Yesterday I posted some photographs of healthy Blue Gums in the Grose Valley.
I suggested in the comment thread that followed, that River Red Gums are more suseptible to fire, and that a fire in October 2006 in the Barmah forest destroyed many trees.
River Red Gums are also susceptible to drought.
The following photographs were taken in the Murray Valley last November.

Trees along the Murray River were healthy, but this isolated stand of trees on a farmed section of the floodplain appeared mostly dead – I assume from drought.

Is it possible they were killled off by rising salt as the freshwater underground supplies are used up for irrigation etc during drought periods. I have seen river gums still thriving in drought areas where there is no irrigation taking place?
