Shoulder-to-Shoulder: Clearing the way for tomorrow’s forest, 14 & 18 June 2026

Shoulder-to-Shoulder: Young hands preparing tomorrow’s forest

This June, Las Casas de la Selva had the pleasure of welcoming not one but two remarkable groups through the Shoulder-to-Shoulder (SStS) program. One group was made up of students from Thayer Academy, Braintree, Massachusetts, and their staff, Sarah, Matt, and Leanna, and the second brought together high school students from across the United States, with staff Cassandra, Jim, and Ben. Though they came from different schools, backgrounds, and communities, they shared something important: a willingness to work hard, learn deeply, and contribute to something larger than themselves.

Their task was not glamorous; they took on a most important and physically demanding job in rainforest restoration—clearing hillsides of fern and razor grass in preparation for future tree planting.

Anyone who has worked in a tropical mountain forest knows that preparing a site for planting is often harder than the planting itself. Steep slopes, dense vegetation, and the relentless growth of tropical plants like razor grass require determination and teamwork. Yet these students embraced the challenge. Armed with loppers, hand tools, gloves, and a great deal of enthusiasm, they cleared pathways and planting areas that will soon become home to new trees.

The work was led by Jon Warwick, who guided the crews with patience, good humor, and an eye for both safety and purpose. Under his leadership, the students learned that restoration is not simply about planting trees. It is about understanding landscapes, working as a team, and recognizing that meaningful environmental stewardship often begins with tasks that demand persistence and care.

Every branch cut and every patch of hillside cleared represented an act of preparation for something that may take decades to fully reveal itself. Forest restoration is an exercise in optimism. The people who prepare the ground may never sit beneath the full canopy of the trees they make possible. Yet they work anyway; their efforts are an investment in the future.

At Las Casas de la Selva, we often say that forests are built by many hands over many years. The rainforest surrounding us today bears the marks of countless volunteers, researchers, students, and staff who have contributed their labor since the project began more than four decades ago. Trails, nurseries, drainage systems, restoration sites, and young forests all exist because people chose to invest their time and energy in a place they may only know briefly.

The students of Shoulder-to-Shoulder became part of that continuing story.

Their visit also reflected the larger mission of Shoulder-to-Shoulder itself. Founded in 2007 in response to a simple but profound question—“What can we do?”—the organization was created to provide students with opportunities to explore real-world challenges and discover meaningful ways to engage with them. What began with one school, thirty students, and three nonprofit partners has grown into a global network that now spans four continents, twelve program sites, and numerous partner schools and organizations.

At the heart of Shoulder-to-Shoulder is a belief that the world’s challenges require ethical leadership. The organization seeks to inspire and support generations of leaders who understand that progress cannot be measured solely by economic growth, but must also account for social responsibility and environmental stewardship. Ethical leadership asks people to work collaboratively, think critically, and act with an awareness of how their decisions affect communities and ecosystems.

These values were visible throughout the students’ time at Las Casas.

Rainforest restoration is, by its very nature, an ethical act. It requires people to consider timescales beyond their own lives and to make choices that benefit future generations. It asks participants to appreciate the intricate relationships between forests, watersheds, biodiversity, and human well-being. Most importantly, it reminds us that meaningful environmental work is rarely accomplished alone.

Shoulder-to-Shoulder’s model recognizes this reality. By bringing together schools, nonprofits, businesses, and philanthropists, the organization creates opportunities for collaboration across sectors that might not otherwise meet. It demonstrates that complex global problems require partnerships and shared responsibility.

For many of the students, this experience was also a lesson in the value of physical work. Clearing vegetation on steep rainforest slopes under tropical conditions demands endurance and resilience. The labor encourages teamwork and reveals something that is increasingly difficult to experience in modern life: the satisfaction of accomplishing something tangible with one’s own hands.

At the end of each day, tired but smiling students returned from the hillsides knowing they had made a real contribution. The cleared areas awaiting planting are visible evidence of their efforts, but perhaps the greater result is less tangible. Experiences like these often plant seeds of another kind.

A student who has spent a day clearing a hillside for future forest restoration may never again think of trees as abstract environmental symbols. Forests become places that require care, patience, and human commitment. Conservation becomes something one participates in rather than merely discusses.

And, of course, no day of hard work in the rainforest would have been complete without good food. While Jon led the crews in the field, 3t made sure everyone returned to delicious home-cooked lunches, and a talk after lunch about the project. Sharing meals together is another important part of the experience—a time to rest, laugh, reflect on the day’s work, and build friendships across schools and communities. Sometimes moments around a table often become some of the most enduring memories of service experiences. They remind us that community is built not only through shared labor but also through shared meals, conversations, and moments of appreciation.

As we look at the cleared hillsides and anticipate the upcoming tree planting, we are grateful to both Shoulder-to-Shoulder groups for their energy, curiosity, and willingness to contribute. The trees that will one day grow there will stand as living reminders that restoration begins with preparation and that meaningful change often starts with people who are willing to ask a simple question:

What can we do?

This year, the answer was clear. They came to a rainforest in Puerto Rico, picked up tools, worked together on steep hillsides, shared meals, and helped prepare the ground for a forest that future generations will inherit. That is ethical leadership in action.

Thanks to Bill Cotter, Director of International Programs SStS, for bringing these teams to us.

Branson School: A Day of Work in the Forest, 7th April, 2026

For a single day, 15 students (15-17 years), and staff from The Branson School, Marin County, CA, stepped into the working landscape of Las Casas de la Selva. It was a day of real service work.

They joined us on the forest road, where maintenance is constant and essential. Under the guidance of Jon Warwick, who led the crew with clarity and pace, the students got straight into it. Branches were cut back, ferns were cleared from the road edges, and bamboo was pruned where it had begun to close in. The goal was simple: keep the road open, safe, and functional in a place where growth never stops.

The work demanded attention and effort. Tools in hand, the group moved steadily along the road, learning quickly that in the rainforest, maintenance is not a one-time task. It is ongoing, physical, and necessary for everything else we do here to function.

What stood out was their willingness to engage. No hesitation. No standing back. They worked as a team, taking direction and finding rhythm in the process. This is where learning shifts. Not abstract, but grounded in action.

Back at base, 3t prepared a delicious lunch. Simple, direct, and well earned. Food really tastes different after a morning of physical work, it brings people together in a different way. Conversations and questions over lunch delved into the history of the project. Thanks to group leader, Adelina, and school staff, Sabrina and Matt. Writer, Gregg Dugan and visual artist Mercury, who are both on extended art residencies at Las Casas de la Selva, provided behind-the-scenes help with all and everything.

The visit reflects something important about Branson’s stated values: courage, kindness, honor, and purpose. These are not just ideas to talk about. They show up in how students step into unfamiliar environments, take on physical challenges, and contribute to something beyond themselves. At Las Casas, this kind of exchange matters. Students arrive for a short time, but the work they do stays. A cleared road section, a maintained path, a space that continues to function because of their effort.

About the Program

This visit was made possible through Shoulder-to-Shoulder, a program founded in 2007 to respond to a simple but urgent question: What can we do? Under the direction of Bill Cotter (director of programming), the organization connects students with real-world projects across multiple continents. What began with one school and a small group of students has grown into a global network spanning 12 sites, built on partnerships between schools, nonprofits, businesses, and philanthropists. Their focus is clear: developing ethical leaders who can navigate a complex world while balancing growth, social responsibility, and environmental stewardship. Programs like this one at Las Casas are where that intention meets action. One day. Real impact.

A Day of Service on the Ethnobotanical Trail

We were grateful to welcome a group from Rocky Mountain School to Las Casas de la Selva for a focused day of service work on our ethnobotanical trail. Days like this sit at the heart of what Las Casas represents: learning by doing, caring for place through direct action, and understanding forest systems from the ground up. The crew worked under the guidance of Jon Warwick, who led pruning and trail maintenance along sections of the ethnobotanical trail that see regular use by researchers, students, and visitors. Careful pruning is not just about access; it is about encouraging healthy plant structure, protecting sensitive understory species, and keeping the trail legible without overwhelming the forest’s own rhythms.

Students approached the work with focus and good humor, quickly finding their stride with hand tools and learning how each cut has consequences over time. Trail work in a rainforest is always dynamic. Growth is constant, and maintenance becomes an ongoing dialogue with the landscape rather than a one-time task.

By the end of the day, areas of the trail were clearer, safer, and better defined, but more importantly, the forest had been met with attentive care. These moments of shared labor leave a quiet imprint. They build relationships between people, between people and place, and between learning and responsibility. 3t provided a delicious lunch!

We thank Rocky Mountain School and staff Brittany Bergin-Foss and Sierra Aldrich, for bringing their energy and curiosity into the forest and for contributing to the ongoing stewardship of Las Casas de la Selva. Many thanks to Fernando of Carite 3.0 and to Bill Cotter of Shoulder 2 Shoulder for bringing the group to us.

Shoulder to Shoulder, June 2025

This June, we had the pleasure of meeting two incredible groups of teenagers through the inspiring organization Shoulder to Shoulder—a nonprofit based in Colorado that brings students into global service learning experiences. With 14 students in each group, these visits brought a vibrant mix of energy, curiosity, and heartfelt engagement to the rainforest at Las Casas de la Selva.

On June 12th, the first group arrived, eager to dive into learning about sustainable forestry, conservation, and life in a tropical rainforest. These young people from all over the US—many of them visiting Puerto Rico for the first time—spent the day exploring the land, asking deep questions about our work, and reflecting on how our mission resonates with their own values and sense of purpose.

Then, on June 15th, a second group joined us—this time from Thayer Academy from Boston. They were guided on an immersive walk through the forest by Erid Román Rosario, who brought the ecosystem to life through stories about its flora, fauna, and the regenerative practices we’ve developed over the decades. Eric is part of a new wave of passionate young people stepping into leadership roles here.

We’re especially excited to be encouraging Erid, who is beginning to explore our forests in depth and share that knowledge through guided walks. After many years of 3t leading tours, it’s deeply rewarding to see the next generation stepping up. This not only supports our work at Las Casas de la Selva, but it also ensures that the knowledge, care, and spirit of the project continue to grow beyond a single person’s efforts.

These visits are exactly why we do what we do—because when young people step into this forest, when they stand on this land and breathe in the humid air of resilience, they begin to understand something vital about the relationship between humans and nature.

Huge thanks to the Shoulder to Shoulder team, group leaders Brian Sweeney and Adelina Valle Martinez, the teachers and leaders who accompany these students, and to the young people themselves—who showed up with open minds and generous hearts.

We hope they carry a piece of this forest with them wherever they go.

Shoulder to Shoulder’s mission is to nurture “ethical leadership” by placing students shoulder‑to‑shoulder with grassroots nonprofit leaders tackling real-world issues—like climate change, gender equality, food security, healthcare, and Spanish-language immersion. If you know a motivated middle or high schooler eager to grow through service, Shoulder‑to‑Shoulder might just be the transformative journey they need.
