Digitaria Porrecta
''Digitaria porrecta'', commonly known as finger panic grass, is a species of perennial grass (Poaceae). Description ''Digitaria porrecta'' grows up to 60cm (23.6in) tall and has linear leaves that range from 5-15cm (1.9-5.9in) in length. Its ligules are 2-3 mm long and its racemes are up to 30 cm long. Distribution The species is native to Queensland and New South Wales, Australia. In Queensland, it occurs in the town of Nebo (south-west of Mackay). Additionally, it occurs in the Central Highlands and from Jandowae to Warwick. In New South Wales, it occurs from Graman and Croppa Creek to the Liverpool Plains near Coonabarabran. Conservation The species is listed as rare by the Nature Conservation Act 1992. As for most plants in this area, threats to ''Digitaria porrecta'' include loss of habitat from bushfires and urban expansion, trampling from grazing livestock, and invasive grasses such as ''Chloris gayana'' (Rhodes grass) and ''Urochloa panicoides ''Urochloa ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coonabarabran
Coonabarabran is a town in Warrumbungle Shire that sits on the divide between the Central West and North West Slopes regions of New South Wales, Australia. At the 2016 census, the town had a population of 2,537, Material was copied from this source, which is available under Creative Commons Attribution 4.0 International License.and as of 2021, the population of Coonabarabran and its surrounding area is 3,477. Local and district residents refer to the town as 'Coona'. History and description In 1817 the area was opened up by a Government-sponsored expedition. In 1818 John Oxley found Aboriginal people living here — later identified as the western language reach of the Kamilaroi clans (Gamilaraay is the spelling used by linguists). Kamilaroi people are still well represented in the region, having occupied Coonabarabran for approximately 7,500 years. In 1859 Lewis Gordon first proposed a town plan survey for Coonabarabran.

Bunchgrasses Of Oceania
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habita ...

Digitaria
''Digitaria'' is a genus of plants in the grass family native to tropical and warm temperate regions but can occur in tropical, subtropical, and cooler temperate regions as well. Common names include crabgrass, finger-grass, and fonio. They are slender monocotyledonous annual and perennial lawn, pasture, and forage plants; some are often considered lawn pests. ''Digitus'' is the Latin word for "finger", and they are distinguished by the long, finger-like inflorescences they produce. Uses The seeds are edible, most notably those of fonio ('' Digitaria exilis'' and ''Digitaria iburua''), '' Digitaria sanguinalis'', as well as ''Digitaria compacta''. They can be toasted, ground into a flour, made into porridge or fermented to make beer. Fonio has been widely used as a staple crop in parts of Africa. It also has decent nutrient qualities as a forage for cattle. Lawns The prevalent species of ''Digitaria'' in North America are large crabgrass (''D. sanguinalis''), some ...

Urochloa Panicoides
''Urochloa panicoides'' is a fodder grass originating in Southern Africa. Description This annual grass has decumbent or upright stems up to a meter long. It may root where its lower nodes contact the substrate. The leaves have linear or lance-shaped blades up to 25 centimeters long. They are hairless to somewhat hairy, and they may have hairs lining the edges. The inflorescence is composed of up to 10 racemes, each up to 7 centimeters long. The spikelets are solitary or paired. ''Urochloa panicoides'' can be confused with ''Urochloa setigera'', but the morphology of the spikelet is slightly different. Distribution This grass is native to southern Africa. It has naturalized elsewhere, including Australia, Argentina, India and the United States. Ecology It is most common on moist grasslands and lakesides up to an altitude of 2200 meters. Usage This grass is often used as a fodder for cattle and horses. It is now known as a weed and a potential seed contaminant. Diseases and p ...

Chloris Gayana
''Chloris gayana'' is a species of grass known by the common name Rhodes grass. It is native to Africa but it can be found throughout the tropical and subtropical world as a naturalized species. It can grow in many types of habitat. It is also cultivated in some areas as a palatable graze for animals and a groundcover to reduce erosion and quickly revegetate denuded soil. It is tolerant of moderately saline and alkaline soils and irrigation. Description This is a perennial grass which can reach one half to nearly three meters in height and spreads via stolons. It forms tufts and can spread into wide monotypic stands. The inflorescence is a single or double whorl of fingerlike racemes up to 15 centimeters long. Each spikelet in the raceme is a few millimeters long and contains one or two fertile florets and up to four sterile florets. Growing conditions Its seasonal growth is in the spring and summer and its rainfall requirement is 600–750 mm per year. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 comm ...

Urban Expansion
Urban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city." Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. Medieval suburbs suffered from loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The cost of building urban infrastructure for new developments is hardly ever recouped through property taxes, amounting to a subsidy for the developers and new residents at the expense of existing property taxpayers.

Bushfires In Australia
Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. Eastern Australia is one of the most fire-prone regions of the world, and its predominant eucalyptus forests have evolved to thrive on the phenomenon of bushfire. However, the fires can cause significant property damage and loss of both human and animal life. Bushfires have killed approximately 800 people in Australia since 1851, and billions of animals. The most destructive fires are usually preceded by extreme high temperatures, low relative humidity and strong winds, which combine to create ideal conditions for the rapid spread of fire. Severe fire storms are often named according to the day on which they peaked, including the five most deadly blazes: Black Saturday 2009 in Victoria (173 people killed, 2,000 homes lost); Ash Wednesday 1983 in Victoria and South Australia (75 dead, nearly 1,900 homes); Black ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liverpool Plains
The Liverpool Plains are an extensive agricultural area covering about of the north-western slopes of New South Wales in Australia. These plains are a region of prime agricultural land bounded to the east by the Great Dividing Range, to the south by the Liverpool Range and on the west by the Warrumbungle Range. The area is drained by the Namoi River and its tributaries, the Mooki River and the Peel River. There are many depressions, across the plains, which remain as lakes for long periods after heavy rain. These plains are unusual in that many steep hills arise suddenly from the plains. Towns in the Liverpool Plains include Gunnedah, Narrabri, Quirindi, Werris Creek and Tamworth. Smaller villages include Breeza, Carroll, Mullaley and Willow Tree. Most of the region nowadays comes under the jurisdiction of Liverpool Plains Shire Council. However substantial parts of the region also form part of the Gunnedah and Tamworth local government areas. History The Live ...
