Phytophthora multivora is a species of Oomycete, water moulds, identified as a plant pathogen implicated in dieback. [1] It was first isolated in tuart forest of Southwest Australia in a study of the decline of tuart Eucalyptus gomphocephala , jarrah Eucalyptus marginata , peppermint Agonis and banksia species. [2]

The species was found to occur in dead and dying woody species, Eucalyptus gomphocephala, E. marginata, Agonis flexuosa , banksias B. menziesii and B. grandis and at the fine roots of E. marginata and Banksia littoralis . The study area included samples at Yalgorup, Jarrahdale, Wanneroo, Walpole and Pemberton in Western Australia. [2]

The epithet of the species is in reference to the wide range of flora it infects. [1]

<i>Banksia</i> Genus of flowering plants in the family Proteaceae

Banksia is a genus of around 170 species of flowering plants in the family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes, and woody fruiting "cones" and heads. Banksias range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.

<i>Eucalyptus marginata</i> Species of plant endemic to Western Australia

Eucalyptus marginata, commonly known as jarrah, djarraly in Noongar language and historically as Swan River mahogany, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a tree with rough, fibrous bark, leaves with a distinct midvein, white flowers and relatively large, more or less spherical fruit. Its hard, dense timber is insect resistant although the tree is susceptible to dieback. The timber has been utilised for cabinet-making, flooring and railway sleepers.

<i>Phytophthora</i> Genus of single-celled organisms

Phytophthora is a genus of plant-damaging oomycetes, whose member species are capable of causing enormous economic losses on crops worldwide, as well as environmental damage in natural ecosystems. The cell wall of Phytophthora is made up of cellulose. The genus was first described by Heinrich Anton de Bary in 1875. Approximately 210 species have been described, although 100–500 undiscovered Phytophthora species are estimated to exist.

<i>Corymbia calophylla</i> Tree found in Western Australia

Corymbia calophylla, commonly known as marri, is a species of flowering plant in the family Myrtaceae and is endemic to the southwest of Western Australia. It is a tree or mallee with rough bark on part or all of the trunk, lance-shaped adult leaves, branched clusters of cup-shaped or pear-shaped flower buds, each branch with three or seven buds, white to pink flowers, and relatively large oval to urn-shaped fruit, colloquially known as honky nuts. Marri wood has had many uses, both for Aboriginal people, and in the construction industry.

<i>Banksia brownii</i> Species of shrub in the family Proteaceae found in Australia

Banksia brownii, commonly known as feather-leaved banksia or Brown's banksia, is a species of shrub that grows in southwest Western Australia. A plant with fine feathery leaves and large red-brown flower spikes, it usually grows as an upright bush around two metres (6.6 ft) high, but can also occur as a small tree or a low spreading shrub. First collected in 1829 and published the following year, it is placed in Banksiasubgenus Banksia, section Oncostylis, series Spicigerae. There are two genetically distinct forms.

<i>Eucalyptus jacksonii</i> Species of eucalyptus

Eucalyptus jacksonii, commonly known as the red tingle, is a species of tall tree endemic to the southwest of Western Australia and is one of the tallest trees found in the state. It has thick, rough, stringy reddish bark from the base of the trunk to the thinnest branches, egg-shaped to lance-shaped adult leaves, flower buds in groups of seven, white flowers and shortened spherical to barrel-shaped fruit.

<i>Banksia marginata</i> Tree or woody shrub in the family Proteaceae found throughout much of southeastern Australia

Banksia marginata, commonly known as the silver banksia, is a species of tree or woody shrub in the plant genus Banksia found throughout much of southeastern Australia. It ranges from the Eyre Peninsula in South Australia to north of Armidale, New South Wales, and across Tasmania and the islands of Bass Strait. It grows in various habitats, including Eucalyptus forest, scrub, heathland and moorland. Banksia marginata varies widely in habit, ranging from a 20-centimetre (7.9 in) shrub to a 12-metre (40 ft) tree. The narrow leaves are linear and the yellow inflorescences occur from late summer to early winter. The flower spikes fade to brown and then grey and develop woody follicles bearing the winged seeds. Originally described by Antonio José Cavanilles in 1800, further collections of B. marginata were designated as several separate species by Robert Brown in 1810. However, all were reclassified as a single species by George Bentham in 1870. No distinct subspecies have been recognised by Banksia expert Alex George, who nonetheless concedes that further work is needed.

<i>Banksia sphaerocarpa</i> Shrub or tree in the family Proteaceae widely distributed across the southwest of Western Australia

Banksia sphaerocarpa, commonly known as the fox banksia or round-fruit banksia, is a species of shrub or tree in the plant genus Banksia. It is generally encountered as a 1–2 m (3.3–6.6 ft) high shrub, and is usually smaller in the north of its range. This species has narrow green leaves, and brownish, orange or yellow round flower spikes which may be seen from January to July. It is widely distributed across the southwest of Western Australia, growing exclusively in sandy soils. It is usually the dominant plant in scrubland or low woodland. It is pollinated by, and is a food source for, birds, mammals, and insects.

<i>Banksia verticillata</i> Shrub of southwest Western Australia

Banksia verticillata, commonly known as granite banksia or Albany banksia, is a species of shrub or (rarely) tree of the genus Banksia in the family Proteaceae. It is native to the southwest of Western Australia and can reach up to 3 m (10 ft) in height. It can grow taller to 5 m (16 ft) in sheltered areas, and much smaller in more exposed areas. This species has elliptic green leaves and large, bright golden yellow inflorescences or flower spikes, appearing in summer and autumn. The New Holland honeyeater is the most prominent pollinator, although several other species of honeyeater, as well as bees, visit the flower spikes.

The ecology of Banksia is the relationships and interactions among the plant genus Banksia and its environment. Banksia has a number of adaptations that have so far enabled the genus to survive despite dry, nutrient-poor soil, low rates of seed set, high rates of seed predation and low rates of seedling survival. These adaptations include proteoid roots and lignotubers; specialised floral structures that attract nectariferous animals and ensure effective pollen transfer; and the release of seed in response to bushfire.

<i>Eucalyptus patens</i> Species of eucalyptus endemic to Western Australia

Eucalyptus patens, commonly known as yarri or blackbutt, is a species of flowering plant in the family Myrtaceae and is endemic to the south-west of Western Australia. It has rough bark on the trunk and branches, lance-shaped leaves, creamy-white flowers and spherical to oval fruit.

Jarrah Forest, also known as the Southwest Australia woodlands, is an interim Australian bioregion and ecoregion located in the south west of Western Australia. The name of the bioregion refers to the region's dominant plant community, jarrah forest – a tall, open forest in which the dominant overstory tree is jarrah.

The western false pipistrelle, species Falsistrellus mackenziei, is a vespertilionid bat that occurs in Southwest Australia. The population is declining due to loss of its habitat, old growth in tall eucalypt forest which has largely been clear felled for tree plantations, wheat cultivation and urbanisation. Although it is one of the largest Australian bats of the family, the species was not recorded or described until the early 1960s. A darkly colored bat with reddish brown fur and prominent ears, they fly rapidly around the upper canopy of trees in pursuit of flying insects.

<span class="mw-page-title-main">Tuart forest</span>

Tuart forest is an open forest in which the dominant overstorey tree is Eucalyptus gomphocephala (tuart). This form of vegetation occurs only in the Southwest Botanical Province of Western Australia. Tuart being predominantly a coastal tree, tuart forest occurs only in a narrow belt along the coast.
