Management Considerations<br />
Protect known nest trees, including during hazard<br />
reduction burning operations.<br />
If rabbit baiting is to be considered, assess and<br />
take steps to minimise impacts on the little eagle.<br />
Occurrence in the Survey Area<br />
Status uncertain. One confirmed record from McKeowns Valley<br />
from the current survey program (February 2011). <strong>The</strong>re are no<br />
previous records <strong>of</strong> this species. However it is difficult to<br />
distinguish from a number <strong>of</strong> other raptors, such as the whistling<br />
kite, and could easily have been overlooked or misidentified in the<br />
past. It is not known if this species nests within the park.<br />
Regional <strong>Conservation</strong> Significance<br />
<strong>The</strong> range <strong>of</strong> this species may have extended in south-eastern<br />
Australia following the introduction and expansion <strong>of</strong> the rabbit<br />
(Marchant and Higgins 1993). However, there was a 14 per cent<br />
decrease in the reporting rate <strong>of</strong> this bird between 1984 and 2002<br />
across the nation (Barrett et al. 2003). This species is scattered<br />
across the Sydney Basin Bioregion in small numbers, with the<br />
majority <strong>of</strong> sightings in woodlands <strong>of</strong>ten adjacent to open areas<br />
on near-coastal plains and foothills. Since the predominant<br />
dietary item is the rabbit (Marchant and Higgins 1993), this<br />
species is likely to be more prevalent within the reserve for a<br />
period <strong>of</strong> years following wildfire and other disturbance events<br />
when rabbit numbers are higher and then gradually diminish in<br />
numbers as rabbit populations decline. As there is only a single<br />
record for the reserve it is not currently possible to ascertain the<br />
importance <strong>of</strong> the reserve to the regional conservation <strong>of</strong> the<br />
species.<br />
Threats in the Survey Area<br />
Habitat destruction, including the removal <strong>of</strong> nest trees which may<br />
be used in successive or subsequent years (Marchant and<br />
Higgins 1993); the loss <strong>of</strong> nest trees through fire; and secondary<br />
poisoning from rabbit baiting.<br />
