We review the distribution, habitat and conservation status of the eastern pygmy-possum (Cercartetus nanus) in Victoria. Data on the habitat occurrences and rates of detection were gleaned from 133 published and unpublished fauna surveys conducted from 1968 to 2003 in Gippsland; northern Victoria; the Melbourne area and south-western region. C. nanus was reported from a broad range of vegetation communities, which predominantly included a dense mid-storey of shrubs rich in nectar-producing species such as those from the families Proteaceae and Myrtaceae. Survey effort using a range of methods was immense across surveys: 305,676 Elliott/cage trap-nights, 49,582 pitfall trap-nights, 18,331 predator remains analysed, 4424 spotlight hours, and 7346 hair-sampling devices deployed, 1005 trees stagwatched, and 5878 checks of installed nest-boxes. The surveys produced 434 records of C. nanus, with Elliott/cage trapping, pitfall trapping and analysis of predator remains responsible for the vast majority of records (93%). These data and those from the Atlas of Victorian Wildlife indicate that although C. nanus has a widespread distribution in Victoria, it is rarely observed or trapped in fauna surveys. Only 11 (8%) of the surveys we reviewed detected >10 individuals. C. nanus is likely to be sensitive to several recognised threatening processes in Victoria (e.g., feral predators, high frequency fire, feral honeybees). There is also evidence of range declines in several regions, which suggests that the species is vulnerable to extinction. Therefore, we recommend that it be nominated as a threatened species in Victoria.

AbstractWe examined mitochondrial DNA (COI) variability and distribution of Stereotydeus spp. in Victoria Land and the Transantarctic Mountains, and constructed Neighbour Joining (NJ) and Maximum Likelihood (ML) phylogenetic trees using all publicly available COI sequences for the three Stereotydeus species present (S. belli, S. mollis and S. shoupi). We also included new COI sequences from Miers, Marshall and Garwood valleys in southern Victoria Land (78°S), as well as from the Darwin (79°S) and Beardmore Glacier (83°S) regions. Both NJ and ML methods produced trees which were similar in topology differing only in the placement of the single available S. belli sequence from Cape Hallett (72°S) and a S. mollis haplotype from Miers Valley. Pairwise sequence divergences among species ranged from 9.5–18.1%. NJ and ML grouped S. shoupi from the Beardmore Glacier region as sister to those from the Darwin with pairwise divergences of 8%. These individuals formed a monophyletic clade with high bootstrap support basal to S. mollis and S. belli. Based on these new data, we suggest that the distributional range of S. shoupi extends northward to Darwin Glacier and that a barrier to dispersal for Stereotydeus, and possibly other arthropods, exists immediately to the north of this area.

The impact of time since fire after two consecutive wildfires 44 years apart (1939 and 1983) within the same area, and the distance from the fire boundary (<100 m or 500-2000 m), were investigated in relation to the distribution and abundance of arboreal marsupials in 1994. Arboreal marsupials were censused by stagwatching and spotlighting in two relatively young age classes of mountain ash (Eucalyptus regnans) dominated forest in the Central Highlands of Victoria. Five species of arboreal marsupial were detected, but only three were detected in sufficient numbers to determine habitat preferences. Petauroides volans (greater glider) was statistically more abundant in 1939 regrowth forests, while Trichosurus caninus (mountain brushtail possum) showed no significant preference for either age class of forest. All but one record of Gymnobelideus leadbeateri (Leadbeater's possum) came from young forest, though the effect of age-class was not statistically significant. Distance from fire boundary explained little or no variation in mammal distribution or abundance. While the actual number of hollow-bearing trees was similar in both age classes of forest, the long-term lifespan of hollow-bearing trees in more recently burnt forest is predicted to be lower than in unburnt or not recently burnt forest. Post-fire salvage logging following the 1983 wildfires appears to have reduced the number of hollow-bearing trees at sites burnt in 1983.

ABSTRACT Sediments ranging in age from Tertiary to Late Quaternary are exposed at Duck Hawk Bluffs near Sachs Harbour on Banks Island (NWT). Fossil pollen and macrofossils of plants and arthropods from various nonglacial sediments at Duck Hawk Bluffs and related sites on Banks and Victoria islands make it possible to infer some of the climatic/biotic changes during that time span. At the time of deposition of the Miocene-Pliocene Beaufort Formation, southern Banks Island supported a rich coniferous forest, containing several species of conifers and various hardwoods. An upper member of the Beaufort Fm. is characterized by a more depauperate coniferous forest assemblage, yet still contains plants now foreign to the entire NWT. The late Tertiary/early Quaternary Worth Point Formation was deposited when larch-dominated forest-tundra characterized southern Banks Island. Larch may have grown on the island during the following Morgan Bluffs Interglaciation (>730 ka), but in other respects the flora and fauna of that time seem to have been low Arctic in character. Similar conditions existed during the Cape Collinson Interglaciation ( = Sangamon), though by that time, coniferous trees had definitely disappeared from the island.

The southern eucalypt leaf beetle, Chrysophtharta agricola (Chapuis), is an outbreak insect pest of commercial Eucalyptus globulus Labill. plantations in south-eastern Australia. We surveyed a young E. globulus family trial in southern Tasmania to determine whether genetic variation existed in the susceptibility of trees to C. agricola field oviposition. The family trial consisted of 225 families, derived from open-pollinated seed collected from native stands at 24 different localities, representing nine geographic subraces. The survey showed that E. globulus subraces from Victoria were significantly more susceptible to C. agricola oviposition than Tasmanian subraces. Significant additive genetic variation within subraces was evident for the number of egg batches, larval clutches and their combination (infestation level), although these heritability scores were all low (egg batches h2op = 0.09; larval clutches h2op = 0.14 and infestation level h2op = 0.11). Subsequent tree defoliation was significantly positively correlated with infestation at a phenotypic, genetic and environmental level. No significant differences in C. agricola oviposition on foliage sprigs was detected among subraces in an ex situ caged oviposition experiment. However, the cage experiment proved to be a good predictor of field oviposition, accounting for 70 and 88% of variation in field oviposition among localities and subraces, respectively.

Patterns of geographic variation in morphological and chemical characters are documented in Eucalyptus diversifolia Bonpl. (soap mallee, white coastal mallee). This species is found in coastal and subcoastal Australia from southern Western Australia to Cape Nelson (western Victoria), with a number of disjunctions in the intervening region. Morphological data from adult plants collected at field localities and seedlings grown under uniform conditions were analysed using univariate and multivariate methods, including oneway ANOVA, multiple comparison tests, non-metric multidimensional scaling (NMDS), nearest neighbour networks, and minimum spanning trees. Seedling material was tested for isozyme polymorphism, and adult leaf flavonoids were analysed using liquid chromatography. Morphological and chemical characters are also documented in E. aff. diversifolia, a closely related but unnamed taxon restricted to ironstone outcrops near Norseman (WA), and putative E. diversifolia- E. baxteri hybrids from Cape Nelson. Congruent patterns in data sets distinguish three groups of E. diversifolia adults and progeny: (1) those to the west of the Nullarbor disjunction; (2) South Australian populations to the east of this disjunction; and (3) those from Cape Nelson. Formal taxonomic recognition of the three forms at subspecific level is established, namely E. diversifolia subsp. diversifolia, E. diversifolia subsp. hesperia, and E. diversifolia subsp. megacarpa. Patterns of geographic affinity between populations are consistent with a hypothesis of genetic exchange between normally disjunct regional populations of E. diversifolia via coastal land-bridges exposed during periodic times of low sea level since the mid Tertiary.

Повний текст джерелаАнотація:
The brown falcon, Falco berigora, is one of Australia's most common and widespread raptors, inhabiting a broad array of habitats and most climatic zones across Australia. We monitored a large, marked population (44–49 pairs) over three annual breeding seasons in southern Victoria. Reproductive parameters such as clutch size and the duration of parental care were constant across years. However, there were marked differences in brood size and the proportion of pairs breeding. Both sexes of falcons were found to have high territory and mate fidelity, with only 10% of members of each sex changing territories during the study. Falcons were flexible in their choice of nest sites, using a variety of tree species and even isolated nest trees. Nest sites and territories were regularly distributed throughout the study area, with the density of the population the highest on record for this species. The diet of the population as a whole was very broad, but each pair predominantly specialised on either lagomorphs, small ground prey, small birds, large birds or reptiles. Individuals that changed territory within the study area also switched their diet according to the predominant land-use within the new territory and thus prey availability. We argue that, at the population level, broad dietary breadth, flexibility in choice of nest site, and a conservative, static breeding strategy allows the species to persist in a broad range of environments, possibly through 'bet-hedging'. At the individual level, changeable dietary specialisation, high territory fidelity, strong year-round territorial defence, confining breeding to years when individual conditions were favourable and adjusting brood sizes when required appear to be the main strategies enabling brown falcons to thrive under a variety of conditions.

"The Effect of Antecedent Fire Severity on Reburn Severity and Fuel Structure in a Resprouting Eucalypt Forest in Victoria, Australia."

Research highlights—Feedbacks between fire severity, vegetation structure and ecosystem flammability are understudied in highly fire-tolerant forests that are dominated by epicormic resprouters. We examined the relationships between the severity of two overlapping fires in a resprouting eucalypt forest and the subsequent effect of fire severity on fuel structure. We found that the likelihood of a canopy fire was the highest in areas that had previously been exposed to a high level of canopy scorch or consumption. Fuel structure was sensitive to the time since the previous canopy fire, but not the number of canopy fires. Background and Objectives—Feedbacks between fire and vegetation may constrain or amplify the effect of climate change on future wildfire behaviour. Such feedbacks have been poorly studied in forests dominated by highly fire-tolerant epicormic resprouters. Here, we conducted a case study based on two overlapping fires within a eucalypt forest that was dominated by epicormic resprouters to examine (1) whether past wildfire severity affects future wildfire severity, and (2) how combinations of understorey fire and canopy fire within reburnt areas affect fuel properties. Materials and Methods—The study focused on ≈77,000 ha of forest in south-eastern Australia that was burnt by a wildfire in 2007 and reburnt in 2013. The study system was dominated by eucalyptus trees that can resprout epicormically following fires that substantially scorch or consume foliage in the canopy layer. We used satellite-derived mapping to assess whether the severity of the 2013 fire was affected by the severity of the 2007 fire. Five levels of fire severity were considered (lowest to highest): unburnt, low canopy scorch, moderate canopy scorch, high canopy scorch and canopy consumption. Field surveys were then used to assess whether combinations of understorey fire (<80% canopy scorch) and canopy fire (>90% canopy consumption) recorded over the 2007 and 2013 fires caused differences in fuel structure. Results—Reburn severity was influenced by antecedent fire severity under severe fire weather, with the likelihood of canopy-consuming fire increasing with increasing antecedent fire severity up to those classes causing a high degree of canopy disturbance (i.e., high canopy scorch or canopy consumption). The increased occurrence of canopy-consuming fire largely came at the expense of the moderate and high canopy scorch classes, suggesting that there was a shift from crown scorch to crown consumption. Antecedent fire severity had little effect on the severity patterns of the 2013 fire under nonsevere fire weather. Areas affected by canopy fire in 2007 and/or 2013 had greater vertical connectivity of fuels than sites that were reburnt by understorey fires, though we found no evidence that repeated canopy fires were having compounding effects on fuel structure. Conclusions—Our case study suggests that exposure to canopy-defoliating fires has the potential to increase the severity of subsequent fires in resprouting eucalypt forests in the short term. We propose that the increased vertical connectivity of fuels caused by resprouting and seedling recruitment were responsible for the elevated fire severity. The effect of antecedent fire severity on reburn severity will likely be constrained by a range of factors, such as fire weather.

What is that queer plant that drapes itself chaotically over the top of trees and bushes? You know the one along the road on the way into town?
Ah yes! You mean the one with no leaves, that looks like tangled yarn caught up in the branches?
Yes, it looks like its floating airborne on top of the canopy, smothering and embracing at the same time.
Well, that's the one with the common name of snotty gobble or Dodder-Laurel!!! Dodder may look chaotic but that only demands on how you view it.
I can’t stop thinking about it, Let’s find out what it’s doing.
‘Learning to be affected’ says Bruno Latour is to be 'moved, put into motion by other entities, humans or non-humans’(2004). And this is what happened to Down the Road Projects when we became intrigued with local plant parasites where we live in central Victoria, Australia.
This paper explores how we became ensnared by planty agencies. By charting our multispecies and human interactions in the course of developing the art project, Becoming Differently (2018), we trace how parasites came to be an important theme of the art, how they infiltrated the art works, how they changed our understanding of parasites, how they enticed us into the bush and developed our style of collaboration.
We ‘queery’ what it means to be ‘drawn towards’ particular plants, we wonder who or what is ‘drawing’, and how these particular plants inflected our art and writing. We consider how we were moved towards different ways of figuring identity and belonging, and how we grappled with practices and modes of engagement with complex issues of identity, belonging and nature in a settler-colonial situation, and how this led to us to become differently entangled in the place where we live.

In the fall of 2016, an unusual phenological event occurred in Quercus garryana Douglas ex Hook. in Victoria, British Columbia. After normal autumn leaf drop, some trees burst bud and leafed out prematurely in late October. This allowed a comparison of the cold hardiness of the prematurely flushed and non-flushed trees over the following year. Cold hardiness of five tree pairs (premature fall flush and non-flush) in three locations in Victoria was assessed bi-weekly over the dehardening period in January–March 2017 and again over the hardening period in September–December 2017. Cold hardiness of 10 non-flushed trees from the most northerly population of Q. garryana was also assessed twice in spring 2017. Between January and March, all trees dehardened, but cold hardiness was greatest in non-flushed trees on the first sampling date, and thereafter, the non-flushed trees dehardened more rapidly than the prematurely flushed trees. Index of injury was consistently 10% greater in Victoria than in northern trees. In fall 2017, trees that had flushed prematurely in fall 2016 had the same cold hardiness as non-flushed trees. Hardiness of all trees decreased from mid-September to the end of October, followed by rapid hardening in November and December of 2017.

Effective management of tree-hollow-dependent wildlife is enhanced by detailed knowledge of the trees used for shelter and breeding. We describe the characteristics of 52 den trees and hollows (cavities) used by the yellow-bellied glider (Petaurus australis) in the south-west of its geographic range. We compared the following attributes of den trees to reference trees: tree height, diameter at breast height, hollow entrance height, hollow entrance diameter, cavity diameter, cavity depth, cavity roof height and cavity wall thickness. Dens and reference trees showed a highly significant multivariate difference (P<0.001), with these variables explaining 64% of the variance. Univariate analyses revealed that hollow entrance height was significantly different between den trees (9.0±0.5m) and reference trees (5.5±0.3m). While not significant, den trees tended to have narrower hollow entrances, deeper cavities and thinner walls than reference trees; cavities used by yellow-bellied gliders, on average, measured 36.8cm deep and 18.0cm in diameter, and had entrances 10.6cm in diameter. These observations should assist forest management for this species.

Nine phascogales (7 females, 2 males) were radio-tracked between March and July 1999 to investigate the spatial organisation of this species in spatially limited habitat near Euroa, Victoria. In this area, approximately 3.6% of the original woodland vegetation remains after 150 years of agricultural clearing. Most wooded habitat is confined to narrow linear strips along roads and streams. However, these remnants are on fertile soils and, because they have not experienced intensive harvesting, the density of large old trees is over 10 times that found in nearby State Forests and Parks. Female phascogales were monitored for 13–38 days over periods of 5–15 weeks. The size of home ranges of females was 2.3–8.0 ha, and averaged 5.0 ha. This value is one-eighth the mean home-range size previously recorded for the species in contiguous forest in Victoria. All individuals used multiple nest trees, with nests generally located in trees >80 cm diameter at breast height. Although fragmented and spatially limited, the stands of large old trees on productive soils near Euroa provide a network of well connected, high-quality habitat for phascogales. The relatively dense population of phascogales in these remnants suggests that prior to agricultural clearing and timber harvesting, phascogales may have been much more common in Victoria than at present.

Net pasture production has been monitored over time on an on-going Pinus radiata-pasture agroforestry experiment located at Carngham, Victoria. Established in 1983 by thinning a 2-year-old plantation, the study contains five treatments (systems): open pasture (no trees), 60 trees/ha, 200 trees/ha wide-spaced, 200 trees/ha 5-row belt and 1360 trees/ha. Net pasture production was only weakly affected by the proximity of trees in the 60 trees/ha and 200 trees/ha wide-spaced systems. However, in the 200 trees/ha 5-row belt system, pasture production was often significantly less within the tree zone and at 1.5 m from the tree edge compared with production at 10.5 m from the tree edge. While there was a trend for greater pasture production at 10.5 m and 18 m from the tree line than occurred in the open pasture system, the width of pasture adjacent to the 5-row belts was too narrow (36 m) to demonstrate any shelter benefit on pasture production. From 1990 to 1992, pasture production (kg ha-1) for each system was similar, although production tended to decrease with increasing tree stocking. Following the cessation of pruning (1992), pasture production was significantly reduced by increased tree stocking, such that pasture production in the 200 trees/ha wide-spaced and 200 trees/ha 5-row belt systems was 60% and 69% and 23% and 67% of open pasture in 1993 and 1994 respectively.

An ecological thinning trial was established in 2003 in north-central Victoria as part of the development of an ecological management strategy to support the newly created Box-Ironbark Parks and Reserves System. The objective of the trial was to restore diversity of habitat structure to declining Box-Ironbark forests and woodlands. Three ecological thinning techniques were designed around several principles: reducing total basal-area of trees and retaining levels of patchiness whilst retaining large trees. Thinning treatments were implemented in 30 ha plots at four conservation reserves south of Bendigo, Victoria. A range of ecosystem components were monitored before and after thinning. A woody-debris removal treatment was also set-up at a 1 ha scale within thinning treatments. Prior to thinning, plots were dominated by high numbers of coppice regenerated trees with few of the trees sampled considered large, resulting in low numbers of tree hollows and low loadings of coarse woody debris. It is anticipated that the establishment of the ecological thinning trial (Phase I), is the beginning of long-term monitoring, as effects of thinning on key habitat values may not be apparent for up to 50 years or more. The vision for restoration of Box-Ironbark forests and woodlands is one of a mosaic landscape with a greater diversity of habitat types including open areas and greater numbers of larger, hollow-bearing trees. This paper summarises the experimental design and the techniques adopted in Phase I of this project during 2003-2008.

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.

A plantation established in 1981 on a grazing property was thinned in 1983 to give trees spaced at: (i) no trees (a grazing control), (ii) 8 mx 12 m, (iii) 4 mx9 m, (iv) 4 mx3 m in a 5-row belt then a 10-row pasture gap, and (v) 2 mx3 m (original spacing). By 1989 the density of trees in these systems was slightly reduced by windthrow, animal damage and thinning to (ii) 60 trees/ha, (iii) 200 trees/ha wide-spaced, (iv) 200 trees/ha 5-row belt and (v) 1360 trees/ha. All trees in systems (ii), (iii) and (iv) had been pruned to 6 m by late 1992. The sheep stocking policy was initially based on a set 10 sheep ha-1. Since 1991 the stocking rate has been varied yearly in an attempt to maintain similar production per sheep. The pastures were re-sown in 1989 with perennial rye-grass and subterranean clover cultivars. Since 1991, wool production per ha from the 200 trees/ha wide-spaced system has been consistently less than in systems (i), (ii) and (iv). Wool production among systems differed significantly since 1992. Expressed as a percentage of wool production achieved on open pasture, the relative values for the agroforestry systems from 1990 to 1994 as follows.

The effect of caging trees to exclude insect visitors on the fruit density, seediness, and quality of Imperial mandarin in north-western Victoria was investigated during 1990-91.The major effect of caging was a reduction in fruit seediness, with open trees having 5-16% of fruit seedless and caged trees 80-95%. The number of seeds per fruit ranged from 0-18 and 0-5 for open and caged trees, respectively. Caging trees had no effect on mean fruit density, mean fruit weight, fruit juiciness, soluble solids and percentage citric acid. These results provided further evidence for parthenocarpic fruit development by Imperial mandarin.

Since 1950, 199 nesting sites of peregrine falcons (Falco peregrinus) have been found in Victoria. Over half (51%) are on natural cliffs, 37% in trees and 12% on human-made structures and stone quarry faces. Most eyries on natural cliffs occur in the uplands (>200 m elevation) or along the coast. Tree eyries are located in hollows and in stick nests of other birds; most of these are within the distributions of red gums and belahs. Human-made structures (other than quarries) supporting nests include dam walls, silos, electricity pylons and buildings. Factors believed to influence the breeding distribution of peregrine falcons in Victoria are discussed; these include volcanic activity, landform and elevation, water, vegetation, climate, other birds and humans. The influence of human activities on the distribution of nesting peregrine falcons appears to have been positive. However, the future of the population of peregrine falcons nesting in tree hollows is of concern: it is likely that large trees with nest hollows will be destroyed or will fall from decay long before sufficient numbers of replacement trees are available.

Banksia integrifolia L.f. has been in decline on calcareous sands of the Yanakie Isthmus, southern Victoria, since early 1980. Early studies indicated that the decline is associated with a particular soil condition possibly a nutritional imbalance involving Fe. However, in foliage samples collected from the three main soil types of the Isthmus, declining trees had similar concentrations of Fe but lower concentrations of Ca than healthy trees. Comparisons were made of seasonal variation in concentrations of macro- and micro-nutrients in foliage and litterfall from healthy trees (to minimise secondary changes associated with decline) within healthy and declining sites on the same soil type. On average, litterfall and the nutrient content of litterfall was greatest within the canopy area of B. integrifolia of the healthy stand. Banksias of the healthy stand also had greater concentrations of N, P, K and Na in fully-expanded leaves, resorbed greater proportions of phloem-mobile nutrients from senescent leaves and accumulated more Ca in senescent leaves. However, there was no evidence of nutritional imbalance in healthy trees within declining stands. It is argued that the lower foliar Ca in declining trees on three soil types and lower nutritional status of healthy trees within declining stands were due to lower productivity and lower water use and were therefore a result or an indication of decline rather than a cause.

Statistical models of the patterns of den-tree choice by the mountain brushtail possum (Trichosurus caninus) at Cambarville in the mountain ash (Eucalyptus regnans) forests of the central highlands of Victoria, south-eastern Australia are presented. These models enable us to predict, for a particular possum, the choice of den tree on the basis of patterns of recent den-tree usage and are required for individual-based simulation studies. The models show that the pattern of den-tree use is more complicated than might have been expected, in the sense that it is animal-specific, and that old animals exhibit more complicated patterns of den-tree choice than young ones.

The use of den trees by a population of the mountain brushtail possum (Trichosorus caninus) in forests of mountain ash (Eucalyptus regnans) at Cambarville, in the central Highlands of Victoria, is described. Relationships are explored between the use of trees with hollows by 16 radio-tracked T. caninus and a range of measures of the morphological characteristics of the 113 different den trees they occupied. The results of the analyses indicate that the most used trees contained a relatively large number of cavities and were not surrounded by dense vegetation. Male possums were found most frequently in the southern part of the 35-ha study area, and females were found most often in the northern part.

Hollows in living or dead trees are an important resource for a range of animal species in Australia. They are used for diurnal and nocturnal shelter and as breeding sites, and the availability of hollows may be a limiting factor for some populations. This study examined patterns in the distribution of tree hollows at 185 sites, each of 1.0 ha, in remnant woodlands across the northern plains, Victoria, a rural region where little remains of the natural woodland cover. Spatial and temporal variation in the abundance of tree hollows is evident at several scales including that of the individual tree, the landscape and the region. For individual trees, the number of holes increased with tree diameter, and the slope of this relationship differed between tree species. The percentage of trees that are hollow-bearing also differs between species. Large trees have a higher proportion of holes with a large entrance diameter (>10 cm) and a lower proportion of small holes (?2 cm diameter) than do small trees. At the landscape scale, hollow-bearing trees were not evenly distributed throughout remnant woodlands. Significant variables in a regression model of the abundance of hollow-bearing trees included: the number of large trees (>70 cms diameter), woodland tree species composition and mean annual rainfall. At the regional scale, the availability of hollows is influenced by the patchy distribution of remnant woodlands. Large tracts are mainly associated with public land along river systems and contrast with extensive areas of farmland where woodlands are sparse or absent. The abundance of hollows at the landscape and regional scale is strongly influenced by the impact of land management on two key processes; the loss of existing hollow-bearing trees and the recruitment of new trees. On privately managed land, generally grazed by domestic stock, large trees with hollows are often present, but the scarcity of saplings and small trees raises concern over the recruitment of future hollow-bearing trees, and indeed the long-term persistence of woodland vegetation. Conversely, most sites in large blocks of public land have ample regeneration but relatively fewer hollow-bearing trees due to the loss of larger trees from timber harvesting activities. In both situations, the abundance of trees with hollows is the consequence of management practices, and their future availability is directly amenable to management action. Some implications of the patterns of distribution of hollows for wildlife are discussed.

On any given night in Victoria, around 4,000 children and young people live under the care and protection of the State. For many young people, this care extends over a long period of time, sometimes until their 18th birthday. It is well documented that young people leaving State care often lack the social and economic resources to assist them in making the transition into independent living. As a consequence, the long-term life outcomes from this group are frequently very poor. A recent report from the Centre for Excellence in Child and Family Welfare in partnership with Monash University estimated that, for a typical cohort of 450 young people who leave care in Victoria each year, the direct cost to the State resulting from these poor outcomes is $332.5 million. The estimated average outcomes of the leaving care population are based on a recent survey involving sixty young people who had spent at least two years in care as teenagers. This paper provides an overview of the economic methodology used to estimate this cost, and provides discussion of the motivation for measuring outcomes in terms of costs to the State.

The aim of the investigation is to evaluate the influence of different rootstocks on the flowering intensity of two plum cultivars: a hybrid `Kubanskaya Kometa` and European plum ‘Victoria’ in diverse locations. Sixteen well known European rootstocks were used, of which eight were clonal (St. Julien A, Brompton, Ackermann, Pixy, GF8/1, G5/22, GF655/2, Hamyra) and eight were seedlings (St. Julien INRA2, St. Julien d Orleans, St. Julien Noir, Brompton, Wangenheims Zwetche, St. Julien Wädenswil, Myrobalan, P. cerasifera var. divaricata). The evaluation was conducted in experimental orchards which were established in spring 2001 in Latvia, Estonia and Belarus. Trees were planted at a spacing of 5 × 3 m in four replications, three trees per plot. The obtained data from the years 2008-2012 are presented. The flowering intensity of plum trees depended on the cultivar rootstock combination. The influence of rootstock on flowering intensity differed between the years and growing region, and was closely correlates with meteorological conditions during the wintering period. Cv. ‘Kometa Kubanskaya’ had the highest blooming intensity in Pûre on rootstocks GF 655/2 and Wangenheims Zwetche; in Brest on Brompton seedlings, Julien d’ Orleans G5/22 and Ackermann; and in Polli on GF 8/1 and Brompton seedlings. ‘Victoria’ plum trees had the highest intensity of flowering on rootstocks Pixy and Wangenheims Zwetche in Pūre; on St. Julien INRA 2 and Ackermann in Brest; and on GF 655/2 and Ackermann in Polli.

Large trees with hollows are an important component of stand structural complexity worldwide. Understanding their population dynamics is needed to manage cavity-dependent biota. We quantified long-term rates of collapse of 302 measured trees with hollows in 1939-aged regrowth mountain ash ( Eucalyptus regnans F. Muell.) forest in southeastern Australia. We identified time-dependent dynamics in which the collapse rates of trees slowed from ∼4% annually between 1983 and 1993 to ∼2.2% between 1993 and 2007. Transitions of trees between different decay states (forms) also slowed over time. Nevertheless, during the 24-year period of our study, over half of our marked and measured trees had fallen, but there was no recruitment of new trees with hollows. Under current projections, few trees with hollows will occur on our field sites by ∼2050, although more had been forecast in earlier investigations. Such a paucity of trees with hollows in extensive areas of regrowth mountain ash forests will lead to a shortage of nesting and sheltering sites for cavity-dependent biota. We suggest a short–medium (10- to 100-year) focus on the conservation of old growth and multi-aged stands will be needed to maintain populations of those species strongly associated with trees with hollows in mountain ash forests.

Tree species selection was studied in free-ranging populations of koalas [Phascolarctos cinereus] on Phillip Island and the Brisbane Ranges in Victoria. At both sites koalas were found mainly on Eucalyptus spp. but occasionally used Acacia spp. Although koalas occurred on most of the Eucalyptus spp. present, both populations showed preferences for one or two species, particularly E. viminalis. Individual koalas showed different preferences, but the majority preferred E. viminalis. Some occurred exclusively on other species even when E. viminalis was close by. Koalas also showed preference for individual trees within a species.

A study was made of the use of trees with hollows by 10 adult male and 6 adult female mountain brushtail possums (Trichosurus caninus) at a 35-ha site in central Victoria, south-eastern Australia. Radio-tracking was used to identify which trees were being used as den sites by animals during an 18-month period between September 1990 and March 1992. Analyses of the data showed that, although 113 different trees were used by the 16 animals, most were occupied infrequently. The total number of trees used by a given animal ranged from 5 to 23. However, the majority of individuals spent most of their time denning in 1-3 trees. Of the 113 den trees, 70 were found to have been used by only 1 animal, 54 trees were used exclusively by males, and 28 trees by females only. Twelve trees were used extensively (on >40 occasions) but only 1 was used extensively by both sexes. Most of the T. caninus radio-tracked typically used 2 or more nest trees per week, indicating that animals moved frequently between den sites. Some animals used up to 6 different trees per week. Some possible reasons for this behaviour in T. caninus are discussed.

Spiralling medical costs and escalating demand for health services are putting primary care reform firmly on the agenda for governments around the world. A more coordinated and prevention-oriented approach must be adopted now to avoid a looming crisis in health care. In Victoria, the Primary Care Partnership (PCP) Strategy aims to improve health outcomes and better manage the demand for services by functionally integrating health and community support services. This paper provides an overview of the key factors that have shaped primary care reform in the State of Victoria; the logic of the PCP Strategy; a summary of the results of the strategy after 18 months; and a critical assessment of the key challenges for the strategy in the future. The paper concludes that the strategy has already led to much stronger collaboration between agencies, more integrated service planning and emerging models for service coordination. For these achievements to translate to improved health outcomes, the systems changes being initiated by PCPs need to be translated into the way services are provided in the community. This cannot be achieved by collaboration between service providers alone. It is now time for all relevant parts of government to support PCP objectives and initiatives in the way they plan and fund services.

The role of biotic agents in the dieback syndrome Mundulla Yellows (MY) was investigated by analysis of 40 Eucalyptus camaldulensis, E. leucoxylon, or E. cladocalyx trees and soil samples from South Australia and Victoria, Australia. No pathogenic fungi, bacteria, phytoplasmas, or insect pests or vectors were found to be associated with MY. However, nematode analysis identified Merlinius spp. to be associated with soil, but not roots, from symptomatic trees. Interveinal chlorosis symptoms were not transmissible by seed, mechanical inoculation, or grafting using plant material derived from symptomatic trees. Virus-like particles were detected at a single symptomatic study site using transmission electron microscopy. MY symptoms were induced in E. camaldulensis seedlings by sowing seed from asymptomatic trees into sterilized and unsterilized soil collected from underneath symptomatic trees. Significantly, sterilized soil induced more severe symptoms in seedlings than unsterilized soil. Soil collected from under asymptomatic trees did not induce MY symptoms. This preliminary investigation indicates that, with the exception of Merlinius spp., pathogenic organisms and pests were not consistently associated with MY symptoms.

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.

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.

The foraging ecology of the Swift Parrot Lathamus discolor in the box-ironbark forests and woodlands of Victoria was investigated over three years. We sought to identify features that characterized Swift Parrot foraging habitats. A total of 159 foraging sites was found, mainly in box-ironbark forests or nearby woodlands, and were located at a disproportionately high frequency on drainage lines, and a correspondingly low frequency on ridges. The species was observed foraging on 12 eucalypt and one Acacia species, but more than 90% of observations were of birds using Red Ironbark Eucalyptus tricarpa, Mugga Ironbark E. sideroxylon, Yellow Gum E. leucoxylon or Grey Box E. microcarpa. Nectar, lerp and other food from eucalypt foliage were frequent dietary items. Foraging and random sites were broadly similar in tree size-class structure. However, Swift Parrots selected trees in larger size classes for foraging more often than expected given the relative abundance of such trees. Larger trees flowered more reliably across the study area in all years. The habitat of the Swift Parrot in the study area is extensively fragmented and degraded, and management to increase the density of larger trees is recommended. We found considerable between-year variation in regional distribution and relative use of prinCipal tree species. The five identified regions within the study area all supported a significant percentage of the population in at least one of the three years. As a result, recovery measures will need to target important sites across the geographical extent of the study area.

Objective: To describe the characteristics of people under 60 years of age living in residential aged care in Victoria and to examine the occupational participation of younger residents in aged care facilities by measuring their social contact, participation in recreation and community access. Methods: A survey was sent to the Directors of Nursing at all 803 Commonwealth Department of Health and Aged Care registered aged care facilities in Victoria. Results: The survey had a 78% response rate and information was provided about the characteristics of 330 people under 60 years with high clinical needs residing in aged care facilities. This sample was extremely isolated from peers, with 44% receiving a visit from a friend less often than once per year. Sixteen per cent of residents participated in a recreation activity less than once per month and 21% went outside less than once per month. Of the sample, 34% almost never participated in any community-based activities such as shopping, leisure or visiting friends and family. Conclusion: Over one third of younger people in aged care are effectively excluded from life in our community. Most younger residents are socially isolated and have limited opportunities for recreation. Placement of younger people in aged care facilities is inappropriate, and alternative care models and settings are required.

There is growing evidence to support our understanding of adolescent violence in the home, however, there is a paucity of research about child-perpetrated violence that occurs within the context of kinship care. In 2017, Baptcare commenced research with 101 kinship carers in Victoria to gain a better understanding of how family violence was impacting on children and families. This research included a focus on child-perpetrated violence directed towards carers once the kinship placement commenced. In this context, family violence means any act of physical violence, emotional/psychological violence, verbal abuse and property damage caused by the child. This study utilised an online survey and semi-structured interviews that specifically targeted kinship carers who had direct experience of family violence. Findings demonstrated the disturbing types of child-perpetrated violent and aggressive behaviours kinship carers experienced. The data indicates that incidents of violence occurred early in the placement, they occurred frequently, and carers experienced multiple acts of violence from the child. The impact of the violence on the carer's household is significant in terms of the carer's health, wellbeing and placement stability. Further, the findings highlight the transgenerational nature of family violence in the context of kinship care in Victoria. The study described in this paper is the first step in understanding and exposing this complex issue and draws attention to some of the significant issues confronting Victorian kinship families experiencing family violence. This paper will describe the approach that Baptcare is taking to address family violence in its kinship-care programs.
