The objective of this study was to determine the area, severity and location of secondary saline discharge in the Dundas Tablelands East and West LMU's and present it in map and database form.
Aerial photos were used for the location of saline sites and an extensive ground truthing program carried out using ISCON techniques for the classification of salt severity.
A total of 8281 hectares was found to be salt affected with sites varying in size from 146.15 to 0.01 hectares. The majority of sites were affected by a low level of salinity, although some were moderately or severely saline. Most of the discharge sites appeared in drainage lines and depressions, with some in gullies, slopes, break of slopes or lake margins.
The majority of sites had not been treated. This highlights the need to continue to develop an awareness of salinity in the area and provide funding to assist with treatment of saline areas.
