Description and method logic

Method purpose

The State of the Rivers Survey was developed in Queensland, in response to a need for detailed information on the physical and environmental condition of streams and rivers. This information would then be available for use in the Integrated Catchment Management process.

The State of the Rivers Survey provides a 'snapshot' of the physical and environmental condition of streams and is not designed to establish the trend or rate of change of stream condition.

Summary

The State of the Rivers methodology provides a comprehensive method for assessing the current ecological and physical condition of rivers and streams. It uses a snapshot survey technique based on the notion of homogenous streams sections. The streams and rivers are successively divided into smaller and smaller sections until homogeneity is reached in terms of scale, natural features and condition. Finalising the boundaries and number of homogenous sections is an iterative process.

There are nine criteria headings based on 11 datasheets (some datasheets only contain positioning information).

Method logic

The field survey collects in-steam data on a number of components using rapid survey methods. Each component is assessed independently and given an objective condition rating. These ratings are combined to give an overall condition rating. A relative, rather than an absolute standard has been used to fix the benchmark condition used to derive the ratings. The condition rating assesses the extent to which the condition of the survey component has deteriorated from the local benchmark. Different standards may be used in different catchments.

The parameters recorded for each component are stored in linked databases. This allows data analysis and processing for follow-up work and investigations.

The State of the Rivers Survey was designed to 'estimate the ecological condition of rivers in terms of the condition of the instream habitat, rather than by conducting flora or faunal surveys'. The Survey primarily makes a detailed assessment of components that describe the physical condition of streams, such as channel habitat, bed condition, bank condition, cross-sectional dimension and riparian vegetation as habitat attributes of general importance to the biota are encompassed by these components are recognised. Many of the variables measured in the State of the Rivers Survey correspond with those measured in AusRivAS, River Habitat Survey (RHS) and Habitat Predictive Modelling. Empirical links between biota and habitat that are encompassed within other methods, may be represented by the variables collected in the State of the Rivers Survey.

Criteria groupings of the method

The method assesses ecological condition in terms of in-stream habitat rather than by conducting flora or fauna surveys and takes a 'snapshot' of the current condition of homogenous stream sections. Indicators are grouped into 9 Criteria (hydrology, bank condition, bed and bar condition, channel habitats, cross section, reach environs, vegetation, aquatic habitat and scenic, recreational and conservation values)

Data required

Eleven datasheets are used during the survey for each site covering subsection data (hydrology, bank condition, bed and bar condition, channel habitats, cross section, reach environs, vegetation, aquatic habitat and scenic, recreational and conservation values).

Resources required

Expertise required

This methodology requires survey teams trained in using the method in field, assessment and database management.

Materials required

1:25,000 and 1:100,000 maps, four-wheel drive, boat, survey equipment, GPS, camera, datasheets, vegetation keys, photo archive, database and GIS. Some desk based data collection also required.

Review

Recommended user

Government officers, catchment group members, NRM officers.

Strengths

  • Applicable throughout Queensland
  • Easily understood by users with varying backgrounds, experience and qualifications
  • Flexible, more sites can be surveyed in problem areas
  • Stand-alone but can interface with other databases and types of data.
  • Comprehensive coverage of stream sections within a catchment
  • Assessment of at many levels - whole catchment, individual sections or individual tributaries, using data components individually or together
  • Use of homogeneous stream sections allows extrapolation from the sampling scale to larger areas
  • Physical measurements indirectly represent geomorphological processes
  • Some empirical links between the parameters measured and stream biota (e.g. substratum, riparian vegetation)

Limitations

  • Doesn't include water quality
  • Does not in itself directly measure the rate of change or the trend
  • High level of expertise needed.
  • Comparisons to reference condition are subjective
  • Links between some measured parameters (e.g. bank condition, bar shape) and biota are not well established
  • Links between structure and process are weak
