No information is available on population size or trends, and there is little information on area of occupancy. More data are needed to assess threat status, hence listed as Data Deficient.

Current Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: G. smithii is an intertidal species, occurring from the high intertidal to low intertidal (Taylor 1945, CDRS record 2002).
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. As an intertidal species, is likely to be vulnerable to anomalous prolonged warming events, such as El Niño event.

Conservation Actions [top]

Conservation Actions: G. smithii occurs within the 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).
