List of extinct flora of Australia

Last updated

This is a list of recently extinct flora of Australia, that is plants that are considered to have become extinct since the European colonisation of Australia in 1788. Within Australia there are mechanisms for registering an extinction at the federal, state and territory levels. Federal and state listings may vary due to regional extinctions or because of differing definitions of extinction in the various pieces of legislation.

Plants listed as extinct by the federal government

Plants and animals are listed as extinct and the federal level under the auspices of the Environment Protection and Biodiversity Conservation Act 1999. The Act lists all plants considered to have become extinct since the commencement of European settlement of Australia in 1788. There are 37 species currently listed as extinct under the Act. [1]

Of note, the species Pimelea spinescens subsp. pubiflora was presumed extinct after 1901, but a population was discovered in 2005. [2] The orchid Diuris bracteata was also considered extinct after its first collection in 1899, but it was thought to have been rediscovered in 1998. The later collections are now considered to be Diuris platichila . [3] [4] The spiny everlasting ( Acanthocladium dockeri ) was reclassified as critically endangered in 2006 after it was rediscovered in 1999. [5] Bennett's Seaweed, declared extinct under the EPBC Act in 1999; was the first protist listed as extinct by the IUCN in 2004. [6]

The Brisbane Water National Park is a protected national park that is located in the Central Coast region of New South Wales, in eastern Australia. The 11,506-hectare (28,430-acre) national park is situated 47 kilometres (29 mi) north of Sydney, 10 kilometres (6.2 mi) west of Woy Woy, and 12 kilometres (7.5 mi) southwest of Gosford.

<span class="mw-page-title-main">Threatened species</span> IUCN conservation category

Threatened species are any species which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment.

<span class="mw-page-title-main">Conservation status</span> Indication of the chance of a species extinction, regardless of authority used

The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.

Rare or Threatened Australian Plants, usually abbreviated to ROTAP, is a list of rare or threatened Australian plant taxa. Developed and maintained by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the most recent edition lists 5031 taxa. The list uses a binary coding system based on the IUCN Red List categories for "Presumed Extinct", "Endangered", "Vulnerable", "Rare" or "Poorly Known". However, it also provides for additional information such as geographic range and occurrence in protected areas.

The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, Nuytsia, which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered.

Muehlenbeckia horrida subsp. abdita. commonly known as remote thorny lignum, is a critically endangered shrub endemic to Western Australia.

<i>Threatened Species Protection Act 1995</i>

The Threatened Species Protection Act 1995, is an act of the Parliament of Tasmania that provides the statute relating to conservation of flora and fauna. Its long title is An Act to provide for the protection and management of threatened native flora and fauna and to enable and promote the conservation of native flora and fauna. It received the royal assent on 14 November 1995.

Caladenia elegans, commonly known as the elegant spider orchid, is a species of orchid endemic to a small area near the coast of the south-west of Western Australia. It resembles the common spider orchid and often grows with it but its flowers are a different colour and C. elegans usually grows in poorly-drained soils. Only about 2,300 plants remained in 2016.

Caladenia audasii is a plant in the orchid family Orchidaceae and is endemic to Victoria. It is a rare ground orchid with a single hairy leaf and a single yellow flower.

Caladenia brachyscapa is a plant in the orchid family Orchidaceae and is native to Victoria and possibly Clarke Island in Bass Strait. It is a ground orchid with a single hairy leaf and a reddish-pink flower with thick, black, club-like swellings on the petals and sepals. Although formally described in 1988 living specimens have not been observed since 1979.

<i>Caladenia conferta</i> Species of orchid

Caladenia conferta, commonly known as the crowded spider orchid or coast spider-orchid, is a plant in the orchid family Orchidaceae and is endemic to a restricted area in South Australia.

Caladenia pumila, commonly known as the dwarf spider orchid is a plant in the orchid family Orchidaceae and is endemic to Victoria, Australia. It is a ground orchid with a single erect, hairy leaf and a single white flower with pale pink stripes. Its short flowering stem distinguishes it from other Victorian spider orchids. After 1933 it was presumed extinct until two plants were discovered in 2009.

It has a single tubular leaf and up to eighty greenish flowers with purplish markings. Before being rediscovered in 2020, the plant had last been seen in 1933 and was presumed extinct.

<i>Prasophyllum suttonii</i> Species of orchid

Prasophyllum suttonii, commonly known as the mauve leek orchid, Mount Buffalo leek orchid or Buffalo leek-orchid, is a species of orchid endemic to the Australian Alps. Some authorities list the species as being a Victorian endemic now extinct whilst others list is as occurring in New South Wales and extant. Descriptions of the species also differ. It has a single tube-shaped leaf and up to thirty five white flowers with purple or mauve marks.

Diuris bracteata is a species of orchid which is endemic to New South Wales. It has two folded leaves and up to eight yellow flowers with blackish marks. After its collection in a Sydney suburb in 1888, no further collections were made and the species was presumed extinct until 2004 when it was rediscovered near Gosford.
