The Distribution of Arboreal Marsupials in Relation to Eucalypt Forest Types in the Eden (Nsw) Woodchip Concession Area.

Abstract

Data collected during clear felling are collated and presented on the distribution of arboreal marsupials in 16 forest vegetation types (FVT) in 7 FVT groups. Eight species were included in the study: Petaurus breviceps, P. australis, P. norfolcensis, Petauroides volans, Acrobates pygmaeus, Trichosurus vulpecula, Pseudocheirus peregrinus and Cercartetus nanus. Most of the individuals reported were in the following 6 FVTs: swamp gum (characterized by Eucalyptus ovata); mountain gum (E. dalrympleana)/manna gum (E. viminalis); peppermint (E. radiata or E. dives); southern blue gum (E. maidenii, E. cypellocarpa or E. nitens); brown barrel (E. fastigata); and brown barrel/gum (E. cypellocarpa, E. nitens, E. maidenii, E. viminalis or E. dalrympleana). The results are discussed in relation to present forest management and forest clearing procedures in the Eden region. Forests about to be cleared for Pinus radiata plantations or for farmland on private property adjacent to State Forests are predominantly of types identified as of high value as wildlife habitat.

Regional habitat selection of large gliding possums at forest stand and landscape scales in southern Queensland, Australia

“…Error lines represent the 95% confidence interval for the regression between predicted vs. the observed observations. tall moist eucalypt forests when compared with low elevation, dry sclerophyll forest types (Braithwaite et al, 1988;Bennett et al, 1991;Kavanagh and Bamkin, 1995;Goldingay and Daly, 1997;Kavanagh and Stanton, 2005). This has often been explained as a preference for forests containing higher foliar nutrients as determined by the distribution of the soil parent material (Braithwaite et al, , 1984Pausas et al, 1995;Recher et al, 1996).…”

“…However, they are known to favour particular floristic and/or structural mixes over others for general habitat use (Kavanagh, 1984;Braithwaite et al, 1988;Bennett et al, 1991;Kavanagh and Wheeler, 2004). In southern Queensland, greater gliders were detected in a wide range of forest types but were most common in the high elevation tall moist eucalypt forests (classes B, J and S).…”

Extinction in Eden: identifying the role of climate change in the decline of the koala in south-eastern NSW

“…Records of koalas that had gone into care were also obtained from the Wildlife Information and Rescue Service (WIRES) and Native Animal Network Australia (NANA) rehabilitation-group databases and via direct interviews with local convenors. Published scientific studies that were reviewed for koala records include Braithwaite (1983), Braithwaite et al (1988), Lunney and Leary (1988), Lunney and Moon (1988), Cork et al (1990), , Jurskis (2001), Jurskis et al (2001) and Lunney et al (1997).…”

Reversed sexual dimorphism and altered prey base: the effect on sooty owl (Tyto tenebricosa tenebricosa) diet

“…Its diet, therefore, varies significantly spatially and temporally (Kavanagh 1997;Bilney et al 2006) due to differing prey availability and the susceptibility of the prey to predation (Braithwaite et al 1988;Bennett et al 1991;Catling and Burt 1995;Menkhorst 1995). This was highlighted by the marked seasonal dietary changes that often corresponded to breeding cycles of some main prey species, indicating increased susceptibility to predation during these times.…”
