Ecology

Species of the section ''Spartina'' are used as food plants by the larvae of some Lepidoptera species including the Aaron's skipper, which feeds exclusively on smooth cordgrass, and the engrailed moth. Some species of the section ''Spartina'' are considered as ecosystem engineers that can strongly influence the physical and biological environment.Li, B. et al (2009) ''Spartina alterniflora'' invasions in the Yangtze River estuary, China: An overview of current status and ecosystem effects, Ecol. Eng. 35: 511-520.Balke, T. et al (2012) Conditional outcome of ecosystem engineering: A case study on tussocks of the salt marsh pioneer ''Spartina anglica'', Geomorphology 153-154: 232-238. This is particularly important in areas where invasive ''Spartina'' species significantly alter their new environment, with impacts to native plants and animals.Strong, D.R., & Ayres, D.R. (2013) Ecological and Evolutionary Misadventures of ''Spartina'', Annu. Rev. Ecol. Evol. Syst. 44:389-410.

, ''Sporobolus anglica'', also known as English cordgrass, is an aggressive, aquatic alien that invades mud flats, salt marshes and beaches, out-competing native plants, spreading quickly over mud flats and leaving large ''Spartina'' meadows. It is also invasive in China and California. ''Sporobolus montevidensis'' and ''Sporobolus pumilus'' have become invasive on the Iberian Peninsula and the west coast of the United StatesD. G.

. Various members of the genus (especially ''Sporobolus alterniflorus'' and its derivatives, ''Sporobolus anglicus'' and ''Sporobolus × townsendii'') have spread outside of their native boundaries and become invasive. Big cordgrass (''S. cynosuroides'') is used in the construction of bull's eye targets for sports archery. A properly constructed target can stop an arrow safely without damage to the arrowhead as it lodges in the target.
