The population is approximately 500-1,500 adult pairs (Gasc et al. 1997; Arnold 2003). There are approximately 25, mostly isolated, populations. The total population is slowly increasing following coordinated recovery efforts, following a long period of decline and near extinction. The current increase, which probably started around the time that the first re-introductions were made in 1989, has been maintained even during years of drought, notably in 1999-2000. The population trend in this species is monitored through annual tadpole counts, the counts for 2004 (over 30,000 tadpoles) being the highest on record. The increase in numbers in established populations is not dependent upon continued re-introductions. However, it is unlikely that new populations would be established without re-introductions.
