Treeplanting in a healthy catchment

|Planting trees and other deep-rooted perennial plants is an important activity for managing salinity. Trees can reduce recharge to groundwater, but can also reduce valuable catchment runoff to streams and rivers. The maps in the poster below show how areas can be identified as priority areas for tree planting to reduce salinity in the upper Loddon catchment. High priority areas for tree planting are those contributing to high stream salinity. Low priority areas are those contributing to low stream salinity. The individual maps in the poster below are also provided separately on this page.|
The poster is based on products coming out of the Victorian REALM Tributary modelling work, including the spatial representation of salt and water runoff rates for the baseline/benchmark period. On top of this data is overlaid a simplified dryland Rapid Assessment Tool – that reduces salt and water from each subcatchment (by 50% in this example), looks at downstream changes in river salinity and then makes comments on priorities for planting trees and other deep-rooted perennial plants.
