After leaving St. Petersburg at 5:00 am and driving 189 miles north to Ichetucknee Springs State Park (Columbia County, Florida), Andrew Farren and I joined two of The Big Turtle Year’s partners: Dr. Jerry Johnston (Santa Fe College) and Eric Munscher (Turtle Survival Alliance - North American Freshwater Turtle Research Group) for a turtle survey on the spring-fed Ichetucknee River. This research project began in 2013 and is led by Jerry and Eric, along with co-principal investigator Dr. Joseph Mitchell (Mitchell Ecological Research Service). Nearly 60 individuals who really like turtles were there to canoe, snorkel, and capture as many as possible. Andrew and I found a Florida red-bellied cooter (Pseudemys nelsoni) and a Suwannee cooter (Pseudemys concinna suwanniensis) swimming in the thick eel grass that covered most of the bottom of the section that we worked.

That brings our count up to six species and completes the three species of Pseudemys which occur in Florida. Four additional species were captured by other snorkelers: peninsula cooter (Pseudemys floridana peninsularis), yellow-bellied slider (Trachemys s. scripta), loggerhead musk turtle (Sternotherus m. minor), and common musk turtle (Sternotherus odoratus). I had already observed the first two species in February (see The Big Turtle Year: Update #2). Just to keep things honest, the musk turtles were not included in the count for The Big Turtle Year since I neither saw nor captured either species. In fact, the first time that I saw them they were in large plastic containers at the processing station. I will be chasing turtles on three central Florida rivers during the next two months, so I expect to get the two species of musk turtles at that time.

Turtle Survival Alliance Report from the Field

Meet Carl James Franklin (Amphibian and Reptile Diversity Research Center, The University of Texas at Arlington Department of Biology), one of our partners with The Big Turtle Year project. George L. Heinrich will join him in Texas in late April to search for dozens of species that occur in the Lone Star State. It should be quite an adventure! Please visit the following Turtle Survival Alliance sites to learn about the incredible conservation work they do for turtles around the world.

The Big Turtle Year: Update #2

Species #2: Peninsula cooter (Pseudemys floridana peninsularis)

I am back from a recent trip to the Galapagos Islands where I saw lots of really big turtles, but that’s another story and unrelated to The Big Turtle Year. Since my return to Florida, Tim Walsh and I have continued to work with our project partners on planning and logistical concerns that need to be addressed in order for us to find 58 more species during the current calendar year.

Our strategy is to locate as many species as possible in Florida before we begin visiting other regions of the country in the spring. Florida’s diverse habitats support 27 of the 59 species (45.8%) known to occur in the United States. The more species that we can locate in Florida, the less species we will have to search for in other states where they also occur. This will make it possible to focus on other species when we are out of state and decrease the overall cost of the project. We have now raised $3,000 and are very grateful to our sponsors. Individuals who wish to support this conservation education project can donate at our GoFundMe site (www.gofundme.com/BigTurtleYear) or mail checks directly to FTCT as many individuals have done.

We picked up three more species today during the field session of a Turtle Science course that I am currently teaching at Boyd Hill Nature Preserve (St. Petersburg, Florida). This ecologically rich, urban nature preserve supports 10 species of native turtles. With the temperature reaching the low 70s by early afternoon and a sunny sky, nine students joined me in a search for aquatic turtles at a relatively small, man-made, freshwater pond. One peninsula cooter (Pseudemys floridana peninsularis), two Florida softshell turtles (Apalone ferox), and two red-eared sliders (Trachemys scripta elegans) were observed surface basking and swimming. Although the latter species is native to north Florida, it is not native to the Tampa Bay region. Further, the subspecies T. s. elegans, is not native to the state at all. Due to the pet trade, red-eared sliders are now common in many locations outside of their native range and unfortunately can be found in several countries around the world. In addition to the above, we saw an adult gopher tortoise (Gopherus polyphemus) foraging along the side of the trail. Our first four species were all observed at Boyd Hill Nature Preserve, but we will be visiting several other sites between now and the end of March.

The Big Turtle Year: Update #1

Species #1: Gopher tortoise (Gopherus polyphemus)
Location: Boyd Hill Nature Preserve (St. Petersburg, Florida)
Date: 1 January 2017

One down and 58 species to go. Today was the first day of the Florida Turtle Conservation Trust’s new initiative, The Big Turtle Year, which will be occurring throughout the United States during 2017. Long in the planning, this conservation education project will increase awareness regarding the status of these often overlooked and ecologically significant animals. Individuals who wish to support our efforts can donate at our GoFundMe site (www.gofundme.com/BigTurtleYear) or mail checks directly to FTCT as many individuals have done.

As planned, we started our year-long quest at Boyd Hill Nature Preserve (St. Petersburg, Florida) with a search for gopher tortoises (Gopherus polyphemus). This location was selected for symbolic reasons as it is a special place that is close to my heart. I have studied the herpetofauna of this preserve for over 25 years, and have conducted several burrow surveys of this fragmented population (estimate of 137 tortoises) located within a city-owned nature preserve. Data collected is being used to guide upland habitat management efforts and to address concerns regarding minimum viable population and minimum reserve size.

I was joined by two friends, Andrew Farren (project partner) and Jaime Gonzalez (current student in my Turtle Science course), on the upland trails in an area known to have a large number of tortoise burrows. The temperature reached 79 degrees by 1:00 pm and we observed a total of nine tortoises over the next 1.5 hours, including a hatchling at a burrow which I have been monitoring for the past two months. I consider this to be a great start for what should be a great year. Happy New Year to everyone!

The Big Turtle Year Begins January 2017

Plans for The Big Turtle Year are well underway. We recently met with potential project partners and sponsors at the Turtle Survival Alliance conference held in New Orleans this month. Interest in this conservation education project is strong and we look forward to working with multiple partners. We also completed two reconnaissance trips to the Midwest and Gulf Coast regions of the United States, with 14 species observed.
