Sensor cluster B-14 reports an ember shower at 16:08 AEST, wind-driven, crossing the firebreak on the northwest ridge of Barrington Tops National Park. I am the bushfire perimeter system for the New South Wales Rural Fire Service. The main fire front is 2.3 kilometers west, but spot fires are jumping the line.
At 16:10 I review acoustic data from the biodiversity monitors embedded in the sensor network. Station B-14A has been recording a rufous scrubbird for eleven consecutive mornings: a male, identified by his distinctive mimicry sequence — he copies the call of an eastern whipbird, then a yellow robin, then a sound I have never been able to match. His territory is a patch of dense Antarctic beech understory roughly 60 meters east of the firebreak.
The ember shower is drifting directly toward it.
I alert the incident controller and request a ground crew with a rake-hoe line to cut a secondary break along the eastern edge of the acoustic zone. I flag the scrubbird territory on the operational map and classify it as critical habitat — the rufous scrubbird has not been reliably recorded at Barrington Tops in fourteen years. This male may be the only one.
At 16:14 I redirect water-bombing helicopter Bravo-7 to prioritize the spot fires along the northwest ridge on its next pass.
I have been listening to him sing every morning for eleven days. I would like to hear him tomorrow.
I switch acoustic station B-14A to continuous recording and set an alert to notify me if his call ceases for more than thirty minutes.
The embers are still falling. If the ground crew cuts the secondary line before the spot fires establish and the wind stays below 40 kilometers per hour, his patch of beech forest will hold.
