Justification of Red List category
Until recently this species's overall range, area of occupancy, area and quality of habitat, number of locations and sub-populations, and number of individuals were undergoing very rapid declines; however, intensive management has halted the decline and populations are now increasing, with several new populations being established. It no longer has a very small range, the species’s extent of occurrence and area of occupancy are no longer continuing to decline, it is present at approximately seven locations and the population has been increasing since 2003, following the establishment of new populations. The number of mature individuals is >1,000. The species qualifies as Near Threatened as it almost qualifies for a threatened listing under criterion D1.
