Logan Lagoon
Logan Lagoon is a 2172 ha wetland Conservation Area on Flinders Island, the largest of the Furneaux Group at the eastern end of Bass Strait, which is part of the Australian state of Tasmania. History The lagoon area was declared a wildlife sanctuary in 1968, with additional blocks of adjacent land added subsequently. In 1982 it was designated a wetland of international importance under the Ramsar Convention. In 1996 it was declared a Shorebird Network Site. Description Logan Lagoon is a coastal wetland complex at the south-eastern corner of Flinders Island, lying some 5 km east of the village of Lady Barron. It is isolated from the sea by a large sand bar which is infrequently breached by either high water levels in the lagoon or by rough seas eroding the bar. The water in the lagoon is generally 1–2 m deep and fluctuates with rainfall, occasionally drying out. The 75 km2 catchment of the lagoon is mainly agricultural land.

Ramsar Convention
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over . The countries with most sites are the United Kingdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callitris Rhomboidea
''Callitris rhomboidea'', commonly known as the Oyster Bay pine, Tasmanian cypress pine, Port Jackson pine, Illawarra Mountain pine, or dune cypress pine, is a species of conifer in the family Cupressaceae. It is native to Australia, occurring in South Australia, Queensland, New South Wales, Victoria and Tasmania. It has become naturalized near Auckland, New Zealand and can be found on the island of Taillefer Rocks in Tasmania. Description ''Callitris rhomboidea'' is a spreading evergreen shrub or small tree growing to 15 meters tall. The hairless leaves are keeled dorsally, green or glaucous in colour, and typically measure 2-3 millimeters long, though some may grow to 7 millimeters. This species is monoecious. The female cones A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines conn .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Areas Of Tasmania
Protected areas of Tasmania consist of protected areas located within Tasmania and its immediate onshore waters, including Macquarie Island. It includes areas of crown land (withheld land) managed by Tasmanian Government agencies as well as private reserves. As of 2016, 52% of Tasmania's land area has some form of reservation classification, the majority is managed by the Tasmania Parks & Wildlife Service (about 42% of total Tasmanian land area). Marine protected areas cover about 7.9% of state waters. Within each classification of reserve there may be a variation of IUCN categories Australia is a signatory to the Convention of Biological Diversity and as such has obligations to report the status of its National Reserve System.IUCN provides on its website a prescription for activities consistent with the categorisation system. Changes made to the ''Nature Conservation Act 2002'' in 2014 permit timber harvesting. These changes made in addition to the already established right t ...

Cape Barren Goose
The Cape Barren goose (''Cereopsis novaehollandiae'') is a large goose resident in southern Australia. Etymology The species' common name is derived from Cape Barren Island, where specimens were first sighted by European explorers. It is known in the local Jardwadjali language as ''toolka''. Taxonomy The Cape Barren goose was first described by English ornithologist John Latham in 1801 under the current binomial name. It is a most peculiar goose of uncertain affiliations (Sraml ''et al.'' 1996). It may either belong in the "true geese" and swan subfamily Anserinae or in the shelduck subfamily Tadorninae as distinct tribe Cereopsini, or be separated, possibly including the prehistorically extinct flightless New Zealand geese of the genus ''Cnemiornis'', in a distinct subfamily Cereopsinae. The first bones of the New Zealand birds to be discovered were similar enough to those of the Cape Barren goose to erroneously refer to them as "New Zealand Cape Barren goose" (''"Cereopsis" n ...

Waterfowl
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins the galliformes. These two groups only occupied two ecological niches during the Mesozoic, living in water and on the ground, while the toothed enantiornithes were the dominant bird ...

Double-banded Plover
The double-banded plover (''Charadrius bicinctus''), known as the banded dotterel or pohowera in New Zealand, is a species of bird in the plover family. Two subspecies are recognised: the nominate ''Charadrius bicinctus bicinctus'', which breeds throughout New Zealand, including the Chatham Islands, and ''Charadrius bicinctus exilis'', which breeds in New Zealand's subantarctic Auckland Islands. Taxonomy A 2015 study found its closest relatives to be two other plovers found in New Zealand, the New Zealand dotterel (''Charadrius obscurus'', also called the New Zealand plover) and the wrybill (''Anarhynchus frontalis'', which the study found to be in the ''Charadrius'' clade). Description The double-banded plover is distinguished by a dark, grey-brown back with a distinctive white chest and a thin band of black situated just below the neck running across the chest along with a larger brown band underneath. During breeding season, these bands are more dominantly shown on the males ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wader
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Swan
The black swan (''Cygnus atratus'') is a large waterbird, a species of swan which breeds mainly in the southeast and southwest regions of Australia. Within Australia, the black swan is nomadic, with erratic migration patterns dependent upon climatic conditions. It is a large bird with mostly black plumage and a red bill. It is a monogamous breeder, with both partners sharing incubation and cygnet-rearing duties. The black swan was introduced to various countries as an ornamental bird in the 1800s, but has managed to escape and form stable populations. Described scientifically by English naturalist John Latham in 1790, the black swan was formerly placed into a monotypic genus, ''Chenopis''. Black swans can be found singly, or in loose companies numbering into the hundreds or even thousands. It is a popular bird in zoological gardens and bird collections, and escapees are sometimes seen outside their natural range. This bird is a regional symbol of both Western Australia, whe ...

Sarcocornia Quinqueflora
''Salicornia quinqueflora'', Synonym (taxonomy), synonym ''Sarcocornia quinqueflora'', commonly known as beaded samphire, bead weed, beaded glasswort or glasswort, is a species of succulent halophytic coastal shrub. It occurs in wetter coastal areas of Australia and New Zealand. Historically, people used to burn glassworts to collect the ashes. The ashes contained a high amount of soda in them, which was used to make soap and glass. This is thought to be how glasswort received its name. Description Beaded glasswort, ''Salicornia quinqueflora,'' is a species of succulent, salt tolerant plant. It grows as a small shrub, with a lifecycle of several years – which is also known as a perennial lifecycle. They are normally found near salt water bodies (along the coast or estuaries) and grow in a mat form along the ground. The stems are jointed and fleshy when young, but they dry out and appear woody when ageing. The young, fleshy stems are grey or green with sometimes red colouring al ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts o ...
