Ash, Alpine and Mountain
Eucalyptus delegatensis
Eucalyptus Regnans

Description
ash - map
ash - grain
Alpine and Mountain Ash are both found in Victoria and Tasmania, with Alpine Ash extending into the sub-alpine regions of southern New South Wales and the ACT. They both rank amongst our tallest eucalypts, with Mountain Ash being one of the tallest trees in the world.

In Tasmania the species are commonly mixed with other species such as Messmate and sold as ‘Tasmanian Oak’. The ‘oak’ connection is due to the similarities in appearance with Oak. Both species have a rough bark on the lower portion of the trunk with a smooth whitish bark above which may vary to greenish grey in Mountain Ash. In southern Tasmania the whole trunk of Alpine Ash may be covered with the rough bark.
 

Appearance
The heartwood of Alpine Ash is a pale pink to yellow brown in colour with the sapwood being similar in colour and not easily distinguishable. Both the heartwood and sapwood of Mountain Ash are pale brown in colour. Both species are quite fast growing and often show clearly distinguishable growth rings. The grain is generally straight with occasional waviness and gum vein is a common feature.
 

Properties
The heartwood is of only low durability (Class 4), limiting them to more internal or suitably protected applications. Their sapwood is generally resistant to lyctid borer attack. Both species work well and offer great versatility in its uses. Applications include general framing, flooring, and panelling, joinery and furniture. Definition of properties
