Abstract:
The first empirical application of an established framework for evaluating the adaptive efficiency of policy and project options — the Institutional Cost-Effectiveness Analysis (ICEA) framework — is documented in this paper. The application involves cost-effectiveness comparison of six projects for environmental water recovery in the Murray-Darling Basin, Australia, managed by the New South Wales (NSW) Government under three programs: The Living Murray Initiative; the NSW Wetland Recovery Program; and the NSW Rivers Environmental Restoration Program. Focussing primarily on one of the projects — the Darling Anabranch Pipeline Project (DAPP) — allows an in-depth account to be presented of the ICEA framework’s application. Abatement and transaction costs, and public and private subsets of these costs, were accounted for in the applications. The adaptive efficiency of the DAPP (a “water-saving project”) is found provisionally — i.e., without accounting quantitatively for institutional lock-in costs — to exceed that of the five other environmental water recovery projects (including two “market-purchase projects”) evaluated. This finding is significant given a tendency for economists to presume that environmental water recovery is generally achieved more efficiently through market-purchase projects. With water management, and environmental management more broadly, exposed to increasing uncertainty, adaptive efficiency will grow in importance as a metric for economic evaluation. The application of the ICEA framework documented in this paper can guide researchers in applying this metric to evaluations of projects and policies implemented in, or proposed for, this domain.

Abstract:
Relatively few large-scale inventories of the world's wetlands exist because of the difficulties of spatial scale, associated cost and multiple objectives, often temporally confounded, that drive classification. The extent of wetlands across a large part of Australia (New South Wales, 80.6 million ha) was determined using satellite image analyses. These data allowed analyses of the distribution of wetlands, their conservation status and potential threats at different spatial scales; that is, State, coastal and inland, and catchment. Approximately 5.6% of New South Wales is wetland (4.5 million ha), mostly (96%) in inland river catchments. Broad classification allowed identification of the extent of wetland types: (i) floodplains (89%); (ii) freshwater lakes (6.6%); (iii) saline lakes (< 1%); (iv) estuarine wetlands (2.5%); and (v) coastal lagoons and lakes (1.5%). Conservation reserves protect only 3% of wetland area. The analyses identified the north-west as the key area for wetland conservation as most other catchments have lower wetland extent and more potential threatening processes. The first stage of a large-scale inventory is to determine the extent and location of wetlands, with immediate benefits for strategic conservation and management. Other objectives (e.g. classification, biotic composition, hydrology and threats) seldom have sufficient data available for large-scale inventories but can be completed later with resources.

Abstract:
A modular series of vertical flow wetland (VFW) systems was established in 1989/90 to treat up to 130,000 litres per day of primary settled sewage on the north coast of New South Wales, Australia as an experimental scale-up of wetland microcosms that had been developed with this hydrological format. Monitoring of inflow and outflow water quality was maintained on a weekly basis from January 1991 to February 1992. Some management parameters (e.g. flow rates) were varied during this period. Dye injection to examine hydraulic behaviour within the gravel bed was carried out on two occasions in one VFW. In general the removal of nutrients was lower than expected, with between 20% and 40% reduction in concentrations and removal of loads over the year. Suspended solids and BOD removals were excellent, with a surprisingly good reduction in faecal coliform counts as well. Reduction in flow rates improved performance markedly in all parameters.

Abstract:
Wetlands experience fluctuating water levels, so their extent varies spatially and temporally. This characteristic is widespread and likely to increase as global temperatures and evaporation rates increase. The temporary nature of wetlands can confound where a wetland begins and ends, resulting in unreliable mapping and determination of wetland areas for inventory, planning or monitoring purposes. The occurrence of plants that rely on the presence of water for part or all of their life history can be a reliable way to determine the extent of water-affected ecosystems. A wetland plant indicator list (WPIL) could enable more accurate mapping and provide a tool for on-ground validation of wetland boundaries. However, this introduces the problem of the definition of ‘wetland plant’, especially with species that can tolerate, or require, water level fluctuation, and that respond to flooding or drought by adjusting their morphology or phenology (i.e. ‘amphibious’ plants and those that grow only during drawdown). In this study we developed a WPIL through a process of expert elicitation. The expert decisions were compared and standardised for each species. It is envisaged that this work will lead to a comprehensive listing of wetland plants for Australia for the purposes of planning, mapping and management.

Abstract:
The overall aim of this study was to investigate structures of bird communities in remnants of fragmented box/cypress pine woodlands in central New South Wales, Australia, to guide habitat rehabilitation. The aims of the study were to: (1) determine how bird densities and species richness varied with remnant category; (2) determine how ranked densities of bird species varied by feeding group with remnant category; and (3) provide information on structures of bird communities in box/cypress pine woodlands to guide restoration. Structures of bird communities varied with remnant category. Large remnants had the most species whereas medium-sized and small remnants in low condition had the fewest. Bird densities increased with decreasing remnant area although densities did not differ significantly between remnant categories. Ranked bird densities varied between remnant categories, with relatively even distributions in large remnants in high condition, and uneven distributions in small remnants in low condition. Densities of small insectivores were much lower in small, low-condition remnants than in large, high-condition remnants. Densities of generalists such as noisy miner and galah showed the reverse pattern. The structures of bird communities in large remnants in good condition provide a reference state for assessing recovery of bird communities.

Abstract:
Alligator weed is a serious weed in many countries. In Australia, it is a “weed of national significance” because of its actual and potential impact. We surveyed all local governments in New South Wales in 2001 and 2007 to determine whether the weed is being contained. We found an increased number and extent of infestations, despite more resources and a better knowledge base. Most considered that further research is needed in tactics for control of the weed. On the basis of current containment in urban gardens, we recommend that governments better mobilize the community (e.g., bush restoration consultants, Landcare groups) to deal with alligator weed infestations.

Abstract:
Grassland communities worldwide have been extensively modified or lost following broadscale agricultural expansion. In south-eastern Australia few natural grasslands remain, with most now being small, isolated and degraded. Conservation and restoration of grassland communities requires an understanding of the impacts of fragmentation on genetic and demographic processes. Swainsona sericea is a perennial grassland herb with conservation listing in New South Wales, Victoria and South Australia. Reproductive output, progeny fitness and genetic diversity were assessed in nine S. sericea populations occupying fragmented grasslands across the southern tablelands of New South Wales. Unexpectedly, four chromosome classes were observed among the populations (2n = 4x = 32, 2n = 10x = 80, 2n = 14x = 112, 2n = 16x = 128), suggesting a more complex taxonomy than is currently recognised. There was no association between reproductive output and population size or ploidy level whereas population size influenced the number of alleles and percentage of polymorphic loci while ploidy influenced effective alleles and expected heterozygosity. Restricted maximum likelihood analyses of progeny growth indicated that ploidy had a significant influence on height, shoot weight, shoot to root ratio and days to germination. The cytological complexity in S. sericea requires clarification, including delineating the cytological boundaries to enable land managers to include this in their conservation and management plans.

Abstract:
Intertidal wetland habitats in southeastern Australia have changed significantly during the past sixty years. Mangrove habitats have expanded both seawards and landwards, the latter being at the expense of saltmarsh habitats. This relatively common phenomenon is generally suggested to be an outcome of sea-level rise. Several factors potentially responsible for this change are examined, including changes in mean sealevel during the past 50 to 100 years, changes in climate, population growth, catchment landuse, and estuary type. A protocol for mapping estuarine habitats was developed and implemented, incorporating the application of geographic information systems. Spatial and temporal coastal wetland habitat changes at nine sites along the New South Wales coast are illustrated. These habitat dynamics were shown to not correlate between sites. The results demonstrate that sea-level rise in this region cannot solely account for the extent of change during the past sixty years. With the exception of one site (Careel Bay), there have been no correlations between contemporary mean sea-level rise and mangrove incursion of the saltmarsh habitats at the study sites, or with rainfall patterns, at the scale of observation in this study, which was largely decadal. The only correlations determined during this study have been between population growth and coastal wetland habitat dynamics in some sites. In spite of saltmarsh habitat loss being a regional phenomenon, local factors appear to have a profound bearing on the rates of change. Neither contemporary mean sea-level rise, rainfall patterns, estuary type, catchment landuse, catchment natural cover nor population pressure can account solely for the patterns in the spatial and temporal dynamics of the coastal wetlands of New South Wales. It seems apparent that regional factors create preconditions favourable for mangrove incursion, but that localised conditions have been responsible for the extent of these incursions from site to site. That is, despite higher sea-level and greater rainfall, the extent of change has been determined by the unique characteristics of each site. The results have important implications for current estuary management practices in the state of New South Wales. The lack of spatial and temporal trends in coastal wetland habitat dynamics point to the need for management to be conducted on a localised, rather than regional scale. Additionally, anthropogenic influences must be carefully managed, since the extent of mangrove habitat expansion into saltmarsh areas is unlikely to be a natural occurrence.

Abstract:
Rainforest Restoration Manual for South-Eastern Australia is the definitive guide to the recovery and restoration of Subtropical, Warm Temperate, Cool Temperate, Gallery, Dry, Dry Gully and Littoral Rainforests from south-eastern Queensland to Tasmania. All of these rainforest types were inherently rare prior to settlement, and today with depletion, feral animals, weeds and climate change, all are threatened – with many listed under state and federal legislation. The manual presents detailed restoration methods in 10 easy-to-follow steps, documenting the research and trials undertaken during rainforest restoration over more than two decades. These experiments and their results will empower readers to uncover answers to many of the problems they could encounter. The manual is supported by a CD that provides important background information, with 32 appendices, a propagation manual for the region's 735 rainforest plants, an illustrated glossary and resources for teachers. Species lists and specific planting guides are provided for the 57 rainforest floristic communities that occur from the coast to the mountains between Durras Mountain in New South Wales and the Otways in Victoria. Extensively illustrated with colour photographs, this book will empower you or your group to be able to restore, manage, protect and conserve the magnificent rainforests that are in your care. The general principles and techniques described will meet the needs of students and teachers, novices, experienced practitioners, community groups and agencies alike.

Abstract:
<em>Abstract.</em>—Wood induces hydraulic, morphologic, and textural complexity into fluvial systems in forested regions around the world. Snags and logjams can create complex networks of channels and wetlands across entire river valleys and historically posed a significant obstacle to navigation. The clearing of wood from channels and riparian forest land reduced or eliminated the quantity and supply of wood into rivers in many regions of the world. Ecological restoration of fluvial environments increasingly includes the placement of wood. But few guidelines exist on appropriate methods for emulating natural wood accumulations, where and how to place wood, its longevity, the hydraulic and geomorphic consequences of wood, and how to manage systems where wood is reintroduced. Important factors to understand when placing wood in rivers include the watershed and reach-scale context of a project, the hydraulic and geomorphic effects of wood placements, possible changes in wood structures over time, and how it may impact human infrastructure and safety. Engineered logjams constructed in Washington, USA and New South Wales, Australia offer examples of how wood reintroduction can be engineered without the use of artificial anchoring to form stable instream structures as part of efforts to rehabilitate fluvial ecosystems and provide ecologically sensitive means to treat traditional problems such as bank stabilization and grade control.

Abstract:
<p>Asset managers are faced with the challenge of maintaining concrete structures in coastal environment, within the financial constraints of maintenance budget allocations, such that they remain functionally and structurally safe for the remainder of their design lives. For these reasons concrete remediation is fast becoming an important component of asset management in coastal areas. This research describes remediation techniques and practice currently being employed by prominent public and private organisations responsible for maintaining concrete structures in the Illawarra region (New South Wales, Australia). These common remediation techniques range from conventional restoration, cathodic protection and structural strengthening. The research also considers the underlying factors used to evaluate the effectiveness of these techniques and practices. A model of good practice for concrete remediation in the Illawarra is developed from the literature and industry research undertaken. This model is developed for concrete suffering deterioration caused by the corrosion of steel reinforcement and is aimed to provide intelligent concrete remediation options based on sound principles and industry knowledge.</p>
