Population justification: There is no recent information on population size. Gardner-by-Española is a tiny island, a few hectares in size, and is less than 1 km from Española, so the population there may not represent a discrete subpopulation. The total population is thought to number 1,000-2,499 individuals, equating to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.

Trend justification: There is insufficient information on this species to extrapolate a population trend.
