Population justification: The estimate of 930-1,300 mature individuals (roughly equivalent to 1,400-2,000 individuals in total) was estimated based on 712 calling males found within 66% of the suitable habitat within its known range. |
|
Trend justification: This species's population is suspected to be in decline owing to the continued loss and degradation of its habitat for residential, industrial and recreational development, amongst other related and unrelated threats. |
