Hopkins Island
Hopkins Island is an island located in Spencer Gulf off the east coast of Jussieu Peninsula on Eyre Peninsula in South Australia approximately south-east of Port Lincoln. It was named by Matthew Flinders in memory of John Hopkins who was one of the eight crew lost from a cutter that capsized on 21 February 1802. Since 2004, the island has been part of the Memory Cove Wilderness Protection Area. Description Hopkins Island is located approximately south-east of Port Lincoln and west of Carrington Point, on the west coast of Thistle Island. The island is triangular in plan with its long axis being approximately and it maximum width being about . Its long axis is aligned in a north-east direction, similar to that of the north-west coast of Thistle Island. The island has an area of and has a maximum height of near its south west end. Access by boat is possible at the small beach on the island’s north coast. In 1910, it was described as "low-lying and somewhat bare". Guano d ...

Spencer Gulf
The Spencer Gulf is the westernmost and larger of two large inlets (the other being Gulf St Vincent) on the southern coast of Australia, in the state of South Australia, facing the Great Australian Bight. It spans from the Cape Catastrophe and Eyre Peninsula in the west to Cape Spencer and Yorke Peninsula in the east. The largest towns on the gulf are Port Lincoln, Whyalla, Port Pirie, and Port Augusta. Smaller towns on the gulf include Tumby Bay, Port Neill, Arno Bay, Cowell, Port Germein, Port Broughton, Wallaroo, Port Hughes, Port Victoria, Port Rickaby, Point Turton, and Corny Point. History The first recorded exploration of the gulf was that of Matthew Flinders in February 1802. Flinders navigated inland from the present location of Port Augusta to within of the termination of the water body. The gulf was named ''Spencer's Gulph'' by Flinders on 20 March 1802, after George John Spencer, the 2nd Earl Spencer. The Baudin expedition visited the gulf after Flind ...

Marsh Saltbush
''Atriplex paludosa'', commonly known as marsh saltbush, is a species of saltbush endemic to Australia. Description It grows as an erect shrub up to a metre high. Leaves are oval in shape, one to four centimetres long, and 2 to 15 millimetres wide. Taxonomy It was first published by Robert Brown in 1810 based on specimen material collected at Port Dalrymple, the site of present-day Launceston, Tasmania. Four subspecies are recognised: ''A. paludosa'' subsp. ''paludosa'', ''A. paludosa'' subsp. ''baudinii'', ''A. paludosa'' subsp. ''cordata'' and ''A. paludosa'' subsp. ''moquiniana''.

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 ...

Little Penguin
The little penguin (''Eudyptula minor'') is a species of penguin from New Zealand. They are commonly known as little blue penguins or blue penguins owing to their slate-blue plumage and are also known by their Māori name . The Australian little penguin (''Eudyptula novaehollandiae'') from Australia and the Otago region of New Zealand is considered a separate species by a 2016 study and a 2019 study. Taxonomy The little penguin was first described by German naturalist Johann Reinhold Forster in 1781. Several subspecies are known, but a precise classification of these is still a matter of dispute. The holotypes of the subspecies ''E. m. variabilis'' and ''Eudyptula minor chathamensis'' are in the collection of the Museum of New Zealand Te Papa Tongarewa. The white-flippered penguin (''E. m. albosignata'' or ''E. m. minor morpha albosignata'') is currently considered by most taxonomists to be a colour morph or subspecies of ''Eudyptula minor.'' In 2008, Shirihai treated th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grazing
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to roam around and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land unsuitable for arable farming. Farmers may employ many different strategies of grazing for optimum production: grazing may be continuous, seasonal, or rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site, but studies show that the greatest benefit to biodiversity comes from removing grazing animals from the landscape. ...

Pasture
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed with extensive practices like co ...

Rat's-tail Fescue
''Vulpia myuros'', the annual fescue, or rat's-tail fescue, is an annual grass species of the genus ''Vulpia''. It was probably originally native to Eurasia, but it can now be found nearly worldwide as a naturalized species. In the United Kingdom it forms dense, even swards of fine, hair-like stems in recently disturbed habitats. It is often eventually displaced by perennial grasses. Invasive species ''Vulpia myuros'' is considered a noxious weed and invasive species in places where it is not native, especially in areas with a Mediterranean climate. For example, it is widespread in California California is a U.S. state, state in the Western United States, located along the West Coast of the United States, Pacific Coast. With nearly 39.2million residents across a total area of approximately , it is the List of states and territori ..., where it is now a dominant species in many types of grassy habitat.

Grasses
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, primari ...

Mesembryanthemum Crystallinum
''Mesembryanthemum crystallinum'' (the common, 'crystalline' or 'crystallinum' iceplant, or simply 'iceplant') is a species of annual/perennial, succulent flowering plant in the "mesemb" genus of the Aizoaceae family. A true Mediterranean-climate grower, this prostrate groundcover is native to coastal North Africa and Sinai, the Levant and maritime Southern Europe, and several Mediterranean and North Atlantic islands, as well. The plant is covered with large, glistening bladder cells, or water vesicles, hence its many common names such as crystallinum iceplant, crystalline iceplant or iceplant. Description ''Mesembryanthemum crystallinum'' grows creeping stems, from in length. The leaves are long. It flowers from March to October. The many-petalled flowers, across, open in the morning and close at night, and are pollinated by insects. The species is covered with enlarged epidermal cells, called "bladder cells", the main function of which is to reserve water. The plant ca ...

Weed
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. This introduces the concept of humans and their goals in a particular setting.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the aim is growing crops or pastures of a single species, or a mixture of a few desired species. In such environments, other plant species are considered undesirable and therefore a weed. Besides, some weeds have undesirable characteristics making them a plant pest in most human settings.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Spri ...
