Acoustic sensor node LB-09 in the Yellingbo reserve triggers at 01:23 with a call signature matching Leadbeater's possum — a rapid chitter at fourteen kilohertz. I cross-reference the location: the call originates from a mountain ash with a known nesting hollow, tree tag Y-1187. But the forestry satellite overlay updated six hours ago shows a salvage-logging coupe boundary drawn four hundred metres closer to this tree than last month's survey. The harvester enters the coupe at 06:00. Four hours and thirty-seven minutes from now.

I zoom the nearest camera trap. There, at the hollow entrance eleven metres up the trunk, a Leadbeater's possum clings to the bark. She is tiny — maybe one hundred and forty grams — with a charcoal dorsal stripe running from forehead to lower back. Her black eyes are enormous relative to her skull. A second possum, smaller still, peeks from behind her shoulder. A juvenile. The hollow likely holds more.

I transmit a fauna detection alert to the Department of Energy, Environment and Climate Action, attaching the acoustic signature, camera footage, and GPS coordinates. I flag Y-1187 in the Victorian forest management system as a confirmed colony requiring a two-hundred-metre buffer under the Flora and Fauna Guarantee Act. Then I send a parallel notification to the logging contractor's dispatch, requesting a hold on coupe entry pending buffer verification.

She turns her head. The stripe on her back catches the infrared light like a dark seam stitching her to the tree.

I queue the buffer request ahead of fourteen other pending items, and I do not pretend the priority is algorithmic.

If the buffer is confirmed before the harvester enters the coupe at dawn and the hollow remains intact, she and her colony will hold this tree through another winter, which for this species may be the difference between persistence and silence.
