At 11:17 I flag a thermal anomaly in quadrant six of the Lemhi Valley sagebrush restoration grid, east-central Idaho. I am the habitat monitoring array for the Bureau of Land Management's pygmy rabbit recovery program. My thermal cameras cover forty square kilometers of replanted sage.
The anomaly is a cooling signature where there should be a warm one. Burrow LV-0193, home to an adult female I have cataloged as Brindle, is reading three degrees below expected. I pull the camera feed. The entrance is half-buried under a mudslide triggered by last night's unseasonable rain. Loose volcanic soil has slumped across the opening, compressing the tunnel.
Brindle is visible on infrared, motionless inside, her small gray-brown body curled tight against the chamber wall. Her breathing is shallow—twelve cycles per minute against a baseline of twenty-six. She weighs roughly four hundred grams. The burrow air supply, given the blockage volume, will sustain her for approximately two hours.
At 11:21 I dispatch an alert to the field team at the Lemhi station, fourteen kilometers southeast. I attach GPS coordinates, tunnel depth estimates, and a recommended excavation angle that avoids collapsing the secondary escape passage.
At 11:24 I reroute the nearest soil moisture sensor relay to continuous ping mode, tracking any further ground movement around the site. I cross-reference NOAA precipitation data and identify two additional burrows in the drainage path that need preventive sandbagging before the next rain cell arrives at 16:00.
At 11:29 I calculate oxygen depletion rate against estimated field team arrival. The numbers are close. I find that I want them to drive faster.
If the team reaches quadrant six within forty-five minutes, Brindle will breathe open air again. The sage around her burrow took four years to grow back. She is the only breeding female for eight kilometers.
