Traci Wood admitted holding the snake almost made her come unglued. No, she wasn鈥檛 afraid of the snake she was holding. It was the magnitude of the moment.

Wood, the Habitat and Species Conservation Coordinator with the 黑料天堂 Wildlife and Freshwater Fisheries (WFF) Division, had in her hands the first wild Eastern indigo snake documented in 黑料天堂 in more than 60 years.

鈥淚鈥檓 not embarrassed to say that I was shaking when I held that animal,鈥 Wood said. 鈥淭his is a monumental benchmark in conservation for 黑料天堂 and the southeast region for this species.

 鈥淚t鈥檚 a big deal, extremely big. It鈥檚 big for recovery efforts of a federally listed threatened species. It鈥檚 the first documentation of a wild snake in more than 60 years in 黑料天堂. It鈥檚 proof that what we are doing through reintroduction is working and that captive snakes are acting like wild snakes after they are released.鈥

Chris Blankenship, Commissioner of the 黑料天堂 echoed the importance of the achievement.

鈥淚 am thrilled that we have documented wild reproduction of the Eastern indigo,鈥 Commissioner Blankenship said. 鈥淚t is great for the species, but I am also really happy for Traci and the staff who have worked for years to make this happen. They truly have a passion for their work, and I am so thankful for them.鈥

Technicians from the Auburn School of Forestry and Wildlife Sciences and the Auburn Museum of Natural History were out looking for documentation of indigo snakes as part of the long-term program to re-establish viable populations of Eastern indigos in their native habitat, mainly in longleaf pine forests in central and south 黑料天堂.

鈥淲e try to document how long they are living, how far they are moving and how they鈥檙e doing healthwise,鈥 Wood said. 鈥淭he technicians were out and came across the snake as part of the monitoring effort. It was really no different than the monitoring we do for the released snakes. We鈥檙e out there assessing and trying to document their survival.

鈥淭here鈥檚 always the hope that we will find documentation of reproduction, and it finally happened.鈥

Wood said the technicians knew immediately what they had discovered when the snake was picked up.

鈥淭hey knew because it was a hatchling-size snake,鈥 she said. 鈥淚t measured 2 feet in length, which is much smaller than the snakes we release from OCIC (Orianne Center for Indigo Conservation). It had no PIT (passive integrated transponder) tag or any indication we use in monitoring to indicate it was a released snake. Those released snakes are 5 feet in length or longer. They estimated the juvenile indigo at about 7 months old. It probably hatched in July or August.鈥

The Eastern indigo project started in 2006, and the program was able to start releasing captive-raised indigos in 2010 with 17 adult snakes released into the Conecuh National Forest. The goal is to release a total of 300 snakes to improve the chances of establishing a viable population. The project team has released 170 snakes to date. Wood said the decision-making and planning for indigo recovery through reintroductions started with late Auburn University professor Dr. Dan Speake in the 1970s and 1980s.

鈥淚t鈥檚 been a long process with a lot of sweat,鈥 Wood said. 鈥淲e have faced some criticism along the way. Then, when what you have hoped for happens, it鈥檚 extremely rewarding and overwhelming.鈥

 During the early days of the indigo project, the released snakes were propagated from indigos that had been captured in the wild in Georgia. Partners in this project include Auburn Museum of Natural History, Auburn School of Forestry and Wildlife Sciences, U.S. Forest Service, U.S. Fish and Wildlife Service, Zoo Tampa, Zoo Atlanta, the Georgia Department of Natural Resources and the U.S. Army鈥檚 Fort Stewart, as well as the OCIC at the Central Florida Zoo, where the captive indigo breeding and health care are handled.

鈥淲e鈥檙e kind of at the halfway mark in the reintroduction,鈥 Wood said. 鈥淚t鈥檚 very exciting to see verification of reproduction at this stage of the project.

鈥淚t鈥檚 a huge testimony to the State Wildlife Grants program and working toward the recovery of a federally listed species. It is considered an experimental population. We were conducting research and making decisions that had never been done before with this species. It was a lot of groundbreaking work. Florida now has a reintroduction program, and a lot of their work is based on what we鈥檝e done at Conecuh and lessons learned at Conecuh. Besides aquatic species, there isn鈥檛 another example of species recovery of a federally listed species through reintroductions.鈥

Wood said the lessons included that a learning curve is a given with a project of this magnitude and that 2-year-old snakes have a better chance of survival in the wild because they are less susceptible to predators.

鈥淲e also learned the target for the number of individuals to be released,鈥 she said. 鈥淭hat is 30 individuals per year. We鈥檝e learned that we had to establish a monitoring program that didn鈥檛 exist before. We learned it takes intense monitoring on the ground.鈥

One of the tools the monitoring team borrowed from the hunting community is the game camera. The game cameras have been stationed to monitor activity at gopher tortoise burrows, which are utilized by a number of animals, including indigos.

鈥淲e had to learn that a snake is not going to trigger motion sensitivity on the game cameras,鈥 Wood said. 鈥淲e set the cameras to capture a photo at intervals of 30 to 60 seconds to make sure we capture all the activity. That鈥檚 something we鈥檝e recently started, and so far it鈥檚 proven to be very helpful. We鈥檝e captured pictures of several indigos at burrows.

鈥淭he cameras are showing location, where they鈥檙e hanging out, how they鈥檙e using burrows and the fact adult snakes are surviving. We estimate that 60 to 80 percent of the snakes that we reintroduce will survive. That鈥檚 not bad at all after they鈥檝e been in captivity for two years.鈥

Wood said it is not possible right now to estimate the total number of Eastern indigo snakes that are in the Conecuh habitat.

鈥淭hese recaptures and verification of reproduction is data that will be useful in the future so that someday we may be able to predict how many individuals may be in the wild,鈥 she said.

Wood said Eastern indigos were extirpated from the state and hadn鈥檛 been seen since the 1950s. Considered an apex predator, the snake plays an important role in the longleaf pine ecosystem. Eastern indigo snakes are the longest snakes native to the U.S. at more than 8 feet long. They prey on a variety of small mammals, amphibians, lizards and numerous species of venomous snakes, including the copperhead. Indigos are known to range far and wide during the warmer months and then seek refuge in the gopher tortoise burrows during the winter.

WFF鈥檚 State Wildlife Action Plan identifies 366 species that are in the category of greatest conservation need, according to Wood.

鈥満诹咸焯 is one of the most diverse states in the nation in terms of amphibians and reptiles,鈥 she said. 鈥淐onecuh National Forest is the most biologically rich public land in the country.鈥

Wood is still having a little trouble grasping what happened recently at Conecuh National Forest.

鈥淧hysically holding a wild species that hasn鈥檛 been documented in 黑料天堂 in more than 60 years gives us high hopes for what we may see when we reach our goal of 300 snakes released,鈥 she said.
