A pervasive invasive species has rooted near Cold Stream at a point where it enters the Cedar River and has progressively moved upstream. This species thrives in the disturbed portion of the riparian buffer that has been cleared in the past few years due to increased construction activity near the stream. additional disturbance was brough about from the toppling of overstory trees near the stream caused by a Derecho (a wind event producing sustained straight line winds). These openings have allowed the propagation of the species presented below.
