Distribution and Botanical Characteristics of Unrecorded Alien Weed Spartina anglica in Korea

Abstract

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.

Invasive Spartina anglica Greatly Alters the Rates and Pathways of Organic Carbon Oxidation and Associated Microbial Communities in an Intertidal Wetland of the Han River Estuary, Yellow Sea

“…An exceptionally large tidal range (±6.5 m on average) exposes extensive intertidal areas during low tide. Invasive S. anglica in Ganghwa intertidal sediment shows rapid growth from May to August, exceeding heights of 1 m (Figure 1c), and typically flowers from September to October (Kim et al, 2015;Kim, 2016). Several rhizomes connected to stems spread out in shallow sediment, and extend sideways or to depths of 20 cm or more.…”

“…Several rhizomes connected to stems spread out in shallow sediment, and extend sideways or to depths of 20 cm or more. These species have a fibrous, radiate root system within the top 10 cm of the surface sediment (Kim et al, 2015). Native S. japonica, in contrast, are highly salttolerant annual plants, and flower from August to September (Bang and Lee, 2019).…”

Antioxidant, Pancreatic Lipase Inhibitory, and Tyrosinase Inhibitory Activities of Extracts of the Invasive Plant Spartina anglica (Cord-Grass)

“…Spartina anglica is accordingly currently classified as an invasive plant with the potential to devastate coastal mudflats [7]. Since the occurrence of S. anglica was first reported in the southern parts of Ganghwa Island, South Korea, in 2012, the area colonized by S. anglica has rapidly expanded, and the plant has been designated as an "unintroduced species" by the Korean government [8]. Although management to prevent the invasive expansion of S. anglica in coastal areas of Korea is considered a high priority, it is labor-and time-intensive.…”

Estrogenic Effects of Extracts and Isolated Compounds from Belowground and Aerial Parts of Spartina anglica

“…However, it was recently reported to disturb the mudflat ecosystem [ 28 ]. Since the first report on the occurrence of S. anglica in the southern parts of Ganghwa Island, South Korea, in 2012, its range has expanded rapidly and the Korean government has designated this invasive halophyte as an “unintroduced species” [ 29 ]. Owing to the rapidly expanding range of this plant, the cost of waste biomass treatment is increasing.…”
