Gall y matiau rwystro golau neu suddo a mygu cynefinoedd gwely\u2019r m\u00f4r, gan effeithio ar y bywyd morol a allai fod wedi denu deifwyr SCUBA a snorcelwyr i ymweld.

Gall y gwymon hyn olchi i fyny ar draethau, yn aml mewn symiau mawr iawn, lle gallant bydru, gan ryddhau arogleuon annymunol neu niweidiol. Gall rhywogaethau estron goresgynnol hefyd greu amodau annymunol a hyd yn oed peryglus i ddefnyddwyr hamdden.
