Population justification: The total population was recently estimated at c.2,500-3,800 individuals, thus the number of mature individuals is precautionarily estimated to be in the range 1,000-2,499.
Trend justification: This species is suspected to be declining rapidly owing to the considerable threats from beachfront development, the salt industry and squatters within its restricted coastal habitat.
