Naturalness and Place in River Rehabilitation Ecology and Society
Fryirs, Kirstie; Macquarie University; kirstie.fryirs@els.mq.edu.au; Brierley, Gary J; University of Auckland; g.brierley@auckland.ac.nz.
An authentic approach to river rehabilitation emphasizes concerns for the natural values of a given place. As landscape considerations fashion the physical template upon which biotic associations take place, various geomorphic issues must be addressed in framing rehabilitation activities that strive to improve river health. An open-ended approach to river classification promotes applications that appreciate the values of a given river, rather than pigeonholing reality. As the geomorphic structure of some rivers is naturally simple, promoting heterogeneity as a basis for management may not always be appropriate. Efforts to protect unique attributes of river systems must be balanced with procedures that look after common features. Concerns for ecosystem...

Testing for value stability with a meta-analysis of choice experiments: River health in Australia AgEcon
Rolfe, John; Brouwer, Roy.
While meta-analysis is typically used to identify value estimates for benefit transfer, applications also provide insights into the potential influence of design, study and methodological factors on results of non-market valuation experiments. In this paper, a metaanalysis of sixteen separate choice modelling studies in Australia with 130 individual value estimates relating to river health are reported. The studies involved different measures and scales of river health, so consistency was generated by transforming implicit prices from each study into a common standard of WTP per kilometer of river in good health. Tobit models have been used to identify the relationships between the dependent variable (WTP/km) and a number of variables. The results...

Using Choice Experiments to value River and Estuary Health in Tasmania with Individual Preference Heterogeneity AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W..
Choice experiments (CE), also known as choice modelling (CM), are now used widely in environmental valuation in Australia. Many examples assess the trade-offs between river catchment management and socio-economic impacts. There is, however, limited information about the values of Australian estuaries and none of the existing valuation studies addresses catchment management changes in Tasmania. The CE study described in this report aims to elicit community preferences for protecting the rivers and estuary of the George catchment in north-eastern Tasmania. Results from conditional and mixed logit models show that respondents are, on average, willing to pay between $2.47 and $4.46 for a one kilometre increase in native riverside vegetation, and between...
