  • Cordgrass (Spartina spp.) is recognized as a highly invasive plant in estuaries throughout the world because of remarkable versatility and resiliency, significant reproduction, strong adaptability, rapid spreading, and vigorous growth. In this review, therefore, to provide insights on the effective management practices, the previous research works were summarized and discussed. Spartina spp. is a perennial halophyte, warm-season (C4) grass that reproduces both sexually through seeds and asexually by rhizomes. Management strategies for cordgrass have included various physical, biological, and chemical controls. Herbicides are usually the most cost-effective means of control. Currently, glyphosate, imazapyr, fluazifop and haloxyfop have been practically used. To improve the control efficacy, a combination of two more than methods (example, mowing-spraying) is needed to be applied consistently every year for at least 3 to 4 years and to be sprayed with enough dry time (>4-6 hr) at an early growth stage (before flowering). Consistently repeated application of same herbicide have to be avoided to prevent an unexpected emergence of herbicide-resistant lines. On the other hand, Spartina spp. have many positive functions for agricultural and eco-engineering purposes. Thus, we have to give more intensive research for effectively managing advantages and disadvantages of Spartina plantations.

  • We have found the plants belonging to the genus Spartina which has not yet been reported for the flora of Korea. This has been distributed at Dongmak seashore in Ganghwado since 2012. These were identified as common cordgrass (Spartina anglica C. E. Hubb.) belonging to the family Poaceae, the genus Spartina. It is a perennial halophyte as an alien weed that can grow in the tidal flat, native to southern England. Here, we named it for 'Young-guk-Gaet-ggeun-pool' in Korean refer the origin, reported the distribution, spreading condition, and botanical characteristics of common cordgrass. In China, Spartina anglica was introduced in 1963, it was approved that it had benefit in a bioengineering side firstly. But it was known that as a highly invasive plant to make a monotype meadow of Spartina anglica which has deteriorate the ecological function of saltmarsh. And also it has another problem that is not easy to eradicate. The spreading of Spartina anglica which was appeared in the West coast of Korea may threaten severely to the domestic mudflat and estuary ecosystem. For the maintenance of mudflat ecosystem soundly, continuous monitoring and active eradication plans are required.
