His research this time around focuses on 1) studying the inundation tolerance of developing sea turtle embryos, and 2) the effect of Leave No Trace ordinances on nesting success. In past years, Matt has investigated the changes in incubation conditions associated with nest relocation and mapping wave runup exposure to identify high-risk nesting locations. To better inform these management strategies and tools, more information is needed on how well developing sea turtle embryos “hold their breath”. How long can embryos remain underwater and still hatch successfully? How does this tolerance vary with the timing of inundation relative to embryonic development and the frequency of inundation? Matt is using HOBO U20L-04 water level loggers to answer these questions, including 2 loggers donated by Onset Computer Corporation. Tropical Storm Alberto arrived in the northern Gulf of Mexico very early in the nesting season, so only 2 nests were affected. The peak of hurricane season is still to come in August and September – and the loggers are ready and waiting. This project has been funded by a Section 6 grant from the Alabama Department of Conservation and Natural Resources.
The second component of his research this summer constitutes the final year of data collection on a multi-year project tracking the nesting success across Baldwin County, Alabama. In 2015, the cities of Gulf Shores and Orange Beach enacted Leave No Trace ordinances. The “Leave Only Footprints” program as it is called forces beachgoers to remove their equipment from the beach no later than 1 hour after sunset or face civil penalties. This program does not apply to unincorporated Fort Morgan, and the 2 local protected areas – the Bon Secour NWR and Gulf State Park – already have their own versions of the Leave No Trace ordinance. By comparing nesting data before and after the enactment of the “Leave Only Footprints” program and within each year across the county, Matt will be able to assess if the program has improved nesting success, or at least decreased the frequency of obstructed crawls, in Gulf Shores and Orange Beach.
Unfortunately, on Saturday 14 July, the need for such ordinances was demonstrated when a mature female Kemp’s ridley was found washed up during morning nesting patrol on the Bon Secour NWR apparently strangled by a beach chair. Matt assisted the Alabama Sea Turtle Stranding and Salvage Network in documenting the event and collecting the animal for later necropsy at the NOAA facility in Pascagoula, Mississippi. Images he captured of the turtle quickly went viral on social media and various news outlets. Posts on Matt’s personal Facebook page and the pages of Fort Morgan Share the Beach and the Bon Secour NWR have been viewed over 600,000 times and shared almost 9,000 times with almost 5,000 reactions. Now this’ story on the incident has been viewed 1 million times and shared over 12,000 times. The story was covered in the:
- NBC15, USA
- New York Times, USA
- Daily Mail, UK
- Global News, Canada
- Huffington Post, South Africa
Share the Beach has reached out to the Baldwin and Mobile County commissioners along with the governor of Alabama to urge them to support an expansion of the “Leave Only Footprints” program beyond the city limits. They, and Matt, hope that the images, though graphic, will encourage beachgoers to remove equipment from the beach at the end of the day, discard of damaged equipment properly, and help combat marine debris to prevent future impacts to wildlife.
When not in the field, Matt has been working on several manuscripts detailing his previous research in Alabama. Be on the look-out for his nest relocation manuscript currently in press in Chelonian Conservation and Biology and future manuscript on wave runup mapping.
