Population justification: The population was estimated to number 5,000-10,000 individuals by Rosenberg (1990), and repeat surveys on Santa Cruz Island in 2000 gave broadly similar results. This roughly equates to 3,300-6,700 mature individuals.

Trend justification: The species is undergoing a slow decline. The rate of decline was extrapolated from a decline in detections of 9% (c.f. 1986-1987 surveys) during 2000 surveys on Santa Cruz (Gibbs et al. 2003). By 2007, the decline was steeper (Shriver et al. 2011). Therefore, the population decline is here tentatively placed in the band 1-19% over ten years.
