Lower Ringarooma River
The Flood Plain Lower Ringarooma River wetlands is a wetland site comprises the floodplain of the lower Ringarooma River in north-eastern Tasmania, Australia. In 1982 it was designated a wetland of international importance under the Ramsar Convention. Description The Ramsar site has an area of . It lies between the towns of Tomahawk to the west and Gladstone to the south-east. It is a sandy floodplain, flat and low-lying, with an elevation of less than above sea level. Geologically, it consists of Quaternary clays, sands and gravels with silty clay soil overlying deep grey sands. The silt is derived from erosion in the river catchment caused by tin mining. The average annual rainfall is 625–750 mm. Flora and fauna The site is vegetated with shrubland and tussock grassland and surrounded by woodland. Several plants that are rare or threatened in Tasmania, including '' Centipeda minima'', '' Polygonum strigosum'', ''Lythrum salicaria'' and ''Villarsia exaltata'', occ ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many stems. Tall shrubs are mostly 2–8 m high, small shrubs 1–2 m high and su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Waterfowl Hunting
Waterfowl hunting (also called wildfowling or waterfowl shooting in the UK) is the practice of hunting ducks, geese, or other waterfowl for food and sport. Many types of ducks and geese share the same habitat, have overlapping or identical hunting seasons, and are hunted using the same methods. Thus it is possible to take different species of waterfowl in the same outing. Waterfowl can be hunted in crop fields where they feed, or, more frequently, on or near bodies of water such as rivers, lakes, ponds, swamps, sloughs, or oceanic coastlines. History Prehistoric waterfowl hunting Wild waterfowl have been hunted for food, down, and feathers worldwide since prehistoric times. Ducks, geese, and swans appear in European cave paintings from the last Ice Age, and a mural in the Ancient Egyptian tomb of Khnumhotep II ( BCE) shows a man in a hunting blind capturing swimming ducks in a trap. Muscovy ducks were depicted in the art of the Moche culture of ancient Peru by 200 BCE, and ... [...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. ...

Livestock
Livestock are the domesticated animals raised in an agricultural setting to provide labor and produce diversified products for consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, goats and pigs. Horses are considered livestock in the United States. The USDA classifies pork, veal, beef, and lamb (mutton) as livestock, and all livestock as red meat. Poultry and fish are not included in the category. The breeding, maintenance, slaughter and general subjugation of livestock, called '' animal husbandry'', is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and time periods. It continues to play a major economic and cultural role in numerous communities. Lives ...

Waterbird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys and sea eagles, hunt aquatic prey but do not stay in water for long and lives predominantly over dry land, and are not considered water birds. The term waterbird is also used in the context of conservation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.) Merr. * ''Villarsia goldblattiana'' Ornduff * ''Villarsia manningiana'' Ornduff Southeast Asia: * '' Villarsia cambodiana'' Hance (synonym: ''V. rhomboidalis'' Dop) Eastern Australia: * ''Villarsia exaltata'' (Sol. ex Sims) G.Don (synonym: ''Liparophyllum exaltatum'') Western Australia: * '' Villarsia c ...

Lythrum Salicaria
''Lythrum salicaria'' or purple loosestrifeFlora of NW Europe''Lythrum salicaria'' is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife and purple Lythrum. This herbaceous perennial is native to Europe and Asia, and possibly Australia. Etymology and other names The generic name ''Lythrum'' is derived from the Greek ‘lythron’, meaning blood, in reference to the flower colour in some species.Gledhill D. 1985. ''The Names of Plants''. Cambridge University Press However, Pliny (A.D. 23-79) stated that ''Lythrum'' is named for Lysimachus, an army general and friend of Alexander the Great. ‘’Lysimachus’’ is derived from the Greek ‘’lysis’’, meaning ‘’loosing’’ and ‘’mache’’, meaning strife.

Polygonum Strigosum
''Polygonum'' is a genus of about 130 species of flowering plant in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass (though the common names may refer more broadly to plants from Polygonaceae). In the Middle English glossary of herbs ''Alphita'' ( 1400–1425), it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat (''Fagopyrum esculentum'') has sometimes been included in the genus as ''Polygonum fagopyrum''. Former genera such as ''Polygonella'' have been subsumed into ''Polygonum''; other genera have been split off. The genus primarily grows in northern temperate regions. The species are very diverse, ranging from prostrate herbaceous annual plants to erect herbaceous perennial plants. ''Polygonum'' species are occasionally eaten by humans, and are used as food plants by the larvae of some Lepidoptera species – see list. Most species are consider ...

Centipeda Minima
''Centipeda'' is a genus of flowering plants in the daisy family, Asteraceae. The genus is primarily native to Australia and New Zealand, with a few species extending the range northward into Asia and across the Pacific to southern South America. Species Research and biological activities Volatile oils from '' Centipeda minima'' have been shown to modulate anti-inflammatory action by inhibiting inflammatory cytokines in a rat model. In a related study, ''C. minima'' eased allergic rhinitis by slowing the infiltration of eosinophils and the proliferation of mast cells. A comprehensive investigation of the GC-MS chemical profile of '' C. cunninghamii'' and its biological activity showed that this species' extract contains novel compounds that possess anti-inflammatory and antioxidant properties. Phylogeny In 2012, Nylinder et al. published an estimation of the species tree phylogeny of the Australian/New Zealand genus ''Centipeda'' (Asteraceae) based on nucleotide sequence dat ...

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...
