One of the Eucalyptus Ash Group, Mountain Ash is the mighty tree of Australia. It is the world's tallest flowering plant with some specimens being recorded at well over 100 metres tall. The Sequoia species, the Redwood of north America, is the tallest living tree in the world but is a non-flowering plant.

Mountain Ash is a dominant species of the wet sclerophyll forests of Victoria and Tasmania. Wet sclerophyll forests are not often subjected to bushfires, but when they do occur they are both devastating and beneficial. They are devastating for the deaths of humans and animals, the damage to property and the visual effects they leave behind. They are beneficial for the forest itself. The seed produced by the Mountain Ash tree does not remain viable for very long when it falls to the ground. Under normal forest conditions once it has reached the ground it is often eaten by ants and also has to penetrate the forest litter to reach the earth. If the seed manages to produce roots it then finds that there is not enough light to develop properly, consequently there is very little regeneration. Once in a while a hot, fierce fire comes along, clears the forest floor, destroys the canopy and opens the seed capsules. The capsules produce millions of seeds per hectare which fall into nutrient rich ash from which a seedling rapidly develops. This is why stands of Mountain Ash of uniform age are often observed.
