Unity and achievement: more than just a visit

This week was a blend of effort, enjoyment, and education. Under the warm Puerto Rican sun, we worked alongside an incredible group of teenagers from Fountain Valley School. They showed remarkable enthusiasm and dedication in every task, contributing significantly to our environmental and community projects.

A heartfelt thank you goes to Suzanne Tibbets and Blake Pelton, the dedicated school staff members who guided and cared for these amazing teens throughout their stay. Their leadership and support were pivotal in making this experience a success for everyone involved.

Culinary delights and teamwork

We extend our gratitude to Monique Nieves for providing delicious and nutritious meals that fueled our days. Her culinary skills kept everyone happy, healthy, and ready for the day’s challenges. A special shout-out to Mercury for his invaluable assistance in the kitchen and with various crew-work tasks—your help was indispensable.

Celebrations and learning experiences

One of the week’s highlights was a musical birthday celebration, featuring the talents of guitarist Andrés Rúa, and flautists Nina Assimakopoulous, and Raquel Torres-Arzola. Their beautiful music added a magical touch to our evening, which was also a birthday for two of the students, creating memories that will last a lifetime. Thank you for sharing your artistry with us.

We also extend our thanks to Andrés Rúa and Joerge Jahn for their engaging woodworking show and tells. These sessions were not only educational but also inspiring, offering a hands-on experience in craftsmanship and highlighting sustainability.

Environmental impact

Throughout the week, our collective efforts focused on environmental conservation and improvement. Together, we planted trees in various areas, including in an area affected by a landslide, cleared and organized the nursery, potted 250 vetiver slips, cleared invasive vines from a new planting of vetiver, and dug a significant trench for a new retaining wall at the lower homestead. Each of these tasks is vital to our ongoing efforts to protect and enhance the natural beauty of Las Casas de la Selva.

Heartfelt appreciation

As we say goodbye to another memorable visit, we want to express our deepest gratitude to each individual who contributed to this special week. Your hard work, enthusiasm, and spirit of cooperation have left a lasting impact on our community and the environment. To the students and staff of Fountain Valley School of Colorado: thank you for continuing this wonderful tradition. Your visits are a highlight of our year, and we look forward to many more to come. Here’s to the next decade of friendship, growth, and making a difference together!

Tree-planting! Feb 2024


In February 2024, we were fortunate to host a vibrant group of thirteen-year-olds from Cathedral Middle School for Boys in San Francisco. Under the dedicated guidance of Chris Corrigan, Maddie, and Steve, these young students embarked on an enlightening journey into the world of environmental stewardship.

Their invaluable contribution to planting mahogany saplings, cacao, coffee, and vetiver has made a significant positive impact on our environment.

They worked in the rain and saw first-hand the impact of Hurricane Fiona’s devasting dump of water in September 2022, which caused the landslides that we worked on. We planted Mahogany (Swietenia aubrevilleana) saplings, grown from our own seeds, in June 2022.

Among the many activities, one aspect that stood out was their engagement with our compost toilets! This experience was more than just a lesson in sustainability; it became a source of inspiration for these young minds. The students quickly adapted to this eco-friendly practice, understanding the importance of water conservation and waste reduction. Their enthusiasm and willingness to embrace such sustainable living practices were both impressive and heartwarming. The use of compost toilets served as a practical introduction to the principles of ecological responsibility and closed-loop systems.

It was inspiring to see the students not only accept but also appreciate the value of these sustainable practices. They learned firsthand how such small changes in daily habits can significantly impact our environment. Thanks to Thomas for his note.

Special thanks are due not only to the ever-supportive Chris Corrigan but also to the dedicated school staff—Chris, Steve, Maddie—and Globalworks Leader Rebe, who all played pivotal roles in facilitating this transformative experience. Their collective efforts have undoubtedly sown the seeds of environmental consciousness in the hearts of these young individuals.

We extend our deepest gratitude to everyone involved in making this experience a reality. The students of Cathedral Middle School for Boys have left our community richer, not just through their physical contributions to our reforestation efforts but also by reinforcing our hope for a more sustainable and conscious future.

The Cathedral School for Boys prioritizes diversity in ethnicity, race, and socioeconomic status, along with an experiential education focused on service. This ethos of diversity and experiential learning is integral to their curriculum and is bolstered by their tuition assistance program. It is this foundation that facilitated the recent educational trip to Las Casas. The excursion included students from various economic backgrounds, including those on reduced or subsidized tuition, reflecting the school community’s shared commitment to its values. This commitment enables students, particularly those from urban backgrounds, to experience and learn about conservation in the rainforest firsthand, thereby broadening their perspectives and potential life paths.

Huge gratitude to Monique Nieves whose culinary expertise provided us with delicious meals, fueling our days with energy and warmth. Additionally, a big thank you to the talented artist Mercury, whose volunteer efforts and all-around assistance have been invaluable to our cause.

Here’s to more visits, more learning, and more inspiration. Together, we are cultivating a greener, more sustainable world, one young heart at a time. 27-29 Feb 2024

Fountain Valley 13-17 March 2023

An extraordinary opportunity beckoned the students of Fountain Valley High, led by the exceptional math teacher Deb Prantl. Leaving their familiar classrooms behind, they journeyed thousands of miles, plunging into a world as lush as it is mysterious. Their destination: Las Casas de la Selva, a sanctuary nestled deep within the heart of the Puerto Rican rainforest.

Awaiting them was a chance to immerse themselves in a realm of knowledge that far outstripped any textbook. They were there to spend time with Thrity Vakil, or 3t as she is fondly known. A respected director and passionate budding botanist, 3t offered these young explorers an up-close and personal encounter with the incredible biodiversity that thrives in the verdant wonder of the rainforest.

Under 3t’s guidance, they discovered the intricate beauty and delicate balance of the rainforest ecosystem, and projects dedicated to conservation of endemic speces, in collaboration with The Botanical Gardens Conservation International.They learned about two rare and endangered plant species, Palo de Cruz (Garcinia portoricensis) and Tortuga Prieto (Ravenia urbanii). These weren’t just names on a list for the students; they were real, vibrant components of a thriving ecosystem that they could touch, examine, and understand. The students got up close to the critically endangered species being propagated in the nursery. They also got to repot endangered endemic seedlings Guayabota (Eugenia stahlii), from seeds gathered in 2020.

It’s not every day that a math teacher from Colorado Springs brings her students to the vibrant depths of the Puerto Rican rainforest. Deb Prantl, however, is no ordinary educator. Year after year, she chooses to embark on these exceptional journeys with her students, seeing the inestimable value of teaching beyond the classroom. Her vision transforms students from mere observers to participants in this incredible global classroom.

Las Casas de la Selva, under the stewardship of 3t and her team, welcomed these eager students with the vibrant buzz of coquis, the rich scent of damp earth, and the lush greenery of towering trees. The students didn’t just observe the rainforest, they experienced it – its sounds, its smells, and its life – gaining insights that can’t be learned in a traditional classroom setting. This trip wasn’t just a journey into the rainforest; it was an expedition into knowledge, conservation, and a deeper understanding of the world that surrounds us.

The thrill of the journey to Las Casas de la Selva doesn’t end with their exploration of the rainforest. A walk in the woods is just the beginning. The excitement continues as the group congregates for an opening circle – an integral part of the experience, providing an opportunity for everyone to share a bit about themselves and forge connections. With dinner comes more animated conversations, as students and staff exchange stories and perspectives, learning from each other as much as from their surroundings.

The next day, the group gets their hands dirty, literally. They work on clearing a trail near a landslide caused by Hurricane Fiona in September 2022, and another one leading down to the river. They help in repotting rare trees in the nursery and planting out nine mahogany trees, each seedling a promise for the future. They engage with Bill Davidowski, absorbing his insights on woodworking as he unveils his current projects.

All this, fueled by the delectable cuisine of Monique Nieves, bringing the local flavors of Puerto Rico to life with every mouthful. Her culinary prowess complements the rich experiences of the day, nourishing both body and soul.

Witnessing the rainforest awaken to a new day, watching the students’ faces light up as they discover the wonders hidden in the lush wilderness is a sight to behold. From unusual flora and fauna, breathtaking waterfalls, awe-inspiring wildlife, to the melodic chorus of coquis serenading the night, Las Casas de la Selva transforms into an open-air classroom like no other.

The retreat at Las Casas de la Selva is not just an ecological expedition; it’s a journey of connections – with nature, with each other, and within oneself. It’s a sanctuary away from the digital distractions of modern life. Students often express their relief and joy at being off their phones and devices, relishing the chance to simply be in the moment, to absorb the sights, sounds, and sensations of the living rainforest around them.

Beyond the trail-blazing, tree-planting, and storytelling, the Las Casas de la Selva experience is about more profound lessons. Lessons in conservation, sustainability, and environmental stewardship are woven into the fabric of the journey. It’s about understanding that we’re all part of this beautiful, intricate web of life and that every action matters.

And perhaps most importantly, it’s a reminder that sometimes, the best way to find yourself is to lose yourself in the wild. To echo the words of naturalist John Muir, “In every walk with nature, one receives far more than he seeks.” In the heart of the Puerto Rican rainforest, the students of Fountain Valley High discovered just that.

For Tropic Ventures Research & Education Foundation, 2021 began with Naples Botanical Garden in Florida securing a grant from the Association of Zoological Horticulture to fund the building of a new tree nursery at our project in Patillas, Puerto Rico, after the devastation of all our tree nurseries in Hurricane Maria in 2017. Following this, the 2021 Botanical Gardens Conservation International & Global Tree Campaign agreement and grant opportunity to survey for two threatened endemic species was a huge accomplishment; a proposal for the conservation of two Puerto Rican endemic trees, Garcinia portoricensis & Ravenia urbanii. Thrity Vakil, director of TVREF, immediately set about creating a diverse team comprised of plant and tree experts, and experts in the fields of ecology, biology, taxonomy, bryology, mycology, and zoology. (TVREF is also known as Eye on the Rainforest, which is the name of its website).
