Tasmanian Oak

Tasmanian Oak

English Name: Tasmanian Oak

Latin Name: Eucalyptus delegatensis, E. obliqua, E. regnans

Family: Myrtaceae

Genus: Eucalyptus

Brief introduction: Tasmanian Oak is the name used for three almost identical species of eucalypt hardwoods that are normally marketed collectively. E. delegatensis grows at higher altitudes, while E. regnans is found in wetter sites. E. obliqua has a wide distribution, occurring in wet forests but also extending into drier areas. The name Tasmanian Oak was originally used by early European timber workers who believed the eucalypts showed the same strength as English Oak.

Eucalypts are light demanding and grow best where they are not overshadowed. Regeneration occurs after fire, and seedlings establish best on bare mineral soil in the absence of leaf litter. In Tasmania, eucalypts may live for 400 years or more and regularly attain a height of 70m; some individuals have been recorded as reaching 100m. Mature trees may be 3-4m or more in diameter.
