It is readily eaten by nutria and may need protection from them. Uniola paniculata requires high beaches and dunes. Populations decreased in abundance along the Louisiana coast as soils became wetter. Ecotypes from Louisiana performed better along our coast than material from other localities. The species produces by vegetative and sexual means.
Vegetative reproduction involves layering.
As stems become heavier and lodge into the water or on moist soils new plants develop at the nodes. The plants provides excellent cover on spoil banks and on levees where they grow into open water. Its high stem densities are effective at reducing wave and water erosion and for high sediment capture.
