Gopher tortoise conservation in the USA


This October 2014 video from the USA says about itself:

We all know the story of the tortoise and the hare but it might be time to rethink the concept of tortoises being slow!

On this week’s adventure Coyote’s chasing after some seriously speedy Gopher Tortoises on the Tortuga Trail Wildlife Preserve at Florida Atlantic University.

Working alongside tortoise conservationist Jessica Huffman, Coyote will have to be quick on his feet to get an up close look at this remarkable keystone species…and unfortunately for Coyote he’s also in for one “BIG” surprise! You aren’t going to want to miss this episode of Breaking Trail!

Special Thanks to Jessica Huffman and all the members of SEEDS who helped in the making of this episode. Keep up all the incredible conservation work, you guys are the best!

Breaking Trail leaves the map behind and follows adventurer and animal enthusiast Coyote Peterson and his crew as they explore a variety of wildlife in the most amazing environments throughout North America!

From the University of Georgia in the USA:

Giving tortoises a ‘head start’

Raising gopher tortoises in captivity may boost wild populations

September 4, 2018

Research from the University of Georgia indicates that head-starting — raising a species in captivity and releasing it into a protected habitat after it has grown large enough to be less vulnerable to predators — is a useful intervention for boosting the state’s gopher tortoise population, which has been declining in numbers for decades due to predation, poaching and loss of suitable habitat.

Seventy percent of head-started tortoises raised from donor eggs were still alive a year after release at Yuchi Wildlife Management Area in Burke County, according to research by Tracey Tuberville and Dan Quinn. They published their findings in the Journal of Wildlife Management.

The gopher tortoise, Georgia’s state reptile, is a keystone species whose burrows provide shelter for more than 250 other species, said Tuberville, associate research scientist at the Savannah River Ecology Laboratory and adjunct faculty at the Warnell School of Forestry and Natural Resources.

Despite predation risks at the release site, survival rates were higher than survival reported for their wild counterparts, according to Quinn, a graduate student at SREL and Warnell during the research.

Quinn conducted two soft-releases of yearlings at YWMA during consecutive years. The team said the second release was the largest tortoise release in the state to date.

“We initially released the tortoises into pens to acclimate them into the natural environment,” he said. “This gives them time to construct a burrow and in theory it reduces predation risk.”

Forty-two of 145 yearlings were radio tracked and monitored for a year following the soft releases, providing information to inform future head-starting efforts.

Tracking data revealed that the juveniles demonstrated a strong rate of site fidelity, remaining together in a protected area, which allows them to reproduce. This means the soft-release technique is not necessary, according to Tuberville.

Instead, the researchers will implement multiple releases in various locations to help reduce predation risk. Predators included fire ants, raccoons and dogs, with fire ants accounting for the majority of fatalities.

Head-starting efforts at YWMA will continue with tortoises that are 2 to 3 years old, an age when they are less susceptible to predators, Tuberville said. Additional research will evaluate whether the positive effect on post-release survival warrants the additional time in captivity.
