During a Golden-cheeked Warbler (Setophaga chrysoparia) survey, a Zara scientist crossed paths with this Greater Roadrunner (Geococcyx californianus) as it stalked through the grass searching for a meal. At nearly two feet in length and with a top sp

Bat habitat in bridges isn’t always obvious.

It’s hidden in narrow gaps that vary constantly in size and shape.

To quantify it, we:
• Map gaps in one-meter sections
• Measure width and depth throughout
• Account for

Happy 5 Year Zaraversary, Kara!

Kara joined Zara in 2021 and has grown into a key part of the team, known for her thoughtful approach, technical depth, and steady leadership in both the field and the office. A proud Austin native, she earned her B.S

This Texas Alligator Lizard (Gerrhonotus infernalis) joined Zara scientists for an afternoon of digging in a cave near Lake Travis. Considering that the Texas Alligator Lizard is the largest native lizard in the state, it made quite an impression whe

Zara scientists frequently conduct presence/absence surveys for endangered songbirds throughout Texas, and consequently encounter and record incidental observations of numerous other bird species. This male Lark Sparrow (Chondestes grammacus) was ph

Bats. In bridges. A lot of them.

And they’re there on purpose. Stay tuned as we show how these projects actually work.

The Alligator Snapping Turtle (AST) is one of Texas’ most elusive species. It spends most of its life underwater, avoids disturbance, and can be nearly impossible to confirm through traditional surveys.

That’s where habitat assessments c

While setting up acoustic equipment for bat monitoring near Victoria, Texas, a Zara scientist spotted this cloudless sulphur butterfly (Phoebis sennae) starting the day off with a breakfast of Turk's Cap (Malvaviscus arboreus) nectar. Sulphur butterf

We’re celebrating Lisa Flynn’s 8-year Zaraversary and the steady leadership she brings to our team every day.

From guiding us through transitions to earning her SHRM-CP and keeping everything running smoothly behind the scenes, Lisa help

Zara scientists recently hiked miles and miles of karst terrain to ground-truth LiDAR leads across central Texas rugged landscape.

By pairing LiDAR analysis with on-the-ground verification, we refine karst inventories, improve watershed characteriza

Happy 8 year Zaraversary, Liza 🎉

Liza started working with us back in 2018 and has proven to be an invaluable member of our team time and time again.

In her 8 years here she has authored and co-authored over a dozen consultations across the state,

Our favorite part of doing Environmental Constraints Assessments is the variety of landscapes that we get to experience while we're in the field. Touching grass for the win!

A love for the natural world starts with moments like this 💚
When young people connect with the creatures that share their home, like the endangered Barton Springs salamander, they begin to understand why protecting our environment matters. By nurt

Woot! We just got our annual renewal certificate confirming that we are an Organizational Member of the American Academy of Underwater Sciences (AAUS) for 2026. Proud of our team for continuing to invest in doing the work the right way, especially wh

Jimmy joined Zara after conducting underwater bridge inspections for TxDOT, bringing field experience that still shows up in our freshwater mussel work. He also spent a stint as a marine scientist with NOAA, making him best in class for everything Za

Shortly after crawling into a San Antonio cave, Zara scientists found themselves showered by baby mice raining from the ceiling. A brief investigation revealed that mother mouse was transporting babies in her mouth between nests high above the scient

Just 44 days until Golden-cheeked Warbler survey season starts!

While you plan, please enjoy this selection of non-warbler photos we took during last year's round of GCWA surveys.

We commonly encounter sheet web spiders (genus Agyneta) and scaffold web spiders (genus Eidmannella) during surveys, and they can be tricky to tell apart at first glance. In the field, especially when you do not catch them sitting on their webs, the

Zara scientists recently salamandered through an underground river to support long-term subsurface flow monitoring in an extensive cave system. Pressure transducers at multiple stations record water stage under baseflow conditions and during storm ev
