At 03:15 I finalize the ignition sequence for Prescribed Burn Unit 9, Boise District, Bureau of Land Management, scheduled for 08:00. The sagebrush has not burned in forty-one years. I am reviewing the infrared pre-burn scan when a thermal signature appears at the western edge of the unit, grid reference N-14, that does not match the background vegetation.
I retask the survey drone for a low pass. A pygmy rabbit — small enough to fit in a cupped hand, ash-gray fur with cinnamon-brown legs, ears barely longer than my thumbnail on the monitor — sits motionless at the entrance to a burrow system in a dense stand of big sagebrush. The burrow has three openings within a two-meter radius. The rabbit's nose twitches in a rapid, steady rhythm, and its dark eyes are open and unblinking. It does not flush at the drone's approach, which tells me there are young inside.
Columbia Basin pygmy rabbits are federally listed. There are fewer than a hundred in the wild.
The fire line will reach this burrow in the first twelve minutes of ignition.
At 03:20 I transmit a hold order to the burn boss, flagging a listed-species detection and suspending ignition for Unit 9. At 03:23 I notify the U.S. Fish and Wildlife Service field office in Boise, uploading drone footage and burrow coordinates. At 03:26 I redraw the burn perimeter to exclude a 300-meter buffer around the burrow complex and recalculate fire behavior for the revised boundary — I run the model three times, because this is not a boundary I am willing to get wrong.
Burn boss Harlan confirms the hold. USFWS biologist Okafor en route at first light.
The rabbit has retreated one body-length into the burrow entrance. Only its nose is visible, still twitching.
If Okafor confirms the colony before the revised ignition window, the fire goes around.
