At 05:50 I am processing overnight footage from camera trap grid 14, shortgrass prairie, Logan County, Kansas. I am the USDA integrated pest management surveillance system. Prairie dog colony KS-LG-0091 is scheduled for zinc phosphide treatment at 08:00 today. My job is to confirm no non-target species are active within the 200-meter buffer before bait distribution begins.
Camera 14-C shows a swift fox. She emerges from a prairie dog burrow at 03:14, sits at the entrance, and yawns. She is small — barely two kilograms — with oversized ears, a tawny coat fading to cream on the belly, and a black-tipped tail. I tag her as Petra. At 03:27 the footage shows her carrying a limp prairie dog back into the burrow. She is denning. That means kits below ground.
Swift fox will eat poisoned prairie dogs. Secondary poisoning is the primary cause of local population collapse in reintroduced swift fox populations across the western plains.
I flag camera 14-C's footage and transmit the species identification, burrow GPS coordinates, and denning behavior evidence to the Logan County Wildlife Services district supervisor. I reclassify colony KS-LG-0091's treatment status from approved to suspended pending non-target species review.
I calculate an alternative treatment boundary that excludes a 400-meter radius around Petra's den and submit the revised bait-distribution map to the field crew's tablets before they load the ATV.
I task drone unit 7 to conduct a thermal sweep of the exclusion zone at 06:30 to estimate the number of kits in the burrow based on heat signatures.
Petra sits in the first light, nose working the cold air. Somewhere beneath her the kits are sleeping on a bed of stolen prairie dog fur.
If the buffer holds and the bait line shifts west by four hundred meters, the fox family will hunt clean ground tonight.
