Jocks Lagoon
Jocks Lagoon is an freshwater coastal lagoon in north-eastern Tasmania, Australia. In 1982 it was designated a wetland of international importance under the Ramsar Convention. Description The lagoon is located approximately south-east of the town of St Helens. It lies partly on private land and partly at the southern end of the St Helens Point conservation area. One of a chain of wetlands along St Helens Point, it is inland from the coast, near a dunefield. About long and wide, it is dystrophic, with tannin-stained, low-nutrient, acidic waters. Water levels fluctuate with rainfall and reach a depth of . Vegetation While the northern half of the lagoon is mainly open water, the southern half is mostly covered with emergent rushes and sedges. Threatened plants recorded from the site, or suspected to be present, include jointed twigsedge, slender twigsedge, zigzag bogsedge, yellow onion orchid and erect marshflower. A total of 51 vascular plant species were recorded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Ramsar Sites In Australia
This is a list of wetlands in Australia that are designated by the Ramsar Convention as sites of international importance. Under the convention, the wetlands are considered as being of significant value not only for the Australian community, but for humanity as a whole. The Ramsar Convention on Wetlands came into force for Australia on . As of 28 February 2018, Australia has 66 sites designated as Wetlands of International Importance, with a total area of . Management of Ramsar wetlands in the Australian jurisdiction The management of Ramsar sites listed within Australia is controlled at national level by the Australian government via the ''Environment Protection and Biodiversity Conservation Act 1999'' and its accompanying regulations, the ''Environment Protection and Biodiversity Conservation Regulations 2000''. The act, as of 2015, lists the principles required for meeting treaty obligations in respect to "wetlands of international importance" including "environmental appr ...

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on (Australia's) Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted for life in swamp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vascular Plant
Vascular plants (), also called tracheophytes () or collectively Tracheophyta (), form a large group of land plants ( accepted known species) that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida ''sensu lato''. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "higher plants", as it was believed that they were further evolved than other plants due to being more complex organisms. However, this is an antiquated remnant of the obsolete scala naturae, and the term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of The Environment (Australia)
The Department of the Environment and Energy (DEE) was an Australian government department in existence between 2016 and 2020. The department was responsible for matters including environment protection and conservation of biodiversity as well as energy policy. It was established in July 2016 by the Turnbull Government after the 2016 federal election. Following the appointment of Scott Morrison as Prime Minister, Josh Frydenberg was elevated to Treasurer of Australia, whereby Frydenberg's previous ministerial positions were separated, with Melissa Price as Minister of the Environment and Angus Taylor as Minister for Energy. Price was reshuffled from her position in 2019, and was replaced by Sussan Ley. By an administrative order issued on 5 December 2019 and effective from 1 February 2020, the environment functions of the department were merged with all functions of the Department of Agriculture, to form the Department of Agriculture, Water and the Environment.

Villarsia Exaltata
''Villarsia'' is a genus of aquatic flowering plants in the family Menyanthaceae. The genus is named for the French botanist Dominique Villars (1745–1814). ''Villarsia'' are wetland plants with basal leaves. The inflorescence is a branched panicle with numerous flowers. Flowers are five-parted, either yellow or white, and the petals are adorned with wings. A number of its Australian species were reassigned to ''Ornduffia''. ''Villarsia'' is largely restricted to Australia, but some species are found in Southeast Asia, and '' V. capensis'' and others exist in South Africa. The geographic distribution of species is given below: South Africa: * '' Villarsia capensis'' (Houtt.)

Microtidium Atratum
''Microtis atrata'', commonly known as the swamp mignonette orchid or yellow onion orchid and sometimes as ''Microtidium atratum'', is a species of orchid endemic to southern Australia. It has a single thin leaf and up to forty or more yellowish-green flowers. The flowers are the smallest of any Australian ground-dwelling orchid. The orchid usually grows in large colonies after fire and although small, are easily seen because of their very large numbers in their blackened surroundings. Description ''Microtis atrata'' is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, smooth, more or less solid leaf, long and about wide. Between two and forty or more yellowish-green flowers are densely crowded along a flowering stem long, reaching to a height of . The plants are sometimes up to tall if growing in water. At about long and wide, the flowers are the smallest of any terrestrial Australian orchid, and as they age, they turn black. The dorsal ...

Baumea Gunnii
''Baumea'' is a genus of the sedge family, which includes around 30 species native to Madagascar and the Pacific Islands, with 15 species in Australia. All are perennial rhizomatous herbs, with leaves and stems very similar in appearance. The inflorescence is terminal, with the flowers tightly clustered or loosely arranged. The fruits are small nuts. It is closely related to the genus '' Machaerina'', and is sometimes included in that genus.

Dystrophic Lake
Dystrophic lakes, also known as humic lakes, are lakes that contain high amounts of humic substances and organic acids. The presence of these substances causes the water to be brown in colour and have a generally low pH of around 4.0-6.0. Due to these acidic conditions, there is little biodiversity able to survive, consisting mostly of algae, phytoplankton, picoplankton, and bacteria.Drzymulska, D., Fiłoc, M., Kupryjanowicz, M., Szeroczyńska, K., & Zieliński, P. 2015.
