Timber Species: Forest Reds

Description of Species:

More of a “category” of timber than sourced from any particular type of tree, forest reds are nevertheless most often sourced from red river gum trees, a eucalyptus varietal that’s highly prized for its durability and, yes, its lush red colour. A plantation species that originates in wide dispersal in Australia, most red river gums used in forest reds can be found populating the banks of inland watercourses.

With a maximum height of around 45 meters tall and smooth, variegated bark that sheds in ribbons, red river gums have dense and thick canopies that provide some much-needed shade in the heat of a central Australia day. These red eucalyptus trees also play a role in strengthening the soil near watercourses, fending off erosion and solidifying riverbanks, though they do have a tendency to self-prune by dropping limbs quite often, resulting in a nickname of “widowmaker” trees for landing on unsuspecting individuals!

As a timber, red river gums contribute strength and stability to forest red mixes, making for not just attractive flooring but as resilient construction materials for fencing and veneers, for the production of charcoal, and even for the building of railway sleeper cars. Its 3.7 pH leaves it moderately acidic, while its 9.0 average Janka rating provides some much-needed hardness and rigidity alongside its 900 kg/m³ dry density.

Age and weathering can provide dramatic shades for forest reds, with hues and tones ranging as far afield as light pink, brilliant red, or even nearly pitch or charcoal black. Particularly luxurious and warm, forest reds made in part from red river gums are perennially popular, bringing an earthy, friendly tone to any floor whether it’s solid timber, parquetry, or even decking, and the comparison between natural variation in lighter and darker hues make for dramatic flooring choices for entryways and entertainment spaces within the home.

Dry Density:  900 kg/m³

Janka Hardness: 9 kN

These properties are only a guide, as timber is a natural product there will be variations within any species. The Janka Dry Hardness rating measures the hardness of the wood. The higher the number the harder the wood.
