Not Native
Deep in the woods we discover the mother of all invasive barberries surrounded by little ones.
If you are overseeing a species forest look first on the old logging roads. They will be heavily infected with invasive plants which crowd out native plants. It is our job to defend the native plants by killing the invasives. Not difficult to do, however, it is not particularly fun.
There is a native barberry in North America, but this is an invasive barberry inadvertently brought in by illegal loggers clearing a way into the forest over fifteen years ago. Among other things, logging (1) brings in invasive plants, (2) encourages thick briars and undergrowth, (3) selectively removes native trees and thus altering the native equilibrium, (4) destroys the forest canopy, (5) introduced disease and (6) causes deer populations to surge.
At this very moment the Supreme Court of the United States of America will determine if a logging road is "'point sources' of water pollution requiring industrial discharge permits typically applied to factories and sewage plants . . ."

If you look closely at the picture here you will see grass in the foreground. Grass sometimes grows in the deep woods when the forest canopy is absent. Besides invasives, ruts and stumps, grass also indicates a logging road was used here some years ago.
