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.

Mark Canti began work for BFREE in January. In May he applied to the BFREE Science and Education Fellowship 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.

Lenardo has great interest in documenting wildlife. Some of his boa constrictor photos will be included in an upcoming scientific publication.

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!

August 18, 2021/0 Comments/in Conservation, Education, Hicatee Turtles, Non-profit, Research, Student, Turtle Conservation, Uncategorized /by Heather Barrett

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

August 18, 2021/0 Comments/in Conservation, Education, Fellows, Hicatee Turtles, Non-profit, Research, Student, Turtle Conservation, Uncategorized /by Heather Barrett

During the September 2020 Health Assessment wearing his Hicatee Hero cape

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.

TSA-NAFTRG Turtle Survey at BFREE

August 10, 2021/0 Comments/in Blog, Hicatee Turtles, Research, Turtle Conservation, Uncategorized /by Heather Barrett

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!

Spring Health Assessment 2020

April 2, 2020/0 Comments/in Blog, Conservation, Education, Hicatee Turtles, Non-Proft, Research, Turtle Conservation, Uncategorized /by Tyler Sanville

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!

What is World Migratory Bird Day:

World Migratory Bird Day in the Americas is coordinated by the organization, Environment for the Americas, which promotes bilingual educational materials and information about birds and bird conservation. Environment for the Americas celebrates the migration of nearly 350 bird species between their nesting habitats in North America and wintering grounds in Latin America, Mexico, and the Caribbean.

Now in its 26th year, World Migratory Bird Day (WMBD) has grown from a one-day event to hundreds of projects and programs year-round and encourage individuals and organizations to join them in selecting their own date to celebrate WMBD. BFREE has selected the entire month of March to celebrate WMBD in Belize and we invite you to join us!

We are inspired by the phase-out plan to ban single-use plastic in Belize that became effective on 15 January 2020. The Minister of Agriculture, Fisheries, Forestry, the Environment, Sustainable Development and Immigration, Hon. Goodwin Hulse, signed into law the Environmental Protection (Pollution from Plastics) Regulations, 2020 that is set to reduce plastic and styrofoam pollution through the phasing out of single-use plastics in Belize as a control measure to protect the terrestrial and marine environment from harmful plastic contamination.

With this in mind, we at BFREE are celebrating WMBD by embracing the message, “Protect birds: Be the solution to plastic pollution.”

We invite you, our partners country-wide to join BFREE in tackling the challenges of plastic pollution in the environment by sharing with your classrooms the many ways that plastic can harm birds and by offering some ideas for ways that we can reduce our use of plastic items.

The Truth Behind Plastic Pollution:

Since plastic was introduced in the 1950s, an estimated 8.3 billion metric tons have been created. Only about 9% of plastic materials are recycled, leaving more than 6.3 billion metric tons of plastics in landfills or polluting the environment. “One of the main types of debris in the marine environment today is plastic. We know fishing gear, plastic bags, bottle caps, utensils, and other plastic pieces are entangling and being ingested by birds. Plastics harm birds in marine environments, as well as other habitats. As human use of plastics grows, so too does the amount of plastic pollution that invades most ecosystems around the globe. “Plastic debris such as fishing line poses a serious risk of entangling birds, which can entrap them and cause serious injury,” says Dr. Susan Bonfield, Director of Environment for the Americas. Migratory birds also have a high risk of directly ingesting plastics. It’s been estimated that 80% of sea and shorebirds have consumed foam, pellets, thread, and other items. In addition, small bits of plastic, known as microplastics, pose a hazard to birds and smaller organisms throughout the food chain due to the toxins they concentrate in the environment.

The Spectacular Journey of Birds:

In addition to raising awareness about issues important to bird conservation, World Migratory Bird Day is also a celebration of the spectacular journeys that migratory birds take as they travel between nesting and non-breeding sites around the world. Global partners at the Convention on Migratory Species in Bonn, Germany recognize that “World Migratory Bird Day joins our voices as one for the protection of the birds we share. With raised awareness of threats such as plastic pollution to birds, it is our opportunity to take action by making changes that help birds, whether personal or more broadly.” Although WMBD is traditionally celebrated in Canada and the U.S. on the second Saturday in May, in reality every day is bird day, and programs, festivals, and other events occur throughout the year, whenever it works best for organizers—and the birds. “Ultimately, the goal of WMBD is to connect people to nature through birds,” says Miguel Matta, WMBD Coordinator in Latin America.

About BFREE:

The Belize Foundation for Research & Environmental Education (BFREE) operates a biological field station in the rainforest of southern Belize. Our mission is “to conserve the biodiversity and cultural heritage of Belize.” We strive to successfully integrate scientific research, environmental education, conservation, and create sustainable development opportunities for alternative livelihoods for Belizeans.

About Environment for the Americas:

WMBD in the Americas is coordinated by Environment for the Americas, which provides bilingual educational materials and information about birds and bird conservation throughout the Americas. Their programs inspire children and adults to get outdoors, learn about birds, and take part in their conservation. To learn more about migratory bird habitats, download WMBD educational and promotional materials in Spanish and English, and search for activities planned in your area, visit http://www.migratorybirdday.org/.

In Pursuit of Hicatee in Belize by Day Ligon

November 20, 2019/0 Comments/in Blog, Education, Hicatee Turtles, Research, Turtle Conservation /by Tyler Sanville

The Hicatee, as Dermatemys mawii is known in parts of its range, is truly a unique turtle.
Although fossil records indicate that closely related species once occurred across Central
America and Europe, Hicatee remain as the only living representatives of a formerly species-rich
family of turtles. It is a large turtle, sometimes exceeding 22 kilograms. Despite its large size, it
is streamlined and, thanks to huge webbed feet, is extremely fast in the water. On land, however,
Hicatee are out of their element. They struggle to elevate their heads against gravity, and even
short walks across dry ground may leave their shells abraded with small cuts and scuffs.
Historically, this large denizen of rivers, lagoons, and mangrove swamps was common in parts
of Guatemala, Belize, and southern Mexico. In many communities throughout its range, Hicatee
are culturally important, not just as a frequently seen and admired inhabitant of the rivers along
which many communities have been built, but also as a culinary delicacy that is sought after for
holiday feasts and other celebrations. Unfortunately, its popularity at the dinner table is likely the
single greatest factor that is driving population declines. Today, few populations remain in
Mexico or Guatemala, and even those in the relative stronghold of Belize have declined
precipitously in recent decades.

Just how much have Hicatee populations declined? Everyone with experience with the
species seems to agree that declines are alarmingly great, but it’s also hard to put a number on.
Excellent research has been conducted that has generated insights about the species ecology,
reproduction, distribution and relative abundance, but since the 1980s efforts have been
intermittent and seldom generated more than a qualitative assessments of population sizes or
demographics. This isn’t for lack of interest or effort; animals that have the capacity to move
long distances and occupy open systems such as rivers are extremely challenging to count!

Fortunately, technological and analytical advances have made the solutions to this
problem more attainable. In spring 2019, members of the Turtle Ecology Lab at Missouri State
University teamed up with partners at the Belize Foundation for Research and Environmental
Education (BFREE) to determine the feasibility of generating population estimates. In five
weeks of field work, 193 Hicatee in three different populations were captured, weighed,
measured, and permanently marked for future identification. Additionally, a subset of turtles in a
closed lagoon system were equipped with GPS tags and sonic transmitters that will produce
information about their movements. These data will be especially interesting as the rainy season
commences, the lagoon reconnects to the Belize River, and turtles have the option of either
staying within the lagoon or venturing out into flooded forest or even to the river. This
information about the movement patterns of Hicatee will be put to use in 2020 when mark-
recapture efforts will be conducted to generate some of the first precise population estimates for
the species. These estimates, when generated in open rivers, become much more accurate when
typical movement patterns are known and can be included in population models.

In addition to calculating the size of populations of Hicatee in both open and closed
populations, as well as in hunted and protected areas, work in 2020 will benefit in other ways
from the preliminary research conducted in 2019. For instance, growth rates in captivity are
known thanks to research conducted at BFREE. However, little is known of growth rates in the
wild; by recapturing turtles that were first measured in 2019, not only will calculating growth rates across a range of size classes be possible, but so too will assessing the sexual maturity of
the many subadult turtles that were captured provide information about size at maturity.

All of this information is but a drop in the bucket in comparison to what remains to be
discovered about the fascinating Hicatee, but every new piece of life history data can help to
inform conservation efforts on the species’ behalf. And of course, field research efforts such as
were undertaken in 2019 require a tremendous network of support. Participants from the Turtle
Ecology Lab at Missouri State University included Denise Thompson, Donald McKnight
(currently at James Cook University), and Ethan Hollender. Thomas Pop and Jaren Serano joined
the effort from BFREE with tremendous support from Jacob Marlin and Heather Barrett. Elyse
Ellsworth from the Siler Lab at University of Oklahoma and Hunter Howell from University of
Miami also put in many long hours in the field. Yamira Novelo (Wildlife Conservation Society)
helped both in the field and with some logistics. Albert Gill lent his assistance and knowledge of
the area during work at Spanish Creek. Additional assistance was provided by Felicia Cruz and
Gilberto Young in the Belize Fisheries Department, Jeff Robison and Roberto Flores at Yalbac
Ranch, and Alan Jeal at Gallon Jug Ranch. Finally, this conservation project would have gone
nowhere without assistance from Bart Harmsen and valuable advice from Thomas Rainwater and
John Polisar. Reversing the population declines Hicatee have experienced will require a
community effort, and work thus far has proved that a dedicated network of people with a
passion for saving this charismatic but critically endangered species already exists and is already
working toward this goal.

Spring ’19 Hicatee Health Assessments

September 23, 2019/0 Comments/in Blog, Eco-Tourism, Research, Turtle Conservation /by Tyler Sanville

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
