Stock exclusion effort over time
Showing:What is this showing me?
This graph shows the stock exclusion actions recorded on the Healthy Waterways register – most commonly this is by fencing the waterway. The quantitative measure is the recorded length of waterway banks where stock have been excluded. The bars show the cumulative totals each year. Note that stock exclusion from wetlands is not included here but reported in the wetlands indicator.
We often lack historical data on actions, so the graphs represent efforts since 1999. For some indicators, the regional council has provided initial data based on surveys of stock exclusion or riparian planting in 1999.
What does the catchment journey tell us?
The catchment journey enables us to compare how much progress has been made in areas in this catchment that would benefit from the action shown. This allows us to see how a catchment compares with nearby or similar catchments. Ultimately, this length of journey information may help answer how far have we got to go? and also how much is enough? when used along with monitoring waterway health.
Approximately
78%
of river length, or 393 km of riverbanks run through farmland, where stock exclusion is an appropriate action.
How have we calculated catchment journey?
Healthy Waterways have used national datasets to get a consistent calculation using river bank length for stock exclusion and riparian planting, and land area for erosion and farm plans.
For each indicator, the calculation focuses on only those land uses for which the action is appropriate. The categories of land use are: forestry - exotic, forestry - indigenous, farm land, urban and other.
Sizing the journey
For assessing stock exclusion, the calculation is based on farmland areas only, and it excludes waterways in indigenous forests, exotic forests, or urban areas. The length of stock exclusion actions is compared against the total riverbank length (includes both sides of the river) in farmland to estimate progress. Wetlands are not included in this analysis.
The riverbank length in this catchment is calculated using the River Environment Classification (REC). Farmland use is calculated from the LUCAS System. These databases provide a nationally consistent way to estimate the length of riverbanks that run through farmland*. Catchment journey statistics provided by Healthy Waterways.
*In some areas, the length of recorded fenced waterways may be longer than the calculated riverbank length. The REC makes simplifications and uses algorithms to map waterways, which will not be as precise as local data captured on a property by property basis. Therefore, it can underestimate the length of streams in a catchment, however its strength is that it provides a nationally consistent measure that can be used to compare across catchments.

Construction and Restoration yearly progress comparison
Showing:What is this showing me?
This graph shows the total area (hectares) of wetlands that have been constructed or enhanced/restored. The graph shows cumulative totals over time. The data reported on wetland actions in this catchment are recorded on the Healthy Waterways register.
Enhancements/under restoration
Wetlands under management with recorded actions
What is this showing me?
This graph shows the length (in kilometres) of wetland perimeter in this catchment that have been fenced off, or planted out each year. The lines show the cumulative total length of wetland perimeters that have been fenced off from stock or planted over time. Other actions such as weed control is not included here as it is problematic to track this over time. The data reported on wetland actions in this catchment are recorded on the Healthy Waterways register.

Legal protection of wetlands yearly progress comparison
What is this showing me?
This graph shows the area (in hectares) of wetlands in this catchment that have been assigned legal protection over time. The bars show the cumulative total area of wetlands under legal protection each year. These data are sourced from the QEII National Trust and provided by Healthy Waterways.

The science -
Is it making a difference?
The health of our waterways depends on the local geography and the way we use our land. Long-term monitoring of our waterways is undertaken for a range of indicators so we can understand the health of our water ecosystems and how they are changing over time. Here you can explore the results from long-term monitoring programmes by regional councils, unitary authorities and others.
