Vegetation was mapped using existing maps, Landsat interpretation, aerial photograph interpretation and some verification by ground surveys. Twenty-five moss cushions were collected to identify pollen rain and pollen indicators of vegetation for use in fossil pollen interpretation. Eucalyptus (10%), Poaceae (4-10%), Casuarina (4-5%), Asteraceae (Tubuliflorae) (0-4%) and Cyperaceae (0-2%) were the general components in the pollen rain of the region. Subtropical rain forest was characterized by Backhousia and low values of a wide range of taxa. Cool temperate rain forest had Nothofagus values above 40% and Eucalyptus values below 20%. Subalpine grasslands had Poaceae values above 45%, Eucalyptus values below 15% and small quantities of Epacridaceae and Goodeniaceae pollen. Subalpine forest and wet eucalypt forest formations had very similar pollen representation and could be confused in pollen spectra. However, Monotoca, Banksia, Leptospermum pollen and fern spores were more common in the wet eucalypt forests. Dry eucalypt formations were characterized by 2-20% values of Bursaria, Callitris and Dodonaea as well as eucalypt values.

Pollen Distribution

The modern pollen spectra for Eucalyptus forest and rainforest communities were investigated from 19 sites in the Robertson area on the Central Tablelands of New South Wales. Cluster and discriminant analyses were applied to analyse pollen distribution from within and from outside warm temperate rainforest stands and tall open eucalypt forest stands. Pollen abundance is compared with a number of plant abundance estimates of taxa within forests to study pollen representation at the forest scale. Pollen of Doryphora, Polyosma, Pittosporum, Hymenanthera, Tasmannia, Asclepiadaceae and most rainforest taxa investigated are poorly represented, while sclerophyll and open-ground taxa, particularly Eucalyptus, are better represented. The pollen of many native taxa do not appear to be well dispersed, and local pollen is commonly outweighed by pollen from regional sources. Pollen representation varied between taxa and sites, with factors such as vegetation structure, plant distribution, topography and disturbance influencing pollen representation.

The Impact

Hollows in trees are recognized as a critical and threatened resource for a wide range of fauna in Australian forests and woodlands, yet little data are available on the impact of fire on hollow-bearing trees. We report an opportunistic, post-fire assessment of the proportion of burnt, hollow-bearing trees that collapsed in stands near roads following low intensity prescription burns in three areas of mixed eucalypt forest in the Pilliga forests. Mean collapse rates on 29 plots (40 by 50m), separated by burn Area, ranged from 14?26% for a total of 329 burnt hollow-bearing trees. Collapse rates on individual plots ranged from 0?50%. Collapsed, hollow-bearing trees were predominantly older, with 40% of senescent trees and 44% of live stags collapsing. The best predictor in models of tree collapse was the presence of a basal fire entry point. We cannot determine the extent to which collapse rates on our plots are representative of burnt areas away from containment roads due to sampling limitations, but they appear to be higher than those reported from wildfire and more intense prescription burns in southern Australia. Our results point to an urgent need for comprehensively designed studies to address the impacts of prescribed burns on hollow-bearing trees.

ABSTRACT In Australia’s eucalypt forests and woodlands, co-habiting birds differ in the foraging manoeuvres or methods used to search for and take prey, the substrates and plants on which prey are found, and the heights at which foraging takes place. On the Southern Tablelands of New South Wales, eucalypt forest and woodland birds foraged on different substrates between study plots, seasons, and years. As a result, the proportions of foraging manoeuvres differed in space and time as different foraging methods were used to obtain food from different substrates. Of the 32 species tested for the summer of 1980/81, 24 foraged differently between one or more of the three plots studied. In winter, nine of 15 species on two plots foraged differently between plots. Differences in foraging were found between seasons and/or years for 20 species, including when data from individual plots were combined to test for differences in foraging between summer and winter. Of 70 comparisons of foraging behaviour for individual plots, that is, excluding combined plot data, 50 differed between seasons and/or years. Significant spatial and temporal differences in foraging were recorded for all foraging guilds. Bark and foliage foragers differed most frequently between pairs of plots in all seasons and years, with aerial foragers showing the fewest differences. Between seasons and years differences were greatest among ground-foragers and foliage-foragers where respectively 76% and 80% of intraspecies comparisons on individual plots differed. The differences were the result of temporal and spatial differences in the types and abundances of foraging substrates and the prey available to foraging birds. Each species has its own unique requirements and management targeted at one or a few species will disadvantage others. Consequently temporal and spatial habitat heterogeneity is necessary for the conservation of avian biodiversity.

Abstract A description is provided for Arthonia ilicina, which is frequently found on living and dead bark of smooth-barked trees, usually but perhaps not invariably in regions with a moist climate. Some information on its associated organisms and substrata, habitat, dispersal and transmission, and conservation status is given, along with details of its geographical distribution (Africa (South Africa), North America (Canada (British Columbia, Newfoundland), USA (Alaska, California, Florida, Louisiana, Minnesota, Oregon, Washington)), South America (Argentina, Ecuador, Chile), Asia (Taiwan), Atlantic Ocean (Portugal (Azores, Madeira), Spain (Canary Islands)), Australasia (Australia (New South Wales, South Australia, Tasmania, Victoria, Western Australia)), Caribbean (Cuba), Europe (Denmark, France, Germany, Ireland, Italy, Norway, Portugal, Spain, Ukraine, UK)). This species is routinely used in the British Isles as an indicator when making ecological assessments, and specifically as an indicator of ecological continuity, particularly in the west of Ireland and the west of Scotland, and of oceanic and temperate rain forest.

Mammal surveys were carried out on the Carrai Plateau and Richmond Range in north-east New South Wales between March 1988 and November 1989. The emphasis was placed on rainforest mammals, following the recognition by Adam ( 1987) that the species lists of mammals in the state's rainforests were incomplete and that more research was needed. The mammals were surveyed primarily by analysis of prey remains in Dog and Fox scats, collected from roads throughout the forests, and from bat trapping. The bat fauna at both the Carrai Plateau and Richmond Range is rich (1 0 species and nine species respectively, including the rare Golden-tipped Bat, Kerivoula papuensis, in the Richmond Range). Scat analysis revealed the presence of 24 native species on the Carrai Plateau, and on the Richmond Range there were 17 species, including high numbers of two pademelon species. Feral prey species are almost completely absent, although the Fox is an established predator in both areas. A sharp division was identified between the mammal faunas of closed and open forests. Differences were found also between the mammal fauna composition of the two rainforest sites, and with those of nearby eucalypt forests. The mammal fauna of New South Wales rainforests is distinct from open forests and future mammal surveys are needed to ensure an adequate level of knowledge to identify and conserve these areas.

Block Sizes

Pattern analysis data are presented for a number of tree species populations sampled from two sites located in dry sclerophyll forest within the Ku-ring-gai Chase park of New South Wales. The distributions proved to be predominantly contagious or random, with regularity occurring only occasionally. Observed variations in the degree of aggregation exhibited by a species were taken into account in interpreting pattern analysis curves. The relation of pattern analysis data to sample quadrat data fitted to known mathematical models is extremely variable, and it is shown that pattern at block sizes other than the one under consideration may suppress the appearance of deviations from randomness at block sizes which do show contagion when sampled with randomly placed quadrats. The possible origins of contagious distributions in eucalypt forest are briefly discussed.

Statistical models are presented of the distribution and abundance of ground-dwelling mammals in eucalypt forests in relation to environmental variables within an area of approximately 24 000 km2 in north-eastern New South Wales. Environmental variables are defined as climatic or topographic variables that may be useful to map the distribution of fauna. The environmental variables examined were season, temperature, rainfall, elevation, lithology, steepness of slope, position on slope, aspect and landform profile. The probability of recording some species was higher in spring than autumn and many species were in highest abundance in areas of low temperature (high elevation). Although aspect was a significant variable in a number of models, no species was absent from any aspect category. Mid-slopes down to and including creeks and drainage lines were particularly important for many species, as were areas with flatter terrain. Although we have modelled environmental variables only there will no doubt be longer-term interactions between habitat and environmental variables. Fundamentally, environmental variables will determine the type of habitat present at a site, and the distribution of canopy communities, at least, can be predicted from environmental variables. However, other studies have shown for ground-dwelling mammals that environmental variables contribute little and it is the state of the habitat locally, and particularly the understorey, that determines their presence and abundance at a site. The results are discussed in relation to similar models using habitat variables and in relation to the use of such models in the management of ground-dwelling fauna in forests.

Clover Pasture

Merino ewes were grazed for 10 years at stocking rates of 8, 12 and 16 ha-1, lambing in winter, spring or summer on a phalaris/white clover pasture on the Northern Tablelands of New South Wales. Wool production, wool yield and count, and lambing and weaning rates were established for the wide range of climatic conditions experienced. A spring lambing is indicated under the within-year price relationships experienced. Under a wide range of wool and lamb prices the optimum stocking rate varied from 12 to 16 ewes ha-1 depending on labour costs.
