Native Vegetation Management Framework
The ''Native Vegetation Management: A Framework for action 2002'' is a Victorian strategy which aims to protect, enhance and revegetate Victoria's native vegetation. The Framework's main goal is to "achieve a reversal, across the entire landscape of the long-term decline in the extent and quality of native vegetation, leading to a net gain. The framework is notable for the inclusion of offsets, which allow authorised Land clearing in Australia, land clearing, providing there is a net gain in biodiversity, and for the fact that a monetary value is being placed on biodiversity. The "habitat hectare" has been defined as the trading currency of the framework, and provides a reliable and repeatable measurement of the quality of the native vegetation when correctly administered by an experienced assessor The trading in "habitat hectares" is a form of biodiversity banking, which occurs in the private market responding to the supply and demand of the available remnant vegetation.

Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...

Native Vegetation
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and rai ...

Land Clearing In Australia
Land clearing in Australia describes the removal of native vegetation and deforestation in Australia. Land clearing involves the removal of native vegetation and habitats, including the bulldozing of native bushlands, forests, savannah, woodlands and native grasslands and the draining of natural wetlands for replacement with agriculture, urban and other land uses. , of the vegetation which existed in Australia at the time of European settlement, approximately 87% remains. One estimate places the rate of rainforest of all types has been reduced by three quarters since the time of European settlement from eight million hectares to two million. Land clearing threatens native species including ground orchids and eucalyptus. Land clearing is an important environmental issue in Australia. Bans on land clearing have been placed by state governments. This policy largely permitted Australia to abide by its commitments to the Kyoto Protocol. Causes The underlying causes of land-cle ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity Banking
Biodiversity banking, also known as biodiversity trading or conservation banking, biodiversity mitigation banks, compensatory habitat, set-asides, biodiversity offsets, are conservation activities that compensate for the loss of biodiversity with the goal of biodiversity maintenance through a framework which allows biodiversity to be reliably measured, and market based solutions applied to improving biodiversity. Biodiversity banking provides a means to place a monetary value on ecosystem services. Typically this involves land protection, restoration, an/or enhancement. Biodiversity banking is often applied so that there is no "net loss of a particular biodiversity feature." According to the International Union for Conservation of Nature, by 2004, interest in voluntary biodiversity offsets was growing in the United States, Brazil, Australia, Canada and the EU. Experience suggested that industry, governments, local communities and conservation groups all benefit from biodiversity of ...

Supply And Demand
In microeconomics, supply and demand is an economic model of price determination in a Market (economics), market. It postulates that, Ceteris paribus, holding all else equal, in a perfect competition, competitive market, the unit price for a particular Good (economics), good, or other traded item such as Labour supply, labor or Market liquidity, liquid financial assets, will vary until it settles at a point where the quantity demanded (at the current price) will equal the quantity supplied (at the current price), resulting in an economic equilibrium for price and quantity transacted. The concept of supply and demand forms the theoretical basis of modern economics. In macroeconomics, as well, the AD–AS model, aggregate demand-aggregate supply model has been used to depict how the quantity of real GDP, total output and the aggregate price level may be determined in equilibrium.

Department Of Sustainability And Environment
The Department of Sustainability and Environment (DSE) was a state government department that managed water resources, climate change, bushfires, public land, forests and eco systems in the state of Victoria, Australia. It was created in 2002 when the Department of Natural Resources and Environment was divided into the Department of Primary Industries and the Department of Sustainability and Environment. The department supported and advised two Victorian ministers, the Minister for Environment and Climate Change, Ryan Smith, and the Minister for Water, Peter Walsh, and helped with the management and administration of their portfolios. The department secretary was Greg Wilson. It had 2700 staff working at 90 locations across the state. DSE was sometimes known colloquially as the "Department of Smoke and Embers" for its role in planned burns and bushfire management. The Department of Sustainability and Environment was merged with the Department of Primary Industries to form t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation In Australia
Conservation in Australia is an issue of state and federal policy. Australia is one of the most biologically diverse countries in the world, with a large portion of species endemic to Australia. Preserving this wealth of biodiversity is important for future generations. Animal habitats like reefs and forests must be preserved in order to preserve the population and diversity of animal species. Conservation is vital for future study and for field research to be taken, and because biological richness is an unmeasurable aesthetic that may be developed into commercial recreational attractions. According to Janine Benyus, the potential for advances in biomimicry in Australia is great because the extreme weather and conditions found here provide an excellent evolutionary incubator. Research on natural processes can only occur if the habitat is preserved and organisms continue to thrive. Federal and State governments manage protected areas and national parks; a number of non-governme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Issues In Australia
Environmental issue in Australia describes a number of environmental issues which affect the environment of Australia. There are a range of such issues, some of the relating to conservation in Australia while others, for example the deteriorating state of Murray-Darling Basin, have a direct and serious effect on human land use and the economy. Many human activities including the use of natural resources have a direct impact on the Australian environment. These issues are the primary concern of the environmental movement in Australia. Climate change Climate change is now a major political talking point in Australia in the last two decades. Persistent drought, and resulting water restrictions during the first decade of the twenty-first century, are an example of natural events' tangible effect on economic and political realities . Australia ranks within the top ten countries globally with respect to greenhouse gas emissions per capital. The current federal and state go ...

Economics Of Biodiversity
There have been a number of economic arguments advanced regarding evaluation of the benefits of biodiversity. Most are anthropocentric but economists have also debated whether biodiversity is inherently valuable, independent of benefits to humanity. Diverse ecosystems are typically more productive than non-diverse ones, because any set of species can never fully exploit all potential niches. Since human economic productivity is largely reliant on Earth's ecosystems, adequate bioproductivity needs to be maintained. The wealth of natural innovation found in biological organisms rivals all known technologies derived through synthetic means. A single human genome has some three billion bits of information but the human species also has many variations. There are many millions of species of life on the planet each with valuable information. Many chemical formulae and forty-five percent of all drugs have bio-origin . In the long run keeping genetic records of all species could, howev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Conservation In Australia
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...
