Full textAbstract:
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 textAbstract:
Eucalyptus strzeleckii K.Rule (Strzelecki gum) is a medium to tall, forest swamp gum endemic to the foothills and flats of southern Victoria. It is listed as Vulnerable at State (Victoria) and Federal levels. Many of the existing populations are dominated by mature, senescing trees in highly degraded habitats and recruitment of the species is rarely observed. The present study assessed the natural recruitment of Strzelecki gum at locations where mature Strzelecki gums are present and habitat degradation is not a significant limiting factor. The number of mature and recruiting Strzelecki gum individuals was assessed within gradient-oriented belt transects (gradsects) and a range of variables considered to be likely to affect recruitment were measured and correlated with the results of the recruitment study. Strzelecki gum recruits (<5 m tall) were found in 68.8% of gradsects and recruits accounted for 8–14% of the total stems counted for this species. Areas that had been recently burnt (within the past 5 years) had 15 times the number of Strzelecki gum recruits. Disturbance by flooding may also be positively associated with recruitment. Litter cover, habitat quality and density of intermediate-sized Strzelecki gums were all strong positive predictors for the density of Strzelecki gum recruits. Results from the present survey have provided a basis for land managers to estimate quantities of mature and recruiting Strzelecki gums in large populations.

Full textAbstract:
A list of 37 species of ptyctimous mites from the State of Victoria, Australia, is provided. Seven species new for science are described and further seven are recorded for the first time in Victoria. The genus Arphthicarus has been discovered in Victoria and is represented by two new species. Zoogeographical distribution of each species is provided. Analysis of the ptyctimous fauna from four Victorian areas (Otway Ranges, Yarra Ranges, Errinundra Plateau and Strzelecki Ranges) has revealed that four species occur in a large number of specimens in one of the areas. Similarity analyses indicate that the faunas of Errinundra Plateau and Yarra Ranges are the most similar. An overview of state of knowledge on the ptyctimous mites from State of Victoria, Australia and Australasian Region is presented.

Full textAbstract:
Eucalyptus strzeleckii K. Rule (Strzelecki gum) is a medium-to-tall forest swamp gum, endemic to Victoria and listed as Nationally Vulnerable in Australia. This species occurs in the high rainfall (up to 1600 mm) region of Gippsland in south-eastern Victoria. The region has been intensively developed for agriculture, in particular dairy production. Surviving trees are often old and in varying stages of dieback and natural recruitment is rarely observed. The removal of cattle-grazing as a sole mechanism to encourage recruitment is rarely sufficient to promote regeneration of this species. The aim of this study was to examine the role of soil disturbance, weed competition, seed supply and parent plant competition, in the absence of cattle-grazing, in the recruitment of E. strzeleckii. Seed availability, distance from mature tree, soil disturbance, soil moisture and pasture competition all influenced seedling establishment and survival in the field. Removal of ground layer vegetation immediately before seedling emergence appears to be essential for successful establishment of E. strzeleckii. However, both soil disturbance and pasture removal by spraying had similar effects, suggesting that competition rather than soil disturbance per se is a limiting factor in these environments. In the absence of understorey vegetation manipulation, regeneration by this species is unlikely even in the absence of grazing.

Full textAbstract:
Abstract This study considered the degree of genetic variation for diameter (DBH), basic density (BD), predicted pulp yield (PPY), fibre length (FL), microfibril angle (MFA) and cellulose content (CC) amongst eight subraces of Eucalyptus globulus growing in a field trial in NW Tasmania. There were significant subrace effects for BD, FL and CC. This variation affected the relative profitability of the subraces for pulp production. On average, the most profitable subraces (on NPV/ha over the base population mean) were Strzelecki Ranges ($862.04), Western Otways ($657.80) and Strzelecki Foothills ($576.81). The genetic control (heritability) of variation in DBH, FL and MFA was moderate (0.15 < h2< 0.27), while control for BD, PPY and CC was high (h2> 0.40). Genetic correlations between growth and wood properties were not statistically significant, except for DBHMFA (-0.86). Most genetic correlations amongst wood properties were outside the parametric space (< -1 or >1), but there were significant correlations between BDMFA (-0.70) and PPY-CC (0.82). The empirical response to selection on an index based on a pulp wood objective (which included volume and basic density) resulted in a gain of 4.3% for DBH, 7.9% for BD and marginal changes for all other traits, with a net impact in profit of $1,270/ha. However, future profit calculations will need to consider the effect of FL, MFA and CC on the economics of wood processing to fully evaluate the economic impact of breeding.

Full textAbstract:
The rate and spatial scale at which natural environments are being modified by human land-uses mean that a regional or national perspective is necessary to understand the status of the native biota. Here, we outline a landscape-based approach for using data from the ‘New Atlas of Australian Birds’ to examine the distribution and status of avifauna at a regional scale. We use data from two bioregions in south-east Australia – the Gippsland Plain and the Strzelecki Ranges (collectively termed the greater Gippsland Plains) – to demonstrate this approach. Records were compiled for 57 landscape units, each 10′ latitude by 10′ longitude (~270 km2) across the study region. A total of 165 terrestrial bird species was recorded from 1870 ‘area searches’, with a further 24 species added from incidental observations and other surveys. Of these, 108 species were considered ‘typical’ of the greater Gippsland Plain in that they currently or historically occur regularly in the study region. An index of species ‘occurrence’, combining reporting rate and breadth of distribution, was used to identify rare, common, widespread and restricted species. Ordination of the dataset highlighted assemblages of birds that had similar spatial distributions. A complementarity analysis identified a subset of 14 landscape units that together contained records from at least three different landscape units for each of the 108 ‘typical’ species. When compared with the 40 most common ‘typical’ species, the 40 least common species were more likely to be forest specialists, nest on the ground and, owing to the prevalence of raptors in the least common group, take prey on the wing. The future status of the terrestrial avifauna of the greater Gippsland Plains will depend on the extent to which effective restoration actions can be undertaken to ensure adequate representation of habitats for all species, especially for the large number of species of conservation concern.

Full textAbstract:
The complete geographic range of Eucalyptus nitens s. lat. (shining gum) was sampled to determine the pattern of variation in adult and seedling morphology. Analyses of the different data sets indicated the presence of two distinct taxa: one, characterised by denticulate adult leaf margins, is described as E. denticulata sp. nov.; the other, characterised by entire leaf margins, is E. nitens s. str. Many other characters distinguish the two taxa. Mature trees of E. denticulata have leaves with higher oil gland density, longer peduncles, more cup-shaped rather than barrel-shaped fruit, more frequently exserted valves, and rounded and longer flower buds compared with E. nitens s. str. Seedlings of the two species can be distinguished mainly on the basis that those of E. denticulata have longer internodes and leaves which clasp the stem to a lesser extent. The major occurrence of E. denticulata is on the Errinundra Plateau, East Gippsland, with limited occurrences in the Baw Baw Ranges and Central Highlands of Victoria. Eucalyptus nitens s. str. is found in isolated stands in New South Wales and Victoria. The two species are allopatric, with the exception of the Baw Baw Ranges and Central Highlands of Victoria where some stands are mixed. Eucalyptus nitens s. str. is also geographically variable, comprising three distinct geographic races: northern and central New South Wales, southern New South Wales, and the Baw Baw Ranges and Central Highlands of Victoria.

"Identification of key environmental variables associated with the presence of Toothed Leionema (Leionema bilobum serrulatum) in the Strzelecki Ranges, Victoria, Australia." Australian Journal of Botany 59, no. 3 (2011): 207. http://dx.doi.org/10.1071/bt10197.
Full textAbstract:
Toothed Leionema is one of four subspecies of Leionema bilobum from the Rutaceae family. A dense shrub or small tree, growing to ~4 m high, it is a poorly investigated species which is considered rare in Victoria, Australia. This paper presents the results of a study using Geographical Information Systems and Weights-of-Evidence predictive modelling to assess the importance of seven environmental factors in determining habitat suitability for this species in the Strzelecki Ranges, Victoria. This method is particularly useful in understanding the distribution of rare species, especially where the ecology of the species of interest is not well understood. Of the seven environmental factors considered here, four were found to be important: elevation, aspect, distance to water and distance to plantation (disturbed) areas. The modelling results indicate that areas with elevations between 350 and 550 m and a dominant south-western aspect that are close to plantation areas (within 700 m), and to water (within 1100–1200 m), provide potentially suitable habitat for Toothed Leionema in the region.

Full textAbstract:
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.

Full textAbstract:
The intensive nature of land uses in the Strzelecki Ranges poses significant threats to landscape values and water quality. A comprehensive catchment strategy was developed based on sustainability science concepts incorporating the careful management of landscape values, proper land management approaches, and government policy and legislative change to ensure that agriculture, forestry and other land uses become sustainable in this sensitive environment. The readily measurable water quality indicators of turbidity, flow, electrical conductivity, and water temperature were used to determine the impacts of the major land uses in the Strzeleckis. From a water quality perspective, there was a trend of decreasing water quality with increasing intensity in land management. However, from a total sediment load perspective, the forest area contributed the highest total sediment load due to higher volumes of steam flow suggesting that natural processes in the Strzeleckis may remain the principal mechanisms for sediment movement within the catchment. An incidental but significant finding was extensive bioturbation along the riparian zone of the plantation area, the extent of which was not observed in the other catchments. This finding suggested that bioturbation may have been the most significant contributor to poorer water quality flowing from in the plantation catchment. The project developed insights into the major environmental processes active in the upper catchment of the Morwell River. Understanding of the contributions to total sediment loads from natural erosional processes and bioturbation, findings related to the impacts on water quality from agricultural practices, and encountering negligible impacts from conservative timber harvesting practices demonstrate that catchment management approaches need to be tailored to achieve sustainability in land uses across the landscape. Key recommendations include the re-establishment and protection of riparian zones in agricultural catchments, the careful assessment and setting of stream buffer zone widths for timber harvesting operations, and the need for further work to map the extent of natural processes such as bioturbation and stream bank erosion. To mitigate these issues, government policy and legislation will need to focus on the preservation and enhancement of the Crown land riparian zones. Recommended changes to current administrative land management arrangements for these sensitive areas include a move from licensing riparian zones for agricultural practices such as grazing to conservation.

Finding Australian Birds is a guide to the special birds found across Australia's vastly varied landscapes. From the eastern rainforests to central deserts, Australia is home to some 900 species of birds. This book covers over 400 Australian bird watching sites conveniently grouped into the best birding areas, from one end of the country to the other. This includes areas such as Kakadu in the Top End and rocky gorges in the central deserts of the Northern Territory, the Great Barrier Reef in Queensland, rainforests distributed along the eastern Australian seaboard, some of the world's tallest forests in Tasmania, the Flinders Ranges and deserts along the iconic Strzelecki and Birdsville Tracks in South Australia, and the mallee temperate woodlands and spectacular coastlines in both Victoria and south west Western Australia.
Each chapter begins with a brief description of the location, followed by a section on where to find the birds, which describes specific birdwatching sites within the location's boundaries, and information on accommodation and facilities. The book also provides a comprehensive 'Bird Finding Guide', listing all of Australia's birds with details on their abundance and where exactly to see them.
Of value to both Australian birdwatchers and international visitors, this book will assist novices, birders of intermediate skill and keen 'twitchers' to find any Australian species.
