Acacia saligna (13% of 2008 plantings)

Thesis title: Acacia saligna – laying the foundation for its domestication as a perennial forage

Research image

Thesis summary

I am studying the plant Acacia saligna, which is also known as Koojong or Golden Wattle. Koojong is native to south western Australia but it is grown in several countries around the world where it is used chiefly for livestock feed. It is considered to have good potential as a perennial forage crop in south western Australia and since it is a perennial it is hoped it will help to increase the sustainability of our agricultural systems, notably by helping to manage dryland salinity.

There are two major obstacles to using Acacia saligna as a crop, firstly it is highly variable, so farmers don’t know what will come up from the seed they plant, and secondly its fodder quality is quite poor, which is a big problem if we want to feed it to sheep. The objective of my work is to gather information needed to overcome these problems and domesticate Acacia saligna as a perennial crop plant.

Why my research is important

The primary focus of my work is to help in the fight against dryland salinity. Dryland salinity is a major environmental problem threatening millions of hectares of land in southern and eastern Australia. It is caused when deep-rooted perennial native vegetation is cleared and replaced by shallow rooted annual crops. There are many ways of dealing with the problem, one of which involves planting trees on farmland, unfortunately so much land needs to be revegetated farmers will go out of business unless the trees they plant can also make money. Most of the land affected by dryland salinity is too dry to grow trees for timber, which is why there is a strong push to develop a number of new tree crops like Koojong.

Funding

My project is being funded by the Cooperative Research Center for the Plant-based Management of Dryland Salinity, and the School of Plant Biology at The University of Western Australia.

Acacia pulchella
(13% of 2008 plantings)

From Wikipedia:

Acacia pulchella, commonly known as prickly moses, is a shrub in the family Fabaceae.
Endemic to Western Australia, it is one of the most common shrubs of the bushland around Perth
and in the Darling Range.

Prickly moses is one of only a small number of Acacia species to have true leaves,
rather than phyllodes. It has feathery, bipinnate leaves with leaflets up to 5 mm long.
At the base of each leaf is one or two spines. The flower heads are bright yellow and spherical,
with a diameter of up to 1 cm. It flowers in late winter and early spring.

The name "prickly moses" is said to be a corruption of "prickly mimosa".

Recent research suggests that A. pulchella may in some circumstances suppress
the plant pathogen Phytophthora cinnamomi.[1]

There are four recognised varieties:

Melaleuca lateritia (11% of 2008 plantings)


photo

Melaleuca lateritia, commonly known as the Robin Red-breast Bush, is one of many beautiful Melaleuca species native to the south-west province of Western Australia. It is an erect shrub and although rarely exceeding 1.5 m high by 1 m in diameter in Canberra, often reaches over 2 m in damp situations in the south-west. Its habit is usually open and without pruning it may become untidy and woody at the base. With regular tip pruning, a more compact shrub is obtained.

distribution mapLeaves are light green, about 2 cm long, more or less linear and taper to a fine point. The orange-red, bottlebrush flower spikes grow up to 9 cm long and 5 cm in diameter. They are usually borne on the older wood on small lateral growths. Sometimes flowers are seen close to the ground on very old bushes.

The main flowering period is summer, but some blooms are seen through to autumn and early winter when frost often destroys developing buds. Frost, however, is not an extreme problem as the shrub's vigour is not affected.

Seed is set prolifically on most bushes and the woody capsules persist on the shrub for many years. These may be removed if they look untidy or to improve vigour if the shrub is sparse. By storing the older capsules in a paper bag in a warm place, seeds are quickly released and provide a ready means of propagation. The shrub is also propagated readily from cuttings, using half-hardened wood.

In cultivation, a reasonably well-drained soil and full sun are preferred but M. lateritia will survive and give good flowering in most situations. Ample moisture and regular application of a general fertilizer together with an effective mulch provide the ingredients for good cultivation. The flowers are often visited by honeyeaters, particularly the Eastern Spinebill and New Holland Honeyeaters in Canberra.

M. lateritia should be grown in a prominent position because of its long flowering period at a time when flowers are scarce in the native garden. It appears to be relatively free of pests and diseases.

Name meaning: Melaleuca lateritia
Melaleuca - from two Greek words, melas, black, and leukos, white, because the first Melaleuca described had white branches against a black trunk, possibly blackened by fire (another opinion contrasts the white bark with the very dark foliage of some species);
lateritia - from the Latin meaning brick red, referring to the flowers.

Distribution: South west of Western Australia often in swampy and seasonally wet depressions.
Common Name: No generally accepted common name.
Derivation of Name: Melaleuca...from Greek melas; black and leukos; white, referring to black marks on the white trunks of some species due to fire.
teretifolia... From Latin teres, rounded and folius, a leaf, referring to the leaves of this species which are round in cross section.
Conservation Status: Not considered to be at risk in the wild at the species level.

General Description:

Melaleuca teretifolia 'Georgiana Molloy'   
Melaleuca teretifolia 'Georgiana Molloy'

  

Melaleuca teretifolia is a small to medium shrub from 1 to 3 metres high, usually erect in habit. The linear leaves are rounded in cross section (terete), 40-60 mm long and tapering to a sharp point. The flowers occur in globular-shaped clusters about 20 mm in diameter. The clusters are usually borne on the older branches and resemble the flowering habit of some Hakea species. The flowers are usually white but pink and mauve forms are known. The cultivar 'Georgiana Molloy' (purple-pink flowers) is now regarded as a form of M.teretifolia (previously it was thought to be a hybrid with M.teretifolia as one parent).

M.teretifolia is not widely cultivated although it appears to be hardy in a range of climates and soils. It is one of the hardier Western Australian species in humid areas of the east coast where western species can be difficult to establish. It prefers a sunny position and plants are tolerant of at least moderate frost. The plants can be reluctant to flower under dry conditions.

Propagation is easy from both seed and cuttings. Particular forms, such as 'Georgiana Molloy', must be propagated from cuttings to ensure that plants true to the parent are obtained.

Viminaria juncea (4% of 2008 plantings)

Native Broom is a unique species, being the only Viminaria known, and it grows wild only in Australia.  It occurs in moist temperate parts of most States; not in Northern Territory nor
in areas as dry as the Australian Capital Territory. In swamps
it can be extensive, a tall loose shrub where crowded.

distribution map It can be kept as a shrub amenable to
trimming, but is most distinctive kept to
a single trunk when it reaches 6 m high.
As a small tree it is upright and the slender trunk has a dark fibrous bark. It contrasts with the crown of soft green tints, a waving mass
of slender branches which are bright grassy green while young. They are long, in sprays, very smooth, extremely pliant and
stands up well to storms.

As a shrub it resembles the introduced Broom (hence the common name), with smaller flowers,
but is highly superior. It is brighter in appearance and unlike Broom will grow again after setbacks;
thus it is long-lived.

Ordinary leaves are absent, except in seedlings and occasionally on young stems, and the tree is
generally thought of as leafless. The leaves are in fact minute scales and the mass of growth consists
of phyllodes, as in some Acacias.

In Viminaria juncea the phyllodes are 25 mm long, stringy, smooth and flexible, a fresh green and
always appear healthy. Very rapid, clean growth in almost any soil is one great advantage of the
species which can be put to any garden use in sun or shade. It is tough enough for planting in public
gardens and quite hardy to frost in Canberra.

In November the branches become thickly lined with small, lemon-yellow* pea flowers 1 cm long,
with a light clover-scent detectable from a large mass of plants. The season can last till mid Dec
if cool and moist.

Seed sets in plenty, one small bean per pod, and this is an easy means of propagation.
This species is usually obtainable from native plant nurseries. Autumn would be the best season
to put out new plants in climates such as Canberra's.

Marri (2% of 2008 plantings)

July 2003 article from the WA Forest Alliance
and while the article is some years old, most points are still valid.

The case against recommencing the woodchipping of marri

Tree1


The Forest Products Commission, with the support of its Minister, Hon. Kim Chance MLC, is trying to recommence the woodchipping of marri for export. The FPC is seeking buyers in China, Indonesia, Thailand and Japan and in the meantime is selling job lots on the spot market (e.g.17,000 tonnes to Italy).

Wood chip1. There are many reasons why the Gallop Government should not recommence the woodchipping of marri for export. First, we believe that this would breach the Government’s “Protecting our old growth forests” policy, which has wide community support and helped the ALP win the 2001 State election. The specific provisions in the policy we say would be breached are the commitments to:

  1. incorporate Ecologically Sustainable Forest Management (ESFM) into all logging operations (pp.11, 12);
  2. restructure the native forest logging industry towards sustainability and value adding (pp.7-10);
  3. boost the plantation sector (pp.13-14); and
  4. ensure that royalties reflect the true value of native timber (p. 11).

a. Marri is a magnificent forest tree found only in the south-west of Western Australia. Scientists have shown that marri is probably the most important tree in our forests for birds and mammals. Marri trees produce large amounts of blossom and nectar, and mature trees often have the very large hollows that are nesting sites for endangered species such as black cockatoos, western ringtail possums and owls.

When jarrah/marri forest is clearfelled in gaps, only a small number of ‘habitat’ trees is retained per hectare (three, later four, perhaps now six), and they don’t have to contain hollows. So retained ‘habitat’ trees cannot meet the needs of all 26 species of birds and mammals that must have hollows in standing trees to survive. Besides having very specific requirements as to a hollow’s location, size, shape and entry, these species compete not only between and within species but also with feral European bees. Furthermore, it is unlikely that habitat trees will survive for the centuries required for suitable hollows to develop in the regrowth.

When in the past jarrah/marri forest was selectively logged, the marri trees were usually left standing and so they are the last remnants of the original forest. To fell them now would remove essential habitat for the largest birds and mammals, make the forest even more immature and further degrade its natural structure. This is not ecologically sustainable forest management.

In jarrah/marri forest, the purported threat of marri dominating the regrowth is used as a pretext to fell the marri. However, there is no proof that in the long term (1000 years, which is the physiological age of jarrah) marri if retained would overrun the jarrah. Curiously, in mixed jarrah/marri forest where there are as few as two or three mature karri trees per hectare, DCLM has had no compunction about trying to shift the balance of species in favour of karri by clearfelling such forest and planting it with karri seedlings, an experiment that is unlikely to succeed.

Further, the methods of logging jarrah/marri forest that involve the removal of marri (gap clearfelling and shelterwood) are used largely for economic reasons: they offer the cheapest way to fell and extract the maximum volume of logs. Because these intensive logging methods would eventually leave large expanses of forest as very immature regrowth, they are not ecologically sustainable.

 

Woodchip2b. Native forest woodchipping began in 1975, with the first exports in 1976. Since then, 9.5 million cubic metres (12 million tonnes) of marri chiplogs, almost all from old growth trees, have been sold, initially to WA Chip & Pulp Co Pty Ltd and, since 2000, to Marubeni Corporation of Japan. Karri/marri woodchips were 7th of the eight grades of hardwood woodchips bought by Japanese pulp mills. Of the two species, karri and marri, karri is better for paper production, which means marri is very low grade indeed. For this reason Marubeni stopped buying marri woodchips in November 2001, when plantation-grown bluegum woodchips, which are high quality, began to come on stream. Seeking to once again find markets for this low quality product is not in line with the Gallop Government’s policy of restructuring the timber industry towards sustainability and value adding.

The recent recognition of marri as an excellent furniture timber is ironic after 12 million tonnes of marri logs (including 2 million tonnes of logs of sawlog quality) have been turned into woodchips by the logging industry and forestry agencies, which dubbed marri a “weed tree”! Given the natural properties of marri, only one or two logs in ten are considered suitable as sawlogs. Such a low proportion of useable product would not be tolerated in another industry. In our opinion, if a tree can’t be used for a high value product, it should not be cut done. Since even with current technology it is not possible to judge the timber quality of, they should be left standing for all the ecological benefits they provide. This is essential if ecologically sustainable forest management is to be achieved.

c. Western Australian is exporting plantation-grown bluegum woodchips in increasing quantities. They are high quality woodchips and command top prices. The exporters will surely not be pleased to have the FPC dumping low grade marri woodchips at heavily discounted prices marri trees on the market in competition with their product. Therefore recommencing woodchipping marri for export is contrary to, and directly undermines, the Gallop Government’s commitment to boost the plantation industry.

d. It appears that the FPC, supported by the Minister for Forestry, Hon. Kim Chance MLC, is offering marri woodchips to overseas buyers at such a low price that they are finding it difficult to refuse. This runs counter to the Government’s commitment to ensure that royalties reflect the true value of native timber. As pointed out above, marri has values in forest ecosystems that are beyond price. [It is to be noted that the “immediate review of current royalties for native timber” promised in the ALP’s forest policy hasn’t even begun and that after two years in office, the Gallop Government continues to sell our native timbers for bargain basement prices.]

Woodchip32. There has been no consultation with the community about the proposal to recommence marri woodchipping or to extend the Marubeni (WA Plantation Resources) chiplog sales contract, which is due to expire at the end of this year. Opinion surveys have always shown that Western Australians don’t like their native forest trees to be woodchipped. It is seen as the unnecessary destruction of a much-valued component of our natural environment for a very base, low-value, low-priced product. It is therefore not surprising that the negotiations to recommence sales of marri woodchips involving the FPC and certain foreign companies have been kept secret and have only come to light as a result of our questioning of government activities. Such lack of openness and transparency is unworthy of the Gallop Government and contrary to its professed standards.

3. Many people are putting a great deal of time and effort into helping develop the new Forest Management Plan. To enter into new contracts or even negotiations (especially for such a generally disliked low-value product as woodchips) while this process is still under way shows contempt for both the process and the people involved.

For these reasons there should be no further attempts to ever again produce or export marri woodchips.

What you can do:
Contact the Premier, 197 St George’s Terrace, Perth 6000, phone 9222 9888,
email wa-government@dpc.wa.gov.au and ask him to stop any further attempts to recommence woodchipping marri.

Casuarina obesa (4% of 2008 plantings)


SWAMP SHEOAK FEASIBILITY STUDY

  • Casuarina obesa is a species native to South Western Australia and is widely planted for revegetation purposes on semi saline waterlogged land.

    The tree grows in semi arid areas with a minimum rainfall of 125 mm (50 percentile is 250-500mm) (Doran and Hall, 1983) and a cool to warm temperate climate. It is highly frost resistant, grows in soils with a pH of 6.0 - 8.5, has moderate salt tolerance (growth rates are reduced when salinity reaches 150 - 200 mS/m using an EM38) and occurs in low lying areas that are subject to inundation. The tree grows on a number of soil types ranging from grey clays to a duplex soil over clay. It is also very common in deep sandy duplex and clayey sands, especially depositional areas of waterways and flood planes (O'Sullivan pers. comm. 2002) Its preferred soil type would be a gradational soil eg a clay loam grading into a medium clay (White, 2001).

  • Cultural Characteristics

    • Casuarina obesa is dieback tolerant, it fixes nitrogen and is an outstanding coloniser that suckers freely.
    • It is easily propagated and can be direct seeded.
    • The tree grows rapidly but is very susceptible to grazing damage from stock, rabbits, kangaroos and insects.
    • The biology of Casuarina obesa lends itself to rapid genetic development (Barbour pers comm, 2002)
    • Casuarina obesa grows to a small tree of 14 metres high and with pruning can have a clean bole and be relatively straight (Midgley, 1981 in White, 2001). The trunks of mature trees are commonly heavily fluted and this may reduce the recovery of sawn material (McFall pers. comm. 2002). The same condition is common in other Casuarina species (O'Sullivan pers. comm. 2002).
    • In its natural state the tree tends to grow multi-stemmed and requires regular pruning to produce good timber.
    • Casuarina species have excellent tolerances of a wide array of adverse environmental conditions (Midgley, 1981 in White, 2001)
      (It is also accepted to be resistant to bush fire.)
