Notes on this study

The value is described in the wtp question as an improvement in biodiversity in native forest areas. The information provided in the survey was that, "There are important biodiversity values associated with the native forests which provide habitat for over 200 rare, endangered or vulnerable plant and animal species. The areas of native forest have high habitat and connectivity value because the overall area of remnant vegetation in the Mt Lofty Ranges is limited." The improvement is achieved by reducing the area of native forest under threat from weeds and pests by 20%, where the current area under threat is 60-70%.

Notes on this study

Colonial waterbird breeding now occurs in some wetlands along the Murray one in every 10 years. The levels presented to survey respondents are improvement to the 1 in 10 frequency. Respondents were told each option has an annual household cost that will be paid each year for a 10-year period through increased taxes and higher prices for food.
