Forests are often referred to as carbon sinks. This description is used because during
photosynthesis, carbon dioxide, the major greenhouse gas, is taken from the atmosphere and
converted into plant matter and oxygen.

Climate change has serious implications for Australia and overseas countries alike. Sustainable
land management is essential for effective greenhouse gas management; hence, it is important to
acquire data on land cover in Australia. Remotely sensed land cover changes are used in
calculations of our national emission levels, and data collected on a national scale will enable
governments to develop responses to land clearing.
