Results of our stream restoration survey.

Prior to attempts of stream restoration, it is important to clearly define the major objectives of the intended project which may differ depending on the views of the interest groups driving or enacting the restoration.

To understand the diversity of views held by members of the public and special interest groups (e.g. regional council representatives, conservation groups) we carried out a survey to identify the major causes of poor stream health within the respondents region, the value given to different components of a typical stream ecosystem (e.g. birds, fish, vegetation, etc.) and the importance placed on different stream restoration objectives.

This report describes the outcome of this survey, which will be used to develop objectives for future stream restoration projects, recognising ecological function at all trophic levels.

Question 1. In stream restoration projects how important are the following issues to you/your organisation?

Respondents were least concerned about the economic and recreational benefits of stream restoration and favoured improvements for the benefit of water quality and ecology as well as for flood control. Equally important however, was the opportunity to engage with the community during stream

Question 2. In stream ecosystems, how important are the following components to the overall ecological health of the stream?

Respondents placed high values on all of the various components of stream ecology, with birdlife being rated slightly lower than the rest, including algae and microorganisms. This result is surprising as it has traditionally been assumed that community groups place greater value on the presence of larger

Question 3. What are the major causes of poor stream health in your area?

The results of this question reveal multiple causes of poor stream health within the respondents locality, with all factors except the disposal of public or private sewage scoring 5 or higher. All types of pollutants were suggested to be important factors affecting stream health as were the lack of riparian buffer

In summary, respondents generally considered the restoration of streams to be most important for flood control and to aid ecological recovery recognising the importance of all components of the stream ecosystem, including microorganisms. The threats to stream health were perceived to be broad ranging and included a wide-range of both urban and agricultural pollutants.
