Tecticornia Lylei
''Tecticornia lylei'', commonly known as wiry glasswort, is a small shrub with in the family Chenopodiaceae. It occurs in saline clay soils on the beds of and around the perimeter of salt lakes. The erect shrub can grow up to 1 m in height and 1.5 m wide, and has slender branches with very slender branchlets, its articles cylindrical, dull mid-green and about 3 mm long and 2 mm wide. The wiry glasswort flowers between November and June, with tiny flowers less than 3 mm across which fruit when pollinated. Listed as endangered in New South Wales and rare in Victoria and South Australia, ''T. lylei'' is threatened by trampling and overgrazing, vegetation clearing and stochastic events. Distribution and habitat ''Tecticornia lylei'' is an endangered species in NSW and rare in Victoria, with the numbers especially low in the once plentiful low open-shrubland in the Murray Darling Depression Bioregion. Requiring particularly saline soils to survive, it occurs on saline clay soils ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chenopodiaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal aggrega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterlogging (agriculture)
Waterlogging water is the saturation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail. In extreme cases of prolonged waterlogging, anaerobiosis occurs, the roots of mesophytes suffer, and the subsurface reducing atmosphere leads to such processes as denitrification, methanogenesis, and the reduction of iron and manganese oxides. All plants, including crops require air (specifically, oxygen) to respire, produce energy and keep their cells alive. In agriculture, waterlogging of the soil typically blocks air from getting in to the roots. With the exception of rice (''Oryza sativa''), most crops like maize and potato, are therefore highly intolerant to waterlogging. Plant cells use a variety of signals such the oxygen concentration, plant hormones like ethylene, energy and sugar status to acclimate to waterlogging-induced oxygen deprivation. In ...

Forage Harvester
A forage harvesteralso known as a silage harvester, forager or chopperis a farm implement that harvests forage plants to make silage. Silage is grass, corn or hay, which has been chopped into small pieces, and compacted together in a storage silo, silage bunker, or in silage bags. It is then fermented to provide feed for livestock. Haylage is a similar process to silage but using grass which has dried. Uses Forage harvesters can be implements attached to a tractor, or they can be self-propelled units. In either configuration, they comprise a drum (cutterhead) or a flywheel with a number of knives fixed to it that chops and blows the silage out of a chute of the harvester into a wagon that is either connected to the harvester or to another vehicle driving alongside. Towed harvesters are either single-chop, double-chop or precision-chop. Most larger machines also have paddle accelerators to increase material speed and improve unloading characteristics. Older machines were operated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubestock
Tubestock is the plural term for young plants which have been grown to the point where they are ready for either planting out in the field or potting on to larger pot sizes. Smaller, shallower pots (approx. 50mm in diameter x 80mm deep) are usually used to grow Tubestock in for the purpose of them being potted on to larger sizes. Larger, deeper pots (approx. 50mm square x 120mm deep) are generally preferred for planting out in the field, as in the case of Revegetation and Landscaping. The term tubestock generally refers to seedlings grown in individual pots (or Tubes) as opposed to smaller seedlings grown in cell-trays containing from 100 to 500 plants, which are referred to as "Plugs".

South Australia Department For Environment And Water
The Department for Environment and Water (DEW) is a department of the Government of South Australia. Created on 1 July 2012 by the merger of the Department of Environment and Natural Resources and the Department for Water as the Department of Environment, Water and Natural Resources (DEWNR), it was given its present name on 22 March 2018. It is responsible for ensuring that South Australia's natural resources are managed productively and sustainably, while improving the condition and resilience of the state's natural environment. Origins History of the environment portfolio in South Australia #On 23 December 1971, a new department called the ''Department of Environment and Conservation'' was created by the amalgamation of the ''Museum Department'' and the ''State Planning Office'' which was part of the ''Department of the Premier and of Development''. #On 18 December 1975, the ''Department of Environment and Conservation'' was renamed as the ''Department for the Environment' ...

Ellipse
In mathematics, an ellipse is a plane curve surrounding two focus (geometry), focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. It generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity (mathematics), eccentricity e, a number ranging from e = 0 (the Limiting case (mathematics), limiting case of a circle) to e = 1 (the limiting case of infinite elongation, no longer an ellipse but a parabola). An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution. Analytic geometry, Analytically, the equation of a standard ellipse centered at the origin with width 2a and height 2b is: : \frac+\frac = 1 . Assuming a \ge b, the foci are (\pm c, 0) for c = \sqrt. The standard parametric e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia Department Of Water And Environmental Regulation
The Department of Water and Environmental Regulation was formed on 1 July 2017, when the Department of Environment Regulation (DER) amalgamated with the Department of Water and the Office of the Environmental Protection Authority.

Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. ...

Murray Darling
Murray Darling is a wine region and Australian Geographical Indication which spans the Murray River and its confluence with the Darling River in northwestern Victoria and southwestern New South Wales. It was registered as a protected name on 16 June 1997. Murray Darling is the second-largest wine region in Australia. Vines were first planted there in 1888, around the time that irrigation schemes made it possible to grow fruit in the otherwise arid landscape through which this part of the Murray River flows.
