LITTLE ROCK, Ark. (Arkansas Game and Fish Commission) – Forty-three eastern collared lizards bred at the Little Rock Zoo found new homes in the Arkansas Ozarks last week thanks to an innovative partnership between the zoo, Arkansas Game and Fish Commission, University of Arkansas, University of Central Arkansas and the Arkansas Cooperative Fish and Wildlife Research Unit. 

While not the first attempt at relocation of eastern collared lizards, which are listed as a species of greatest conservation need in Arkansas, this is the first time researchers and biologists have collaborated with the zoo to provide yearlings to introduce in newly restored habitat.

The eastern collared lizard is the largest lizard species found in Arkansas. Some males may reach 14 inches long, while the females tend to be a bit smaller. Sometimes referred to as “mountain boomers,” the lizards are particularly striking with vibrant yellow, green and teal blue colors in males and females sporting more muted greens with red-orange markings. The species has experienced declines in the last few decades, primarily as a result of the loss of sparse, rocky glades. Suppression of fire along many of these thin-soiled mountain areas has allowed cedars and other woody plants to invade these spaces, changing the plant communities required by animals that historically called them home.

The Collared Lizard Conservation Team, as well as several other federal, state and private agencies have been focused on restoring glade habitat throughout the state to benefit many species, including northern bobwhite, wild turkey and several glade endemic plants, arthropods and vertebrates. Restoration efforts include prescribed fire, cedar removal, invasive plant treatments, prairie plant reseeding and the addition of large rock piles (the primary refuge for many glade species).

For the last year, the conservation partners have worked on collaborative efforts including a captive propagation program at the zoo to provide lizards for reintroductions to restored habitat sites. Last week’s release was the first of many planned for the future to re-establish this valuable Arkansas treasure to the landscape before it is too late. 

The team anticipates reintroducing several more populations to other locations in the state, which will include State Parks, AGFC and private land.
