Abstract:

An autumn fuel-reduction burn of low intensity (200-250 kW m-1) was performed in a Eucalyptus obliqua forest near Gembrook, Victoria. The aim of the study was to evaluate the effect of a single burn on floristics, biomass, N content and N2 fixation. The fire burnt 50% of the area in a mosaic pattern, significantly reducing understorey vegetation cover (by 90%) and plant density (by 70%) in burnt areas immediately after the fire. Understorey cover was restored to 40% of the original value 1 year later, but 33% of the understorey species were still absent from burnt areas. In the whole site mosaic, biomass declined by 30 t ha-1 (3 kg m-2) (10%) and N content by 100 kg ha-1 (10 g m-2) (18% excluding soil N, 2% including soil N). These losses were due to significant losses of biomass and N from the understorey only (88%, 85%), standing dead trees (57%, 62%), fallen wood (73%, 60%) and litter (69%, 70%). One year later, there was no significant increase in either biomass or N content. Burnt areas had five times the total nitrogenase activity of unburnt areas, owing to significantly greater specific nitrogenase (C2H2 reduction) activity, three times the nodule weight and 20 times the plant density of unburnt areas for the dominant legume (Pultenaea scabra). Using a calibration ratio for C2H2:N2 of 2.68 :1 derived from glasshouse growth studies, N2 fixation for P. scabra was estimated as 15 g ha-1 year-1 in burnt areas and 3 g ha-1 year-1 in unburnt areas, with a mean of 9 g ha-1 year-' for the whole site mosaic. Adding superphosphate to burnt areas increased estimated N2 fixation significantly by 14%, mainly by increasing nodulation. Losses of N due to the burn (100 kg ha-1) were considerably greater than gains from increases in N2 fixation (6 g ha-1 year-1) one year after the burn. Even allowing for N2 fixation by other, infrequent legumes and greater N2 fixation in subsequent years, these data suggest that the N lost in the burn is more likely to be replaced by inputs from soil reserves and rainwater than from N2 fixation by legumes.

Full text

Abstract:

Acrobates pygmaeus was captured in nestboxes in three areas of central and southern Victoria: the Gembrook-Cockatoo area and Nar Nar Goon North east of Melbourne, and Daylesford north-west of Melbourne. Breeding was strictly seasonal and females produced two litters between July and February each year. Males also showed seasonal fluctuation in testes sizes. Mean litter size was 3.5 at birth and 2.5 at weaning. Pouch life lasted 65 days and young were weaned at approximately 100 days of age. Growth was slow and maternal investment in each young was high, and continued after weaning. Most individuals matured in the season following their birth, but some males did not mature until the second season after their birth. Maximum field longevity was at least three years. Comparisons are made with other small diprotodont marsupials.

Abstract:

McArthur's Fire Danger Indices were developed originally as empirical models to describe fire danger in dry sclerophyll forest and grasslands of Australia. These indices are now used widely in southeastern Australia for fire danger rating and as a guideline for the issue of fire weather warnings. Nine years of historical fire reports, fire danger indices and meteorological information have been analysed objectively to develop a model to predict days of high fire activity in the mallee shrubland of northwestern Victoria. Tested on two years of independent data it was found that the use of a simple model utilising standard meteorological observations rather than the McArthur Forest Fire Danger Index reduced the false alarm rate from 98.4% to 96.7%. Although apparently a small reduction in false alarm rate, over a two year period days of high fire activity predicted incorrectly were reduced dramatically by 345 days.

Abstract:

Natural forests have many ecological, economic and other values, and sustaining them is a challenge for policy makers and forest managers. Conventional approaches to forest management such as those based on maximum sustained yield principles disregard fundamental tenets of ecological sustainability and often fail. Here we describe the failure of a highly regulated approach to forest management focused on intensive wood production in the mountain ash forests of Victoria, Australia. Poor past management led to overcutting with timber yields too high to be sustainable and failing to account for uncertainties. Ongoing logging will have negative impacts on biodiversity and water production, alter fire regimes, and generate economic losses. This means there are few options to diversify forest management. The only ecologically and economically viable option is to cease logging mountain ash forests altogether and transition wood production to plantations located elsewhere in the state of Victoria. We outline general lessons for diversifying land management from our case study.

Full text

Abstract:

The pool of carbon in the world's forests is of similar magnitude to that in the atmosphere, yet little attention has been given to improving measures of carbon in terrestrial biomass. Much of the critical data for forest biomass on which models of global carbon cycling rely is, in fact, based on the accurate sampling of less than 100 ha of forest. Uncertainties in biomass estimation at the local and regional level may be responsible for much of the current speculation as to unidentified sinks for carbon. We have used a forest inventory (i.e. records of forest volume obtained for harvesting purposes) approach to quantify the biomass of forests in Victoria, Australia. Forests were analysed by type, age and region. Regression equations were developed for the accumulation of biomass with age across all productivity classes for each forest type. The mean carbon density for above-ground components of Victorian native forests is 157 tonnes ha-1 (t ha-1), although forest types range in mean carbon density from 250 to 18 t ha-1. Pinus radiata D. Don plantations in Victoria have a mean carbon density of 91 t ha-1 in the above-ground components. Total carbon stored in above-ground biomass is estimated to be 1.2 X 109 t. Rates of carbon fixation vary with forest age, species and site. Mountain ash (Eucalyptus regnans F. Muell.) forests fix around 9 t of carbon ha-1 annually during the first few years of growth, decreasing to 6 t ha-1 by age 10. Rates of carbon accumulation by other forests are generally less than this and, at the lower end of the range, box-ironbark forests, mallee and woodlands accumulate between 0.5 and 2 t ha-1 year-1. P. radiata plantations in Victoria will accumulate around 7 t carbon ha-1 year-1.

Full text

Abstract:

A population of Rattus fuscipes, in Sherbrooke Forest, Victoria, had a well defined breeding season. Mating occurred between November and January and the young were born between December and February. Juveniles were first captured in late February at approximately 1.5 months of age. The subadult age class displaced the parental age class in the population by the following August, so that almost all animals breeding in a season belonged to a single age class. The degree of home range overlap changed seasonally and could be related to changes in the proportion of amicable and agonistic behaviour judged from a series of contrived laboratory encounters. Diet consisted of both plant and insect material and changes in the proportion of these two components correlated with changes in survival. Measurements of 15 physiological parameters and organ weights, drawn at montly intervals indicated three periods during the life cycle when R. fuscipes exhibited heightened adreno-cortical activity. It is suggested that the development of territoriality in subadults during late autumn and possibly the decrease in abundance and quality of food in early winter, largely determine the size of the breeding population in late spring.

Full text

Abstract:

Habitat use, diet and behaviour of adult and immature crimson rosellas were compared in the non-breeding season in a wet sclerophyll forest in southern Victoria. Immature birds occurred mainly at forest edges and were more patchily distributed than adults. They also differed quantitatively in their diet, spent more time feeding and less time resting, and occurred in larger flocks than adults. It is suggested that these dietary and behavioural differences probably result from either enforced use of inferior habitats and food resources, or less efficient foraging.

Full text

Abstract:

Bryophytic communities in plateau forests of mature Eucalyptus regnans are distributed according to substrate type and microclimate, whereas those in gully rainforests are more catholic. Objective classification of releves indicated the extent to which groupings are shared between these major topographic sites and the degree to which their distribution is mediated by differences in microclimate. Communities on many substrates in E. regnans forests are either seral to a fern floor 'climax' or exhibit pattern and process cycles of regenerative stability.

Full text

Abstract:

A total of 1487 observations of nine species of arboreal mammal, Acrobates pygmaeus, Phascolarctos cinereus, Petauroides volans, Petaurus australis, P. breviceps, P. norfolcensis, Pseudocheirusperegrinus, Trichosurus caninus and T. vulpecula, were made during surveys of the vertebrate fauna of northeastern Victoria. Habitat use by each species was examined in relation to eight forest types that occur along an environmental gradient ranging from sites at high elevation with a high annual rainfall, to sites on the dry inland and riverine plains. Arboreal mammals were not evenly distributed between forest types. Three species (P. australis, P. volans and T. caninus) were mainly associated with moist tall forests; two species (P. norfolcensis and T. vulpecula) were primarily associated with drier forests and woodlands of the foothills; the remaining three species (A. pygmaeus, P. breviceps and P. peregrinus) occurred widely throughout the forests. The composition of the arboreal mammal assemblage changed along the environmental gradient, but species displayed gradual changes in abundance with forest type rather than marked discontinuities in distributional pattern. The highest overall frequencies of occurrence of arboreal mammals were in forests typically dominated by a mixture of eucalypt species. The position at first sighting of an animal, and the relative height in the forest stratum, were used to describe the micro-habitats utilised. In general, the microhabitats occupied by each species are consistent with the distribution of their known food resources.

Abstract:

Forests exhibit thresholds in disturbance intervals that influence sustainability of production and natural values including sawlog production, species existence and habitat attributes. Fire is a key disturbance agent in temperate forests and frequency of fire is increasing, threatening sustainability of these forest values. We used mechanistically diverse, theoretical fire interval distributions for mountain ash forest in Victoria, Australia, in the recent past and future to estimate the probability of realising: (i) minimum sawlog harvesting rotation time; (ii) canopy species maturation; and (iii) adequate habitat hollows for fauna. The likelihood of realising fire intervals exceeding these key stand age thresholds diminishes markedly for the future fire regime compared with the recent past. For example, we estimate that only one in five future fire intervals will be sufficiently long (~80 years) to grow sawlogs in this forest type, and that the probability of forests developing adequate habitat hollows (~180 years) could be as low as 0.03 (3% of fire intervals). Therefore, there is a need to rethink where sawlogs can be sourced sustainably, such as from fast-growing plantations that can be harvested and then regrown rapidly, and to reserve large areas of existing 80-year-old forest from timber harvesting.

Full text

Abstract:

Pseudomys novaehollandiae is ‘Endangered’ in Victoria, where it is presently considered to be extant at only three localities Loch Sport, Providence Ponds, and Wilsons Promontory. This study aimed to determine indicators of suitable habitat for the species that could assist in identifying potential habitat and sites for planned re-introductions as part of a recovery program. Vegetation and site data (soils, topography, rainfall, fire age-time since fire) were assessed at localities where P. novaehollandiae was recorded. The species occurred in five structural vegetation groups - open-forest, woodland, heathland, shrubland, grassland, with the most common being open-forest and woodland. Grassland and shrubland were restricted to coastal sand-dunes in south Gippsland. Understorey vegetation at most sites was dominated by sclerophyllous shrubs ranging in cover from 10 - 70%. Classification of quadrats produced eight floristic groups in which the trend was for quadrats to cluster according to geographical location. Ordination confirmed the classification pattern and vector-fitting produced significant correlations between vector points and five variables: species richness, latitude, longitude, fire age and annual rainfall. The study identified a range of vegetation communities where P. novaehollandiae occurs and provided evidence that the species is not restricted to floristically rich and diverse heathlands. The findings can be used to determine further localities with suitable habitat. However, factors other than vegetation are also likely to be important in predicting suitable habitat.

Full text

Abstract:

Understanding the habitat requirements of a species is critical for effective conservation-based management. In this study, we investigated the influence of forest structure on the distribution of the yellow-footed antechinus (Antechinus flavipes), a small dasyurid marsupial characteristic of dry forests on the inland side of the Great Dividing Range, Australia. Hair-sampling tubes were used to determine the occurrence of A. flavipes at 60 sites stratified across one of the largest remaining tracts of dry box–ironbark forest in south-eastern Australia. We considered the role of six potential explanatory variables: large trees, hollow-bearing trees, coppice hollows, logs, rock cover and litter. Logistic regression models were examined using an information-theoretic approach to determine the variables that best explained the presence or absence of the species. Hierarchical partitioning was employed to further explore relationships between occurrence of A. flavipes and explanatory variables. Forest structure accounted for a substantial proportion of the variation in occurrence of A. flavipes between sites. The strongest influence on the presence of A. flavipes was the cover of litter at survey sites. The density of hollow-bearing trees and rock cover were also positive influences. The conservation of A. flavipes will be enhanced by retention of habitat components that ensure a structurally complex environment in box–ironbark forests. This will also benefit the conservation of several threatened species in this dry forest ecosystem.

Full text

Abstract:

Abstract. Well-drained, aerated soils are important sinks for atmospheric methane (CH4) via the process of CH4 oxidation by methane-oxidising bacteria (MOB). This terrestrial CH4 sink may contribute towards climate change mitigation, but the impact of changing soil moisture and temperature regimes on CH4 uptake is not well understood in all ecosystems. Soils in temperate forest ecosystems are the greatest terrestrial CH4 sink globally. Under predicted climate change scenarios, temperate eucalypt forests in south-eastern Australia are predicted to experience rapid and extreme changes in rainfall patterns, temperatures and wild fires. To investigate the influence of environmental drivers on seasonal and inter-annual variation of soil–atmosphere CH4 exchange, we measured soil–atmosphere CH4 exchange at high-temporal resolution (< 2 h) in a dry temperate eucalypt forest in Victoria (Wombat State Forest, precipitation 870 mm yr−1) and in a wet temperature eucalypt forest in Tasmania (Warra Long-Term Ecological Research site, 1700 mm yr−1). Both forest soil systems were continuous CH4 sinks of −1.79 kg CH4 ha−1 yr−1 in Victoria and −3.83 kg CH4 ha−1 yr−1 in Tasmania. Soil CH4 uptake showed substantial temporal variation and was strongly controlled by soil moisture at both forest sites. Soil CH4 uptake increased when soil moisture decreased and this relationship explained up to 90 % of the temporal variability. Furthermore, the relationship between soil moisture and soil CH4 flux was near-identical at both forest sites when soil moisture was expressed as soil air-filled porosity (AFP). Soil temperature only had a minor influence on soil CH4 uptake. Soil nitrogen concentrations were generally low and fluctuations in nitrogen availability did not influence soil CH4 uptake at either forest site. Our data suggest that soil MOB activity in the two forests was similar and that differences in soil CH4 exchange between the two forests were related to differences in soil moisture and thereby soil gas diffusivity. The differences between forest sites and the variation in soil CH4 exchange over time could be explained by soil AFP as an indicator of soil moisture status.

Full text

Abstract:

The home ranges and species of trees used by 20 koalas (Phascolarctos cinereus) were determined in a forest in Victoria containing 6 Eucalyptus spp. Eight animals showed a preference for a tree species from those available within their home ranges. Four koalas preferred E. viminalis, 2 E. ovata and 2 E. macrorhyncha. Preference for tree species was detected only where the preferred species was in low abundance within the animal's home range. These observations confirm that koalas may show individual differences in the species of food trees they prefer. E. viminalis, the preferred species of this population, was the predominant tree species within the home range of 15 of the koalas, which may account for the lack of evidence of preference in the majority of animals.

Full text

Abstract:

The day roosting behaviour of the little forest bat (Vespadelus vulturnus), Australia’s smallest bat, was investigated in the context of the planned removal of dead timber within managed woodlands on Phillip Island, Victoria. Between August 1999 and March 2000, 14 female little forest bats were fitted with VHF microtransmitters and tracked to a total of 16 roost trees. All roosts were located in dead timber, 11 in severely decayed remains of eucalypt trees, and five in dead sections of live trees. Roost trees were compared with randomly chosen trees from within the available habitat, for a range of tree characteristics. Female little forest bats selected roosts in trees with dead timber offering many hollows and reduced canopy cover. Furthermore, roost trees were located in areas (0.1-ha plots) with higher densities of these types of trees than in the available habitat. However, there was no difference in the height or diameter of roost trees or roost plots compared with available habitat. Emergence time from roosts was strongly associated with civil twilight (when the centre of the sun is 6° below an ideal horizon), and the number of bats exiting a single roost tree ranged from 1 to 120 (median = 20). Dead trees provide critical roosting habitat and we recommend retention of dead standing trees for conserving little forest bat roosts in managed woodlands.

Full text

Abstract:

The elusive nature of the long-nosed potoroo (Potorous tridactylus) has hindered the collection of long-term data for this threatened species. Between June 2005 and May 2009, data on the ecology of a wild population of long-nosed potoroos located on French Island, Victoria, were collected during a series of research projects. Over this period, 33 individual potoroos were trapped a total of 251 times. Up to nine individuals were known to be alive at once on the 15-ha study site of mature remnant native forest. Adult potoroos showed high site fidelity and significant sexual size dimorphism, with males heavier and having longer head and pes lengths than females. Congruent with other studies, we found no evidence of seasonality in breeding. Births occurred in every month of the year and the testis volume of males did not vary throughout the year. In contrast to previous studies, however, we did not observe peaks in breeding activity. Our research and review of existing literature suggests that the ecology of the long-nosed potoroo is strongly influenced by local environmental conditions and emphasises the need to consider long-term and site-specific data when developing management strategies to conserve this ecologically important species.

Abstract:

The diet of the long-nosed potoroo, Potorous tridactylus, in south-western Victoria, was investigated by the microscopical identification of faecal remains. P. tridactylus is omnivorous: the main component of the diet was fungi, and other important items included hard-bodied arthropods, vascular plant tissues, seeds and fleshy fruits. There was a seasonal switch in the relative proportions of the main dietary components between the autumn-winter and spring-summer periods of the year. During autumn and winter, the main components were fungi and seeds. In spring and summer, fewer fungi were eaten and the proportions of arthropods, plant tissues, fleshy fruit and flowers in the diet increased. Identification of fungal spores revealed the presence of at least 50 species in the diet, most of which have a hypogeal fruiting habit. Hypogeal fungi form ectotrophic mycorrhizal associations with forest trees and are important in the health and productivity of forests. They lack active mechanisms for spore dispersal and are dependent upon mycophagous animals. The role of mycophagous small mammals, such as P. tridactylus, in the health of forest ecosystems may be more important than previously recognised.

Full text

Abstract:

The growth-form composition of grazed and unburnt, grassy forest remnants and ungrazed, frequently burnt, anthropogenic native grasslands in Gippsland, Victoria were compared, using a multivariate, clustering analysis of the growth-form and life-form attributes of 53 forb species. Groups comprising (1) annual forbs, (2) clambering, repent and decumbent perennials, and (3) rosette perennials and rhizomic ground-cover forbs occurred in significantly more forest than grassland quadrats. One group, mostly containing tall erect geophytes with linear basal leaves, occurred in significantly more grassland than forest quadrats. Grassland quadrats contained significantly more tall forbs (> 20 cm) than forest quadrats, whilst forest quadrats contained significantly more forbs of short to medium height (< 20 cm). There was a significant, positive correlation between plant height and frequency of occurrence in grassland quadrats (rs = 0.58, P < 0.001), and a significant, although weak, negative correlation in forest quadrats (rs = -0.29, P < 0.05). Short forbs are likely to have been depleted from grassland sites owing to competition from the dominant tussock grass, Themeda triandra Forsskal. By contrast, ground cover in forest sites is of relatively low stature, biomass and cover, allowing short forbs to persist. The relative paucity of tall forbs from forest remnants is suspected to be at least partly due to intensive stock grazing in the past.

Full text

Abstract:

The diets of Rattus fuscipes and R. lutreolus from a site in central southern Victoria were investigated by faecal analysis. R. lutreolus was predominantly herbivorous; in heath it selected the basal stems of certain cyperaceous herbs, and in forest it ate non-sclerophyllous grasses. Fungi were an important dietary component and seed might be eaten in some quantity for a short time in spring and early summer. R. fuscipes showed little dietary overlap with R. lutreolus; in forest it was reliant on fungi and fibrous plant material from particular grasses; in heath it relied on particular cyperaceous species in winter, and ate primarily fleshy fruit, seed and arthropods in summer. Dietary preferences are compared with the relative abundance of diet items in the habitat. Both species are selective, and this selectivity changes with season. The effects of the availability of preferred diet items on the species' distributions are discussed.

Full text

Abstract:

An outlier of mallee vegetation occurs south of the Great Dividing Range in Victoria in a rain shadow region (annual rainfall approx. 500 mm) about 50 km west of Melbourne. A Eucalyptus behriana open-scrub with a sparse understorey of chenopods, mosses, lichens and some grasses occurs on solonetz soil on lateritized Tertiary sandy clays and on skeletal soils on Ordovician slates and sandstones. The dryness of the mallee site is probably exacerbated by the smaller rate of water infiltration and greater salinity of the solonetz soil under E. behriana compared with the solodic soil, in the moister area further north, under an open-forest of E. microcarpa. The multistemmed habit of E. behriana appears to be partly genetically fixed. Hollow lignotuberous rings, filled to a depth of about 15-25 cm with brown, nutrient-rich humus, are common. Pattern analysis of the distribution of stems of E. behriana indicated strong clumping at about 9 m², due to the multistemmed habit, and weaker clumping at about 600 m², which correlated with the size of groups of dense, spindly individuals of E. behriana, resulting from a past phase of gap regeneration.

Full text

Abstract:

Predation rates of nests at human-induced habitat edges may be greater than in forest interior due to differences in predator assemblages and predator activity. I compared the predation rates on 192 artificial nests containing plasticine eggs placed in forest edge and interior sites at Bunyip State Park, Victoria. The nest-predation rates at the forest edge sites were significantly greater (mean = 52–58%) than that at the forest interior sites (mean = 30–39%). The relative rates of predation by birds compared with mammals were significantly greater at forest edge sites (mean = 78–94%) than at forest interior sites (mean = 36–67%). Higher rates of nest predation at forest edges appeared to be due to greater densities of avian predators such as the grey shrike-thrush (Colluricincla harmonica), and/or lower abundances of small mammals. However, biases towards certain predator types may mask real, or create false, patterns in predation rates of artificial nests. A better understanding of how predators respond to artificial nests compared with natural nests is required. Until then, results of predation studies that use artificial nests should be interpreted with caution.

Full text

Abstract:

Old growth forests have many key values, but temporal changes across their spatial extent are poorly understood. This includes large parts of Australia and is a major knowledge gap given the extent of human and natural disturbances in the Australian forest estate over past decades. We integrated spatial data on the timing and extent of fire and logging across mapped forest and woodland cover in different Ecological Vegetation Class (EVC) groups to quantify disturbance of the old growth forest and woodland estate in Victoria since 1995, including after the 2019–20 wildfires. We found ~77% of old growth forest and woodlands have been disturbed by fire and logging over the past 25 years. Disturbance was particularly marked in some EVCs, such as the Wet and Damp Forest and the Subalpine Woodlands. In contrast, relatively little of the Modelled Old Growth Forest and Woodland has been disturbed between 1995 and 2020 in other EVCs such as in Plains Woodlands and Heathy Woodlands. Wildfire was the primary driver of disturbance in Modelled Old Growth Forest and Woodland. We argue that a range of strategies is critical to increase protection of undisturbed old growth forest. These include re-assessing disturbance data layers to ensure that areas of old growth that have been burned at low severity are protected, and reducing the size of old growth patches to be conserved. There is also a need to increase levels of protection of young forests to enable them to grow through to an old growth state.

Full text

Abstract:

The nesting requirements of the yellow-tailed black-cockatoo (Calyptorhynchus funereus) were studied at 68 sites in Eucalyptus regnans forest in the Strzelecki Ranges, South Gippsland, Victoria. Nest trees were located and their characteristics related to forest stand variables. Eighteen nest hollows were found. Nest trees had a mean diameter at breast height of 2.5 m, a mean estimated age of 221 years, a mean height of 58 m and for live nest trees a mean crown diameter of 22 m. The currently proposed rotation time for silvicultural systems of 80-150 years will reduce the number of hollow-bearing trees suitable for nesting yellow-tailed black-cockatoos. Adequate numbers of trees must be retained in logged areas and wildlife corridors and reserves, and protected to ensure a continual supply for yellow-tailed black-cockatoos and other hollow-dependent species. If agonistic behaviour is operating between female yellow-tailed black-cockatoos, nesting potential may be enhanced if trees retained on coupes are evenly distributed rather than clumped. Silvicultural systems that facilitate the protection of trees retained on coupes would benefit the conservation of the yellow-tailed black-cockatoo.

Full text

Abstract:

The responses of seedlings of Tristaniopsis laurina and Acmena smithii, two important tree species in riparian warm temperate rainforest communities in Victoria, are investigated in relation to flood disturbances. Freshly germinated A. smithii seedlings had died within 5 weeks of complete waterlogging in the greenhouse, and although the young T. laurina seedlings survived waterlogging for 14 weeks, their growth rate was curtailed. Nine-month-old seedlings of both species were found to be relatively tolerant to waterlogging, forming aerenchymatous surface roots after 40 days of flooding. Neither species suffered leaf abscission or demonstrated any other signs of water stress commonly associated with flood intolerant species. In experiments to determine the resilience of these species to physical flood damage, both species also demonstrated a capacity to regenerate vegetatively following the removal of above ground parts in young seedlings. The heartwood of T. laurina was found to be more decay resistant than that of other species in the field including that of A. smithii. The significance of these results are discussed in relation to other factors examined in earlier papers adding to the understanding of the ecological status of these species within the riparian rainforest communities.

Abstract:

DAVID Lindenmayer and Jerry Franklin are the two most influential forest conservation biologists of the past decade and will probably remain so for the coming decade. Each has contributed significantly to forest research, management, biodiversity conservation and policy. Lindenmayer is an Australian based at the Australian National University in Canberra who has worked mainly in the temperate eucalypt forests of Victoria and southeastern New South Wales. Most of his research is wildlife oriented, with an emphasis on arboreal marsupials and the impacts of forest management on forest vertebrates. Franklin is an American at the University of Washington, Seattle in the Pacific Northwest. His research is more botanically oriented, with an emphasis on the impacts of forest management on forest structures (e.g., large trees and logs) and processes. Of the two, Franklin has had the greatest involvement in the political, economic and social processes driving the modern change in forestry practices and attitudes. Together they form a formidable team to present a summary and an analysis of how temperate forests globally can and should be managed. Their goal is not just to enhance biodiversity and other ecological values, but to ensure the long-term sustainability of forest ecosystems. Only when forests are managed sustainably to protect biodiversity can forest managers guarantee the many social and economic benefits derived from the world’s forests, including wood production.

Full text

Abstract:

Aquatic ecosystems around the world have been massively altered through vegetation clearance and changed flow regimes accompanying agricultural development. Impacts may include disrupted dispersal for aquatic species. We investigated this in lentic (standing) waterbodies in agricultural and predominantly forested landscapes of the box-ironbark region of central Victoria, Australia. We hypothesised that higher representation in forested than agricultural landscapes (i.e. ‘forest-bias’) for a species may reflect an ability to disperse more easily through the former, resulting in lower genetic structure in forested than in agricultural landscapes. Conversely, ‘cosmopolitan’ species would show no difference in genetic structure between landscape types. Molecular genetic analyses of a forest-biased diving beetle, Necterosoma wollastoni, and a cosmopolitan waterboatman, Micronecta gracilis, revealed the following, for both species: (1) no evidence for long-term barriers to gene flow in the region, (2) lack of contemporary genetic differentiation over 30 000 km2 and (3) random distribution of related genotypes in space, implying that neither forest nor farmland inhibits their dispersal in a concerted fashion. Taken together, these results indicate very high gene flow and dispersal in the past and present for both these species. Massive landscape change may have little impact on movement patterns of lentic invertebrates that have evolved high dispersal capabilities.

Full text

Abstract:

Knowledge of the gliding performance of gliding mammals is fundamental to understanding how these species have adapted to their environment and is of increasing relevance to their conservation. I describe aspects of the glide performance of the yellow-bellied glider (Petaurus australis) based on 22 glides of 17 individuals within 20–30-m-high open forest in western Victoria. Gliders launched into a glide from a horizontal branch that was, on average, 2.8 m below the top of a tree, 5.2 m out from the main trunk and 18.5 m above the ground. Gliders landed on the trunks of trees 5.8 m above the ground. The mean horizontal glide distance was 25.2 ± 1.5 m (s.e.) (range = 19–45 m), producing a glide ratio (horizontal distance/height dropped) of 2.0 and a glide angle of 27.3°. These values are similar to those reported for other gliding petaurids in low-canopy forest. This knowledge should be used to guide the management of habitat connectivity for yellow-bellied gliders.

Full text

Abstract:

A trapping study of small mammals within heath communities near Cape Otway was conducted during April-August 1989. The purpose was to describe the distribution patterns of several small mammals in relation to a floristic and structural description of the vegetation. Two species of rodent (Rattus lutreolus, R. fuscipes), two species of dasyurid (Antechinus stuartii, A. minimus) and one species of bandicoot (Isoodon obesulus) were trapped frequently enough for statistical analysis. A. stuartii was trapped significantly more often in the Heathy Open-forest than in the Closed Heath community, in contrast to A. minimus and R. lutreolus, which were captured significantly more often in Closed Heath. There was no significant difference in the distributions of R. fuscipes and I. obesulus between communities. Within the Closed Heath community only R. fuscipes displayed significant distribution patterns between sub-communities. In the Heathy Open-forest the distribution of captures among sub-communities varied significantly for both species of Antechinus and for R. lutreolus. Floristic and structural cues, as well as ground cover, were associated with the spatial distribution of dasyurid and rodent species. Bandicoot dispersion was associated only with vertical vegetation diversity. The importance of interspecific avoidance in contributing to the observed distribution patterns of both dasyurid and rat species cannot be dismissed.

Full text

Abstract:

Predation by European red foxes is believed to be the major cause of the extinction and decline of a large number of native medium-sized terrestrial mammals in Australia. We examined the impact of poisoning of foxes on the relative abundance of a group of medium-sized mammals in an experiment conducted in three large forest blocks in south-eastern Australia. The blocks consisted of paired sites, as follows: one site where poison baiting was used to control foxes (treatment site) and one where foxes were not controlled (non-treatment site). At all six sites, the population responses of a range of mammals were measured, and compared between treatment and non-treatment sites. The relative fox abundance, as indexed by bait-take, declined during the course of the study at treatment sites and to a lesser extent at non-treatment sites. The decline in bait-take at non-treatment sites was most likely due to treatment sites acting as ecological traps, so that reduced intra-specific competition attracted foxes from non-treatment to treatment sites, where they were subsequently poisoned. There was a significant treatment effect for the abundances of total mammals, long-nosed potoroos, southern brown bandicoots and common brushtail possums, with higher abundances at treatment sites than at non-treatment sites. Common ringtail possums increased in abundance during the course of the study, with no significant difference between treatment and non-treatment sites. There was no significant effect of time or treatment on the abundance of long-nosed bandicoots. The increase in the abundance of native mammals at treatment sites was most likely due to a lower predation pressure by foxes brought about by fox control, and the smaller increase in abundance in non-treatment blocks was likely due to the ecological-trap effect because of fox baiting at treatment sites. The present study demonstrated that broad-scale fox control can lead to increases in the abundance of native mammals in forested habitats, without recourse to aerial baiting or fences. The study also demonstrated that the influence of fox control on the fox abundance can extend well beyond the perimeter of the area baited.

Full text

Abstract:

A well-dated pollen record from Chapple Vale in the north of the Otway region provides a detailed history of vegetation and environments through the last c. 7000 years. From the commencement of the record, a stand of cool temperate rainforest, dominated by Nothofagus cunninghamii (Hook.) Oerst., grew on or around the site and was surrounded by eucalypt-dominated tall open forest. Between c. 5200 and 4600 years BP (before present), the rainforest declined and tall open forest predominated. Some time after 4400 years BP there was a major and consistent increase in charcoal values, suggesting an increase in burning, the progressive development of scrub–heath vegetation on site and the replacement of tall open forest vegetation by eucalypt woodland surrounding the site. The fossil evidence for N. cunninghamii on the site and its present restriction to wetter areas and gullies of the Otway Ranges indicate, from the application of the present bioclimatic range of the species, a mean annual temperature and winter temperatures that were c. 1˚C cooler than present, and summer temperatures that were possibly slightly cooler than present, together with a much higher effective precipitation from the commencement of the record until c. 4600 years BP. These climatic estimates are in accord with those derived from a similar study of changing distributions of N. cunninghamii in the Central Highlands of lower mean annual and cooler summer temperatures and higher effective precipitation over this time span. However, for winter, the evidence is equivocal. While the Otway estimates suggest lower temperatures, the Central Highlands findings show slightly higher temperatures. Taking into account additional present-day records for N. cunninghamii, it is likely that the Otway estimates are the most reliable.

The dominant species of large macropods in Victoria are the Eastern Grey Kangaroo (Macropus giganteus) and the Southern (= Western) Grey Kangaroo (M. fuliginosus). On the limited historic data available there is no indication that their ranges have changed since European settlement. The Red Kangaroo (M. rufus) was restricted to the northwest corner of the state, then as now. Moderate densities of Grey Kangaroos at settlement increased under forest clearing, probably peaking about the mid-nineteenth century. With intensification of farming and associated heavy hunting they declined again to establish by about the turn of the century the distribution of modera te density that we see today.

Abstract:

The distribution of Phytophthora cinnamomi in the Brisbane Ranges National Park of Victoria was mapped and related to vegetation susceptibility, disease severity and past distribution. P. cinnamomi extended its distribution from 1% of the park in 1970 to 31% in 1980-81. The dispersal of the pathogen has occurred through roadworks and subsequent drainage of water-borne zoospores. In 1980-81, 50% of 1191 grids (250 x 250 m) occurred in susceptible vegetation (sclerophyllous forest/woodland). Of these, 45% (266 grids) were moderately diseased and 16% (95) severely diseased. Stands of dead trees occurred in 29 severely diseased grids which were in shallow gullies with impeded drainage. The 39% (231) of susceptible vegetation which remained unaffected occurred mainly on ridges and hilltops. P. cinnamomi was isolated from 3% of apparently resistant vegetation (graminoid forest/woodland). Restriction of access is recommended to the remaining areas of susceptible unaffected vegetation.

Full text

Abstract:

A series of spotlight transects were carried out over a two-year period within a 7-ha area of the Wombat State Forest, Victoria, which contained nestboxes used by feathertail gliders, Acrobates pygmaeus. Spotlighting was carried out on foot through open forest, not along tracks, and only one feathertail glider was detected in 13.8 h of spotlighting. The nestboxes were checked on days following spotlighting surveys and 72 captures of feathertail gliders were made over the same two- year period. Spotlighting can provide important information on the biology of feathertail gliders when used in long-term scientific studies by experienced spotlighters. However, it is an unsatisfactory technique for broad surveys of feathertail gliders, and nestboxes provide a better technique but require a longer time-frame and additional cost.

Abstract:

The orb-weaving spider genus Novaranea Court & Forster, 1988, previously known only from New Zealand, is here reported from Australia for the first time with the description of a new species. Generic affinities, here based on characteristic shapes of the median and terminal apophyses of the male pedipalp, remain somewhat ambiguous as some of the endemic New Zealand araneine genera remain to be tested within a rigorous phylogenetic analysis. Novaranea courti n. sp. is found in the southeastern parts of Australia, including New South Wales, Victoria and Tasmania. Mature spiders are generally found between January and March, although some specimens were collected in April, June and November. Novaranea courti n. sp. appears to prefer forest habitats (e.g. Southern Beech (Nothofagus) forest and Eucalyptus/Casuarina woodland), but was also found in more open areas such as grassand heathland.
