Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2007-10-23
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.
Justification:
This is a common species within suitable habitat and the population status is thought to be stable. There are no major threats although there are some localized declines due to coastal development and mechanical damage. This species is listed as Least Concern.

Habitat and Ecology [top]

Habitat and Ecology:Along the Pacific coast of North America, this species grows in the upper intertidal zone (+1.5 m to mean lower low water) (Green and Short 2003). Phyllospadix spp. grow on rocky substrates in regions with high wave exposure (Hemminga and Duarte 2000).
Systems:Marine
Generation Length (years):6

Threats [top]

Major Threat(s): There are no major threats to this species. Localized threats include coastal development and modifications and over-water structures in the form of ferry terminals, commercial docks. Mechanical damage from boats and dredging is also a minor localized threat.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures for this species. It is not clear if the federal, provincial or state, or local administrative laws and ordinances recognize this species in the Northeast Pacific (Green and Short 2003).
