4 – The extent and adequacy of monitoring for Australian threatened bird species^49thornbill Acanthiza pusilla archibaldi – should be monitored as a matter of urgency
even if listed as less threatened under the EPBC Act because they are endemic to
Australia.
The difference between those taxa with no monitoring and those with some
suggests that inaccessibility discourages any monitoring at some sites whereas
detectability affects quality of monitoring, not whether it will actually occur – a
taxon that is hard to find may still be monitored but not very well. Variability has
little effect on either monitoring occurrence or quality, probably because, of the
