A tree change DSC_0104

One cannot help but feel humble in the presence of these ancient River Red Gums. They have lived through many changes, on a seasonal basis (actually required for life), the changes of time (evolutionary) and then the man-made changes we have imposed on them.


Recent studies by ANU found that the species is under serious threat by rising CO2 levels and their survival may depend on curbing carbon emissions. Increased CO2 levels caused the trees to reduce the amount of essential oils produced and stored in their leaves. These essential oils are vital to defend the trees from insect and mammal herbivores, including koalas, eating them.
