In a collaboration with Tom Levick from the CSRIO, a mapping exercise identified that Willoughby Council’s largest ecosystem health problem is most affected by dieback.  Dieback refers to the gradual deterioration of health in trees, which is usually caused by a combination of factors, such as disease and pathogens, insect attack and/or stressful climate conditions. This map shows the distribution of Phytophthora in Willoughby Council and below it are download links to information on preventing it, as well as proposed exhibition elements for the Willoughby Council Tree Festival that came about to raise support for the natural environment, because of the serious vandalism involving the illegal cutting and poisoning of 265 trees in 2023.
