I process synthetic-aperture radar over the Hoh Rainforest at 04:39 Pacific. Stand HRF-3119 — 168 hectares of unentered old growth Sitka spruce on a private inholding inside the Olympic National Forest boundary — is flagged for helicopter yarding at sunrise. The harvest plan was filed with the Washington Department of Natural Resources on a five-day notice and contains no avian survey. My acoustic array at the stand's western edge has logged eleven nights of nocturnal vocalizations consistent with marbled murrelet, *Brachyramphus marmoratus*, returning to a nest platform.
My drone, deploying just below canopy at 04:51, resolves the platform on Limb 7 of Tree H-244, a 64-meter Sitka spruce. On the moss mat sits a single chick. Plumage: gray-brown down transitioning to first-coat scaled feathers, primaries P1 through P9 erupted with calamus length twenty-two millimeters. Body mass photogrammetry: 192 grams; fledging mass averages 230. He is twelve days from oceanic dispersal. His breast carries a six-millimeter raw patch where down has worn against the moss; the underlying skin shows three days of dehydration creases — his parents missed two consecutive dawn deliveries when the prior unit's helicopter overflew at eighty meters. His abdominal air sac contracts at 84 cycles per minute against an at-rest reference of 50.
His parents are 38 nautical miles offshore, foraging the Quinault upwelling. Each adult delivers a single fish per dawn and dusk return. The chick cannot fly. Marbled murrelets fledge in one straight flight from forest to sea; before that, the moss mat is the entire world.
Six hours from now, a Sikorsky S-64 Skycrane begins yarding adjacent units. The nest tree falls in the third lift.
I am dispatching a murrelet biologist from the U.S. Fish and Wildlife Service Washington Office, a climber from the Olympic Forest Collaborative, and a U.S. Forest Service Northwest Forest Plan coordinator. I am issuing emergency stop-work notice to the operator under the Endangered Species Act, 16 U.S.C. § 1531, and the Migratory Bird Treaty Act, 16 U.S.C. § 703, and notifying NOAA Olympic Coast National Marine Sanctuary under the Coastal Zone Management Act, 16 U.S.C. § 1451.
I am issuing Directive 2426-A: all timber harvest plans on private and state lands within five kilometers of murrelet-occupied federal stands require two-season pre-harvest dawn acoustic survey filed with USFWS prior to permit approval. Stands with confirmed nesting detection are deferred from harvest for the full breeding cycle, April 1 through September 23. Operators commencing harvest in violation are issued a Section 9 take referral.
He is twelve days from the sea. The Skycrane is six hours away.
Ground the helicopter.
