TSA-NAFTRG Turtle Survey at BFREE

/0 Comments/in , , , , /by

Last month, the BFREE reserve became the focus of a mark-recapture survey by the Turtle Survival Alliance’s – North American Freshwater Turtle Research Group (TSA-NAFTRG).  After a year’s delay due to the COVID pandemic, the team was thrilled to get approval from Belize Fisheries Department to implement their research.

The TSA-NAFTRG team’s goals included establishing safe protocols for surveying freshwater turtles on the property, training BFREE staff on those methods, locating appropriate long-term survey sites and completing an initial assessment. Their timing couldn’t have been better: with the onset of rainy season, creeks were flowing, puddles formed regularly and turtles were everywhere.

The TSA-NAFTRG team of Eric Munscher, Arron Tuggle, Andy Weber, Collin McAvinchey, and J. Brian Hauge  were joined by BFREE staff, Tom Pop, and Jonathan Dubon as well as BFREE Fellowship Program Alum, Jaren Serano, who helped with the survey just prior to returning to the U.S. for grad school. TSA COO, Andrew Walde, and TSA Board Member/ WCS Coordinator for Turtle Conservation, Brian Horne, were also present and able to spend time in the field during the survey.

This initial assessment was deemed an incredible success with 227 turtles captured, marked, measured and safely released. Turtles found included Meso-American Slider, White-lipped Mud Turtle, Tabasco Mud Turtle, Scorpion Mud Turtle, Mexican Giant Musk Turtle, Central American Snapping Turtle, and the Furrowed Wood Turtle – representing seven of Belize’s nine freshwater turtles. (Fun fact: the Central American River turtle/ Hicatee is the only Belizean freshwater turtle that does not naturally occur on the BFREE reserve!)

We are grateful to the TSA-NAFTRG team for supplying us with the expertise and field equipment needed to ensure this survey continues and we look forward to their return trip next July!

March 2021 Hicatee Health Assessment

/0 Comments/in , , /by

Over the last six years, the Hicatee Conservation and Research Center (HCRC) population of critically endangered Central American River Turtles, Dermatemys mawii, has grown from the 22 founding adults and subadults to 45 breeding adults. Sixty-four clutches of eggs have been deposited from 23 reproductive females resulting in 693 eggs, and over 650 hatchlings. The total current captive population at the HCRC is 345 individuals. Of them, 282 turtles representing 4 cohorts (2017, 2018, 2019, 2020) have been identified for release.

The 2020/2021 egg laying season is almost complete, and in addition to the numbers mentioned above,  we have added 15 clutches totaling almost 150 eggs so far. Our success in breeding and hatching large numbers of D. mawii has provided extensive morphometric data on hatchlings, determined best practices for reliably reproducing the species in captivity, and pushed us towards advancing the next phase of the project which is reintroduction of head-started animals back to their historic range. As part of that initiative, surveys of various rivers were initiated in 2019, and continued in 2020, to help identify potential release sites. In preparation for releases, disease testing of animals raised in captivity is a priority to ensure that they do not pose a health risk to existing wild D. mawii populations.

The Value of Health Assessments

Both individual and population level health screening are important considerations for these programs to ensure that the individuals selected for release are healthy and fit to increase their likelihood of survival post-release, as well as do not pose a health risk to remnant wild populations. Health assessment and pathogen screening also provide baseline data and a reference point for understanding disease ecology in captive and free-ranging animal populations.

With all this in mind, our spring 2021 Hicatee Health Assessment was geared toward sampling a subset of captive turtles in different age classes to collect samples for later diagnosis specifically looking for pathogens. The HCRC Manager, Thomas Pop, along with HCRC Assistant and Wildlife Fellow, Jonathan Dubon, implemented the health assessment with the support of Jacob Marlin and Heather Barrett.

Prior to our Health Assessment at the HCRC, the team joined up with Day Ligon and Denise Thompson in Central Belize to collect samples from a group of wild individuals to provide a reference and for comparison. All samples were collected under a permit provided by the Belize Fisheries department. Samples will be exported from Belize to the USA, and will be analyzed in a lab in the Wildlife Conservation Society Molecular Laboratory at the Bronx Zoo in New York.

Dry Season at the Turtle Ponds by Jonathan Dubon

/0 Comments/in , /by
HCRC Manager, Tom Pop and Wildlife Fellow, Jonathan Dubon hold eggs they collected from the Hicatee ponds.

As the dry season rapidly approaches, we at the HCRC have a lot of work on our hands to keep our program running at its best. We have several mini-projects currently being conducted, such as improving the husbandry, daily maintenance of the site, taking care of about 400 critically endangered Hicatee turtles, and managing 100+ eggs (so far this year)!  We also spend our time brainstorming ways to improve water quality to help our turtles live healthy and happy. One of the ideas we are implementing is improving solar energy to pump more freshwater into the ponds by building a solar tower. We have dug and constructed the foundation for the tower, and in the coming weeks, we plan to finish constructing the braces and the tower itself.  


Nesting Season

A clutch of eggs collected during the 2020-2021 nesting season.

The nesting season began in early November 2020, and we have since collected 12 clutches of eggs or 108 total eggs. We recently discovered the 13th clutch; however, we will not collect it yet and are conducting a natural hatchment experiment on it first. We are unsure how many eggs are in this clutch, but I estimate anywhere between 7-11. Tom Pop, HCRC Manager, and I have also found three old clutches of eggs from last season which may not have been fertile. Adding up every clutch, our grand total is nearly 1,000 Hicatee eggs laid at our breeding facility!

Wildlife at the Turtle Ponds

Working at the HCRC in the middle of the jungle has its many benefits. Not only do we get to see cute and adorable Hicatee turtles every day (yes, we all think they are adorable), we also see other exciting wildlife.  Most common are green iguanas, pond sliders, the great curassow, crested guan, cat-eyed snakes, and speckled racers. Tom and I were recently pruning the fig trees around the turtle ponds when we heard some familiar birds in the trees not too far from us. We listened as we continued our work, and the calls were getting louder and louder. As we looked up, we saw a huge flock of beautiful and magnificent Scarlet macaws that had flown directly above us. We immediately looked up and started counting at least 20 macaws perched above the turtle ponds, so close we could see them clearly, even without binoculars. If you thought it couldn’t get better, it does! A few months ago, I witnessed my first wild Harpy eagle perched on a tree in the cacao farm just a few meters from the HCRC.  An amazing lifer, right!? 


It will be a full year since I started my fellowship position at BFREE this June. I’ve enjoyed witnessing all of the seasonal changes, the wildlife, and the opportunity to learn more about the Hicatee turtle.

By Ms. Ornella Cadle, Hicatee Awareness Month Committee Coordinator

Proud Hicatee Heroes show off the coloring sheet and board game included in this year’s educational materials. 

Each October, BFREE ambassadors and partners visit schools to present on Hicatee Awareness Month. Due to the COVID-19 Pandemic, outreach looked a bit different this year. While traveling to various schools for outreach wasn’t a safe option, we wanted to ensure the incredible resources still reached students’ hands across the country. BFREE emailed electronic resources directly to over 400 principals and teachers in Belize. The following schools in the Cayo, Stann Creek, and Toledo Districts received resource packets reaching nearly 500 students in their classrooms. 

  • Church of Christ Primary School, Independence Village, Stann Creek District
  • Moriah Learning Center, Independence Village, Stann Creek District
  • Shiloh Seventh-Day Adventist School, Independence Village, Stann Creek District
  • Golden Stream Government School, Golden Stream Village, Toledo District
  • Belize Rural Primary School, Rancho Dolores Village, Cayo District

A dedicated committee of volunteers and BFREE staff members created this year’s resource materials. The committee met for several months to build a packet of creative, engaging, and informative educational resources.

A highlight of the materials included; 

  • Coloring sheet of the Hicatee Hero mascot
  • “Hicatee and Ladder Migration Game,” displaying different predators for the hicatee that you must pass by answering true and false questions correctly.
  • “Mr. Hicatee” sing-along video featuring a conversation between Mr. Hicatee and a man named Damien who wants to learn more about the problems that Mr. Hicatee encounters in his daily life and how he can help.
View all Hicatee Educational Materials
Educators from Moriah Learning Center, Shiloh Seventh-Day Adventist School, and Church of Christ Primary School hold the Hicatee conservation educational materials delivered to them for their classrooms. 

Various news sources including, Breaking Belize News, The Reporter Newspaper, Cayo Scoop, and Heritage Education Network Belize, have featured Hicatee Awareness Month materials throughout the month. Hicatee Awareness Month Planning Committee Coordinator Nelly Cadle says, “I am very proud to be the Committee Coordinator and work with such a talented group of people. I truly believe that our hard work has paid off and that we could reach a lot of young students. However, our job is not done, we still have more work to do to save the Hicatee, and I look forward to continuing our efforts to conserve this national treasure of Belize!” 

We would like to say a special thank you to our friends – the Hicatee Heroes at Santa Fe College’s Teaching Zoo in Gainesville, Florida. Their Quarters for Conservation project helped fund the production of all materials for this year’s Hicatee Awareness Month.

Introducing Jonathan Dubon, BFREE Science & Education Fellow

/0 Comments/in , , , , , , , , /by
Jonathan Dubon, BFREE Science & Education Fellow

BFREE is pleased to introduce our newest Science & Education Fellow, Jonathan Dubon. Jonathan grew up in Independence Village about 20 miles east of BFREE and has known from an early age that he wanted a career that would include his passions for field experience and outdoor adventures. This passion grows from visiting his Grandma’s farm near Punta Gorda as a child where he has many fond memories of exploring her land and being exposed to nature. Because of this childhood experience and influence from his brother who is also involved in conservation, Jonathan went on to study Natural Resource Management at Independence Junior College. He graduated with his Associate’s Degree in June 2019 and with the highest honors in his department.

Jonathan’s first visit to BFREE was on a school field trip with Independence Junior College in February 2019. Jonathan says, “I fell in love with the place and it’s environment – at that very moment I knew I wanted to come back. I like everything about being at BFREE including the friendly staff, the environment, everything is just very welcoming. This is exactly where I imagine my dream job.” He returned one year later as a volunteer in the Spring 2020 Hicatee Health Assessments where he assisted in the 5-day health check.

Now, in the second week of his fellowship, Jonathan shares, “It’s so exciting to be here at BFREE right now. I only know a little bit about the biology of Hicatee Turtles and I am overly excited that every day I now get to learn something new about them. It is thrilling to work with the hatchlings; I am also eager to learn about all the other animals found here at BFREE such as birds, snakes, and mammals. I also really enjoy hearing the birds singing early in the morning while working by the pond. “

Jonathan says, “my message to all Belizeans is that the Hicatee are especially important to our ecosystem, and it is critical that we protect them – Belize has the honor of being the final stronghold for these turtles, who are the last in their lineage. “

We are thankful to the Turtle Survival Alliance for their funding of the BFREE Science and Education Fellowship. This is the second fellowship funded by the TSA; the first was awarded to Jaren Serano who served as the BFREE Science and Education Fellow from January 2018 – December 2019. The Science and Education Fellowship is assigned to support the operations in one of three areas at BFREE – the Hicatee Conservation & Research Center, the cacao agroforestry project or the protected areas program. It is a two-year immersive work training opportunity for recent Belizean junior college and college graduates who exhibit leadership potential combined with a clear interest in the conservation of the country’s natural resources

Right: Pond A looks sparkling clean after two weeks of cleaning took place at the HCRC.

For the past two weeks, Tom Pop and Jaren Serano have had the challenging yet important task of cleaning each of the three turtle ponds at the Hicatee Conservation and Research Center. With large, deep, muddy pools, the work is labor-intensive but critical to the health of the nearly four hundred Hicatee turtles in residence here.

The ponds were tackled one at a time starting with Pond A. This pond is dedicated to Breeding adults, so all turtles had to be caught and placed in holding tanks where they stayed throughout the cleaning process. Additionally, other wildlife like swamp eels and red-eared slider turtles and some larger fish like Tuba were also caught and placed in nearby creeks. 

Jacob Marlin and “Mustang.”

The actual cleaning process involved using a Honda Trash Pump (fondly referred to as “Mustang” due to its amazing strength and speed) to remove huge volumes of water as well as leaves and muck that had been gathering at the bottom of the ponds over the past few years. This has been followed by filling the ponds with fresh water to rinse the pond liner and dilute the thick muck, and then, once again,  using the trash pump to remove more diluted muck and dirty water. This cycle repeats until the water in the ponds is clear and there is little to no detritus remaining at the bottom. Each pond has taken about seven days of hard labor. 

With Ponds A and B complete as of May 17, the team has started on the rearing pond. The first task has been to lower the water to about two feet in the center in order to catch the over 200 juveniles living there. The “muck” which includes turtle manure is drained into an area outside the fenced area of the HCRC. The material gathered there will rest and break down before being relocated and used as compost for trees in our cacao agroforest.

Belize Wildlife and Referral Clinic Spotlight

/0 Comments/in , , , , , , , /by
Dr. Isabelle examines each 2019 hatched Hicatee before placing it in the bin to travel back to the HCRC.

Last week, BFREE Deputy Director, Heather Barrett, traveled to the Belize Wildlife and Referral Clinic (BWRC) in the Cayo District of Western Belize to retrieve twelve of the HCRC captive-born Hicatee turtles. They had been cared for at the BWRC by Dr. Isabelle Paquet-Durand, DVM, and her team and the turtles were in good health overall. While they could have stayed for longer observation and data collection on this unique species, Corona changed it all. The recent shutdown of tourism, which provided a large portion of the non-profit clinics income as well as hands-on assistance from interns was combined with being an essential business that continued to offer services. Then came the spread of dry season fires throughout Belize and the annual baby season (which is high season for wildlife orphan intakes)… and “anybody healthy had to make space for more critical cases”. Just like the human hospitals had to do for COVID patients, Dr. Isabelle, therefore, requested BFREE to retrieve our turtles to make room for those animals with more serious health conditions. 

Injuries to wildlife during a fire may include burns, injuries from falling out of trees, or having things fall onto them while escaping, or maybe less severe stresses that can still prove fatal if not addressed – like smoke inhalation and dehydration. Some animals just need access to water, food, or shelter, until their natural environment recovers. The BWRC received animals with all of these conditions. On the day that the Hicatee were retrieved, there were kinkajous, turtles, a howler monkey, squirrels, opossums, and snakes – escapees from the fire or orphans for unknown reasons. One kinkajou had fled the fire with minor burns only to climb an electrical pole where it grabbed a live wire and was electrocuted. 

The BWRC’s mission is to support wildlife conservation efforts; domestic animal health and welfare; and the veterinary profession in Belize through medical services, education, research, and collaboration. Their work is big and growing all the time but they try to stay focused on their mission. In addition to the fire victims in the clinic last week, there were also confiscated animals and animals that were neglected or abused by their owners. 

Jacob Marlin first met Dr. Isabelle in 2011 when the Hicatee Conservation Network was being formed and she first visited BFREE and the Hicatee Conservation and Research Center in 2015. Because of her valuable insight and a keen interest in helping to conserve this amazing species, she was invited back to participate in all subsequent Hicatee Health Assessments and has been a strong partner ever since.

Dr. Isabelle has been the lead Belize veterinarian evaluating our captive population of Hicatee for over four years. She attends two Hicatee Health Assessments per year to determine the health and reproductive status of our growing population of turtles. Just like baby humans, our hatchling and juvenile turtles are especially vulnerable to sickness caused by temperature changes, nutritional deficiencies, or other stressors. For this reason, when our young turtles are failing to thrive, Dr. Isabelle takes them to the clinic for several months to give them the additional veterinary care that will help them recover. This also gives her the opportunity to monitor them in order to gain a better understanding of their needs over time.

In the four years that BFREE has partnered with the BWRC, we have been impressed by their commitment to wildlife like the Hicatee and to educating Belizeans and visitors from abroad. As their partner, we would like to advocate for their campaign to fundraise for operational expenses during this trying time.  With the halt of all veterinary trainees from abroad due to travel restrictions from Covid-19, the BWRC has lost a critical revenue stream. Like many organizations in Belize and worldwide, they are struggling to make ends meet but don’t want to furlough any of their small but critical staff when animals are still in need of daily care.

BWRC is thankful for any and all kind words, supplies or donations via PayPal to payment@belizewildlifeclinic.org.

Spring Health Assessment 2020

/0 Comments/in , , , , , , , /by

Between February 28th and March 1st, a total of 341 turtles (45 adults in the breeding population and 296 captive hatched animals) 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, to look for follicles and eggs in breeding-size females and to PIT-tag animals.

Ultimately, we would like all turtles at the HCRC to be identified using a scute notching system and also a Passive Integrated Transponder (PIT) tag. A PIT tag is a small radio transponder that contains a specific code, which allows individual turtles to be assigned a unique 10 or 15 digit alphanumeric identification number. Unlike acoustic tags that actively send out a signal, they are “passive” and do not require a battery. Rather than the tag transmitting a signal, the tag scanner (or reader) sends out a radio frequency and when a tag is within range, it will relay the identification code back to the receiver. The lack of a battery is the greatest advantage of the PIT tag since it allows for the production of much smaller tags that can be used on smaller organisms, which should last the life of the turtle. 

As in past assessments, two days were dedicated to measuring, giving health checks and ultrasounds to adult and subadult turtles. A day and half was dedicated to PIT-tagging all of the captive born turtles in the 2018 cohort as well as the ones from the 2017 cohort that had yet to be tagged.  

We were thrilled to have a great group of return volunteers from last year’s spring assessment, as well as new participants from Jacksonville Zoo, Belize Wildlife and Referral Clinic, and recent graduates of Independence Junior College in Belize. The team worked tirelessly over three days to ensure that every turtle received the attention it needed.

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 (BWRC); Glendy Delcid, BWRC; Cayle Pearson, Supervisor of Herpetology, Jacksonville Zoo and Gardens; Meredith Persky, Veterinarian, Jacksonville Zoo and Gardens; return volunteers, Doris Dimmitt, Rodney Dimmitt, Tim Gregory, and Emily Gregory; and new volunteers, Jesse Rope, Jonathan Dubon and Ajay Williams 

We would like to express our gratitude to Jacksonville Zoo and Gardens for their continued financial support spring health assessments at the HCRC and to the Turtle Survival Alliance for supplying the PIT tags and associated equipment. Finally, a special thanks is in order to Doris and Rod Dimmitt for supplying Tom Pop with new waders to keep him warm and safe from leeches!
