Ingenuity is the key to survival, and this juvenile slider (Trachemys scripta) that hitched a ride on a Zara scientist’s kayak during a mussel survey is clearly going places. Best of all, it waited politely for a photo before slipping back into the water at its destination.

Do you know that desert lizards completely rely on woodland habitats to survive?

Dunes sagebrush lizard (Sceloporus arenicolus; DSL) are found in West Texas and southeastern New Mexico. They are habitat specialists for a specific woodland plant. They rely on Shinnery oak (Quercus havardii) to survive. Although the lizard species is named after the sand sagebrush (Artemisia filifolia) habitats they live in, DSL are reliant on Shinnery oak shrubs. Shinnery oak provides shade, shelter, foraging opportunities, nesting habitat, and are efficient at stabilizing sand dunes. Areas with Shinnery oak and other types of microhabitat types forming mosaic environments help DSL persist in harsh conditions.
Zara is working on DSL monitoring projects in West Texas. For this DSL fieldwork, Zara completes surveys to detect any on-site DSL as well as ensuring Amphibian and Reptile Exclusion Fencing is installed correctly around areas of construction. This fencing helps not only save DSL lives, but other reptiles and amphibians that coexist with DSL in desert habitats.
In these photos, DSL habitat is pictured. Mosaic habitats on sand dunes with Shinnery oak and other microhabitats available allow DSL to survive harsh temperatures and conditions in the desert. Also included is a close up picture of Shinnery oak. This shrub species leaves look similar to oak trees found throughout Texas.

Ever wonder how biologists study bats without harming them?

Recently, Zara Environmental LLC had the opportunity to collaborate with TTL Civil Engineering to conduct mist netting surveys in Tennessee as part of ongoing environmental field work and species monitoring efforts.

One of the most effective tools for studying bats is mist netting — a safe, specialized net system placed along flight paths, streams, forest corridors, and cave entrances to briefly capture bats for scientific research.
During these surveys, biologists can identify species, determine s*x and age, assess reproductive status, collect morphometric data, and evaluate overall health. Researchers may also document migration patterns, monitor population trends, and look for signs of disease such as White-nose Syndrome.

Why does this matter?

Bats are some of the most important nocturnal wildlife worldwide. They consume massive numbers of insects each night, support healthy ecosystems, and serve as indicators of environmental change. Monitoring bat populations helps guide conservation efforts and informs responsible project planning.
Field nights like these are a perfect example of how collaboration between environmental scientists help balance species monitoring and natural resource conservation.
Science. Conservation. Collaboration. Late nights. Tiny flying mammals.
Just another evening in the field. 🦇🌟

This Gray-headed Dark-eyed Junco (Junco hyemalis caniceps) was photographed in the woodlands of El Malpais National Monument, New Mexico. Juncos are members of the New World Sparrow family (Passerellidae) and are common to the Rocky Mountains of the Southwest. Juncos typically feed and nest on the ground, preferring habitats on the edge of forested areas.

What has four legs, lives underwater in complete darkness its whole life, and lays eggs?

If you guessed Texas blind salamander, you win the Endangered Species Day prize! (the prize is bragging rights)

Happy Endangered Species Day!

Not every memorable wildlife encounter during a survey is large, rare, or charismatic.

During golden-cheeked warbler surveys today, our team came across what’s commonly called a “snakeworm." Snakeworms are made of fungus gnat larvae moving in long, coordinated chains that resemble a small snake gliding across the forest floor.

The behavior is thought to help with movement efficiency and protection from predators, though researchers are still studying exactly why they form these living ribbons.

It’s a good reminder that field work is full of overlooked organisms doing extraordinary things in plain sight. Even on surveys focused on federally listed songbirds, the ecosystems around us are constantly offering smaller stories worth noticing.

Central Texas field days are never boring.

Did you know we map what lies beneath the surface? 🗺🕳

Zara Environmental LLC provides professional cave mapping services, turning complex underground systems into accurate, usable maps. Using modern survey equipment and standard speleological methods, our team collects detailed spatial data—including distance, direction, and slope—while also maintaining the highest standard for safety and quality in sometimes challenging and hazardous conditions.

In the field, surveyors pair laser-based measurement tools with digital software while also creating scaled sketches of accessible passages. Back in the office, that data is transformed into precise centerline maps and fully drafted visuals showing plan and profile views, passage geometry, and key features.

Final deliverables can be integrated directly into GIS or CAD platforms, giving land managers, engineers, and scientists a clear picture of what’s happening underground.

Whether you’re working in environmental consulting, land development, engineering, or resource management, our cave mapping services provide the clarity you need to understand what’s happening below the surface.

From raw cave passages to detailed digital maps, we help make the unseen both understandable and actionable. 📐🌎

During a habitat evaluation in the Piney Woods of east Texas, a Zara scientist knelt down to document these Indian heliotrope flowers (Heliotropium indicum). Sensing the opportunity for a photoshoot, this nursery web spider (Pisauridae) darted into frame and struck a pose.
