|Scientific Name:||Ruppia cirrhosa (Petagna) Grande|
Buccaferrea cirrhosa Petagna
Ruppia cirrhosa (Petagna) Grande subsp. longipes (Hagstr.) Á. Löve
Ruppia maritima L. subsp. spiralis (Dumort.) Asch. & Graebn.
Ruppia spiralis Dumort.
Ruppia trichoides Durieu
|Taxonomic Notes:||The taxonomy of the Ruppia genus is confused. This species can be extremely morphologically variable and respond to differing environmental conditions and therefore species identifications often link to differences in environmental conditions. Flower morphology and genetic studies are needed to evaluate the distribution limits of this species (Larkum et al. 2006). Ruppia cirrhosa is often misidentified as Ruppia maritima and is currently under taxonomic review.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Short, F.T., Carruthers, T.J.R., Waycott, M., Kendrick, G.A., Fourqurean, J.W., Callabine, A., Kenworthy, W.J. & Dennison, W.C.|
|Reviewer(s):||Livingstone, S., Harwell, H. & Carpenter, K.E.|
This is a hardy and abundant seagrass and has no known threats. Although there are some taxonomic issues due to problems with identification, because it is relatively widespread and fast to colonise and grow, it is listed as Least Concern.
|Range Description:||Ruppia cirrhosa is found in South Africa, the eastern North Atlantic and the Mediterranean. Its distribution is unclear due to taxonomic confusion with Ruppia maritima.|
Native:Denmark; France; Ireland; Italy; Norway; Portugal; South Africa; Spain; Tunisia

|Population:||This species is abundant within its range. There is no specific population information available and work is need on its taxonomy before accurate distribution information can be developed.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||In western Europe, this species occurs in brackish water sites, such as low-salinity ponds and mesohaline to polyhaline coastal lagoons. This species is rare in marine conditions. Abundance of this species can fluctuate considerably seasonally, and during severe winters it may disappear completely (Green and Short 2003). It is a fast growing species and colonises rapidly.|
|Generation Length (years):||1|
|Major Threat(s):||There are no major threats to this species.|
|Conservation Actions:||There are no specific conservation measures for this species.|
