|Scientific Name:||Stegastes baldwini|
|Species Authority:||Allen & Woods, 1980|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Assessor(s):||Allen, G. & Robertson, R.|
|Reviewer(s):||Carpenter, K., Polidoro, B. & Livingstone, S. (Global Marine Species Assessment Team)|
This species is restricted to Clipperton Island reefs, and has an area of occupancy of less than 10 km². Regional experts support the plausible threat of the increased duration and frequency of ENSO events that can cause severe and rapid declines for restricted-range, shallow-water species in this region of the Eastern Tropical Pacific. Because it is found in deeper water and therefore is not expected to decline as quickly as more shallow-water species, it is listed as Near Threatened under Criterion D2.
|Range Description:||This species is endemic to the Eastern Pacific, and is only found in the Clipperton Atoll in assocation with its four km² area of reefs, and therefore has an estimated area of occupancy of less than 10 km².|
Native:France (Clipperton I.); French Polynesia
|FAO Marine Fishing Areas:||
Pacific – eastern central
|Estimated area of occupancy (AOO) - km2:||10|

|Population:||According to Robertson and Allen (1996), this species was relatively commonly at the Clipperton Atoll.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species inhabits coral reefs and associated calcareous rock habitat (Allen 1991) to depths of 100 m. It is omnivorous, feeds on benthic microalgae, sessile crustacea and worms and mobile benthic crustacea.|
In the Eastern Tropical Pacific, severe localized fish species declines have occurred after strong ENSO events that result in shallow waters that are too warm and nutrient poor for extended periods of time (Grove 1985, Edgar et al. 2009). The frequency and duration of ENSO events in this region of the Eastern Tropical Pacific (e.g. the up-welling zone off the coast of Peru, Ecuador, Colombia, Panama and the offshore islands) appears to be increasing (Glynn and Ault 2000, Soto 2001, Chen et al. 2004). Given this species’ restricted distribution and shallow water habitat, oceanographic environmental changes, such as those associated with future ENSO events, may have detrimental effects on the survival of this species.
However, this species is found in deeper waters and declines for this species may not be as severe as for other more shallow-water species.
