Information on the features to be protected in a system of conservation reserves is an obvious requirement. The quality of the data base will primarily determine the effectiveness of conservation planning in protecting the full range of natural features in a region. However, the way in which data are used to make decisions on the locations of protected areas is also critical. Rigorous procedures for reserve selection can make the difference between achieving reservation goals or not. Research on reserve selection in New South Wales over recent years has concerned both data bases and procedures for guiding decisions. Reserve planning in many regions is based largely on some form of land classification like vegetation types or land systems. There are good reasons for using such land classes to guide the selection of reserves and to judge their representativeness. Nevertheless, they can have considerable limitations as a basis for protecting all the species in a region. These limitations are reviewed with references to more detailed discussions of particular issues. The paper also reviews a variety of procedures for selecting reserves which have been tested and applied in New South Wales. Some of the recent procedures are conceptually simple but very useful in identifying the requirements of reservation goals and demonstrating the options available to planners for representing particular features. Three principles are proposed which should underpin any attempt at systematic conservation planning.

Breeding Seasons

The dietary items fed to regent honeyeater, Xanthomyza phrygia, nestlings and fledglings by adults were recorded in two consecutive breeding seasons in the Bundarra–Barraba region west of Armidale, New South Wales. Insects were the most common dietary items fed to juveniles (53% of identified items), followed by lerp (26.5%) and nectar (20.5%). Nestlings were fed mostly insects (58% of feeds), and carbohydrates (nectar and lerp) made up the rest of their diet. Fledglings, however, were fed mainly carbohydrates (nectar and lerp comprised 61.2% of all items) while protein from insects was the other major component of their diet. Males tended to feed juveniles more insects than did females, although there were no significant divisions of labour between parents in selecting dietary items for nestlings or fledglings. This study highlights the importance of insects and lerp in the diet of juvenile regent honeyeaters, and the diversity of plant species on which their parents foraged. The species shows a broader resource selection than was found in previous studies which considered the species to be highly nectarivorous and selective for a few key eucalypt species. The importance of insects and carbohydrates other than nectar in the diet of the regent honeyeater needs to be recognised in the development of conservation strategies for the species.

Abstract Rotherham, D., Broadhurst, M. K., Gray, C. A., and Johnson, D. D. 2008. Developing a beam trawl for sampling estuarine fish and crustaceans: assessment of a codend cover and effects of different sizes of mesh in the body and codend. – ICES Journal of Marine Science, 65: 687–696. An experiment was carried out in the Clarence River (New South Wales, Australia) to test the hypotheses that fish and crustacean catches in an experimental beam trawl were affected by a codend cover and the sizes of mesh in the body and codend. The cover had no obvious effects on the catches retained in the codend. Similarly, in comparisons between trawl bodies made from 26- and 41-mm diamond-shaped mesh, there were no differences in the assemblages of fish caught, or in the mean numbers entering the codends. For one species of fish (Acanthopagrus australis), however, there were differences in the proportions caught between the trawl bodies across different size classes. There was also some evidence to suggest that mesh size in the body of the trawl influenced the size selection of school prawns (Metapenaeus macleayi). For most finfish, there were no differences in catches between codends made from 20-mm and from 29-mm mesh hung on the bar (i.e. square-shaped mesh). In contrast, mesh size in the codend was important for the size selectivity of school prawns, with smaller carapace lengths at 50% retention in the 20-mm codend. We conclude that use of a 41-mm mesh in the body and a 20-mm square mesh in the codend of the beam trawl would be appropriate for future sampling with this gear in estuaries of New South Wales. A similar experimental approach to ours is needed in adapting the beam trawl to estuaries in other parts of the world, or in developing other types of research trawl.

I studied the selection of breeding habitat and nest microhabitat in Scarlet Robins Petroica multicolor and Eastern Yellow Robins Eopsaltria australis, in remnant woodland on the New England Tablelands of New South Wales in 2000?2002. Yellow Robins used breeding territories (n = 10) with significantly higher densities of rough-barked saplings, acacias and other (non-Acacia) shrubs than Scarlet Robin breeding territories (n = 10) and plots lacking Yellow Robins (n = 7). Yellow Robins nested mostly in gully and lower-slope positions, with a southerly aspect, >40 m from the woodland edge, whereas Scarlet Robins nested mostly on upper slopes and ridges, with no preferred minimum distance from the woodland edge. Most Yellow Robin nests (86% of 58) had overhead foliage within 1 m, shielding them from above, whereas over half (58% of 54) of Scarlet Robin nests were in unconcealed positions. Yellow Robin nests had significantly greater density of cover, and the surrounding habitat was more complex, than for Scarlet Robin nests, in 0.13-ha plots centred on the nest. Breeding success and fledgling survival in the Yellow Robin were positively related to the density of acacias, non-Acacia shrubs and rough-barked saplings (but not gum saplings) in breeding territories. Fledging success and juvenile survival in the Yellow Robin were also positively related to habitat complexity around nest-sites (but not distance to nearest cover, or items of cover within 20 m). Scarlet Robins had exposed nests and suffered high nest predation, with too few successful nests for comparison with unsuccessful nests. Habitat conservation for the Yellow Robin should address the complexity of the ground, shrub and sapling layer in woodland remnants; that for the Scarlet Robin may need to address foraging substrate and ecologically based control of nest predators.

State Records

During a joint field trip organised by H. Streimann in 1999, the authors collected large amount of bryophytes in Queensland, New South Wales, and Victoria states and in the Austral Capital Territory (A.C.T.). Some of them proved to be new state records, or new records for Australia. The list below is the first selection of these records in Hepaticae, with 16 species newly reported from the whole continent.

Relative palatability of 12 previously selected taxa of Eragrostis curvula complex was assessed using a visual rating scale of 0 (not grazed) to 10 (completely grazed). Visual ratings were converted to ranks and the most and least palatable lines were compared over 19 grazing assessments in trials at Wagga Wagga, Temora and Orange, New South Wales. Three highly palatable and 2 acceptably palatable accessions were identified. The importance of palatability in the E. curvula complex is discussed.

Observations were made of the foraging behaviour of the feathertail glider (Acrobates pygmaeus) at Waratah Creek in south-eastern New South Wales (NSW). Gliders were observed on 164 occasions, including 42 observations of feeding, 41 observations of moving along a substrate and 68 observations of gliding to a tree, an understorey plant or to the ground. On the remaining occasions, gliders were lost from view before any information was recorded. Most (91%) feeding observations occurred in live eucalypts. When feeding in eucalypts, 61% of observations were of gliders searching under loose shedding bark and 32% were of gliders engaged in foliage gleaning. Foraging amongst loose bark is suggested to represent feeding on honeydew and arthropods while foliage gleaning is indicative of gliders engaged in feeding on manna, honeydew, lerps and arthropods. Nectar feeding was uncommon and only 3% of trees in which gliders were observed were flowering. In contrast, 42% of these trees showed signs of recent bark shed. Two observations were of gliders foraging on the ground, suggesting that arthropods may also be captured there. Comparison of the frequency of use of different tree species with the abundance of those species showed a highly significant preference for E. fastigata, while other species were used in proportion to their abundance. Analysis also showed that gliders used trees in the smallest of three size classes (<40 cm diameter at breast height) less often than expected on the basis of the abundance of these trees. Overall, gliders used the six different habitat types in the study area in proportion to their abundance but showed significant seasonal differences in the use of these habitats. These results permit consideration of the management requirements of the feathertail glider in the timber production forests of NSW. It is concluded that the requirements of this species are catered for by existing management prescriptions.

Austrelater, gen, nov., is proposed for three new species, A. macphersonensisfrom New South Wales and southern Queensland, A. peckorum from North Queensland and A. howensis from Lord Howe Island. The reared larva of Austrelater macphersonensis, gen. et sp. nov., is described and figured. The phylogenetic relationships of the genus are discussed and a selection of adult and larval characters used in the cladistic analysis are discussed. The subfamily Lissominae is redefined to include Oestodes, Austrelater, Sphaenelater, Protelater and those taxa (Lissomus, Drapetes) formerly included in the Lissominae (usually in Throscidae or as Lissomidae).
