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.

Reserve System

REGARDLESS of the merits and values of individual national parks and nature reserves, Australia's conservation reserves do not ensure the survival of the continent's biota. There are many reasons for this. Reserves, even the largest, are too small and vulnerable to broad area disturbance. Consider that, in January 2003, fires burnt more than two-thirds of Kosciuszko National Park, which at 690 000 ha is the largest park in New South Wales and one of the largest in Australia. This shows how even the largest conservation reserves are at risk of catastrophic disturbance. The much smaller Nadgee Nature Reserve (21 000 ha) in southeastern New South Wales has burnt almost in its entirety twice in the 35 years I have worked there. The Nadgee fires and those in Kosciuszko were started by lightning and were the result of prolonged drought, events common across the continent. When small size is coupled with isolation, the long-term survival of populations and the exchange of propagules within the reserve system becomes problematical. Small size and isolation do not leave much scope for plants and animals to adapt to long-term climate change, either through dispersal or by evolution. Even reserving 10 or 15% of land for nature conservation, as recommended by some international conservation agencies, will be inadequate; a target of 30% would have better ecological credentials, but even this could prove inadequate unless the nature conservation reserve system was designed to allow for long-term evolutionary change, which it is not (see Archer 2002; Recher 2002a,b).

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.
