Land Clearing in Australia - Effects

Effects

Land clearing destroys plants and local ecosystems and removes the food and habitat on which other native species rely. Clearing allows weeds and invasive animals to spread, affects greenhouse gas emissions and can lead to soil degradation, such as erosion and salinity, which in turn can affect water quality.

The following table shows the Native Vegetation Inventory Assessment (NVIS) of native vegetation by type prior to European settlement and as at 2001-2004.

Vegetation Type Pre Settlement Total 2005 Total Percentage lost
Forest and Woodland 4,101,868 3,184,260 22%
Shrublands 1,470,614 1,411,539 4%
Heath 9,256 8,071 13%
Grassland 1,996,688 1,958,671 2%
Total Native Vegetation 7,578,204 6,562,541 13%

Effects Land Condition As land cover is crucial to land condition, land clearing exerts significant pressure on land condition. Removal of vegetation also leaves soil bare and vulnerable to erosion. Soil stability is essential to avoid land degradation.

Famous quotes containing the word effects:

    Oh that my Pow’r to Saving were confin’d:
    Why am I forc’d, like Heav’n, against my mind,
    To make Examples of another Kind?
    Must I at length the Sword of Justice draw?
    Oh curst Effects of necessary Law!
    How ill my Fear they by my Mercy scan,
    Beware the Fury of a Patient Man.
    John Dryden (1631–1700)

    Society’s double behavioral standard for women and for men is, in fact, a more effective deterrent than economic discrimination because it is more insidious, less tangible. Economic disadvantages involve ascertainable amounts, but the very nature of societal value judgments makes them harder to define, their effects harder to relate.
    Anne Tucker (b. 1945)

    If I had any doubts at all about the justice of my dislike for Shakespeare, that doubt vanished completely. What a crude, immoral, vulgar, and senseless work Hamlet is. The whole thing is based on pagan vengeance; the only aim is to gather together as many effects as possible; there is no rhyme or reason about it.
    Leo Tolstoy (1828–1910)
