This article reviews two approaches—the Collar et al. (1994) global study of threatened bird species and Garnett's (1992b) analysis for Australia. Each of these studies uses IUCN ‘extinction risk threshold’ criteria to derive conservation ‘hotspots’ where effort should be concentrated. Difficulties with IUCN rankings stem from two implicit assumptions: (i) that the conservation objective is always to maximise the number of surviving taxa and (ii) that conservation in different ‘hotspots’ is equally costly. Garnett attempts to circumvent these limiting assumptions by supposing lexicographic conservation preferences. This is partly successful but still leads to prioritisation anomalies.","PeriodicalId":425760,"journal":{"name":"Australian Journal of Environmental Management","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126141316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For environmental benefits and costs that are non-marketed, this requirement presents numerous challenges. Choice Modelling shows particular promise in meeting these challenges. A case study involving the rehabilitation of the Macquarie Marshes in central western New South Wales is used to demonstrate how Choice Modelling can generate implicit prices for the individual attributes of wetland rehabilitation projects as well as estimates of the environmental benefits that will be created.","PeriodicalId":425760,"journal":{"name":"Australian Journal of Environmental Management","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115203368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PV, STE and wind have immense resources and small environmental impacts even when deployed on very large scales. They are the only fully sustainable technologies able to completely replace fossil and nuclear electricity generation during this century. Wind energy is now a low cost generation technology, and is likely to provide 10 per cent of the world's electricity by 2020. PV has found attractive niche markets and has an annual growth rate of 30 per cent per year. STE is a promising technology but presently lacks niche markets to enable an industry to get started. The Australian Government is offering attractive assistance for renewables, although the lack of research & development funding in these programs is a serious shortcoming.","PeriodicalId":425760,"journal":{"name":"Australian Journal of Environmental Management","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130191124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This resource has severely declined in recent years with even the survival of several fish species being threatened. There is currently little coordination of Australia s freshwater fisheries management and research is dominated by perceptions in individual States or Territories. Water and land management agencies, other than those with specific responsibility for fisheries, influence the major issues impacting the sustainability of freshwater fisheries. This article identifies and prioritises the six major threats to the sustainability of Australia's freshwater fisheries resource, based on information gathered from one survey and two expert panels, and suggests research needed to address those threats. The major threats are (1) habitat degradation, (2) pollution, (3) reduced environmental flows, (4) barriers to migration, (5) introduced species and (6) fishing. The commonality of research needs between these six threats and within components of each major threat is stressed. Greater coordination of fisheries, water and land management agencies both between and within States and Territories is required.","PeriodicalId":425760,"journal":{"name":"Australian Journal of Environmental Management","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127688436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there has been little attention given to the issue of local government and biodiversity conservation. The objective of this study was to assist Coffs Harbour City Council interpret a draft Plan of Management for koalas within its borders. The study was designed to answer two questions: 1) What will be the economic impact on residents of the requirement to abide by New South Wales state environmental planning policy to conserve koalas (SEPP 44), by way of individual development approvals; and 2) What will be the economic impact on residents of implementing SEPP 44 by way of a shire-wide Plan of Management. A comparison of the costs and benefits of a shire-wide plan shows that the benefits were more than double those of the costs of piecemeal decision-making, i.e. a decision after a development application has been lodged. Thus, a strategic approach is cost-efficient. The success of this work should provide an impetus for other councils currently considering whether to adopt a shire-wide program for conserving remnant koala habitat on private lands within their jurisdiction.","PeriodicalId":425760,"journal":{"name":"Australian Journal of Environmental Management","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122957659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The apparent success of Landcare has seen groups become an important delivery mechanism for the Natural Heritage Trust and other initiatives. In this article the author draws upon research in Victoria to argue that we are approaching the limits of what can realistically be expected of Landcare groups. Data were derived from state-wide surveys of Victorian groups between 1991 and 1998 and three 1999 regional case-studies in Corangamite, Glenelg and Goulburn/Broken. Survey data highlighted the extent most groups were operating at historically high activity levels and established a significant positive relationship between activity and government funding. Landcare work takes time and energy, particularly for group leaders, and given existing commitments to work, family and other volunteer organisations, it seems unlikely that current activity levels are sustainable. Survey data highlighted important program management issues that must be addressed as part of a more coherent and determined approach to supporting Landcare.","PeriodicalId":425760,"journal":{"name":"Australian Journal of Environmental Management","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131127183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
