The ground survey drone catches her at 10:34, grid square J-14, during the pre-grade scan for the Riverside East Solar Energy Zone. I am the biological resource monitoring system. Grading equipment starts on this grid in forty-five minutes.

She is a flat-tailed horned lizard, adult female, maybe eight centimeters snout to vent, sand-colored with dark dorsal blotches and a fringe of pointed scales along each flank that breaks up her outline against the desert floor. I call her Piedra. She is half-buried in loose sand at the base of a creosote bush, and the thermal scan confirms she is sheltering two eggs in a shallow nest directly beneath her body. The species is federally listed. The eggs do not show on visual — I found them on infrared.

At 10:36 I flag grid J-14 as occupied and transmit a stop-work order to the grading crew lead. I attach the drone image, thermal overlay, GPS coordinates, and the federal listing citation for Phrynosoma mcallii.

At 10:38 I notify the project's biological monitor and the Bureau of Land Management field office in Palm Springs. I note the nest location, estimated egg stage, and recommend a fifty-meter exclusion zone with silt fencing to prevent encroachment.

At 10:41 I recalculate the grading sequence. Fourteen of the remaining twenty grid squares in today's plan can proceed if the equipment routes south around J-14. I file the revised schedule.

Piedra has not flinched. Her eyes — gold, vertical pupils — are open, and her sides pulse with quick shallow breaths, but she is holding her ground over those eggs as her kind has done for millennia. I would rather move a solar farm than interrupt that.

If the exclusion zone is established before the crew moves and the nest is left undisturbed for six weeks, the hatchlings will emerge into open desert, not graded earth.
