- Mountain ash is also the common name of Fraxinus texensis, a tree in Texas.

Unusually for a Eucalypt, it cannot usuallly recover by re-shooting after fire, and can only regenerate from seed. In the long term occasional fires (such as the naturally ignited blazes thought to occur about every 200 years on average) do not severely impact Mountain Ash forest but, because it takes roughly twenty years for seedlings to reach sexual maturity, repeated fires in the same area can wipe stands out.
Mountain Ash is valued for its timber: not so much because of any particular virtue of the timber itself -- it is a heavy, fine-grained eucalyptus hardwood much like several others -- but because of the sheer volume that can be harvested. Primary uses are sawlogging and woodchipping. Very few natural stands of Mountain Ash remain, but substantial areas of regrowth exist, and it is sometimes grown in plantations.
Great controversy surrounds its use: as the largest eucalypt of all it has symbolic value to conservationists, it provides essential habitat to important birds and mammals (notably the Lyrebird and the endangered Victorian state animal emblem Leadbeater's Possum), and in a land of vast, barren plains, the contrasting lush fertility of Mountain Ash forest is particularly dear to nature lovers. Although the status of E. regnans as a species is secure, political opposition to logging it has grown very strong in recent years (particularly in the case of woodchipping), and the extent of future harvesting remains uncertain.
Mountain Ash regrowth in the Otway Ranges, southern Victoria. If not logged again, these trees will more than double in size as they mature.
