Riparian planting effort over time
Showing:–What is this showing me?
This graph shows the riparian planting effort recorded on the Healthy Waterways register. The quantitative measures are the length of waterway banks planted in this catchment and the number of plants over time. You can view progress by selecting either the bank length in kilometres or the number of plants planted (where data are available). The bars show the cumulative totals of recorded riparian planting each year.
We often lack historical data on actions, so the graphs represent efforts since 1999. For some indicators, the regional council or unitary authority has provided initial data based on surveys of how much of the catchment had riparian planting or natural riparian areas 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
65%
of waterways, or 7,051 km of riverbank length has a land use of farmland or urban land – a land use where riparian planting is an appropriate action.
7,051kilometresis the length used to size the Catchment Journey aboveHow 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 riparian planting, the calculation excludes waterways in indigenous or exotic forest, and focuses instead on stock exclusion in farm and urban land. Therefore the length of recorded riparian planting is compared against the total riverbank length (includes both sides of the river) running through farm or urban land to estimate the catchment journey. Riparian planting around wetlands is not included here.
The riverbank length in this catchment is calculated using the River Environment Classification (REC). Farm and urban land 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.

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.
