Scientific Name: Lithophyllum amplostratum
Species Authority: W.R.Taylor

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2007
Date Assessed: 2007-03-01
Assessor(s): Miller, K.A., Garske, L. & Edgar, G.
Reviewer(s): Stuart, S.N. & Carpenter, K.E. (Global Marine Species Assessment Coordinating Team)
Justification:
Coralline species in the Galápagos are in urgent need of reassessment. Recorded from the type locality only, nothing is known about population size, trends, range or threats. Currently assessed as Data Deficient.

Geographic Range [top]

Range Description: Lithophyllum amplostratum is an endemic species to the Galápagos Islands, only known from its type locality at Black Beach Anchorage, Floreana (Taylor 1945). There are no records since the type collection.

Population [top]

Population: According to Taylor (1945), L. amplostratum was occasionally present at Black Beach Anchorage, Floreana. However there is no recent information on distribution or trends for this species.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: L. amplostratum was reported to occur in intertidal pools, forming clumps of several centimeters diameter (Taylor 1945).
Systems: Marine

Threats [top]

Major Threat(s): Presumably El Niño and climate change. Ecosystem interactions involving these two factors appear to have caused widespread decline in algal populations because of an increase in density of grazing sea urchins and other herbivores, following overexploitation of predators along with ENSO disturbances.

Conservation Actions [top]

Conservation Actions: Type locality within Galápagos Marine Reserve (IUCN category VI); Galápagos Archipelago Particularly Sensitive Sea Area (PSSA); Galápagos Island World Heritage Site (UNESCO N (i)(ii)(iii)(iv)), and Galápagos Island Man and Biosphere Reserve (UNESCO).
