This dashboard shows the result of macroinvertebrate sampling at this site. It displays three measures, macroinvertebrate community index, taxanomic richness and percent EPT.
If 'N/A' is showing, there are not enough data to calculate a 5-year median. You can select the 'Show more information+' box under each measure to see the available historic data.
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.
For more details on each tick, see our 'Can I Trust this Data' Factsheet.
Macroinvertebrates are sampled at this site as part of council's stream health monitoring programme, as recommended by proposed national guidelines.
Macroinvertebrate sampling is done annually or more frequently at this site as recommended by proposed national guidelines. Therefore, data shown here follow current best practice guidelines.
This site is a hard-bottomed site and appropriate sampling protocols have been applied. Data shown here have been collected using current best-practice.
Macroinvertebrate sampling is done in riffle habitat at this site. Data shown here are therefore following best practice.
Macroinvertebrate samples are collected within the first two weeks after a flood greater than three times the median flow at this site. Proposed national guidelines suggest a minimum of two weeks 'stand-down' period after a flood greater than three times the median flow. Therefore, data shown here is not following best practice and conclusions based on this data need to be treated with caution.
Samples at this site have been processed following sampling protocol P1 (semi-quantitative - coded abundance). Data shown here is not following best practice, but are still robust.
Field data collected at this site had no quality control applied to it.
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.
