Observations of Eucalypt Decline in Temperate Australian Forests and Woodlands

This is a report of a brief study tour of forest and rural tree decline in south-western
Australia, Tasmania and south-eastern Australia. There were many similarities
amongst the different cases examined, even though a wide range of pests, pathogens
and parasites were associated with them. Unfavourable climatic conditions, especially
drought, were associated with many cases, however decline typically occurred low in
the landscape on sheltered or water-accumulating sites. Acute drought stress was
apparent on some more exposed sites. There were often contrasts in the health of the
same tree species in the same climatic conditions under different management,
especially different fire and grazing regimes.
