Students and faculty from Kutztown University visit BFREE to initiate research projects focused on the endangered Yucatán black howler monkey

Drs. Chris Habeck and Matt Stone and four Kutztown University students majoring in Environmental Science (Corinne Ruggeiro and Nicole Prantow) and Biology (Stefan Grove and Sherry Jimenez) visited BFREE during January 2022 to explore the calling behaviors, movement patterns, and functional role that the endangered Yucatan black howler monkey plays in the neotropical forests of Belize. Here is their story.

By Dr. Chris Habeck

Monkeying around with climate change: howler monkeys and carbon sequestration in the tropical biome 

We are witnessing dramatic shifts in global climate brought on by human population growth and technological advancement. Deforestation and the use of fossil fuels is causing global temperatures to rise, more extreme weather events, and severe pressures on the natural resources needed for the maintenance of biodiversity. Carbon is at the heart of these problems. When fossil fuels are burned and land is cleared through deforestation, the concentration of a potent greenhouse gas, carbon dioxide (CO2), increases in the atmosphere. Greenhouse gases are not inherently bad. In fact, they allow life to exist on this planet by regulating global temperatures within physiological requirements. However, the abrupt increase in atmospheric CO2 over the past several decades is alarming in that species and ecosystems are struggling – often unsuccessfully – to cope with the rapid environmental changes. Scientists are currently on the hunt for strategies to mitigate the impacts of climate change. Obviously, a reduction in fossil fuel use and land clearing are options to slow the increase of atmospheric CO2, but we also need to prioritize the removal of excess CO2 that is already in the atmosphere to minimize the current impacts of climate change. One way to achieve this goal is to maximize the ability of natural systems to sequester carbon from the atmosphere for long-term storage. Protecting tropical forests may be an important part of this process.

Tropical forests represent the largest biological pool of carbon on Earth. Unlike temperate and boreal systems that hold most of their carbon in the soil, most of the carbon in tropical forests is locked up in living biomass, primarily trees. Trees sequester carbon via photosynthesis and store much of it as wood for structural support as they reach to the upper canopy in search of sunlight. In their quest for solar energy, some trees store more carbon than others because of differences in wood density. Wood density is a measure of wood mass per unit volume, often expressed as g/cm3. Trees with high wood density values store more carbon. For instance, trumpet trees (Cecropia peltata) and inga trees (Inga pezizifera) have wood densities of 0.3 g/cm3 and 0.61 g/cm3, respectively. As such, forests dominated by inga trees would store twice as much carbon than forests dominated by trumpet trees. But which processes promote tree communities with high wood density how might we leverage those processes to maximize the carbon sequestering capability of tropical forests in general?

We think the Yucatàn black howler monkey (Alouatta pigra) has an important role in this process of carbon sequestration. Howler monkeys consume many fruits found in the upper canopy of tropical forests. The fruits of trees consumed primarily by howlers tend to have large seeds and large-seeded tree species tend to have relatively higher wood density than smaller-seeded tree species. As such, we think the selective feeding behavior of howler monkeys could enhance the carbon sequestering capacity of tropical forests. Put another way, if we allow this endangered primate to go extinct, we not only lose an iconic species, but also the functional benefits of their presence.

In January 2022, we traveled to BFREE to initiate a long-term research project with the goal of understanding if and how howler monkeys influence carbon sequestration. With the expert help of Ranger Sipriano Canti, we located several howler monkey troops and documented the identity and size of tree species under tree canopies where they were feeding and in random locations away from their activity centers. By measuring the girth (diameter at breast height) of the trees and referencing a wood density database, we used allometric models to estimate the carbon stored as wood. Preliminary results suggest that carbon storage under monkey activity centers is twice that of random areas of the forests, supporting the idea that howler monkeys provide a key functional benefit at BFREE. Our plan is to continue to document the influence of howler monkeys at BFREE to more fully understand how they contribute to the enhancement of biodiversity and ecosystem function.

Working at BFREE is exciting, not only because of the important research questions that can be explored, but also because faculty and students can immerse themselves in the biological and cultural diversity of Belize. We appreciate the kindness of all the BFREE staff and their openness in sharing their knowledge with us. The support we’ve received from everyone is amazing and has contributed to our desire to plan and execute long-term research projects at BFREE and continue to run our winter study abroad program. Also, BFREE is beautiful. The diversity of animal sightings is astounding, from jaguar tracks and scat to flocks of scarlet macaws and night walks with sightings of kinkajou, snakes, frogs, and insects – this place inspires. The work that BFREE does to protect this special place and their role in promoting biodiversity research and education is a benefit to us, our students, and society at large.

Student Groups Return to BFREE After Two-Years

It is no secret that the global pandemic has significantly impacted travel. For BFREE, that has meant a drastic reduction in all types of visitation over the last two years from researchers, specialists, eco-tourists, to our annual Field Courses. However, things are slowly but surely changing, and we are ecstatic to have had our very first student groups back at BFREE since February 2020!

Nearly two years to the day since our last student group, we welcomed two groups from an organization new to BFREE, ARCC Gap Year Abroad. ARCC offers summer and gap year programs for students focused on community-driven and community-led sustainable projects around the world. The two student groups visiting BFREE alternated between 5-nights at BFREE and 5-nights on the Belize Barrier Reef. Each group was made up of ten students and two instructors. The groups volunteered with BFREE’s cacao agroforestry program supporting the growing nursery and painting signs for trees on the farm. Additionally, students learned to make chocolate from bean to bar.

Other highlights include being the inaugural guests to sleep in the newest accommodations at BFREE, The Hammock, exploring the Rainforest on a boundary line hike with Protected Areas Manager, Canti, and meeting and learning from all of the incredible and inspiring staff at BFREE.

These students are part of a 70-day program that will take them from the Rainforest to the Barrier Reef, to sea turtle restoration and surfing in Costa Rica, and finally exploring the Panama Canal over the next two months.

What an amazing adventure these students are on – wishing them all a safe and incredible trip!

Below are a collection of photos taken by BFREE staff and volunteers of both the ARCC GAP GROUPS A and B during their time at BFREE in February 2022.

From Seeds to Trees

Flowers that have dropped from a Jobillo tree near Heather’s home at BFREE.

A couple of years ago, the Jobillo tree next to the house where I live at BFREE, began dropping flowers. The dry season was in full force, so it must have been around May when I noticed the first bunch of delicate, perfect, pale, white blooms. I collected a few out of curiosity and asked Jacob what they were. I learned that the flowers, which detached from the tree in clumps before falling/ floating to the ground, were the tree’s method of seed dispersal and that this only happened every few years. I was fascinated by the perfect central seed that the flowers protected and transported to the earth. Jobillo (sometimes called Tigerwood) is an unusual species of tropical hardwood that has a dark orangish-red cast to the heartwood and is streaked with dark brown to black “tiger stripes.” Jobillo is native to Central and South America and is in the genus of flowering plants in the cashew family called Astronium.


That year, Jobillo flowers soon covered the ground near the house and I began collecting them in my trusty yellow bucket. I spent hours over many days separating seeds from flowers. In the end, I had thousands of seeds and was enthusiastic to plant and share these rare treasures. I placed several hundred seeds in bags in the BFREE plant nursery and still I had thousands remaining, so I divided them into several bags and gave them to our closest neighbors at the Gomez Sawmill and to anyone else who expressed interest.


My enthusiasm was perhaps appreciated but not necessarily shared. Not because Jobillo isn’t beautiful and valuable – it is both of those things – but because it has several innate challenges. Its irregular grain and alternating layers of hard and soft wood make Jobillo difficult to work with. Also, it is exceptionally slow growing. Trees on the property that are known to be nearly 20 years old are tall but only 10-12 inches in diameter. Still, a few dozen of my trees were planted within the cacao agroforestry project in order to add some variety and some long-term shade. The rest were left to grow in the nursery and cared for along with the other nursery plants. To our surprise, last month when Jacob received a phone call: a Belizean woman from Cayo heard we have a nursery and might have some unusual hardwoods for sale. She was particularly interested in Jobillo.


After several phone calls, arrangements were made for her to purchase 130 of our Jobillo saplings. I was thrilled! The truck was loaded with plants plus a few extra for good measure and we drove out to meet Lavinia and her daughter.


Lavinia owns a nursery and was gathering the trees for a client doing a reforestation project in northern Belize near the Mexican border. She surveyed the condition of the trees and we asked if they met with her approval, she slowly nodded. “The leaves are so pretty I could put them in a salad.” She and her daughter laughed and she added, “We are plant-based, so everything green looks like our next meal.” During our brief interaction, Lavinia told us that she wants her nursery to encourage people to plant more trees and food plants. During the pandemic, she has been surprised that more Belizeans didn’t take the opportunity to start producing their own food in home gardens. She has also noticed that there are many areas throughout Belize that were damaged by fire but have never been replanted. Her motto for her nursery is “Planting up Belize.”

Lavinia’s interest in the plants and trees produced at BFREE and her concern about the loss of green areas throughout the country, reminded me of the critical and continued role BFREE’s forests can play in producing seeds and saplings for the future, not just of this property, or of the Toledo District, but for Belize in its entirety.

A Little About Me
I was born in a subtropical climate during the rainy season in my native village of Golden Stream. It is located along the main highway, a couple of miles south of the BFREE junction. I do not remember much of my childhood, but I sure remembered how much my parents loved, cared, and supported me throughout my childhood. I attended primary school graduating as a salutatorian. I moved on to high school with a mindset of “Oh, I’m just gonna do whatever.” I wasn’t involved in anything. After graduating from high school, I wasn’t planning on going to college, so I stayed home doing chores and other temporary jobs such as construction, woodwork, and maintenance. Over that period of time, I attended summer camps with Ya’axche Conservation Trust, whereby I first started to develop a sense of interest in nature.

The following year I applied to Independence Junior College, majoring in Natural Resource Management (NRM). It took me a little while to commit myself to education but, once I did, I was invested despite the lack of internet access and technology at home. While attending college, I became extremely involved on campus by volunteering to plant trees and attending clean-up campaigns with non-governmental organizations like the Toledo Institute for Development and Environment (TIDE) and Oceana.

Most of my favorite hobbies are related to the life of an environmentalist. I like nature walks, night hikes, mountain climbing, canoeing, traveling, photography, and snorkeling. Soccer is my favorite sport simply because it helps me stay active, allows me to socialize, and for the most part, it assists me in clearing out stress. I’m an easy-going individual who is focused on conserving the environment and developing advanced photography skills.

First Memory of BFREE
My first memory of BFREE was one and a half decades ago when I was a kid attending primary school. I remembered coming to BFREE on an educational school trip where I first witnessed Mr. Jacob Marlin display an amazing activity where he captured a venomous snake called a fer-de-lance. He was so generous that he gave us the experience of touching the snake, which is impossible for a child to do on its own. That was one of the greatest experiences I have had as a child.

Another Visit to BFREE during College
During my years of study at Independence Junior College, I never imagined I would be working for BFREE one day. Not that I wasn’t interested, of course, I always thought about it during the final days of the last semester at IJC. What really motivated me was attending a school trip here at BFREE, whereby a sensational occurrence happened. Guess what? We were the first set of IJC students to get the opportunity to see the Harpy Eagle with our sharp, naked eyes. So that wonderful experience made me curious and more interested in wanting to work and join the BFREE family to help support mother nature.

Over the Next Two Tears
One of the things I have noticed about BFREE is that it has been providing opportunities for the Fellows to improve their writing skills by allowing them to participate in helping write reports and grants. This is interesting to me. I am also interested in working with researchers, which allows the Fellows to meet new people while also learning advanced research assessment skills, which could be useful both for the organization and a Fellow’s own career.

What I like About Cacao-Agroforestry
With cacao-agroforestry, I’m most interested in how interplanting cacao trees, along with shade trees that bear fruit and other hardwood trees, attracts different species of birds and other animals. Programs like this, which seek to regenerate the rainforest, are both beneficial to our well-being and also to the environment. Healthy forests provide us with cleaner air and also, ultimately, prevent animal species from going extinct. Separately, the program also allowed me to unlock a skill of mine I never knew I had, which is grafting cacao trees.

First BFREE Cacao Fellow Completes Program!

BFREE Staff celebrate Lenardo’s last day as the Cacao Fellow on Thursday, August 19th.

BFREE’s first Cacao Fellow, Lenardo “Leo” Ash, is graduating from his two-year work-training program this week. He will immediately begin studies at the University of Belize, where he will work toward his Bachelor of Science in Natural Resource Management. Lenardo began his Fellowship in July 2019 under the mentorship of Cacao Program Director, Erick Ac. He spent the remainder of that year “learning by doing” and was completely immersed in all things cacao agroforestry. By early 2020, Leo was well-versed enough on the topic that he was able to start co-presenting to BFREE’s visiting students and researchers.

In March 2020, the COVID-pandemic closed BFREE to visitors and a by-product was the uncertainty of the continued employment of all of BFREE staff. When land borders closed, Erick Ac was no longer able to travel from Guatemala to Belize to oversee the cacao program. Unfortunately, the academic components of Leo’s program fell to the wayside for a while as BFREE’s administrative staff focused energy on ensuring the safety of the BFREE staff and finding the financial means to keep as many people employed as possible.

In spite of the lost opportunities for his professional development including canceled travel plans, research projects, and conferences, Lenardo showed great determination in maintaining his path toward personal and professional growth. Lenardo began practicing Spanish during virtual weekly meetings with Erick, he birded with other BFREE staff, and he participated in Herpetology 101 learning the Scientific names of all the turtle and lizard species on the reserve. He asked for reading assignments to expand his knowledge on cacao and agroforestry and eagerly accepted any opportunities to give virtual presentations to BFREE audiences.

Because of his strong interest in photography, Lenardo began photographing birds and other wildlife around the property. Last July, he spotted a ten-foot boa constrictor attacking a turkey vulture and immediately ran to get a camera and to notify other staff. Images and videos that Leo took of the predation event helped provide details for a scientific article, which will be published in the September 2021 issue of the Journal of Raptor Research.

Earlier this year, Lenardo was invited to be a part of a research team hired by the Heirloom Cacao Preservation Fund. Along with researchers from all over the world, Lenardo spent nearly six months compiling a literature review that explored cacao genetics across the globe.

Lenardo has never given up his dream of continuing his education beyond his Associate’s Degree, so he applied to the University of Belize and was accepted for August 2021 admission. Although, we are sad to lose such a valuable team member, we are excited about Lenardo’s bright future and can’t wait to see where his journey will take him.

Congratulations to Jaren Serano, BFREE’s first Wildlife Fellow alum!

Congratulations to BFREE’s first Wildlife Fellow alum, Jaren Serano, who recently graduated with honors from Jacksonville University. He completed his Bachelor of Science in Sustainability and Minor in Biology in June 2021.


Jaren helped launch the BFREE Science and Education Fellowship Program in January 2018. With the support of the Turtle Survival Alliance (TSA), Jaren spent the two-years in the new work-training program. He learned to support the operations of the HCRC and he also had the opportunity to glean knowledge from the many amazing visitors to the field station. He participated in and presented to field courses with students from all over the world, he assisted visiting researchers and helped implement outreach programs.


During his second year, he began presenting at professional conferences in Belize. In August 2019, he traveled to Tucson, Arizona with Tom Pop, Jacob Marlin, and Heather Barrett to present at the 17th Annual Symposium on the Conservation Biology of Tortoises and Freshwater Turtles. Jaren’s ten-minute talk received a standing ovation and he was awarded Best Student Presentation. That symposium was critical to Jaren’s next steps because the team re-connected with Dr. John Enz of Jacksonville University (JU) who brings student groups to BFREE. John learned that Jaren was applying to schools in the U.S. to complete his Bachelor’s degree and suggested that Jaren apply to JU.

With the help of an amazing GoFundMe campaign, which many of you supported, and a substantial scholarship from JU, Jaren was able to enter college in January 2020 – just in time for a global pandemic. In spite of many challenges, Jaren excelled in his courses and was an active contributor in the classroom and a role model to other students. During his summers, Jaren returned to Belize and BFREE where he assisted with field research relating to the Hicatee, helped with projects at the HCRC, and, most recently, participated in the TSA-North American Freshwater Turtle Research Group (NAFTRG) turtle survey of the BFREE reserve.

Jaren will begin graduate school at the University of Florida this month. Jaren received a full-tuition scholarship through the Doris Duke Conservation Scholars program and secured a research assistantship to cover additional costs. Jaren will work under the advisement of another BFREE partner, Dr. Ray Carthy, in the department of Wildlife Ecology and Conservation. Jaren’s research will examine how human interventions such as beach renourishment impacts natural coastal processes and resilience. Primarily, he will examine how gas exchange relates to sea turtle nesting, dune building, and carbon sequestration.

We are incredibly grateful to all those who have supported Jaren and cheered him on throughout his journey. A special thanks to Turtle Survival Alliance’s Board of Directors without whom Jaren’s Fellowship would not have been possible. Also, to John Enz and Ray Carthy for being incredible BFREE partners and mentors to the BFREE staff. Thanks to Day Ligon and Denise Thompson for their support and tutelage of Jaren and other BFREE staff over the past few years. Finally, thanks to the many donors who supported Jaren’s GoFundMe campaign. Each and every one of your gifts mattered!

Wildlife Fellow, Jonathan Dubon Embarks on 2nd Year

Jonathan Dubon is the second Wildlife Fellow to take part in the BFREE Fellowship Program. Jonathan began working with BFREE in June 2020, immediately after the shelter-in-place order was lifted in Belize. He assists Tom Pop at the Hicatee Conservation and Research Center (HCRC), and although his program began during the COVID pandemic, his first year has been a productive one.

Under the mentorship of Tom Pop, Jonathan has learned how to feed and care for all turtles at the HCRC. He has learned to look for signs of stress and illness and to collect morphometric data during the bi-annual health assessments. He has worked closely with Tom on several projects to upgrade the facility; the most notable have been improvements to the nesting areas and the water movement.

Additionally, Jonathan has been responsible for updating and managing an ongoing census of the captive population of Hicatee turtles in residence at the HCRC. With hundreds of turtles hatching each year and with the recent turtle releases, this is no easy task. The information is constantly changing, so he has to review the data regularly to ensure accuracy. He has taken on the essential responsibilities of creating quarterly reports of activities affiliated with the HCRC, water quality testing at the HCRC, and managing the weather data for the entire field station.

Working with radio-tracking devices to better understand what happens to hicatee in the wild.

Over the past year, Jonathan has both led and co-presented on several virtual presentations. On August 27th at 12:15 EDT, he will present virtually at the 19th Annual Symposium on the Conservation of Tortoises and Freshwater Turtles. His talk is “Environmental Education and Re-wilding of the Critically Endangered Central American River Turtle (Dermatemys mawii) During the 2020 Pandemic.” He will discuss his role in the newly formed Hicatee Awareness Month planning committee and will highlight last October’s awareness campaign. He will also describe the release of the HCRC’s first re-wilded Hicatee turtles and one of the associated community outreach events. To learn more about attending the conference or to see Jonathan’s presentation visit our partner’s website and register for free here:

https://turtlesurvival.org/2021-symposium/

Jonathan has spent the last month in the field monitoring the movements of 25 recently re-wilded turtles from the 2021 hatchling cohort. He and our partners from Belize Turtle Ecology Lab are radio-tracking turtles to begin to understand how far they travel from their release point, what their habitat preferences are, and how they fare after being released.

In addition to turtles, Jonathan has an interest in snakes and large cats. In his final year as Wildlife Fellow, he hopes to work more directly with the large mammal camera trapping project. With new Panthera cameras stationed throughout the property, his involvement will likely become a reality in the very near future.

Adopt a Cacao Tree

In 2015, cacao beans discovered on wild trees within the BFREE Privately Protected Area were submitted for genetic testing to the Heirloom Cacao Preservation Fund (HCP). The results determined that this could be the original chocolate tree, 100% pure Criollo parentage, grown and revered by the ancient Mayan Civilizations, and one of the few pure wild cacaos known to exist on the planet. The beans were given the designation of “heirloom fine flavor” by HCP, only the 11th chocolate in the world to receive such an honor. Since this designation, BFREE has become an active partner with HCP. As part of HCP’s work, they have generously been providing small grants to BFREE over the past two years to assist with the development of our work to propagate heirloom fine flavor cacao.

Become a Champion of Heirloom Cacao Farmers

We are excited to share that you can Adopt a BFREE Cacao Tree through HCP’s adoption program to champion heirloom farmers and families around the world. Adoptions are either a one-time payment of $180 US (or 12 monthly payments of $15 US).  For each adoption, you will receive a digital personalized adoption certificate, an Information card including the farm overview, location, and photo of your adopted cacao tree, and three (3) bars of fine chocolate made from the Heirloom Cacao farm where your adopted tree lives.  

Adopt a tree from BFREE by selecting “HCP #11, BFREE Demonstration Cacao Farm, Belize” at the link below!


The Heirloom Cacao Preservation Fund

HCP was established in 2012 with the mission to “identify and preserve fine flavor “heirloom” cacao for the preservation of biological diversity and the empowerment of farming communities.” Launched in partnership with the USDA and the Fine Chocolate Industry Association, HCP was formed in response to the global pressures of environmental change, deforestation, and economic influences threatening the world’s supply of high-quality, flavorful cacao. Recognizing these endangered cacao trees are the foundation for not only delicious chocolate but also the livelihood of many farmers and farming communities, the HCP is the first initiative to identify and map the world of high-quality, fine flavor cacao and certify growers of these endangered trees.

Congratulations Drs. James Rotenberg and Vibeke Olson on your retirement!

Vibeke Olson and Jamie Rotenberg

Congratulations to long-time BFREE supporters, field course leaders, researchers, and adventurers, Drs. Jamie Rotenberg and Vibeke Olson on their recent retirement from the University of North Carolina Wilmington. Extraordinary husband and wife team, Jamie and Vibeke, have been visiting BFREE for nearly two decades as professors bringing field courses, as researchers, with their graduate students, and as supporters. 

Their impact on BFREE has been significant. BFREE is a better place because of Jamie and Vibeke. So from your BFREE family, congratulations! We look forward to this next chapter in your lives and can’t wait to share in a few of your upcoming adventures.


Messages from your BFREE Friends and Family:

From Judy and Dan Dourson, BFREE Staff Members 2006 – 2013:

We first met Jamie (Dr. Rotenberg to most) in December of 2006 in our first few months as field station managers of BFREE.  He arrived along with close friend and cave diver, Sam Meachum, to lead the first of many expeditions into the Bladen Nature Reserve to establish survey protocols for what would be an extensive, long-term study of neotropical migratory birds and the signature species, the Harpy Eagle.  Jamie’s tenacity and determination were on full display when he limped into BFREE after one particularly grueling expedition, hiking over 8 hours through trail-less, brutal terrain to reach BFREE only to discover a very painful broken collarbone.  Dr. Rotenberg’s tireless commitment to the Avian Monitoring and Harpy Eagle study produced numerous grants to fund the study.

By far our most elaborate scientific collaboration with Jamie was in 2016 when Dan became a co-investigator for a National Geographic Waitt Foundation Grant that focused on the potential relationship between land snails (Dan’s research focus) and Harpy Eagles.  With over 30 participants, the expedition was a technological feat that entailed creating a mobile lab to process snails, portable generators hauled deep into the jungle to provide power for advanced drone technology and elite cavers from Poland who dropped into a 300-foot sinkhole during the expedition.

While Dan’s interactions with Jamie would revolve around their shared passion for the biodiversity of this exceptional region of the world, my time spent with Dr. Rotenberg centered on the development and implementation of seven field courses.  In true fashion, Jamie always knew how to shake things up and challenged me to expand my own horizons as Director of Educational Programs at BFREE leading to new field course locations like Crooked Tree Wildlife Sanctuary or Tikal in Guatemala. I met Jamie’s lovely and spunky life companion, Vibeke, while working with them to plan and execute an innovative course for biology and art/architecture majors focused on the art and architecture of Maya archaeological sites and structures and the biodiversity found around these anthropogenic structures.  Another creative collaboration with Dr. Rotenberg focused on Environmental Psychology with both environmental sciences and psychology majors. 
 
Our field course adventures were always informative, stimulating, sometimes challenging, and full of surprises but it was those challenges that strengthened the bonds of what is sure to be a lifelong friendship.  It is with great delight that Dan and I welcome them into the wonderful world of “retirement”.  We look forward to learning more about what new adventures await and how we can participate. To quote my comedian spouse, Dan, “After all, snails and birds rule, everything else drools!”


Jamie and Jacob Marlin proudly hold the 2012 Partners in Flight Award for Bird Conservation that was awarded to BFREE.

From Jacob Marlin, BFREE Executive Director:

From the first time Jamie came to BFREE back almost two decades ago, he has played a key role in so many of our conservation programs. From leading our bird research and monitoring efforts, including the rediscovery of a wild breeding population of Harpy eagles, to training young Belizeans to be bird biologists. His passion for teaching brought hundreds of students from the USA to BFREE on study abroad programs for more than a decade. In 2014, BFREE was honored to have Jamie join the board of directors, where he currently serves as vice-president. Over the many years, Jamie and Vibeke have continued to support BFREE in countless ways, always believing in us and our mission. They are both true partners in conservation. Congratulations to this dynamic husband and wife team!

From Marlyn Cruz Sierra, BFREE Staff Member 2012 – 2014:

 Working along with people who share an incredible passion for what they do is one of those experiences that you will always cherish. For me, Dr. James is that person. He transmitted this passion and love of his work and projects when I participated as an avian technician at BFREE, so it never really felt like “work.” He was always very communicative and incredibly organized. He was unselfish with the wealth of knowledge he possessed, willing to give you an opportunity for growth, and cheering you on while you accepted new challenges.

From Liberato “Gato” Pop, BFREE Staff Member 2006 – 2015:

I would like to say that Dr. Jamie has been a great mentor for me. He has guided me through numerous trainings to become an expert avian researcher. He has always encouraged me to continue what I love and that is working with nature.

I want to thank Dr. Jamie and Dr. Vibeke for their support of our bird banding project for the past years at BFREE.


Jamie and Vibeke pose with students from UNCW during their BFREE Field Course.

From Heather Barrett, BFREE Deputy Director:

I admire how well Jamie and Vibeke have participated in each other’s professional and personal interests over the years. Although they have focused their careers on different continents, they remain a strong team supporting one another by each being engaged in the pursuits of the other. Jamie picked Central America and the sciences for his research while Vibeke chose Europe and the arts for hers. Instead of allowing their differences to divide them, they used them as an opportunity to explore the world together. With that model in mind, I’d say the sky is the limit for their shared retirement. Congratulations, Jamie and Vibeke!


Jamie and Lisa reunited after a decade at a 2017 BFREE Fundraiser in DC

From Lisa Ramsden, UNCW Alum and BFREE Field Course Participant 2007:

Dr. Rotenberg fostered my deep love of tropical ecosystems and birds through his classes at UNCW. I am so thankful that I particpated in his Environmental Psychology course that took students to Belize and that I was able to visit BFREE. It was a truly eye-opening experience for me. I feel so lucky to have taken a variety of classes with him and to have gotten the wonderful experience to intern with him on his Painted Bunting project. Congratulations on your retirement, wishing you all the best!


James and Jamie in Belize

From James Abbott, UNCW Alum, BFREE Field Course Participant and Assistant Researcher:

Congratulations Dr. Rotenberg on your retirement. You have been an amazing mentor to me. I believe that even more than the knowledge, experience, and skills, you passed on to me; the biggest influence I carry with me everyday is your attitude toward life and teaching demeanor and style. Those have and continue to shape my career in environmental education. Not to mention my unofficial role as the painted bunting ambassador to all of southeast VA – our region’s newest breeding bird. I cannot thank you enough for everything you have done for me and I hope we can meet up again someday at BFREE and enjoy a field station harpy eagle together.


BFREE Fellows Participate in Ranger Weekend

BFREE’s Science and Education Fellowship program is a two-year immersive training opportunity for recent Belizean junior college graduates who exhibit leadership potential combined and a clear interest in the conservation of the country’s natural resources. Each Fellows are assigned one of three focal areas based on their interest and experience, Wildlife conservation – Hicatee Conservation, Sustainable Agriculture – Cacao Agroforestry or Protected Areas.


Lenardo Ash (Sustainable Agriculture/Cacao Agroforestry) and Jonathan Dubon (Wildlife Conservation/Hicatee Conservation) are BFREE’s current fellows and have been learning a lot in their focal area. They also have the opportunity to take place in unique professional development opportunities during their two years. This may include trainings, conference attendance, presenting information to groups, and various field experiences.


With strict restrictions due to the pandemic, there were few opportunities for Fellows to travel during 2020. We decided to start the new year off in 2021 by creating training opportunities right here at BFREE. Lenardo and Jonathan joined BFREE Park Rangers, Sipriano Canti and Apolonio Pop for a ranger training weekend. Friday afternoon, the team hiked to their camp spot about two miles from the main facilities. They set up camp and then immediately went to deploy camera traps in the area. The weekend was spent exploring the properties’ many trails while monitoring camera traps and searching for tracks and other signs of wildlife along the way.


The Fellows learned the basics of surviving in the jungle with skills like building a fire and locating water vines. Canti described traditional uses of plants and trees found along the way. The team also updated and posted Private Property signs throughout the area. They explored creeks and lagoons in the area while discovering the many types of habitat that exist within the BFREE property.

BFREE Fellow, Jonathan Dubon during the Ranger Weekend in January 2021.

Some highlights for Jonathan were visiting a pretty lagoon where they saw an Agami Heron. Canti named it “Live Lagoon” because of the little spring that supplies the lagoon with fresh water. Jonathan was also excited to capture an image of a male Tapir on one of the camera traps they set. Volunteers and interns have always loved Ranger Weekends at BFREE, and we are excited to extend this opportunity to BFREE Fellows for the coming years!
