Certain rootless plant species such as common bladderwort (Utricularia vulgaris) and coontail (Ceratophyllum demersum), seem to thrive in the presence of starry stonewort (Nitellopsis obtusa) and benefit from the sediment nutrient release caused by starry stonewort.

In its introduced range, starry stonewort (Nitellopsis obtusa) peaks in biomass in late fall/early winter after much of the other local vegetation has subsided. Thus, starry stonewort (Nitellopsis obtusa) could provide an important source of food and habitat for overwintering species.
