[2] Blue Mountains ash occurs from Mittagong in the Southern Highlands north to Binna Burra and Springbrook in far south-eastern Queensland.

[3] In the Blue Mountains, it is found on steep slopes and ridges, on southern or eastern aspects, from elevations of 600 to 1,200 metres (2,000 to 3,900 ft) and annual rainfall of 900 to 1,400 millimetres (35 to 55 in).

[3] Eucalyptus oreades is unusual for a eucalypt in that it lacks a lignotuber and therefore is sensitive to bushfire, and often succumbs, with recruitment coming from the seeds stored in the canopy seedbank.

[3] Mature trees over 20 years of age do have a skirt of thicker corky bark which helps them resist low-intensity fires.

[9] Very fast growing in cultivation, Eucalyptus oreades is grown in plantations for timber, both in Australia and overseas in New Zealand and South Africa.
