• N
A field sheet to identify and manage waterlogged and saline
catchments in south-west Victoria* Jim Cox, Rob Fitzpatrick, Lee-anne Mintern, John Bourne and Glenn Whipp
• A method developed
using soil landform units
in the Woorndoo Land
Protection Group Area.
• From field assessment of
your soils and landscape,
match them with the soil
sequence in the centre
section of this field sheet.
• Not all soil types will
occur, so check the table
on the back of this sheet
for the most likely
sequence in your area.
• Identify and implement
appropriate management
options (see Cox et al.
1999*).

• Fence off • Perenial pasture • Plant salt tolerant grasses • Exclude stock throughout winter • Stabilise bare eroded areas with salt
tolerant trees, shrubs and native grasses • Add lime to areas that are strongly
sulfidic to prevent acid conditions • Do not drain strongly sulfidic areas
tolerant to salinity and waterlogging
• Plant moderately salt tolerant crops
• Agroforestry • Remove stock in
wet periods
Strongly waterlogged and saline sulfidic Strongly waterlogged, saline and or eroded
Very poorly drained black saline sulfidic soil
Very poorly drained sodic and saline soil
