Number of unauthorized actions and persistent structures by agencies, organizations, or individuals that manipulate plants, animals, pathogens, soil, water, or fire is a required measure under the unauthorized actions indicator. The unauthorized actions indicator is under the trammeling actions inside wilderness monitoring question for untrammeled quality.

This measure is reported as a single value for report year.

The table below shows reported unauthorized actions trends at each USFS wilderness using this measure. As ever, selected measures have filled grey circle, and colors indicate an upward, stable, or downward reported trend. Unselected measures can also be recorded, and are shown as hollow circles in the appropriate color.
