The CHI was designed for the assessment of stream health by tangata whenua who wish to exercise kaitiakitanga over their rivers and streams and work with resource managers to achieve an improvement in the health of the resource. The objective was to provide a relatively straight–forward yet reliable measurement that can be repeated at regular intervals.
Decisions about ongoing monitoring will be determined by the purpose of applying the CHI. Usually follow–up is important. Creating a record (from both CHI scores and the associated photographic record) of cultural health over time will allow trends in the health of the streams and rivers within your rohe to be identified and monitored.
To monitor stream health over time, data must be gathered in a consistent manner and on a regular basis. It must be stored in a way that it can be easily retrieved and compared to newly gathered data.
The timing of repeat assessments is important to capture trends. Stream sites should be monitored at the same time each year and preferably during the summer when stream health is likely to be under the most pressure. If monitoring is required on an annual or two yearly basis, a monitoring plan can be developed. This will ensure that the team is ready to assess the sites at the right time of the year, as laid out in the schedule.
The ongoing use of the CHI has many benefits and can link to a range of other activities your hapū or iwi may be involved in.
