Population justification: Garnett et al. (2011) estimate a declining population of between 2,500 and 10,000 mature individuals, roughly equivalent to 3,750-15,000 individuals in total. |
|
Trend justification: Over consecutive atlases the number of 10 minute grid cells from which the species was recorded decreased from 164 in 1977-1981 to 142 in 1998-2003 and 90 in 2003-2008 (J. O'Connor in litt. 2008). Habitat was cleared at 5% per annum in the late 1990s and early 2000s (Wilson et al. 2002). Other parts of the range may have avoided such rapid land conversion but overall a moderately rapid decline is estimated. |
