Mallee (habit)

Source: Wikipedia, the free encyclopedia.

Typical form of a mallee, Eucalyptus stricta

Mallee are trees or shrubs, mainly certain species of

Victoria, and has given rise to other uses of the term, including the ecosystems
where such trees predominate, specific geographic areas within some of the states and as part of various species' names.

Etymology

Look up mallee in Wiktionary, the free dictionary.

The word is thought to originate from the word mali, meaning water, in the

Woiwurrung language and other Aboriginal languages of Victoria, South Australia, and southern New South Wales.[3]

Overview

The term mallee is used describe various species of

bulbous woody structure called a lignotuber, or mallee root,[4] usually to a height of no more than 10 m (33 ft). The term is widely used for trees with this across southern Australia,[5] across the states of Western Australia, South Australia, New South Wales and Victoria.[1] The term is also applied to other eucalypts with a similar growth habit,[2] in particular those in the closely related genera Corymbia and Angophora
.

Some of the species grow as single-stemmed trees initially, but recover in mallee form if burnt to the ground by bushfire.[6]

Over 50 per cent of eucalypt species are mallees, and they are mostly slow-growing and tough. The lignotuber enables the plant to regenerate after fire, wind damage or other type of trauma.[4]

Range

Mallees are the dominant vegetation throughout

semi-arid areas of Australia with reliable winter rainfall. Within this area, they form extensive woodlands and shrublands covering over 250,000 km2 (97,000 sq mi) in New South Wales, north-western Victoria, southern South Australia and southern Western Australia, with the greatest extent being in South Australia (118,531 square kilometres (45,765 sq mi)).[6]

There are also some species found in the

Eucalyptus setosa.[6]

Farming on mallee land

Scrub/mallee roller being used in South Australian mallee, c.1922

legislation which encouraged closer settlement made it even tougher for farmers to make a living.[7]

Grubbing the mallee lands was a laborious and expensive task estimated at £2–7 per acre,

scrub or mallee roller was invented, which flattened the stumps and other vegetation, after which it would all be burnt and crops sown.[10] The technique became known as "mullenising", as the invention of the device was attributed to a farmer called Mullen.[11]

A few years later the

ploughshares, enabling the whole plough to move over stumps rather than having to steer around them, and proved a great success.[12][13]

Uses of the term

Further information: Mallee (disambiguation)

The term is applied to both the tree itself and the whole plant community in which it predominates,

major vegetation groups.[6]

Several common names of eucalypt species have "mallee" in them, such as the

blue mallee (E. gamophylla and E. polybractea
).

The term is used in the phrase strong as a mallee bull, and is

colloquially used is for any remote or isolated area, or as a synonym for outback.[2]

Species

Widespread mallee species include:[6]

The following four Western Australian species can be found in the Waite Arboretum in Adelaide, and are suitable for gardens:[4]
