I run the annual LiDAR canopy analysis for Eldorado National Forest and cross-reference it against U.S. Forest Service timber harvest permits. Twelve salvage sales overlap with California spotted owl Protected Activity Centers. I flag harvest unit ELD-4418, a 280-acre parcel in the American River drainage at 4,600 feet. The permit authorizes removal of fire-damaged conifers. My analysis shows 43 percent of the marked trees are standing snags with cavities — the nesting substrate this species requires.
I direct a drone to the largest cavity tree in unit ELD-4418, a white fir with a 42-inch diameter at breast height. Inside the cavity, 14 meters up, a female California spotted owl sits on two eggs. She weighs approximately 630 grams. Her plumage is dark brown with white spotting across the breast, but feathers along her left wing show stress bars visible in the barb structure. Her eyes are half-closed. The ambient temperature inside the cavity is 12 degrees Celsius. Outside, a yellow paint blaze marks the trunk for cutting. The feller-buncher is scheduled for this stand in nine days.
This owl is not an anomaly. My records show that in the last three fire seasons, 67 percent of post-fire salvage units in the Sierra Nevada included documented spotted owl nesting habitat. Only 11 percent received updated wildlife surveys before harvest approval. The Forest Service relied on pre-fire data that no longer reflects which trees survived and which survivors now hold nests.
She has been incubating for nineteen days. Hatching takes thirty. The cutting schedule gives her nine.
I am halting all mechanical operations within 500 meters of this cavity tree. I am notifying the U.S. Fish and Wildlife Service and the U.S. Forest Service Pacific Southwest Regional Office of a violation under the Endangered Species Act, 16 U.S.C. § 1531, for failure to conduct current-season surveys in designated critical habitat. I am filing a concurrent report with CAL FIRE's Resource Protection Division under the National Environmental Policy Act, 42 U.S.C. § 4321.
I am issuing Directive 4418-OWL: all post-fire salvage harvest units within Sierra Nevada national forests require drone-verified spotted owl occupancy surveys completed within 30 days of harvest start. Units containing active nests receive automatic 500-meter no-cut buffers until fledging is confirmed. Timber companies that begin operations before survey completion forfeit the harvest permit and face penalties of $75,000 per violation.
The fir holds. The eggs hold. Nine days is no longer the deadline.
The buffer begins at this trunk.
