This dashboard shows the results from macroinvertebrate sampling at this site. It displays three ecological indicators: macroinvertebrate community index, taxonomic richness and percent EPT.
For sites where State is 'N/A' or Trend is 'Not Assessed', there are not enough data to calculate a State and/or Trend result. Click on an indicator to see the available historical 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.
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 proposed national guidelines. Therefore, data collected at this site is following best practice.
Samples at this site have been processed following protocol P2 which is recommended by proposed national guidelines. 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.
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.
