The Cawthron Institute has worked alongside regional councils to verify the processes and methods used for macroinvertebrate data collection, processing of the data in the laboratory, quality control in the field and laboratory and the statistical analysis and interpretation of the results presented.

This council does not monitor macroinvertebrates as part of their stream health monitoring.
This site is a hard-bottomed site and appropriate sampling protocols have been applied. Data shown here have been collected using current best-practice based on Stark et al. (2001).
Macroinvertebrate sampling is done in all meso-habitats (i.e., pool, run and riffle), rather than just in riffle habitat, as Stark et al. (2001) suggest. All-habitat sampling provides a more comprehensive description than riffle-only sampling of the invertebrate community at a stream site. However, comparisons made between macroinvertebrate data collected in all habitat and data collected in just riffle habitat need to be treated with caution.
This council does not collect any macroinvertebrate samples for up to two weeks after a flood greater than three times the median flow as recommended by Stark et al. (2001). Therefore, data collected at this site is following best practice.
Samples at this site have been processed following protocol P2 which is recommended by Stark et al. (2001). However, the individual count number has been reduced from 200 to 100 (with a scan for rare taxa). Data processed at this site are therefore not following best practice and conclusions based on this data need to be treated with caution.
Data collected at this site had some form of field quality control done.
Data processed at this site has had one of the three Laboratory Quality Control Protocols (i.e., QC1, QC2,Q C3) applied. Data shown here is more robust than data with no laboratory QC applied.
