GREATER BROAD-NOSED BAT SCOTEANAX RUEPPELLII<br />
EPBC Act: Not Listed TSC Act: Vulnerable Priority in Area: Low<br />
Occurrence in the Survey Area<br />
This species has only once been recorded in JKCR (Herr<br />
2000 a,b), where a single individual was trapped at the<br />
old camp on the <strong>Jenolan</strong> River. No individuals were<br />
trapped during the current survey despite a large amount<br />
<strong>of</strong> trapping effort. Ultrasonic call is not a reliable way <strong>of</strong><br />
identifying this species (Pennay et al. 2004). Further<br />
information from trapped individuals is required before its<br />
status can be adequately assessed for the reserve.<br />
Regional <strong>Conservation</strong> Significance<br />

<strong>The</strong> greater broad-nosed bat is primarily a coastal<br />
species, particularly in the southern part <strong>of</strong> its range<br />
(Wilson 2006). Within the region, there are recent<br />
records from the Illawarra coastal plain (G. Daly pers. comm.), Towra Point NR (Schulz 2006) and<br />
Royal NP (DECCW 2011). It is also found within the Blue Mountains, with individuals trapped at<br />
Gardens <strong>of</strong> Stone NP (OEH 2011b). Across the region, modelling predicted this species where there<br />
was higher fertility soils, including the Boyd Plateau and Bindook Highlands. However, there are still<br />
considerable gaps in our knowledge <strong>of</strong> this species, with this compounded by confusion with the<br />
morphologically similar eastern false pipistrelle and unreliable ultrasonic call identification, and there<br />
remains conjecture over its actual habitat preferences. Should a sizable population be confirmed<br />
within JKCR it should be elevated to a high conservation priority.<br />
Threats in the Survey Area<br />
Key threats include predation by cats and foxes, inappropriate fire regimes, competition for hollows<br />
with feral honeybees and loss <strong>of</strong> hollow-bearing trees. Within JKCR none <strong>of</strong> these threats are likely to<br />
be seriously impacting at present. Climate change has also been predicted to seriously impact this<br />
species (Wilson preliminary data).<br />
Management Considerations<br />
No management considerations at present but should a significant population be confirmed in the<br />
future, the following may be important:<br />
Continue fox and cat control.<br />
Retention <strong>of</strong> hollow-bearing trees.<br />
