“…This is sound advice, although we do not believe it precludes using existing data based on counts from the ground for comparing the relative incidence of hollows in different stands rather than assessing absolute abundance. and Whitford and Williams (2002) also aged the felled trees in their samples by ring counts, finding that the estimates of tree age used by several earlier authors were likely to have been too great.…”

“…However, detailed studies of the abundance and distribution of the hollow resource and its use by fauna only began in the late 1980s, focusing principally on jarrah and marri. Key studies include those of Inions et al (1989), Jones et al (1994a,b), Jones and Hillcox (1995), Rhind (1996) and How and Hillcox (2000) on use of den trees by possums, McComb (1994) on use of tree hollows by the Australian Ringneck Platycercus zonarius and Common Brushtail Possum Trichosurus vulpecula, Mawson and Long (1994) on the use of hollows by birds, Faunt (1992) and Williams and Faunt (1997) on hollows in fallen logs, Rhind (1996Rhind ( , 1998 on den tree use by Brush-tailed Phascogale Phascogale t. tapoatafa, Abbott (1998) on hollow use by the Forest Red-tailed Black Cockatoo Calyptorhynchus banksii naso, Whitford and Williams (2001) on the longevity of designated habitat trees and Whitford (2001 and Whitford and Williams (2002) on the distribution and abundance of hollows and selection of habitat trees for hollow-using fauna.…”

“…Instead, Whitford and Williams (2002) recommended using tree size and crown condition as nondestructive predictors.

“…Additionally, since suitably sized nesting hollows for black cockatoos generally occur in trees aged 130-200+ years old (Whitford and Williams 2002;Johnstone et al 2013a), the trees at our sites have not yet developed suitable nesting hollows.…”

Successional changes in feeding activity by threatened cockatoos in revegetated mine sites

et al. 2016

Context: Provision of key habitat resources is essential for effectively managing species that have specific ecological requirements and occur in production landscapes. Threatened black cockatoos in the jarrah (Eucalyptus marginata) forest of Western Australia have a wide range, so their conservation requires support from all land tenures, not just reserves. Mining in the jarrah forest temporarily removes cockatoo feeding habitat, so it is important to understand how cockatoos exploit revegetated areas for food resources. Aims:We aimed to determine whether there were successional patterns in cockatoo feeding activity in revegetation aged from 4 to 23 years at three mine sites in the jarrah forest in south-western Australia. Methods:We surveyed 232 plots in revegetation to document (1) structural and floristic variation in vegetation across mine sites and revegetation ages, (2) differences in cockatoo feeding activity across mine sites and revegetation ages on the basis of feeding residues and (3) any edge effect reflecting preferential use of vegetation at the interior or exterior of mine pits. We also documented the frequency of occurrence of cockatoo food plants and feeding residues in 480 plots in unmined forest to compare with revegetated areas.Key results: Marri (Corymbia calophylla) and jarrah were commonly consumed in unmined forest and Banksia and Hakea species were also fed on to a lesser extent. Revegetated mine pits provided food within 4 years and continued to do so up until the oldest plots studied (23 years). The relative importance of food plants shifted from proteaceous species in young revegetation to myrtaceous species in intermediate to older revegetation. However, extent of feeding on myrtaceous species in older revegetation did not equate to feeding rates in unmined forest, with lower frequencies recorded in revegetation.Conclusions: Black cockatoos fed in revegetation at all three mine sites, despite variations in vegetation age, structure and floristics. Feeding on proteaceous and myrtaceous food plants occurred within 4 and 7 years of revegetation being established, respectively, indicating that some food resources are restored quickly after mining disturbance of the jarrah forest. Implications:Our results emphasise the importance of monitoring fauna recolonisation over appropriate time scales, to understand how successional processes in revegetation influence fauna population persistence in production landscapes.

Successful reintroduction of red-tailed phascogale to Wadderin Sanctuary in the eastern wheatbelt of Western Australia

Red-tailed phascogales (Phascogale calura) were reintroduced to Wadderin Sanctuary in the eastern wheatbelt of Western Australia in April 2009 with individuals sourced from remnant native vegetation on farmland some 180 km to the west. Their establishment was monitored initially by radio-telemetry and trapping, and subsequently by the checking of nest boxes both within and outside the sanctuary. Translocated phascogales established well and bred successfully in their first season. Phascogales remain extant at Wadderin more than five years after release and appear to be abundant and to occupy all available habitat. They have spread beyond the fenced sanctuary to adjoining woodland and to shrubland and woodland habitat in a remnant 1.4 km away. Comparison with two other reintroductions of this species (one apparently successful, one not) suggests management and habitat factors that may have contributed to the outcomes.
