This May, a group of researchers from the University of Michigan and the University of California, Berkeley, visited BFREE to do a survey of amphibians and reptiles. They worked for two weeks, both on the BFREE property and at Mountain Pine Ridge Forest Reserve. Between these places, they recorded 47 species. Two of those finds (one snake and one frog) were significant range extensions within Belize.

Iris Holmes, University of Michigan Researcher, measures a snake collected during the survey in the BFREE Lab.

In addition to a biodiversity survey, the researchers collected a variety of data on each animal. They recorded snake anti-predator displays and took high-quality photos to study snake and lizard anti-predator and social color displays. One project focused on how frogs fluoresce in the UV spectrum and found new accounts of biofluorescence in several species.

The researchers also took microbiome samples from frog skin and snake and lizard digestive tracts. These samples will be used to understand the parasites that infect these species, and the bacteria that might help protect their hosts against these parasites. Other researchers worked to test hypotheses the diets of snakes, lizards, and frogs. Understanding what animals eat is key to conserving them – animals can’t survive if they can’t get enough food! The team was happy to find such diversity and abundance in the amphibians and reptiles of Belize. It was a particularly special experience to be at BFREE as the hicatee turtles were hatching.  Watching animals emerge with the first rains of the wet season was a true privilege.

2019 Field Season Wrap Up

We are wrapping up another incredibly rewarding year of hosting field courses at the BFREE Field Station. 2019 brought seven colleges and universities from the US and one from Belize. Altogether, just over 100 students and 20 instructors spent between 4-10 nights at BFREE. They could be found immersing themselves in the jungle hiking both day and night, working on independent research projects,  learning about the critically endangered hicatee turtle, tasting cacao fresh off the pod, swimming in the river, snacking on johnny cakes, and searching for the elusive Harpy eagle. 

Most field courses require students to work on independent research projects in order to receive an introduction to environmental field methods through hands-on learning. Students gain a basic understanding of field methods necessary to discuss and research various environmental issues. Some will come prepared with a question in mind before they arrive at BFREE, however, for many once they arrive with one sweeping view of the jungle, the possibilities of research are endless. Below are just a few examples of the independent research projects students worked on this year. 

  • 1. Are howler monkeys most active at dusk or at dawn?
  • 2. Does the height of the tree determine the size of its buttress?
  • 3. Will the trees near the river or a waterbody grow taller than the ones that are not near a waterbody?
  • 4. Will a foreign liquid throw the leafcutter ants off their trail?
  • 5. Does the higher density of insects/food source in an area coincide with a higher density of birds in that area?

A special thanks to each of our instructors that make our Faculty-Led Field Courses a success. We look forward to having you back next time!

BFREE Receives Porras Conservation Award

  It’s not often international wildlife conferences hold their annual meeting so close to home. Fortunately, the International Herpetological Symposium (IHS) chose Belize City as the base for their 42nd gathering and we are so glad they did!    The International Herpetological Symposium (IHS) provides a forum for the dissemination of information and research pertaining to the natural history, conservation biology, captive management, and propagation of amphibians and reptiles. The symposium provided a valuable opportunity to showcase the herpetological conservation taking place in Belize.    BFREE Staff, Jacob Marlin, Heather Barrett, Tom Pop, and Jaren Serano, attended the conference and presented on various topics. Dr. Marisa Tellez of the Crocodile Research Coalition also provided local perspective on conservation in Belize and several student presenters from southern Belize’s Independence Junior College highlighted research questions and projects pertaining to reptiles and amphibians in the country.    At the close of the conference, BFREE was given the Porras Conservation Award. This award is granted in recognition of lifelong achievements in and contributions to field biology. The award is presented to a speaker (or – in this case – an organization) who has demonstrated that their work represents exceptional accomplishments in the field that benefit herpetological conservation. We are pleased and honored to have our work recognized in this way.

Birds, Chocolate, Forests, and Allegheny College

BFREE’s Birds, Chocolate and Forests course provided students with a real life example of the complexities of conservation within the rainforests of southern Belize. Through interactive demonstrations and presentations, field research and experiments, day-excursions, conversations with all members of the BFREE team, and exploring the surrounding environment, students developed an understanding of the relationships not only between birds, chocolate, and forests, but people as well. The complicated web of relationships that exists among efforts to conserve biodiversity and livelihoods is something we speak often about in our Environmental Science and Sustainability courses at Allegheny College. In our introductory course for the major, we make it clear to students that you will not find the solutions to environmental problems in a book. Each problem is unique and requires individuals who can critically examine the issue to devise a unique and thoughtful solution. The 2-week experience with our BFREE guides was a perfect compliment to this concept. In a country where people rely on the natural resources of the surrounding forests to provide them with medicines, food, and fertile land for agriculture, it quickly became clear that you couldn’t simply tell people to stop using the forest. BFREE  provides a unique solution: conserve the forest and grow a cash crop within the understory in an effort to conserve birds and other organisms, as well as livelihood. Jacob spoke with us about ongoing efforts to ensure that methods of cacao agro-forestry were fully understood so that local farmers could create successful farms and provide for their families demonstrating that BFREE is thinking about the sustainability of their program. The complexities of conservation also became apparent when learning about the Hicatee turtle, talking with Ernesto about traditional Mayan culture, and spending time on the coast in Placencia. This course was the perfect compliment to what we are saying in the classroom:
solving environmental problems is complicated.

Students from Allegheny College spend time in the BFREE cacao nursery. The group received hands-on experience in what it takes to make chocolate, from seed – to bean – to bar!

In order to solve those complicated problems, one must be curious, flexible, and have excellent communication and intercultural skills. Many of our students had minimal experience traveling outside of the US and very few had been submerged in a culture different to their own. When students are outside of their comfort zone, they are forced to adapt and push their own limits. It is through experiencing this unknown, whether it be using compost toilets, learning to fall asleep to the sound of howler monkeys, or discovering just how difficult harvesting cacao in the jungle can be, students were forced to overcome new challenges. After reading their final journal entries, many of our students surprised themselves. They learned that they are capable of much more than they ever thought possible. Through conversations with the BFREE staff and local Belizeans we met during the trip, worldviews were expanded and communication skills improved. For many students, this was the highlight of the trip, getting to know individuals with completely different life experiences than themselves. From an educational perspective, this is impossible to teach in a classroom or while simply touring around. BFREE provided an excellent experience for students to be completely submerged in the Belize culture, all while learning in a completely new environment.

A pile of roasted cocoa beans lay on the table. These beans have a thin, papery shell around them which needs to be removed. The students are cracking the beans open and the shell is removed in a process called winnowing. The lighter shells are blown away with fans, leaving behind pieces of pure cocoa bean, known as “nibs”.

New Rearing Pond at the Hicatee Conservation & Research Center

Designed to study the reproductive biology and to determine if the Central American River turtle could be bred in captivity, the Hicatee Conservation & Research Center opened in 2014 and was met with immediate success when, in the summer of 2015, the first seven hatchlings emerged. This was followed by five hatchlings in 2016, 84 hatchlings in 2017, and 179 in 2018.

The extrusion welder was used to join hard plastic pond liner

The HCRC originally included two large breeding ponds, an overflow pond and several rearing tanks. The small rearing tanks at the center quickly reached capacity and HCRC staff identified an urgent need to provide the necessary space and improved environment for the 2018 hatchlings and the soon to arrive 2019 cohort. After much discussion, it was determined that converting the overflow pond into a large rearing pond for hatchlings and juveniles was the most cost effective and quickest solution to housing all the expected hatchlings now and in the foreseeable future.

We secured funding from Oklahoma City’s Zoo’s Care Grant Program and from Zoo New England to begin pond modifications. Additional support was provided through funding for supplies offered by Jacksonville Zoo and Gardens in 2018 and the purchase of a very important piece of machinery was made possible thanks to proceeds from the Turtle Survival Alliance’s 2018 fundraising auction.

Pond modification was slow to get underway due a very wet rainy season. However, during February and March construction took place and 140 turtles were placed in their new home in April. The rearing pond (Pond C) is forty-feet in diameter and approximately six-feet deep at the center. A six-foot perimeter fence will encircle the pond and fresh water is provided by solar powered pumps which were already in place at the facility. We will modify Pond C in the coming months to include a floating island and the planting of food trees and grasses as has been done in Ponds A and B. Our hope is that the facility will offer a healthy environment for all hatchlings produced at the HCRC until they are ready for release into the wild.  

Thanks to the Turtle Survival Alliance for their continued partnership on the Hicatee Conservation and Research Center. Thanks also to project sponsors: Oklahoma City Zoo, Zoo New England and Jacksonville Zoo and Gardens.

Team Hicatee Competes in La Ruta Maya

By Jaren Serano

The La Ruta Maya 2019 Belize River Challenge is considered one of the most gruesome races in Belizean history and it is the longest canoe race in Central America:  a four- day event covering over 180 miles of Belizean river. Paddlers from all corners of the country and internationally converge at the banks of the Macal River – the starting point of the race.

La Ruta Maya means “The route of the Mayans.”  This route was used by the ancient Maya for quicker access to the coast and, in the mid-1600s, by loggers to move logwood to the coast. On March 9, 1998, the La Ruta Maya was conceptualized by Richard Harrison of Big-H Enterprises when he launched a new brand of purified water. Since then, the race has evolved into an annual competition that brings together people from all over Belize and also raises consciousness about various environmental issues happening around the country.

Tom Pop, Scottie Trevino, and Rony Jimenez paddled for Team Hicatee during La Ruta Maya

This year BFREE decided to join in the action and partnered with Belize Wildlife Referral Clinic (BWRC) to create Team Hicatee. The primary reason for our participation was because this four-day river event is a major time when Hicatee turtles are harvested heavily for human consumption. We believed having a race canoe titled simply “Save the Hicatee” in this historic race  would be a strong message and a great platform to raise awareness for this critically-endangered species.

Team Hicatee consisted of three paddlers: Scottie Trevino, Rony Jimenez, and Thomas Pop of BFREE. Although this was Team Hicatee’s first time to compete together, they placed 31st overall and 3rd in their respective category (Mixed Category- one female and two males).

When asked about the race, Tom had the following to say: “It was tough and challenging but a very fun race. I did it for conservation to raise awareness for the Hicatee. If it wasn’t for them I wouldn’t travel that 180 miles.”

Team Hicatee placed 31st overall and 3rd in their category.

“This race is important because it helps locals to be more aware of the different conservation  issues around the country and it shines a light upon these issues.”

“Team Hicatee gave a challenge even though it was our first time, at the end of the day we were competitive. And I felt that my goal of raising awareness was completed because at the start of the race people didn’t even recognize us as competitors. But as the four days progressed we started hearing on-lookers yelling from the banks of the river “Go Hicatee Go!”  and that made me feel even more happy. They didn’t have to know who I was but the fact that they recognize our canoe and acknowledge that we were Team Hicatee made me feel like a proud conservationist.”

We at BFREE would like to extend a special thanks to Derric Chan of Friends of Conservation and Development (FCD), and Justin Ford, Belize Wildlife and Referral Clinic (BWRC), for their coordination and support of Team Hicatee.

Spring ’19 Hicatee Health Assessments

 

Team Hicatee Spring 2019

During the early March Hicatee Health Assessment, a total of 214 turtles were assessed at the Hicatee conservation and Research Center (HCRC). The primary purpose of the spring health assessment was to perform a basic exam of the overall health of the captive population at the HCRC. Because oviposition takes place between the months of November and February, it was also relevant to check for the presence of additional eggs. 

Prior to the Health Assessments beginning, a small team of volunteers arrived to help prepare the site. The team cleaned hatchling tanks and moved the 140 hatchlings from the 2018 cohort from the soft release cage where they had been housed since December. They were placed there during the coldest months of the year because the water in Pond A maintained higher temperatures than in the smaller, above-ground tanks where they live during warmer months. Hatchlings were counted and given a quick check before being transferred back to the tanks where they acclimated until their assessments a few days later.

The three day processing started off with adult turtles being netted from the pond A, then placed in their respective holding area awaiting assessment. On day two, Adult turtles from Pond B was then netted and assessed. Day 3 commenced with a scanning of both pond perimeters for nest cavities which showed signs of eggs. Followed by the assessment of hatchlings from the 2018 cohort. Results from this year’s spring health check are still under analysis.

Cayle Pearson and Sarah Cristoff of Jacksonville Zoo and Gardens isolated several adult male turtles to collect additional data that will help them troubleshoot issues relating to the Hicatee turtles held in captivity at their facility.

We were grateful to receive support and assistance from the following participants in our spring health check: Dr. Isabelle Paquet Durand, Veterinarian at Belize Wildlife and Referral Clinic, Cayle Pearson, Supervisor of Herpetology, Jacksonville Zoo and Gardens, and Sarah Cristoff, Veterinary Technician, Jacksonville Zoo and Gardens, Heather Alford, Missy Belmer, Laurie Haven, Doris Dimmitt, Rodney Dimmitt, Tim Gregory, and Emily Gregory. We would like to express our gratitude to Jacksonville Zoo and Gardens for their financial support for this spring’s Hicatee health assessment.

The Hicatee Conservation & Research Center is a joint protect between BFREE and Turtle Survival Alliance. The bi-annual Assessments help ensure the health of captive animals at the HCRC and also contribute to our ongoing research of these critically endangered turtles. #savethehicatee
