142 For non-endemic taxa, please consider only the New Zealand populations when answering the questions below (please also answer the questions for endemic taxa): Is the taxon extinct in the wild, but surviving in captivity or cultivation? Yes / No Will the status of the taxon deteriorate if current species specific management ceases? Yes / No Is the taxon sufficiently well-known to meaningfully answer the questions below? Yes / No (if no, then stop here) Population: Is the total population size 5000 mature individuals unknown? Please provide more accurate estimate if possible: ........................................................ Is the total area occupied 100 ha (1 km 2 ) unknown? Please provide more accurate estimate if possible: ........................................................ Is the taxon subject to extreme unnatural population fluctuations, or natural fluctuations overlaying human-induced declines, such that the fluctuation increases the threat of extinction? Yes / No Sub-populations: Do the data available for your assessment of the questions below allow Confident response for the taxon throughout its range Confident response for many but not all sub-populations Confident response for only a small subset of sub-populations Low confidence in all estimates? Is the known number of sub-populations of the taxon 2 3-5 6-15 >15? Please provide more accurate estimate if possible: ........................................................
Is the taxon found at only one location, so that a single event (e.g., a predator irruption) could soon affect all individuals of the taxon? Yes / No Is the number of mature individuals in the largest known sub-population 500 unknown? Decline: Regardless of whether or not the trend is the result of management, is the total population now showing a sustained recovery stable in decline? If in decline, do existing threats mean the decline in the total population in the next 10 years is predicted to be >80% 60-80% 30-60% 5-30% Not applicable? Is this decline predicted to continue beyond the next 10 years? Yes / No / Not Applicable In the period since 2001/02, has the species changed: in total population by ..................................................................................................... in area occupied by ........................................................................................................ in number of existing populations by ............................................................................. What is the likely cause of this change (above)?............................................................ ......................................................................................................................................... ......................................................................................................................................... ......................................................................................................................................... ......................................................................................................................................... Is recruitment failure 1 likely to result in catastrophic declines in the future? Yes / No 1 Current population may appear stable but the age structure is such that catastrophic declines are likely in the future (Molloy et al. 2002). 143
