Fall is a great time to scout for invasive plants because they stay green longer than native species.
As the leaves drop, patches of persistent, incongruous green foliage may be noticed in woods or along trails, raising a red flag.

This contrasting green should raise a red flag.
Fortunately, this makes invasive species easy to spot and manage.
