Studies of six riparian communities in the Czech Republic indicated that ornamental jewelweed (Impatiens glandulifera) has a negligible effect on existing communities and therefore is not a threat to plant diversity there.

Due to its genetic variation, ornamental jewelweed (Impatiens glandulifera) has the ability to adapt to local environments within a few generations and has a strong probability of expanding northward into previously unoccupied niches.

Ornamental jewelweed (Impatiens glandulifera) also seems to react positively to increases in carbon dioxide and temperature. With increasing global mean temperature, I. glandulifera could expand its range northward by several degrees latitude.
