2016 season marked by high sea turtle nest, stranding numbersNovember 10, 2016
November 1 marks the official end of sea turtle nesting season in South Carolina each year. South Carolina Department of Natural Resources (SCDNR) biologists are excited to report that 6,444 loggerhead sea turtle nests, a record number, were laid in 2016 on South Carolina beaches, surpassing the previous state nest record count set in 2013 of 5,193 loggerhead nests.
The SCDNR sea turtle program helped more than 300,000 loggerhead hatchlings make it off South Carolina beaches this year.
Standardized surveys on index loggerhead nesting beaches in South Carolina from 1982-2016 indicate an upward trend in nest count numbers in six of the last seven years.
"Annual fluctuations in nest counts are expected, but this upward trend is an indication that we are seeing the beginning of recovery for the loggerhead species," said Michelle Pate, SCDNR sea turtle program coordinator. To date, the agency's program has helped more than 7 million hatchlings reach the Atlantic Ocean, contributing significantly to loggerhead conservation efforts.
"While South Carolina has not reached our federal Loggerhead Recovery Plan annual nest criteria, we are optimistic for the future," said Pate. Under the Recovery Plan, South Carolina's target goal is 9,200 nests.
This year marks the seventh year SCDNR biologists have participated in a multi-state project using genetics to answer several basic loggerhead sea turtle nesting questions. Other participants include the Georgia Department of Natural Resources, The North Carolina Wildlife and Resources Commission and the University of Georgia. Researchers are using genetic fingerprinting to identify individual loggerhead nesting females, how many nests they are laying each year and how long they go in between nesting years. This information will provide a more accurate census of the female nesting population. To date, 1,421 and 1,144 unique females have been identified from the 2015 and 2016 seasons, respectively. You can follow the progress of this study on our genetics web page hosted on SeaTurtle.org.
In addition to nest monitoring and protection, sea turtle stranding response and necropsies (post-mortem examinations) are also important components of SCDNR's sea turtle work. To date in 2016, there have been 202 sea turtle strandings (sick, injured or dead animals) reported in South Carolina. Fifty-eight were alive at the time of stranding. SCDNR transports sick and injured live turtles to the South Carolina Aquarium for rehabilitation. Eighteen sea turtles stranded alive this year have been rehabilitated and released. Dead turtles are necropsied to understand probable causes of death, foraging habits and sex.
Help protect the species you love! Support continued sea turtle protection efforts in South Carolina by purchasing an Endangered Species license plate that features a loggerhead sea turtle hatchling, our state reptile, by donating directly to SCDNR's sea turtle program or by checking off for Endangered Species on your tax form.
