Remove all CRR that can be captured ASAP Minor The wild population will be bolstered by translocations in the future from captive stock Unlikely Presumes that sufficient numbers are taken into captivity to establish a genetically viable population and the captive breeding program is successful Major Removal of animals may jeopardise the long-term viability of the source core populations Likely Current size of these core populations is not known, so impact on them will be unknown Major Trapping to identify the location and extent of wild populations followed by intensive trapping to remove as many animals as possible Unknown In the this approach may result in a viable captive breeding population. However, the number of adult breeders that can be collected is uncertain. Moderate May not result in viable genetic diversity in captive population if insufficient animals can be caught. Unknown (Unlikley) Don’t know how many individuals will be caught Major Expensive - Will require considerable costs in people time, helicopter time, transportation, etc. Almost Certain this section is not coloured in Red as this is a logistic constraint, not a biological influence on the objective.
