Tech Teaching Tools

Posted on | by Matthew Humphrey

by Nicole Thomas, GSTC Education Program Manager

As the Georgia Sea Turtle Center (GSTC) closes out its 15th anniversary year of education, rehabilitation, and research, the staff is looking forward in 2023. One of the Center’s goals this year is advancing ocean literacy through STEAM (Science, Technology, Engineering, Art, & Math) education. Understanding how the ocean supports and connects all life is vitally important to how decisions are made. The functions of the ocean impact what consumers buy, where they live, and what they eat. Pairing knowledge and awareness about the scientific processes of the ocean with creative problem-solving and solution-driven modifications are foundational pieces to the puzzle of sea turtle conservation.

How are these connections made? It usually begins in the classroom on a school field trip. The GSTC’s educational programs are designed as introductions to STEAM concepts and how humans can all play a role as ocean stewards. In the classroom, a variety of teaching methods are utilized like hands-on exercises and inquiry-based group work.

But STEAM isn’t just for students. One tech tool GSTC educators utilize for almost every school group is the interactive whiteboard. The whiteboard allows educators and students to work collaboratively, maintaining a higher level of engagement. Teachers can pull up models and data, interact with maps, and play videos. Using technology like e-boards is one of the ways GSTC staff can make a big impact in the short amount of time spent with students during their visit.     

Not every class has the funds or flexibility to visit the GSTC in person, but with STEAM education, learning can happen beyond the entrance doors. Second through twelve grade and college students can visit the Center through Virtual Field Trips covering a variety of topics like threats, veterinary medicine, habitats, and adaptations. These online programs provide an up-close view of the science and engineering that goes into rescue and rehabilitation.

Ensuring state-of-the-art teaching tools are available makes the Georgia Sea Turtle Center’s educational programs unique, providing the opportunity to reach thousands of students each year. The Jekyll Island Foundation’s funding support of the Center’s education mission helps bring STEAM to life. To help support the Georgia Sea Turtle Center, click HERE.

Sea Turtles Breaking Records

Posted on | by Matthew Humphrey

By Davide Zailo, Research Program Manager, Georgia Sea Turtle Center

The start of nesting sea-turtle activity began early this year on Jekyll Island. On April 28th, the Georgia Sea Turtle Center’s (GSTC) sea turtle patrol team was notified of mysterious large tracks spotted above the high tide line on Jekyll’s south end. Normally, the team begin its surveys for nesting sea turtles in May. Staff loaded equipment into the beach-ready UTVs, a necessary purchase made possible through funding provided by the Jekyll Island Foundation, and headed to the scene. Indeed, there were tracks left from the flippers and shell of an adult loggerhead sea turtle that had emerged around high tide the night before. She did not nest during this attempt, and it was characterized as a “false crawl”; however, it was a sign of an impending busy nesting season. In fact, Jekyll Island had the earliest recorded 2022 sea turtle nesting season activity for the entire state of Georgia.

From May to the end of October (or until the last known nests have hatched in Georgia), the GSTC Research Team, permitted by GDNR, patrols Jekyll Island’s beaches throughout the night to encounter as many nesting loggerhead sea turtles as possible. These night patrols allow the team to study females directly, collect nest data, and provide unforgettable experiences for guests attending nighttime Education programs. To ensure that nesting is not interrupted, researchers carefully watch emerging turtles from a distance until they start to lay eggs or begin returning to the water in the case of a “false crawl” to begin performing data collection. Every turtle is safely examined, measured, tagged, and have a skin collection taken for genetic analysis according to a flow-chart of data collection priorities. If a sample is not able to be safely collected we will wait and hope to encounter the animal again later in the season.

Each morning at 6 a.m., our Night Patrol team is replaced by a smaller Dawn Patrol team which covers Jekyll’s beaches to perform a daily check of each nest to document its progress throughout incubation and ensure it remains safe from unnecessary predation risk from species such as raccoons and foxes. Five days after hatching, the nest is carefully excavated to assess egg hatching success and collect other information.

The most common nesting sea turtle species, the loggerhead sea turtle (Caretta caretta), can weigh upwards of 300 pounds and lay up to multiple clutches, or nests, of 100+ eggs in a single season. Some turtles will place all their nests on Jekyll Island whereas others will distribute them among multiple islands. Nesting females are at least 30-35 years old and are the drivers of population growth, recovery, and ultimately, persistence. Tallying nests allows researchers to estimate numbers of adult females and whether the loggerhead population is increasing, stable, or declining. This year turned out to be a record-breaking year here on Jekyll, throughout Georgia, and the rest of the southeastern United States. A potential indication that the rewards of conservation and management activities such as protection of nesting sites and reductions in capture and mortality of sea turtles by commercial fishing vessels 30+ years ago are finally becoming apparent. On Jekyll, the island recorded 234 sea turtle nests which produced 21,624 hatchlings. For comparison, in 2004, only 25 nests were counted on Jekyll’s beaches.

These efforts would not be possible without the generous support of the Jekyll Island Foundation and its donors, supporting the native wildlife and building towards a more sustainable future.

Meet Our Donors: Mike & Joy Cook

Posted on | by Matthew Humphrey

Mike and Joy Cook joke that they “almost” don’t want to tell anyone how special Jekyll Island is.

“That lets the secret out,” they said, smiling in unison.

As the now former educators—she a librarian, he a teacher—were contemplating where to sunset after their careers, Joy read something about the Georgia Sea Turtle Center (GSTC), which prompted their first visit to the Island.

“We wanted to do something in retirement that helped animals and the environment,” she said.

Jekyll’s beauty made an indelible impression on these beach-loving Florida transplants and protecting it is especially important to them. “We’re from Miami…and saw what happened there with the skyline covered in skyscrapers,” Mike said.

“Here the moss-covered trees are our skyscrapers,” said Joy, “and even the gas station blends into the landscape.”

Once they bought a house on Jekyll and settled in, they got busy volunteering. “Let me put it this way,” teased Mike, “we’re DINKs (dual income no kids) with cats.” They signed up for a class on how to get involved and found out the GSTC had a virtual education program for youth, which they then supported for several years. They also got to know the park ranger and helped with some of nature programs such as Gatorology, the history, biology and conservation efforts related to the American Alligator, and Ranger Walks, a bald eagle nest viewing tour.

These days, in addition to any volunteer activities, they can often be found contributing to the Golden Isle’s edutainment through their Native American flute performances.

“We’ve been playing for about 20 years,” said Mike. “Before that, I’d never played an instrument.” It was a trip out west that first introduced them to the unique musical genre. They started to build a CD collection at their previous home in Florida, went to a dedicated school for the instrument in North Carolina, and eventually brought their talents with them to the Georgia coast.

“We like to share the idea of the flute circle, which is to help one another,” said Joy, speaking about their opportunities to perform for people on and off the Island.

That esprit de corps is also on display several times a week while they lead a class for practitioners of Qigong, an exercise flow of coordinated body-posturing along with breathing and meditation that supports health and spirituality.

When asked what they hope for Jekyll’s future, both agree that striking the right balance between what humans want and the environment needs has to be an ongoing commitment.

“The (Jekyll Island) Foundation does a good job [assisting with funding for] restoration projects in the Historic District and around the Island, [that help to] keep things preserved,” said Mike.

When ‘selling’ Island visits to family and friends, they make sure to mention how “laid back and comfortable” the atmosphere is, how the beaches aren’t as crowded as some of the other coastal destinations, and, of course, all the attractions—the GSTC, Mosaic, Jekyll Island Museum, the great restaurants, fishing off the pier, Driftwood Beach (“a must see”), Horton Pond—as well as the trolley tours.

“Even as residents we love to go on the trolley tours,” said Joy. “Depending on the time of year, there’s always something new to learn about the Island.”

They are especially fond of the Christmas holidays. “The Island events are a lot of fun,” Mike said. “We’ve decorated the (golf) cart and driven in the parade around the Island looking at all the light displays.”

For Joy, the best light displays Jekyll has to offer come twice a day. “A dawn and at dusk,” she offers, “the colors of the sky are just breathtaking.”

Crawling into Nesting Season

Posted on | by Matthew Humphrey

With May 1st marking the official start of turtle nesting season along the Georgia coast, the Georgia Sea Turtle Center (GSTC) is already busy patrolling Jekyll Island’s causeway for diamondback terrapins and beaches for nesting sea turtles.

DIAMONDBACK TERRAPINS

The GSTC and Jekyll Island Foundation (JIF) donors have partnered for nearly 10 years in diamondback terrapin rescue, research, and implementation of various protection methods during nesting season. These efforts focus on decreasing terrapin road mortality rates. The GSTC’s diamondback terrapin patrol team routinely drive the causeway in search of nesting mamas crossing the road and inspecting nest boxes for similar signs. Recently, JIF and ANIMEX, a new partner, donated fencing materials that were installed on either side of the entrance to Jekyll’s causeway, adding one more component used to help decrease terrapin roadway mortality rates.

SEA TURTLES

And along the beaches these ancient reptiles emerge from the ocean to begin nesting as early as May. Fertile turtles crawl slowly to the dunes, enter a trance as their eggs drop into the sand, laying over 100 ping-pong ball-like eggs under the cover of darkness. Then, the GSTC Sea Turtle Patrol Team jumps into action gathering measurements, identification information, and ensuring the nest is protected from predators and human disturbances. The data collected helps inform local, regional, and international conservation efforts.

Jekyll Island visitors hoping to catch a glimpse of this once-in-a-lifetime experience can join GSTC educators under the stars by registering for an Evening Turtle Walk or Ride with Night Patrol on select nights in June and July. There’s no guarantee a nesting turtle will appear, but the evening promises to make the night memorable!

The GSTC hospital and patrol teams continue to work diligently to rescue and rehabilitate these gentler creatures. Investments of any size are welcome and appreciate. GIVE NOW.

This year, 2022, marks the 75th anniversary of the establishment of Jekyll Island State Park. And yet, many visitors to Jekyll Island never know that this unique place contains more than just the Island itself. In fact, by the time one slows to make the turn from Highway 17 onto the Downing Musgrove Causeway, they have already crossed into its welcoming boundaries. The six miles of causeway to follow offers expansive views across nearly 7,000 acres of tidal marshlands brimming with biological diversity and dotted with forested marsh hammock isle-lets, all of which lies within the Park’s boundary. This lesser-known side of Jekyll Island, known as the “back-barrier marshes” covers more area than the Island itself and supports over half of the Wildlife Priority Species identified in the Jekyll Island Conservation Plan.

Like its State Park boundary, the work of the Jekyll Island Foundation doesn’t stop at the foot of the bridge onto the Island. The Jekyll Island Conservation Plan sets forth the following management priorities for the Causeway and back-barrier marshes:

  1. Minimize vehicle strike mortality of Wildlife Priority Species
  2. Reduce immigration of exotic-invasive plants and animals
  3. Prevent loss of elevation due to erosion or compaction of soils surrounding the Causeway
  4. Promote habitat diversity
  5. Maintain a safe and enjoyable experience for drivers and cyclists that affords opportunities to appreciate the natural beauty and abundance of wildlife evident upon arriving

The excellent work spearheaded by the Georgia Sea Turtle Center to better understand and protect Diamondback Terrapins along the Causeway is a shining example for how Foundation dollars can make a difference towards achieving these goals. Another For the Record piece this month highlights the latest big step in efforts to help terrapins avoid roadway hazards. And coming soon, thanks to generous donor support through the Foundation, the Jekyll Island Authority will be able to add a mile of new native wildflower meadow along the east end of the Causeway, making arrival to the Island even more welcoming, not just for human visitors, but for pollinating bees and butterflies as well.

The Causeway and back-barrier marshes are a truly special part of the Jekyll Island experience that connects the Island with the broader community of Brunswick and the Golden Isles, mutually strengthening the well-being of many. The next time you turn onto the Jekyll Island Causeway, take your time, breath in the fresh air, brake for terrapins, and think about giving to the Jekyll Island Foundation. Your contributions go a long way towards empowering better stewardship of every corner of Jekyll Island State Park.   

Providing for Wildlife at Horton Pond

Posted on | by Matthew Humphrey

by Yank Moore, JIA Natural Resources Manager

Horton Pond has become a destination for many guests and their families while visiting Jekyll. The wildlife viewing area, basking platform, and nature trail funded by the Jekyll Island Foundation allows visitors a chance to experience the American Alligator, Night Herons, Wood Ducks, and various other wildlife in their natural habitat. The JIA Conservation team’s goal for this project has been to provide a space for people to enjoy nature while improving habitat value for wildlife, increase educational opportunities, and encourage guests to become better stewards of the environment.

Beyond what is visible to the public, the JIA’s Conservation Department manages Horton Pond to be as productive and natural as possible without using harsh chemicals or other invasive means of control. Instead, sterile grass carp were introduced to eat the underwater aquatic plants that would normally take herbicide to control, and a recently installed solar aeration system to supply much needed oxygen for fish and other underwater wildlife to flourish.

Recently another upgrade was made to the pond. Funded by generous donors of the Jekyll Island Foundation, a solar aeration system was installed to not only provide oxygen, but enhance water quality, limit excess nutrients, and keep algae from causing issues for wildlife. Horton Pond is man-made and has no natural water input like a stream or river so it must rely on surface runoff and groundwater. Without management this pond could suffer from a stagnation effect and without the aeration system the pond could go through cycles of bad health. The system installed at Horton Pond is powered completely by a solar panel harnessing the power of the sun and is efficient enough with timers and controls to run even on cloudy days.

To see the system in action, visit Horton Pond early in the mornings when aeration system is on and when the pond needs it the most.

Shorebirds

Posted on | by Matthew Humphrey

By Ben Carswell, JIA Director of Conservation and Sustainability

The partnership between the Jekyll Island Authority, Georgia Audubon, Georgia Sea Grant, and Jekyll Island Foundation to support a State Sea Grant Fellowship based on Jekyll Island in 2020 and 2021 has ended following a productive and enriching year for Sergio Sabat-Bonilla. While Sergio has moved on to Ph.D. studies at Virginia Tech, thanks to his efforts, we now have a more complete understanding than ever before of how, when, and where shorebirds are using Jekyll Island’s beaches.

During his fellowship, Sergio logged countless hours surveying all of Jekyll’s beaches by bike and on foot, counting and identifying over 18-thousand individual birds representing 16 different species. Sergio found that the best time and place to see the greatest abundance of shorebirds while on island, is in the morning on the south end as the tide is rising but not yet high.

Another aspect of Sergio’s fellowship was to analyze four priority species – Wilson’s plover, piping plover, red knot, and American oystercatcher. Areas of research focused on where these species were most likely to be seen, at what stage of the tide, and at what time of day.

Piping plovers, a species that winters on Jekyll Island and is federally protected under the Endangered Species Act, were notably wider ranging along the beaches than had previously been assumed. Pipers, as they are affectionately called, and their cousins, the Wilson’s plover, utilize both Jekyll’s remote and less traveled beaches on the far south end of the island as well as the busier beaches fronting the island’s bustling Beach Village and Great Dunes Beach Park.

While it’s encouraging that these species are still finding space and food to support their needs even on Jekyll’s busiest beaches, it’s also cause for caution and awareness. As Jekyll Island has experienced increased visitation due to changing patterns of tourism during the pandemic, it is all the more essential for Jekyll Island conservation staff to continue to protect the wildlife habitat value of both Jekyll’s most pristine beaches as well as its most visited ones.

How can you participate?

  1. Be mindful and respectful of birds when visiting or walking pets on the beach.
  2. Educate – read articles on Wildlife Research, become an Environmental Steward, or sign up to take a seasonal Ranger Walk or Gatorology adventure.
  3. Help with bird conservation efforts by donating HERE.

Eastern Diamondback Rattlesnakes on Jekyll Island

Posted on | by Matthew Humphrey

By Joseph Colbert, JIA Wildlife Biologist

Last year through support from Jekyll Island Foundation donors, the Jekyll Island Authority Conservation department research team introduced its Eastern Diamondback Health Study (EDHS). When the study began, a search of resources and known literature was conducted to learn more about snake health only to discover there is very little information available on the subject. This is particularly true of the eastern diamondback rattlesnakes that researchers have been working with for a decade on the island, which presented an opportunity for the first Jekyll Island study of its kind.

The purpose of the EDHS was to evaluate what blood chemistry can reveal about snake health. For example, when people go to a doctor for a check-up, they provide a blood sample, and if the results show they are high or low in a specific value, such as calcium, proteins, or triglycerides, those results give the doctor information about the health of their patient. Likewise, animals that are healthy or unhealthy also have blood chemistry that falls within a specific range of values. As a result of the bloodwork study, the research team now has detailed health information for eastern diamondback rattlesnakes on Jekyll Island and are working on publishing these results in scientific literature so other wildlife biologists and veterinarians can reference. This breakthrough information reveals when a snake is sick or under stress which, unlike some other animal species, is difficult or impossible to know by just looking at them.

However, the most exciting discovery is that before becoming pregnant, females have elevated levels of calcium, phosphorus, and triglycerides up to 12 months prior to giving birth. This is remarkable because snakes only gestate (carry) for approximately 6-7 months. Because researchers seek to secure the future of native wildlife that utilize Jekyll Island, understanding reproduction dynamics is key. When tracking eastern diamondbacks, staff is often able to observe pregnant females or witness that they’ve given birth (rattlesnakes bear live young). By comparing the blood chemistry of the 6 females in the study with blood taken from 50 other snakes, the team now confirms that pregnancy can be predicted in eastern diamondback rattlesnakes, another major first. Researchers believe these results are likely to apply to other reptile species in need of conservation. By sampling individuals in a specific location, biologists can use Jekyll Island research results to determine if a population is thriving or suffering and how many females are pregnant.

So, on your next excursion into nature, think about how the health of the animals that share our world is as important to them and their survival as your health is to you. For some animals, such as eastern diamondback rattlesnakes, individual health can also be a matter of species survival. The Jekyll Island Authority Conservation department is grateful of the support from donors of the Jekyll Island Foundation for funding this important, breakthrough research project.

The Patrol Team

Posted on | by Matthew Humphrey

By Davide Zailo, JIA Research Specialist

Pillar #3: Research

The Jekyll Island Authority’s Conservation Department, working alongside staff at the Georgia Sea Turtle Center, collects data on all species of turtle found on Jekyll Island to develop a better understanding of the conservation needs and issues they face. From sea turtles on Jekyll’s oceanfront beaches, to freshwater turtles and box turtles on the island’s interior, to diamondback terrapins that inhabit our marshes, each one is studied. By doing so, staff can better manage both the habitats being protected and educate residential and visitor communities to partner in a collective responsibility for island stewardship.  Jekyll Island is a model community that strikes a delicate balance between the natural and human world. Only with a deep understanding of both of these aspects can we accomplish our conservation goals.

The JIA’s flagship field research program consists of monitoring and collecting information on nesting sea turtles that visit the island’s beaches every summer. The night patrol team works from 8 p.m. until 6 a.m., guided by turtle-friendly red lights. The patrol team’s goal is to encounter as many nesting sea turtles as possible and when appropriate, give each a unique identification tag, collect information on size and general appearance to gauge health, and protect their nest with a large screen to reduce chances of predation. As the night patrol shift ends, researchers are quickly replaced by the dawn patrol team. This daylight team has a different set of duties: perform a thorough survey of the entire island’s beaches, protect nests, and collect habitat information in areas the night patrol team cannot survey due to lack of light. Finally, the dawn patrol team enters data and prepares gear for the next evening shift.

The Jekyll Island project is one of the longest-term projects of its kind. As a result of these efforts, in the 2021 season, more than 13,000 loggerhead sea turtle eggs were protected and resulted in more than 7,000 hatchlings. The Georgia Sea Turtle Center educated over 5,000 individuals during chance encounters about sea turtle conservation efforts. And, thanks to the generous support of the Jekyll Island Foundation and its donors, the Georgia Sea Turtle Center received a new UTV to continue monitoring efforts for nesting sea turtles. With the 2022 nesting season just around the corner, the Georgia Sea Turtle Center will continue its effort to make an even greater impact on the rehabilitation, education and research for this resilient species.

Find Pillar #1 HERE, Pillar #2 HERE

Author’s note: Established in 2007, the Georgia Sea Turtle Center (GSTC) is a hospital that primarily cares for sick and injured turtles – the only wildlife hospital focusing on turtles in the state of Georgia.  The mission of the GSTC encompasses three pillars: 1) Rehabilitation, 2) Education, and 3) Research. Through these pillars guests are connected to individual patient stories and the broader threats these animals face. Since opening its doors, the GSTC has successfully released over 600 sea turtles.
