Sea Turtle Conservancy



"It is the mission of Sea Turtle Conservancy to ensure the survival of sea turtles within the Caribbean, Atlantic and Pacific through research, education, training, advocacy and protection of the natural habitats upon which they depend."

The Sea Turtle Conservancy, formerly known as the Caribbean Conservation Corporation, is the world's oldest sea turtle research and conservation group. An international nonprofit 501(c) 3 organization, Sea Turtle Conservancy was founded in 1959 by world-renowned sea turtle expert Dr. Archie Carr to save sea turtles from eminent extinction through rigorous science-based conservation. Headquartered in Florida, the organization carries out worldwide programs to conserve and recover sea turtle populations through research, education, advocacy and protection of the natural habitats upon which depend upon. Over the course of 55 years, Sea Turtle Conservancy's research programs have yielded much of what is now known about sea turtles and the threats they face, and the organization is applying this knowledge to carry out the world's most successful sea turtle protection and recovery programs.

Green Turtle Crawl!


This morning was an interesting morning to be on the beach! We had our first green turtle crawl onto the beach ....early for a green turtle and she didn't dig a nest. Green turtles are uncommon on Sanibel.




The characteristic tail poke/drag is missing, and the front right flipper appears to be damaged, but you can tell it's probably a green because the flipper marks are slash like (rather than comma shaped) and symmetrical (rather than alternating like a loggerhead).Greens usually nest later in the  season as I mention, which makes this especially interesting.  Too bad it was a false crawl so we'll never be absolutely sure. FWC did confirm that they also thought it was a green turtle. It was fun to use field science to try and determine the species.

Another turtle, a loggerhead was caught finishing up her nest at dawn the other morning by another volunteer who provided pictures.





And the most exciting event of all was recorded by a Venice, Fl resident who spotted the rarest turtle of all the Kemp's Ridley digging a nest on Venice Beach on May 9. Check out this Youtube video.

So Turtle Season is really gearing up!

My First Turtle Nest Officially Staked!!



I'm so excited! Turtle season has officially started, the turtles are finally coming in to nest, and I have gotten to stake a nest.  On Sunday I went out to the West end of Sanibel on the Gator vehicle. It was another beautiful morning, a bit on the cool side, but beautiful none the less. After loading the gator with supplies we drove down to Tarpon Bay road where we entered the beach. The sun was barely above the horizon but people were already setting up for the day, fishing and shell collecting. Riding a vehicle on the beach is a whole new experience. Parts of the beach are eroding and little shore birds are also nesting. You must drive, look for tracks, avoid large holes dug by enthusiastic children, miss little chicks and eggs, look for trash and not hit any tourists with the gator. Kelly, the turtle rescue coordinator, and I shared the responsibility. We were both excited and hopeful that we would at least spot a false crawl, but no luck.

Today we went out on the East end. Several more false crawls had been reported on Monday and Tuesday, a nest was also laid, so we expected to hear from the walkers on the East end that there had been some activity.  By 7 in the morning the calls from the beach walkers started to come in. Zone 6 had a nest!! Off we went, this time in a regular car to exam it and stake it.

Looking at this section of beach, the first thing you notice is the gentle escarpment up from the tide line.


It was sloped enough that this momma turtle had no problem climbing up about two feet to lay her nest on higher ground. This was a good spot because only the highest storm tide will threaten this nest.

Kelly asked me which direction the tracks indicated where the turtle had entered and left the nesting site.  Of course I had it backwards. It's important to know direction so that you can estimate where the egg chamber is located. You don't want to accidentally place a stake in the egg chamber.



France was the walker who discovered the crawl. Kelly asked her to estimate where the egg chamber was located based on the signs left by the nesting turtle. It was interesting to discover that the chamber was actually not in what appeared as the deepest part of the body pit the turtle had dug. Rather it was to the right and back in an area she had spent time flipping sand onto.

We don't verify the egg chamber by probing for fear of damaging it, so a good estimate is essential when it comes time to excavate a nest after hatching or in case of a failure to hatch. You can dig a long time in the wrong spot.




We then laid out the stakes, marked the location, gathered relevant data to be recorded and taped the nest.

It was a great morning and I look forward to the rest of the season and the surprises, challenges, and adventures to come.
