Nursery Build 2021

In early 2021 Tropic Ventures Research & Education Foundation partnered with Naples Botanical Garden in Naples, Florida, to prioritize efforts to conserve on-site species most at risk from extinction through seed banking, multiple off-site backup collections, development of propagation protocols, assessment of extinction risk for the IUCN Red List, and out-planting on the site. The Association of Zoological Horticulture provided a grant towards this endeavor. AZH is a non-profit membership organization dedicated to the advancement of horticulture in zoos, zoological parks, botanic gardens, and aquariums.

Architect David Henebry, who has been volunteering his time and building skills at Las Casas since 2018, designed the nursery, and in March 2021 arrived on a 10 day trip, and with a team effort including 3t, Axel Rúa, & Diego Marvel, a strong, hurricane-resistant shade-tree nursery, and a small soils shed came into being, along with a 10’ x 10’ seed nursery, which is still in progress.

As a result of this partnership, the Botanic Gardens Conservation International via the Franklinia Foundation, & the Global Tree Campaign have started a new collaboration with us to survey for endangered endemic trees of Puerto Rico. We are over the moon about this.

BGCI is a registered charity and company in England and Wales, and in the U.S. as a 501(c)(3) non-profit organization.

Chad Washburn, Director of the Naples Botanical Garden, will join us in the field later in 2021.

at Las Casas de la Selva, 22nd April 2021

On Earthday 2021, a team of intrepid plant experts will spend the day in the Las Casas forest on a major survey, to scout for rare and endangered endemic species, and to identify everything along the journey. The team will identify trees, shrubs, lianas, grasses, bryophytes, fungi, fauna, and whatever else they find!!

Las Casas de la Selva is collaborating with Botanic Gardens Conservation International via the Franklinia Foundation, a private foundation established in Switzerland. BGCI is a registered charity and company in England and Wales, and in the U.S. as a 501(c)(3) non-profit organization.

Chad Washburn, Director of the Naples Botanical Garden in Florida, USA. NBG is working with the team at Las Casas de la Selva throughout the process, and will join them in the field later in 2021.

In January 2021, Las Casas de la Selva successfully applied for a grant through Naples Botanical Garden to build a shade tree nursery at the project. The Association of Zoo Horticulture, (AZH), provided this grant.

2021 Innovation Award: Yale (ISTF) 2nd Prize

Since 2014, the Yale University Chapter of the International Society of Tropical Foresters (ISTF) has awarded an Innovation Prize at its annual conference to honor outstanding initiatives and ideas related to tropical forest use and conservation.  

Three ISTF Innovation Award finalists were selected to present their exceptional approaches, experiences or efforts relating to the 2021 ISTF Conference theme: “Timelines and Critical Junctures: Re-examining Crises as Opportunities for Change.” The finalists participated in a live pitch event over Zoom on Friday, February 19th at 13:00, and on Saturday 20th February, votes were counted.

Thrity was selected as one of three finalists to tell the story of Las Casas de la Selva, Puerto Rico Hardwoods, and the Institute of Ecotechnics. She represented all her colleagues and friends, people that have been involved for decades with these long-term environmental projects.

3t’s presentation: “Re-examining Crises as Opportunities for Change: Sustainable Forestry, Log salvage, & Hardwood production  after extreme social, ecological & technological disturbances in Puerto Rico” won second prize.

Established in 1983, Las Casas de la Selva (LCS) Sustainable Forestry Project planted 40,000 hardwood trees on 300 acres to explore viable alternatives to clear-cutting and short-term exploitation of tropical rainforest. We are demonstrating planting valuable hardwoods within secondary forests can reduce pressures on primary forests. Silvicultural techniques developed and applied at LCS over the last three decades show that enrichment planting of secondary forests maintains ecological diversity and health, while providing economic returns from sustainable timber production.

Puerto Rico, currently facing incredible economic distress, is awakening to the potential of sustainable use of its forest resources. Forest cover, just 6% in the 1900s, has grown to 60+% through tree planting and natural regeneration of abandoned short-term farmland.

 Since 2015, Puerto Rico Hardwoods had been salvaging tropical hardwood trees destined for chipping/dumping at huge cost to Puerto Rican municipalities. Thousands of valuable mature trees fell during Hurricane Maria.  The PRH team quickly started reclaiming logs, reducing the amount of waste going into overburdened landfills, transformed salvaged timber into value-added products, creating jobs, stimulating the economy, and demonstrating the value of wood!  

Hurricane Maria was a devastating social, ecological, and technological crisis, providing a moment of huge learning. Novel approaches are necessary to build resilience and adaptability to large-scale disturbances. We have an opportunity to create new potentialities for PR’s mass debris removal after extreme events potentially powering the rebirth of the island’s lost wood industry. This is crucial since extreme weather catastrophes will be more frequent and of greater intensity in these unstable Anthropocene conditions.

Fare forward traveler.

We are so sad to share the news of the passing of Sally Eva Silverstone, also known as Sierra, who was the director of Las Casas de la Selva from 1997 to 2007.
On 24th September 2020, she passed away in Bali, where she has lived for the last decade working with the Biosphere Foundation.

I met Sierra in 1999, having arrived at Synergia Ranch full of the excitement of a three-year voyage on the RV Heraclitus. I was ready for anything. For four years we were co-chefs on the annual 2 weeks African Drum & Dance Bantu Festival. I remember the day Sierra asked me if I wanted to go to Las Casas de la Selva to help her run Earthwatch Teams. I knew very little about the project, but suddenly I was planning a whole new life adventure. Christmas in Puerto Rico. I jumped in whole-heartedly and arrived in a rainforest, culture, and country I knew nothing about. Soon I was working with Sierra on regular trips from Santa Fe to PR at least four times a year.
Sierra and Mark had made a successful proposal to The Earthwatch Institute to survey the hardwood plantations of the project. Sierra had been involved in the early 80s when the tree planting started, and 40,000 valuable hardwood trees were planted at that time. We spent many happy hours in the forest leading teams of citizen scientists from all over the world, measuring hundreds of trees over several years, and I always admired Sierra’s forthright way of dealt with everyone, and we had a few nutters who signed onto Earthwatch Teams along the way! I learned so much about the forest at that time.

Sierra always encouraged me in everything at Las Casas, and in 2003, we headed up our first harvesting of Blue Mahoe, with a small crew. In 2004 Sierra gave me the reins to take on the wood production side of the project, and we carried out another successful harvest, milling, and drying. I give thanks today that Sierra had confidence in me and gave me the freedom to manifest. That manifestation continues today, and I know that Sierra, wherever she is now, is beaming and nodding her head at the project’s blossoming.
Fareforward traveler.

Elegy to Sierra

What is the measure of a life well-lived,
How to say what gave her pleasure
Or to the watching world gave meaning?
Was it trees and plants that grew
Remembering the gardener that was you
Or laughter tinkling in the air,
Echoes of you who once was there?
Or drums and bells the living made
To honor you once you were gone,
The chants and songs the community sang
To carry you on your way, to tend the flames,
To transform our body into diamond dust,
Then launch your swan upon the Silver Sea
Such tenderness and love,
I couldn`t wish more for me!

Richards Druitt

Here is an album of images to share together as we remember dear Sierra.

Chainsaw Training Workshop at Las Casas de la Selva

Hurricane Maria in 2017 killed many of the Pine trees (Pinus caribaea var. hondurensis, known as Caribbean Pitch Pine or Honduras Pine) on the 600m elevation ridge-tops of Las Casas, and they are dead but standing.

In March 2020, the team from Puerto Rico Hardwoods closed the wood-yard in Caguas and spent the day bringing down standing dead Caribbean pine trees. This wood was milled into 2x4s for a special project. This was a great opportunity for training the crew in directional felling, using ropes, and learning about harvesting trees, and all the safety procedures. The crew were trained by, led by Andrés Rúa, and Rafael Pérez.

Pinus caribaea was planted at Las Casas de la Selva in the early 80s, favored by the PR Department of Natural Resources, and chosen for its fast growth, and ability to grow on virtually all soil types. The soil on the ridges are clay and the land was heavily grazed for many years. Now 35 years later, in 2020, we can see that the trees did grow fast and well, but unfortunately there would never be a market for the wood in Puerto Rico. 3t and Andrés have been trying for many years to create a market for the pine, have used it on several projects, but its sale has been limited.

About this pine: Pinus caribaea var. hondurensis was introduced into Puerto Rico in 1959, and was introduced intentionally to be used for erosion control, and as windbreaks. The heartwood is a golden yellow to brown, with highly defined straight grain, and a light yellow sapwood. Straight resinous canals streak the wood. The wood exudes a large amount of resin, making it less suitable for joinery and flooring, and limiting its value as a timber. Nevertheless, it is used for a wide range of purposes, including construction, light flooring, joinery, inexpensive furniture, boxes, pallets, turnery, toys and, has in other countries been used after treatment with preservatives, for poles, posts, and railway sleepers.

Pepperdine University at Las Casas de la Selva

Pepperdine University students spent 8 days with us in February, and for several days we cleared the homestead of vines, worked on trails, and created new nursery areas. Alex Johnson was the team leader, and Alex has already volunteered twice before at the project. Thank you team, we really value our collaboration with Pepperdine. Maria Cristina, from Cayey, cooked wholesome and hearty meals, and Ana Pagan from Patillas, held a wonderful salsa dance class.

We were joined for the final days of this team by Professor of Architecture, Seth Wachtel, who was planning a trip for students from the University of San Francisco in May 2020.

As February drew to a close, there were whispers of a virus spreading rapidly over the globe. On March 12, 2020, the World Health Organization declared a global pandemic. On March 15 a severe lockdown was ordered by the Governor of Puerto Rico, as SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), became a household name! The January 2020 earthquakes had already caused the cancellation of several of our regular university teams for 2020, but with the lockdowns, all our teams cancelled; our brief time with the Pepperdine students was so valuable.

Dog Training Team at Las Casas de la Selva

Debbie Jacobs has been organizing travel adventures for nearly three decades, including leading group adventures to Puerto Rico. She has been bringing various groups to Las Casas de la Selva since the 90s.

She has always been foremost a dog trainer, and finally about four years ago realized her dream of organizing dog-training groups to visit Puerto Rico. She is excited to be combining her passion for traveling and sharing unique environments with people, along with her enthusiasm for helping pet owners discover the most effective and humane ways to communicate with their dogs. The team also travels to animal sanctuaries and shelters, where they train the staff and animals, helping with the stray dog situation that is ongoing.

Part of Debbie’s ten-day Puerto Rico trips includes several days at Las Casas. During the day, she offers the latest animal training techniques and shares them with her team. Getting people to visit Las Casas is always a good thing, and gives us the chance to spread the word about the work we do in sustainable forestry. We also invite our friends who have dogs that need training. It is actually the case that the humans need as much training as the animals! By showing people how to have a positive and trusting relationship with their pets, they support dogs in doing what they can do so well – become our best friends and treasured members of our families. Having our own dogs makes Las Casas a favorite place for Debbie’s team, and Negralora, Nogal, and Yagrumo get to learn best behaviors as a result of this positive reinforcement training. Kailash, our 15 year old cat is also trained in various ways, (yes, you can teach an old cat new tricks!), as well as some of the chickens!

Debbie’s trip is a perfect combination of community service, dog training skills, education and practice, and flat-out fun. Delicious meals were cooked by 3t and a up-lifting salsa dance class by Yari Soler.

Professionals in the industry she has trained with include Jean Donaldson (, and Bob Bailey. Debbie is also currently studying to become a Registered Behavior Technician, an international certification that indicates she is qualified to work with Board Certified Behavior Analysts in implementing behavior modification plans with people.

Debbie Jacobs, CPDT-KA, CAP2, is the author of ‘A Guide To Living With & Training A Fearful Dog’ and ‘Does My Dog Need Prozac?’

Jovany, 19, from Port-au-Prince, Haiti, won a scholarship from Greenheart,and volunteered at Las Casas de la Selva in January 2020 for 10 days. He was a great volunteer and jumped enthusiastically into all tasks that he was given, including pruning in the gardens, and helping to host a visiting team.

2019 Work on new Tree Nursery

Hurricane Maria devastated the Las Casas de la Selva homestead including two tree nurseries. 3t lost nearly 2,000 tree seedlings and saplings in the hurricane, a soul-destroying loss of many years work. The creation of a new nursery was the great healing of 2019. Many collaborations with volunteer groups, and a collaborative plant project were terminated as the project struggled to survive 9 months without electricity, and a compromised homestead and road. In the hours before the hurricane, as she watched internet images of Maria heading to the island, 3t saved a few dozen critically endangered endemic trees, and dug out some that had been freshly planted out, and secured them in the workshop, along with everything else necessary to save. The workshop had survived Hugo and Georges. It survived the eye of Category 4/5 Maria. Sadly much else was lost. See short movie below.

Images from 2019 volunteer work on the new Tree Nursery. Thank you everyone who has helped us with this project. Special thanks to architect David Henebry, who directed volunteers, designed and built the hurricane-proof roof, Chris D. Miller for all his labor, Greenheart Travel who helped weed-cloth the ground, and gravel it, & Globalworks, who helped mix and pour the concrete floor. As well, to the individual volunteers who helped, we salute you all.

We are still dealing with the aftermath of Hurricane Maria, and we need help. Please let us know if you can help by making a donation towards our work in the rainforest. Thank you!

2019 Americorps Groups at Las Casas de la Selva

Thank you to Americorps for sending volunteer groups to help us with tasks. Mostly we were working on the forest roads and trails, but also on some construction and a workshop clear-out. We really appreciate these teams and thank each of you who were part of the 2019 teams!

2019 Volunteer Groups

A huge thank you to all our 2019 volunteer groups! We could not have done it without you!

Thank you everyone! Have a great start to 2020!

Thank you to all our 2019 volunteers!!

To all our 2019 volunteers. It takes a lot to keep a project alive. We salute you for all your help. Thank you!!
All volunteers worked on a variety of tasks including grass-cutting, ditch digging and erosion control all over the homestead, main-drive roadwork, forest roads & trails; pruning back the overgrowth; maintenance of the wastewater garden; compost piles; clearing out the workshop; homestead maintenance; nursery establishment, concretework, & tree-planting.

David Henebry, architect working in PR for a year, came to Las Casas de la Selva, for a day, volunteering on a garden digging project with an AmeriCorps youth team. From there, David went on to completely fund, and re-build several critical areas of the homestead facility, coming in on Sundays. In between digging holes, carrying tree saplings, planting, and digging, David also completely rebuilt the roof of El Teatro, and installed half of a new floor. He repaired a broken roof on a casita, made a new cement floor for outside the Casablanca bathroom, and built a hurricane-proof lean-to next to the workshop, for the new, improved tree nursery. We are very, very grateful. 3t lost nearly 1,500 tree seedlings and saplings in the hurricane, a devastating loss of many years’ work, so the energy into a new nursery this year was a great healing of 2019.

Chris Miller, spent three months living at Las Casas de la Selva, and he worked closely with David on all the tasks, as well has putting in heroic efforts to keep the grass cut on the homestead, which had become a huge task after the hurricane with the homestead becoming a sunny location after being a shady grove for many years as the trees grew. We are so grateful to everyone who has helped us here this year: Chris Miller, David Henebry, Sarah Dean, Alex Johnson, Dayne Taylor, George Locascio & Miho Connelly, Anna & Fred, Anna & Joy Brown, Bill Davidowski, Bruce Mobley, David Anderson, Daniel Mobley, Tial Neal, Yogani Govender and friends, Gordon Weber, Noel Moore, Clara King, Katie Tsui, Robert Lane, Harry Zubik, Jess Tabac, Shari Dee, Sönke Scheel (Muller), and Elizabeth Whitehouse.

We could not have done it without you all. We appreciate your love and support very much! Thanks also to James Beezley for a generous donation in 2019. Blessings to all as we move into the New Year 2020. Please keep in touch and drop us a note!

Happy Birthday to Frank H Wadsworth 104 years old today! Nov 2019

To our favorite forester, Frank, who turns 104 today. Thank you for all the inspiration you have given to us over many years now. Happy Birthday!!

No Escape: The Reality of Climate Change Here & Now, Oct 2019

Landmark meeting on the impacts of climate change, and the urgent need for action

On October 30, 2019, at the Luis Muñoz Marín Foundation (FLMM), a symposium brought together prominent scientists, environmental managers, educators and citizens concerned about the best way to adapt to the reality of climate change. The symposium entitled “No Escape: The reality of climate change here and now” featured 20 presentations, one 1-hour expert panel discussion, and 13 exhibitors of various topics focused on climate change, including environmental health, agriculture, forestry, management of urban areas, the built environment, socio-economic impacts, resilience, coastal erosion, research in areas such as El Yunque National Forest, climate change awareness education, and risk mitigation processes, among others. The event included international participants, such as Sir Ghillean Prance, former director of the Royal Botanic Gardens, Kew in the United Kingdom, as well as a large number of prominent speakers from Puerto Rico, the Virgin Islands, and the United States. Response to this free public event was remarkable, and seats were fully booked out a week before the event. Over 300 people attended the event throughout the day that lasted from 8am to 6pm. For a full list of presenters, presentation abstracts, and symposium schedule, please consult the conference program, shown below.

Introductions were provided by the symposium’s three organizers: Ms. Thrity J. Vakil, FLS, director of the Institute of Ecotechnics, US, director of Tropic Ventures Sustainable Forestry and Rainforest Enrichment Project, Patillas, PR, and President of Puerto Rico Hardwoods, Mr. Christian Torres Santana, Director of the Parque Doña Inés, and Ms. Cristina Cabrera, an environmental consultant and project manager.
