## In authors' words

### What they found (results)

Over 123 years at the Fernow Experimental Forest, stream nitrogen losses remained elevated for approximately a decade after atmospheric nitrogen deposition returned to baseline, with a critical threshold near 16 kg N/ha/yr determining watershed nitrogen export.

## Commentary

### In short

The study examines how a watershed functions as an integrated system whose long-term outputs depend on historical inputs and a threshold governing nitrogen release.
