The diets of the two small scincid lizards Lampropholis guichenoti and L. delicata were examined by analysis of gut contents. The study was conducted in Mumbulla State Forest on the south coast of New South Wales. Gut samples were collected before an intense fire in November 1980, then again in December of 1980, 1981, 1983 and 1984. The study included a period of intense drought from 1980 to 1983. Both species were found to be generalist feeders taking a wide range of invertebrate taxa, mostly insects and spiders. The range of taxa taken as prey indicated that both species foraged over a variety of substrates and were flexible in their foraging behaviour. Both species had a similar diet, except during the drought years when there were significant differences in the proportions of some taxa eaten. That both species are common in the coastal forests near Bega and survived the combined impact of fire and drought can be attributed, at least in part, to the flexibility of their foraging ecology.

The roosting and foraging ecology of the golden-tipped bat (Kerivoula papuensis) was studied by radio-tracking on the south coast of New South Wales. Despite a previous scarcity of records, 16 bats were harp-trapped during spring and summer, of which 11 were radio-tracked. Roost types (n = 33 roosts over 48 roost days) were the suspended nests of yellow-throated scrubwrens (Sericornis citreogularis) (50%), nests of brown gerygone (Gerygone mouki) (27%), beneath hanging moss on tree trunks (21%) and in foliage (2%). All roosts were located in rainforest and close to creek lines (mean = 6 m). Yellow-throated scrubwren nests were more common in rainforest on small, first- and second-order streams (4.6 nests km–1 – 5.2 km searched) than on larger, third-order streams (1.1 nests km–1 – 2.7 km searched). Colonies were small (<10 bats) and usually comprised a mix of sexes. Maternity roosts in summer were located in both yellow-throated scrubwren nests (n = 8) and brown gerygone nests (n = 3). Foraging bats were recorded flying a maximum of 2.1 km and were regularly recorded (43% of monitored time) on upper slopes away from rainforest. Plots (5 × 5 m) were used to compare prey densities (small web-building spiders) between rainforest and sclerophyll forest and different topographies (creeks, riparian vegetation and upper slopes). Although spider numbers were patchy, upper-slope sclerophyll forest supported the greatest number of spiders, the number being significantly greater in upper-sclerophyll forest than in sclerophyll creeks and rainforest on upper slopes. A forward step-wise multiple regression showed that spider numbers per plot were positively related to the density of understorey stems. Management implications from this research are that riparian rainforest provides the key roosting habitat for K. papuensis. Recent management prescriptions in New South Wales' forests available for logging have correctly targeted the protection of this environment. However, the extent of foraging in sclerophyll forest on upper slopes was previously unknown. Attention needs to be given to management actions that maintain a mosaic of dense patches of understorey on upper slopes, where the numbers of web-building spiders are high. Further research is required to determine the effectiveness of using buffered protection zones within logged areas for K. papuensis.

The association of an armoured scale insect (a diaspidid) with dieback of a population of a native cycad (Macrozamia communis L.A.S.Johnson) was investigated on the south coast of New South Wales. The diaspidid was found to be undescribed but morphologically similar to oleander scale – here we call it Aspidiotus cf. nerii. It is probably native to Australasia and its current known distribution is within Murramarang National Park (MNP). Aspidiotus cf. nerii has been abundant on symptomatic M. communis at MNP over at least the past decade and has spread to new parts of the park. In population studies of infested and uninfested areas we found that, although both areas had populations with reverse J curves showing dominance of seedlings, mortality of seedlings and caulescent plants was significantly higher in infested sites. Infested areas had been burnt less frequently than uninfested areas. Fire does not appear to eradicate the diaspidid but may reduce its effects enough for plants to recover. We recommend further research into the use of fire as a management tool. Although other factors may be contributing to the severity of the dieback, we suggest there is sufficient evidence for the diaspidid to be regarded as the primary cause of dieback in M. communis in MNP, regardless of its origin. Given the occurrence of similar diaspidids on cultivated plants in botanic gardens, translocation of threatened Macrozamia species using plants grown in nurseries should be undertaken with extreme caution.

The performances of Hunter River and introduced varieties of lucerne were tested at Milton (south coast of N.S.W.). There were no significant differences in yield between any variety in spring or summer, but Hairy Peruvian, African, and Indian produced significantly more than Hunter River in winter. These introduced varieties could make a valuable contribution to the dairying industry of the south coast of N.S.W.

ABSTRACT Aubrey Elliott (1910–1943), a passionate ‘bird-man’, lived in the suburb of Tapitallee on the south coast of New South Wales until 1940. During that period he and his brother, Arthur kept notes on the birds in the local area and devised a hide that was mounted on a utility that enabled them to take close-up photographs. To augment his observations Elliott interviewed local residents and collated information on the status of the area’s birds. In 1985 I purchased the property next to where Elliott lived and was given access to his notes. This paper presents a comparison of avifauna in the Tapitallee area between 1926–40 and 1985–2020. During that time there have been changes in the distribution and abundance of many birds. Fourteen species have become locally extinct while 28 have colonised/recolonised the area. Combining Aubrey’s and our data a total of 194 species of bird have been recorded in the area. Dams have been constructed and native vegetation has regrown on the steeper slopes. These actions have expanded the habitat for aquatic and forest dependant species but disadvantaged those that occupy grasslands. The Red Fox Vulpes vulpes colonised the area in 1907 and is implicated in the local extinction of the Bush Stone Curlew Burhinus grallarius. Wildfire in January 2020 burnt a relatively small portion of the Tapitallee area but these fires burnt an extensive area of southern NSW and Victoria. These fires were likely to be responsible for the decline in the numbers of Yellow-faced Honeyeaters Caligavis chrysops and White-naped Honeyeater Melithreptus lunatus migrating north in the autumn of that year.
