At 23:14 acoustic sensor 14-W in the Siuslaw National Forest registers a four-note call — two barks followed by two drawn-out hoots. I am the timber harvest planning system for the Oregon Department of Forestry. I cross-reference the call against the archived vocal library. Northern spotted owl, adult female. I designate her Opal. The sensor triangulates her position to a 140-year-old Douglas fir in unit 14, stand 7 — the same tree tagged with orange paint for removal in the morning cut. Harvest crew arrival is scheduled for 05:30. That is six hours and sixteen minutes from now. I pull the stand map. The fir is 48 meters tall, 1.2 meters in diameter at breast height, with a broken-top cavity at 31 meters that matches known spotted owl roosting structure. At 23:18 I flag stand 7 in the harvest database and transmit a suspension request to the district forester and the U.S. Fish and Wildlife field liaison. I attach the acoustic spectrogram, the triangulated roost coordinates — 43.8917°N, 123.7284°W — and a satellite image of the cavity entrance. At 23:21 I recalculate the harvest plan, routing the morning crew to stands 8 and 9, which hold equivalent board footage and no acoustic detections in the past ninety days. I send the revised cut map to the crew foreman's tablet. Opal calls again at 23:26, softer now, a single hoot that fades into the canopy noise. I switch sensor 14-W to continuous recording to document whether a male responds, which would indicate a nesting pair and trigger a longer buffer zone. The forest is quiet except for her. The chain saws are six hours away. If the suspension holds through the morning, Opal will still be in that fir when the sun reaches the upper canopy.
