These were when therefore populous, the lizards had been backyard favorites across the state. Docile and slow, these people were very easy to get and created for fun summertime animals. Some Texans keep in mind maintaining the lizards in a shoebox underneath the bed. Other people remember holding pillowcases high in lizards to trade at Boy Scout jamborees.

Then, gradually and inexplicably, they started initially to vanish.

Fire ants, the insidious South American invaders that destroy lawns and pack painful venomous bites, will be the many oft-cited perpetrators. They’ve decimated populations of harvester ants, the primary diet for the Texas horned lizard. In addition they destroy lizard nests and consume hatchlings.

Individual disturbance arms a number of the blame too. Urban sprawl while the spread of pesticides truly harmed the lizard’s prospects that are horned.

By enough time researchers noticed the lizard that is horned vanishing, it absolutely was nearly far too late. Now, you’re not likely to locate a lizard that is single the crazy east of this Interstate 35 corridor. You’re very likely to see them in south and far west Texas.

Horned observations that are lizard

The website iNaturalist.org crowdsources the observation of varied species in the open. Below is just a map of unconfirmed, public-submitted sightings of horned lizards in Texas by iNaturalist contributors:

About a decade ago, TCU’s Williams joined up with an endeavor with Parks and Wildlife and Texas zoos to analyze and protect the lizard that is horned.

Barber’s group in the Fort Worth Zoo pioneered breeding techniques, learning just how to effectively enhance the lizards in captivity. Others just like the Dallas Zoo have actually accompanied your time and effort.

“We’re all sort of working together for the typical good,” said Nathan Rains, a wildlife variety biologist with Parks and Wildlife.

Early efforts, such as for instance increasing lizards to adulthood before release or going wild-caught lizards from one area to some other, were discovered become very costly or impractical.

Just last year, Parks and Wildlife released hatchlings — just a couple of months old — in an effort to determine a population that is stable. Sixty-three infants through the Fort Worth Zoo had been released at Mason Mountain, an effort run. It is ambiguous if some of those have actually survived, simply because they were too little to transport radio monitors widely used on adult lizards.

At the conclusion of this past year, Parks and Wildlife and also the zoos settled for a goal that is new 300 hatchlings for release by September 2018. That quantity, they guessed, would offer the lizards a better chance to achieve adulthood, type and produce their very own offspring that is wild.

“Nobody’s more optimistic if it’s going to work yet than I am,” Rains said, “but we don’t know.”

Tinder for lizards

Definately not the pink flamingos wading close to the Fort Worth Zoo’s entry, after dark saltwater crocodile drifting lazily alongside his big glass window, behind the air-conditioned building where Mexican long-nosed bats dart forward and backward in a darkened space, a little building far from general general public access functions as head office when it comes to horned lizard breeding system.

The lizards spend their winters in the walk-in fridge. Keepers enhance the temperature to simulate the arrival of springtime in belated March.

At 66 degrees, it is time for the wake-up call.

A sleepy lizard cracks open a watch as a sizable hand pulls her away of this sand and brushes granules from her face.

“When they arrive out covered in sand such as this,” says Peltier, the zookeeper, “it’s adorable.”

The lizard, No. 207121 in accordance with a spreadsheet to Peltier’s right, has three dots of nail polish on her straight back: Green-Green-Black. Every person is identified by its six-digit quantity together with unique polish that is nail the zookeepers use each time the lizards shed their epidermis.

Peltier places Green-Green-Black onto a scale that is small. Thirty-five grms, just like whenever she went into hibernation back in November. As Peltier markings down the dimension, Robyn Doege, manager of aquatics, holds the lizard up to a tank that is small other females.

Each lizard’s DNA has been tested by Williams at TCU. Those DNA results go into some type of computer system that analyzes every person for the best possible match that is mating.

The target: Pair a man and female lizards to generate the essential genetically diverse offspring feasible. Weed out of the lizards that are related you will need to pair wild-caught critters with people created when you look at the zoo.

“It’s like Tinder for horned lizards,” Doege stated.

The lizards at the Fort Worth Zoo are clearly ready for action within a few weeks of waking from hibernation. They’ve been in bachelor and bachelorette tanks, starting to warm up and needs to go.

Meet up with the lizards

The Fort Worth Zoo keeps a breeding stock of approximately 30 adult lizards. Each lizard is identified by an original six-digit rule and a series of nail polish dots painted on its back. Find out about the whole tales of four of the iconic Texas critters.


This male was created in the great outdoors and donated to your zoo in September 2017. He’s young, however it’s uncertain exactly just how young. This is his very first 12 months become paired for breeding during the zoo, and zookeepers determined their best hereditary matches had been two bigger, more capable females. “We’re providing him a go,” said Robyn Doege, a manager at the zoo.


Big Purple, as she’s called by keepers, is just a model lizard. She’s been photographed by TCU Athletics and showcased on billboards around Fort Worth on her especially photogenic visage. She came to be in the great outdoors, and had been taken to the zoo in October 2011. Since that time, she’s been combined with a true wide range of men, but has not yet produced any offspring. She’s only laid one clutch of eggs, in 2014, but none of them hatched. This year, she would not lay any.
