E. regnans is confined to Tasmania and Victoria. It is one of the three or four most important timber species in these two states. In 1958, E. regnans produced the fifth largest volume of sawn eucalypt timber in Australia (Hanson, 1961). E. regnans grows best under fairly cool conditions at 100 ft. to 2,000 ft. in Tasmania and at 600 ft. to 4,000 ft. in Victoria, on a variety of soils of medium to high fertility under a fairly evenlly distributed rainfall of at least 45 inches per year. The tree frequently exceeds 200 ft. in height (up to 322 1 ) and usually grows in pure stands of one age, sometimes with 10,000 cubic feet of merchantable wood per acre. Its most common associates are E. delegatensis and E. oblique,. E. Regnans is "spar aged" at 150 years and "mature" at 250 years. It rarely exceeds 400 years. In dense stands on good sites it may grow an average of 100 cubic feet of merchantable timber per acre per year during the first 100 years. Its intended rotation is 60 to 90 years.
