we still have plenty to learn! Organizations like Proyecto Washu remind us that innovative ideas can come from anywhere, and that sharing our experiences makes all of us better conservationists.
I'm grateful to Galo, Diego, and the Proyecto Washu team for taking the time to visit us, ask thoughtful questions, and share their own experiences. I hope they'll return to Ecuador with some useful ideas for protecting brown-headed spider monkeys, just as we've gained new perspectives from their work. Because whether we're protecting cotton-top tamarins in Colombia or brown-headed spider monkeys in Ecuador, we're working toward the same goal: a future where endangered primates, healthy forests, and local communities can thrive together. And the more we learn from one another, the better our chances of making that future a reality.
